A hidden gem for high efficiency 2 channel listening review by rtfly193 on 12/28/2025The intended use case for this speaker is of course home theater, but it might just be the best bargain for 2 channel music listening.
Build Experience
The kit is easy to work with and well thought out. The CNC-cut panels fit together cleanly, and nothing required force or guesswork. Assembly is straightforward, and a realistic timeline is two to three weekends, depending on how much time you spend on finishing.
The crossover boards are thick and clearly labeled, and the solder pads are generously large. Buy the boards when ordering the kit, the small additional cost is well worth it.
Efficiency & Amplifier Pairing
At around 99 dB sensitivity, the 815LX works well with low-powered amplifiers, including tubes. You don’t need much power to get satisfying output, and the speaker never feels strained.
I ran them with a Fosi Audio ZA3, using a miniDSP 2x4HD upstream. This setup had no trouble driving the speakers and made it easy to adjust overall balance.
Sound
The default voicing is a bit on the bright side, which makes sense given the speaker’s home theater origins. That said, it’s easy to adjust. Adding an adjustable L-pad to the compression driver allows you to reduce the top end to better suit music listening or personal preference.
Bass extension is good without any processing, and the speaker can play loud cleanly. With some DSP, it can go further. Using a low-shelf filter, I was able to get a flat in-room response down to about 26 Hz. Bass impact is strong and controlled, with no obvious distortion at normal listening levels.
Imaging & Presentation
Imaging is stable and well defined, and the soundstage has a convincing sense of scale. It adds a particular authenticity to live recordings in particular. The center image stays fixed in place even as you move out of the sweet spot, thanks to the carefully designed horn and waveguide.
Closing Thoughts
Matt and Erich did an excellent job of balancing performance, usability, and value with the Titan 815LX. It’s easy to build, flexible to tune, and works just as well for music as it does for home theater. If you’re interested in high-efficiency speakers and don’t mind building a kit, this one is worth considering. -
What a Incredible budget speaker for dedicated home theater !!!! review by Alexandre on 7/1/2025
I recently installed the DIYsoundgroup Titan-815LX speakers in my dedicated home cinema—paired with Volt 10 speaker for surround, two 18″ UM18 subwoofers, and two LaVoce subs—and I couldn’t be happier with the results. Before this project, I’d never even heard of DIYsoundgroup. I was on the hunt for an upgrade to my setup, but everything on the market felt outrageously expensive. It was actually ChatGPT that first pointed me toward the Titan-815LX, and once I dug into the unanimous positive feedback online, I decided to take the plunge.
From the moment I powered up my Anthem AVM 70 preamp into the Monolith X9 amplifier, the Titan-815LX delivered a level of dynamics I hadn’t experienced before. Their clarity in the midrange and the seamless integration with my two UM18s for deep bass (60–120 Hz) and LaVoce subs for infrasonic extension takes the low end to a whole new plane. I’ve set up a gently descending EQ slope of –4 dB to tame the top end, and the result is nothing short of musical—every explosion, every whisper in a Dolby Atmos mix feels rich and alive.
And what can I say about Eric’s support and the wealth of information he provides? He’s incredibly responsive and genuinely helpful—always ready to answer questions or guide you through a tweak. That level of personal attention is rare.
Before this build, my front channels were driven by Klipsch and JBL speakers, and I can honestly say it’s like night and day now. The Titan-815LX brings a level of finesse and musicality those systems simply couldn’t match.
In Dolby Atmos content, the soundstage blossoms with pinpoint imaging and effortless headroom. Dialogue sits perfectly in the center channel, effects swirl overhead, and the bass impact is as tight as it is powerful. I’m genuinely not disappointed—these Titan-815LX transformed my system into a truly immersive theater without the premium price tag of name-brand alternatives. If you’re looking for high-end performance on a reasonable budget, the DIYsoundgroup Titan-815LX deserves serious consideration.
Also very easy to assemble. The custom circuit are very helpfull. Thanks again -
Incredible speaker review by Bobby on 1/27/2025
The titan 815s are incredible. For the price you can get them for it's a no brainer to buy them. They easily outcompete speakers in their price bracket and several brackets above. They have a massive sound stage, excellent instrument separation and the best phantom center I've ever heard in stereo. My wife even said they sound better than our previous speakers when I was testing them before EQ. They are detailed and have that fun airy/alive sound quality to them at the same time. Their particular strengths in music are female vocals and guitars. On my AVR they can play at ear bleeding levels without breaking a sweat or even hinting at the possibility of distorting.
I bought the flat packs and wave guide bracket because these are in our living room and I needed as much spousal approval factor as possible. They look professionally built and were simple to assemble. The hardest part was figuring out how I wanted the circuit boards to sit in the box to hide them, but they could easily mount behind the wave guide on the brackets (wife didn't want to see them so I did the extra work to hide them). Everything with these speakers from the packaging to the materials utilized are high quality and speaks to the dedication Erich has put into DIYSG.
I wanted to give some thoughts on how these speakers sound compared to what I've had experience with in my own home. I've gone from andrew jones polk 5.1 bookshelf system to an SVS ultra 5.1 system and then upgraded my LCR to polk r700s with a 1099 center. The andrew jones are an obvious step up from a sound bar and are likely good enough for 90% of people. The SVS ultras were very detailed and critical, but lacked that movie theater quality and sounded constrained/small in my larger living room likely due to their lower sensitivity. The SVS were also the best looking speakers I've had. The polk r700s were a step up in sound quality across the board from the SVS ultras, but finicky to get good imaging with since they have mediocre horizontal dispersion characteristics due to the ring radiator style tweeter beaming effect. They seem best suited for a 2 channel listening experience in a dedicated space. The 1099 had an airiness and theater type of sound with the same amount of detail as the SVS without the constrained feeling. When listening in surround sound mode the superiority of the 1099 really shined compared to the SVS center it replaced. The 815s are in another league compared to the 1099. The same amount of detail, but the soundstage is on another level. Right now I'm in a 21ftx24ft living room with a 7.3.4 system made up of titan 815s for L/R, 1099 center, SVS ultras for surrounds and polk omw3s for atmos. The 815s have significantly improved the overall sound of my system compared to the polk r700s they replaced and which I still love. I've also listened to B&W 804 Ds in a dedicated listening room with amplifiers/CD and vinyl players more expensive than most of my current set up. It made me a firm believer in the law of diminishing returns with audio equipment. I doubt you could find a meaningfully better sound experience beyond the titans for home theater and music listening buying more expensive speakers (spend the money on room treatment/comfy couches/high quality popcorn).
For me, the 815s sound best with 5-10 degrees of toe in placed 5.5 feet from center with my main listening position 10ft away from the TV.
If you have the ability to physically put them in your home/theater buy them the next time they're available because you won't be disappointed.
