Quick Overview

$131.93

Availability: Out of stock

Details

From the designer:   These turned out great! They should slot in well as an upgrade to the Overnight Sensations. The're really nice low-distortion drivers, and they just sound effortless, even when pushed really hard. I honestly don't know where the limit is on these, but they were playing at 95 dB at my house and didn't seem to be breaking a sweat.  Like the TM, the harder you drive them the better they sound. Bass is surprisingly deep, just like the TM version. It should complement the other one perfectly.

 

Product Highlights:

  • Wavecor tweeter for smooth highend.
  • Cast frame 4.5" woofers with light weight carbon fiber cones.
  • Can also be used as a center channel.
  • Timbre matched to the single woofer version.

 

Minimum order is 2 speakers: If you ordered one in the past and need one for a center, please contact me. Kits are sold as full kits, sorry no substitutions or subtractions. Don't forget binding posts, terminal cups, or speaker spikes if you need them because they can be shipped for free with any kit or flat pack purchase.

Shipping Note: Most speaker kits currently ship for free, but flat packs normally do not.  We try to get your order packaged and shipped in 5-8 days depending on how many orders have come in.  Please read the 'Frequently Asked Questions' section for more information.

  1. Amazing value for these small speakers review by Orange DIYer on 5/22/2023

    I bought two of these two years ago and never got to finish them. Recently I gave them to my 12 year old. Under my tutelage he was able to solder the crossovers, and we assembled the flatpacks in less than a day. Took him a while to get the paint in decent shape, we just used a good primer, tons of sanding and two shaker cans of green. My son assembled these with some minor help. They look really good on his computer desk. He connects his Nintendo Switch to his screen and these speakers and plays Zelda on it. Amazing, I'm sort of jealous for giving him these. I intended to use them for my 2 channel vinyl setup i my office. I might just buy two more in the future when they are in stock again.

    I wish I can attach photos here....

    We love these, we love DIYSG kits! Go Erich!

    I absolutely love these speakers. For their size they are truly amazing. I currently power them with a Dayton Audio apa150 amp. I use them almost exclusively for music but have taken them outside for an outdoor movie and they did great out there. Very clear and effortless sounding. The build was super easy. I plan to make another set in the future.

    These are amazing. I got 3 of them because everything else was sold out and couldn't wait to start a new project. Well they arrived today and already have them built, stained, wired and running some of everything from bassnector (edm) to incognito (jazz) and every genre in-between. Well ill say this, I'm happy I went with these. These are a must have yall!

  4. Sublime! review by T on 7/7/2020

    I am in the middle of restoring the outside of an old 1940's console radio and decided to build one of these speakers and operate in mono connected to an Alexa all stuffed inside this console. The sound for a single speaker is very true to what the artists intended for us to hear. I have been listening to this speaker in my shop and every single genre of music I throw at it the speaker has yet to let me down. I tend to prefer 70s and 80's music and anywhere from Rock n Roll to more of a hip hop style Bruno Mars offers up. I have even went as far as to play classical, jazz and reggae all of which sound perfectly balanced. Running as a mono channel obviously lessens to the sound stage a tad since I don't have a separate left and right channel for the music to run through and I can only imagine how massive these sound while operating as a pair. I have purchased and listen to a lot of speakers but this is the first DIY I have built and listen to. Did not disappoint and I am getting ready to build another set for a family member and maybe upgrade to something a tad bit larger for my workshop though its not needed at all.

  5. Easy build, great sound review by ProfessorSabre on 9/9/2019

    Built three of these to serve as L-C-R for a mix of music and home theater use in an 18 sq ft. room with an Onkyo 95-watt/channel receiver paired with a 12" sub.

    Sound is clean and crisp though other comments that the speakers sound their best at higher volumes is accurate. They put out a nice amount of base so you can crossover the sub pretty low as your setup demands. Sound stage is wide enough to fill the room without any muddy spots.

    Construction was simple, especially with the specially designed PCB board. Just note that there isn't anyplace to zip-tie the larger coil down so you may want to hot glue it before soldering. Don't make the same mistake I did and use the rabbited back panel as alignment to keep the sides square during the initial glue up. The speakers are not a permanently closed design when I'd have preferred to hold the back panel in with screws for repair/adjustment access. No need for speaker or port gasket tape, the pre-routed baffles fit perfectly with no rattle.

    Overall a great speaker for the price, ease of construction, and ease of finish with the clean baltic birch ply.

    This was my first time ever doing a DIY project like this and I have to say I am more than pleased with everything.

    Starting from Erich responding to my every stupid question (remember, I've never done this before) to the quality of the finished product.

    The packaging is so sturdy, could withstand a drop from a truck. The way Erich and the team have made the kit is so easy to use. Quality of the sound is awesome and I'm definitely going to do more of these for the sake of "practice makes things perfect"

  7. HT center channel review by djg on PE Tech Talk on 10/6/2018

    I recently drastically downsized my HT speakers. I had a pair of S2000 TMs, figured see how they sound. After large towers with 4 7" woofers and a 7" woofer MTM center, I was very surprised at how nice the little S2000s sounded, so I ordered a S2000 MTM for my new center channel speaker. Built in 2 days with a painted baffle and Danish oil on the birch. I initially hooked it up in my 2.1 PC sound for testing and initial impressions, it was much louder than the TM on the other channel. Loud and clear.

    I then installed it in my HT. Very clear dialogue, really noticeably better than the mismatched TM I had temporarily put in the center. So I can recommend a front HT system of S2000 TMs and a MTM. I imagine 3 MTMs would really surprise a lot of people.

    I can't give a detailed review of a stereo pair. In my usage, the S2000 really shines.

    IMHO, these are winners, TM and MTM. Definitely worth continuing, the new and vastly improved Overnight Sensations.

  8. Wonderful Desktop Monitors review by Popeye714 on 7/18/2018
    Design
    Performance
    Value

    I chose the s2000 MTM's b/c I wanted a desktop monitor for music with a strong mid-bass section, a small(ish) footprint, and attractive to look at on my desk. I can't say this for all of the decisions in my life :), but this was a good one! As previously stated, very neutral overall sound quality with a slight bass lean. The highs are relatively detailed w/o sounding fatiguing. Yes, I've heard better, but nowhere near this price range. I'm sure this comment is starting to get old. But, the bass response from these things is rather impressive. To give you an idea. I have an extra sub sitting around that I planned to use with them. After a few tracks, the sub was sent home. For my purpose, it simply wasn't needed. The strange thing I noticed is that the bass/mid-bass just gets punchier as they are turned up louder. Perhaps I am just impressed that those little mids can keep up? Anyhow, I digress. Enjoying them immensely. I did take the time to cover them with a zebra-wood veneer and they look great on my desk. A very attractive design. Take the time to put a nice finish on them and you will not regret it. Highly recommended.

  9. Great all around speakers review by Simyn on 7/2/2018

    These are nice little speakers in a small package, competent for movies and music.

    I built them using the flat pack. It was very precisely cut so it glued together easily. You could easily make due with just a few clamps because of the small size. Cross-over was easy to layout and solder without a PCB even for a first timer. Enclosure is stuffed with poly and I removed the port extension and just used the main section. That makes it ever so slightly shorter than the specs. I sealed and stained the birch flat pack directly with a walnut color and it came out looking nice. Easy to get a good finish without the expense of veneer or trouble of paint.

    Once finished I was impressed with the sound. The first thing you notice is the bass coming out of such small speakers. They can handle most types of music easily even without a subwoofer. They don't have the lower range for pipe organs or dubsteb, but pretty much everything else within reason is all good. Of course for movies, cross over to a sub in the 60-80Hz range and they have enough punch to integrate even with a larger sub.

    They throw a pretty wide sound stage, with good detail and imaging. Highs are detailed but are not fatiguing to listen to at high volumes and the mid-range is clear. Powered with 105W per channel they get satisfyingly loud in a medium sized room. I think they might be a little strained in a large great room or something like that.

    I have a pair of NHT Super One 2.1's which are a bit more expensive than these. The S2000s have a comparable upper end, but with much more bass. Without making a detailed comparison they sound at least as good as the NHTs in their own way.

    There are other designs both DIY and commercial that might be better suited for specific applications, but if you are looking for something that's good at most everything (desktop, 2 channel, HT) these would be a good choice.

    I built the Overnight Sensations last month for my mom. Great little speaker. They’re blown away by these. Just finished to today as a gift for a friend and very pleased.

    Very capable speaker...neutral with a slight bass lean. Great wide soundstage. Can stand on their own without a sub as long as one is reasonable. Magical with female vocalists.

  11. High(-ish) Sensitivity Magic. review by John Booty on 3/23/2018

    These are phenomenal.

    Bass is clear and deep, down into the 40hz range with a little help from room placement fairly close to a wall. Hip-hop sounds phenomenal. I tested with a wide variety of genres and these really have no weaknesses.

    Highs and mids are clear and detailed. Perhaps not the best I've heard, but quite nice and very good for this price range.

    Off-axis performance is quite good. There is a sweet spot for sure, but you don't pay a harsh penalty as you move about the room.

    Where these shine is their ridiculous output and sensitivity, given their relatively compact size. I have no idea where the limit of these speakers is. I pushed them hard with my Emotiva A-100 (a solid, low-distortion 80wpc into 4ohms) and these sounded like they wanted more. If you have never heard relatively high-sensitivity speakers like these, you may not know what you're missing. High-sensitivity speakers really make the music come alive, particularly with well-recorded music with a high dynamic range.

    Only time these speakers complained was with some particularly punishing tracks with bass down into the 20-30hz range. They didn't audibly distort or anything, but I sort of felt bad for the helpless speaker cones as they flopped around and tried to play frequencies they weren't physically capable of playing. Please understand: tracks like that are rare, and nothing you've ever heard on the radio has real content that deep.

    ~~ Recommendations ~~

    1. I tested with music only but unless you have a very large room, these speakers could be home theater monsters in anything resembling a typical middle-class residential home.
    2. If you cross them over to a subwoofer, use a fairly low crossover point so you don't waste their extremely potent midbass. Do NOT cross them any higher than 60hz, or I will find you and hurt you. =)
    3. For music use, you probably don't need a subwoofer.

    ~~ Compared To Other DIY Speaker Kits ~~

    Overnight Sensations MTM: Please, please please consider the S2000 instead. I like the OS MTM but for slightly more money, the S2000 MTM is better in every way.

    Classix II: The Classix II have a wider soundstage and more bass extension. In a small room at low to moderate they may be preferable to the S2000. However, the S2000 dwarf them when it comes to sheer output and power handling.

    Speedsters: In a small room, the Speedsters' on-axis performance is unrivaled in this price range... the ribbon tweeters are magic and the woofers are tiny miracles. However, their narrow dispersion (and therefore poor off-axis performance) makes them a tough sell.

    C-Notes: They're an insane value. At moderate volumes they compete well with the S2000 MTM. If you don't need the extra output of the S2000, the C-Notes may be a better choice, particularly if crossed over to a subwoofer.

    Ares TM/MTM and Apollo TM/MTM: Sadly I haven't built/listened to these. The Ares TM is certainly a very interesting alternative; going "by the numbers" it has deeper extension but is a full 6dB less sensitive.

Specific S2000 MTM Assembly Notes:

Your enclosure should be built with 1/2" thick material to the dimensions listed with one horizontal 'window pane" style brace.  It is recommended that you lightly fill your enclosure with polyfill or line the internal walls with a thin acoustic foam without blocking the port.  The ports are adjustable so you can do some experimenting on the tuning with them at 6" long, but the original design used them at 4.75".  You want to glue them at the shortest length so that they're about 4.75" long.

 

Recommended Tools and Supplies:

  • Quality wood glue like TiteBond.
  • At least 2 clamps 16" wide or bigger.  
  • Soldering Iron and solder unless there is an optional assembled crossover for your kit.
  • Wire cutters
  • Screwdriver
  • Drill to predrill all screw holes.
  • Sanding block or power sander.
  • About 8' of speaker wire to connect your woofers and tweeter to the crossover board.

 

General Tips:

    Crossover Assembly: 

  • VERY IMPORTANT - Inductors are the parts that look like small rolls of copper wire. Notice that the two ends of wire are silver and have been 'tinned' with solder. Those are the parts of the inductor that you should be soldering to, so don't cut it off to get to the copper colored portion.  Inductors should not be installed directly next to each other on your board.
  • None of the crossover parts have a positive or negative side so it doesn't matter which way they are facing when you assemble your crossover. 16-18 gauge wire is thick enough to use for your crossover or to go from your crossover board to the woofer or tweeter.
  • Your crossover can be assembled on a thin piece of MDF or pegboard if the kit doesn't come with a circuit board.
  • It doesn't matter where you put the crossover inside your speaker.  You could mount it on the outside if you wanted to.  
  • Normally you wire red wires to positive and black wires to negative.  If (and only if) your crossover schemtaic has a note saying 'Inverted Polarity', that means you need to connect the negative from the crossover to the positive on the tweeter and positive from the crossover to the negative on the tweeter.  This is only done on some tweeters, not woofers.
  • Click Here for a good assembly video by Matt Grant.

     

     Screws and Gaskets:

  • Predrill all screw holes with a bit that's slightly smaller than your screws to prevent the wood from splitting.  Most screws are #8 panhead and you can use a 7/64" or 1/8" drill bit.  Overnight Sensations use a #6 panhead so you can use a 3/32" bit.
  • VERY IMPORTANT:  Protect your woofer or tweeter when installing screws because you don't want the screwdriver to slip and puncture one of your components....that will ruin your day!  Consider putting your free hand next to the screw to cover up the edge of the woofer or tweeter.
  • If your kit comes with gasket tape, it should be applied to the back of the waveguide. Peel the paper off the back to expose the sticky side and slowly work it around the perimeter on the back side of the part.  Some woofers will need gasket tape as well.

   

     Stuffing or Lining the Speaker Cabinet:

  • If your speaker or subwoofer is a sealed cabinet, most designers recommend that you lightly fill the inside with polyfill (pillow stuffing).  If you don't have polyfill, then you can line the walls with 1" - 1.5" thick light weight open cell foam (like acoustic foam) or fiberglass insulation.  You can also use 2-3" recyled denim insulation that can be bought at Home Depot.
  • It's okay to cover up your crossover with the polyfill, insulation, or foam.
  • If you're using a ported enclosure you should lightly fill the cabinet with polyfill and be sure not to block the ports.  If you do not have polyfill then line the walls with 1" - 1.5" thick open cell foam (like acoustic foam), 2" - 3" of denim insulation, or 2" - 3" thick poly batting.
  • Some of the speaker designers like to lines the walls of their ported enclosures with a 1" - 1.5" acoustic foam, and then lightly fill the remainder of the cabinet with polyfill.  If this is a required method, it will be listed at the top of the page under 'Assembly Notes'.
