High end 4.5" speaker.

Availability: In stock

* Required Fields



From the designer: I kind of wanted to name the speaker series after the Honda S2000. It just reminds of them in the way that they are small and high-tech looking, and really open up when you push them hard. I’m enjoying these woofers. Even though they model similarly to several other woofers, for some reason they seem to dig deeper. They're going to sound amazing. Even as a bookshelf, I think people will be pretty surprised by the sound they put out. Although it's a 4 Ohm woofer, I honestly don't think most amps would have trouble driving the finished speaker.


Product Notes: 

We wanted to make a small speaker that most people could fit just about anywhere.  We also wanted it to be a good step up from your typical budget style speaker without breaking the bank.  The 4.5" cast frame woofer has a great overall look and the first thing you'll notice is the attention to detail put towards making this woofer.  Once you listen to them you'll hear why Paul enjoyed desiging a speaker using these components.



Product Highlights:

  • Wavecor tweeter for smooth highs.
  • Cast frame 4.5" woofer with light weight carbon fiber cone.
  • Optional flat pack is 1/2" thick Baltic birch.
  • Surpising output for it's size.
  • Timbre matched to the dual woofer MTM version (coming soon).


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.

  1. Another winner from Paul C. Strong bass and clear imaging. Great all around performer. review by Ceiol on 2/10/2018

    The s2000 is better all around than the overnight sensations and rivals the speedsters. The wavecor tweeter is a winner and provides accurate and precise imaging. The CF woofer is strong and belts out warm, filling bass. Wider sweet spot than the speedster, though a little less airy on the highs.

    Go for it, build the s2000 speakers. You’ll love them.

Specific S2000 Assembly Notes:

Your enclosure should be built with 1/2" thick material to the dimensions listed.  If built from Baltic birch, you do not need a brace inside this sized cabinet.  It is recommended that you lightly fill your enclosure with polyfill withough blocking the port.


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.

     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'.
