Rated 5 out of 5 by from TriTrix MTMAssembly video for the crossovers was tremendous. CNC cuts on the MDF cabinets were very precise, making assembly using the included manual error free. It was not clear where to mount the crossovers in the cabinet, but my best guess and info from the speaker system designer's web site matched up. I am in the process of applying a piano black finish to the enclosures, then, WAHOO! pop the speakers in with the push on connectors that I used on wires leading from the crossovers, pop in the bolts, and crank it up!

Rated 5 out of 5 by from Real Music for less tht the price os a used car.These are exceptionally good speakers for the price. I’ve been an audiophile nerd type for many years and have owned a lot of equipment with a wide range of prices. I’ve played with designing and building speakers as well and having used some great testing software/hardware in the process. I will never be a world class engineer but I did learn enough from the engineering and from the hobby side to know these are an amazing value. You could spend a lot more to get a lot less. These seem to measure quite well with limited tools I have now have but most importantly they are not “tuned” to the big box nasty yell on you face to get your $ market place. Things like bloated muddy mid-bass and nasty and shrill highs. These sound like music and will put a smile on your face. Just buy them, have some fun building something to be proud of, and enjoy some real music. I’m going to buy another set myself. (Yes – I am listening as I type and I am enjoying)

Rated 4 out of 5 by from Think I like them from what I read ?I am going from what I have read in the reviews before I purchase and I am sure I will be very happy with them in the end because I have not purchased anything from Parts Express yet that I did not like but no where in this article does it mention the overall size of these speakers ? thanks ken k

Rated 5 out of 5 by from Easy build even for a novice.I bought the kit based on the reviews. I was not disappointed. It took about 12hours to assemble the speakers. I hooked them up to my mono blocks and they sounded great for the price. I built them for my daughters home theater, front left and right speakers. She loved them. I am now in the process of paintingthem. Great speaker for the price and a blast to build.

Rated 4 out of 5 by from TRI TRIXX Tml Towers "Surprisingly Worthy Upgrade"I bought the speaker build kit after reading many reviews and research ,using ,  3/4 mdf board from Lowes .With some planning and support of Parts express and others who have built these speakers. I would like to thank Curt,Parts Express and all others who posted their experiences while building them.Everything I need to know can be found with  a little searching, from prints, diagrams,parts lists , specs, building,and finishing.The sound from these are a pleasant surprise and a worthy upgrade from mass produced store bought plastic hooties.The footprint is about the same as those tall skinny ones with a big base.8 inches wide.Made mine 43 inches tall with crossover in bottom, and they weigh about 85 lbs.Dimensions 8x14.25x43.Quality sounding, great design and  affordable parts.I am happy with this .Thanks

Rated 5 out of 5 by from Great sound, fun to buildThis was my first attempt at building speakers and, I have to say, I'm impressed!  I started off a few months ago by building a bar with a live-edge, solid plank bar top.  After completing the bar build, the next logical step was to start looking for a stereo setup for music.  After scouring craigslist and eBay for higher-end speakers, I was still music-less in my new bar.  At this point, I decided to look into building myself a set of speakers and, based on the reviews here and on other forums, the TriTrix TL line seemed to fit the bill.  I ordered the speakers and they shipped the same day (with free shipping).  The speaker components arrived at my door just a few days later and, the following weekend, I was well on my way to having these DIY speakers filling my bar with sound.Construction was straight forward after reading the instructions and watching the videos provided by PE.  I bought and used 3 wood clamps during the cabinet build, which would be the minimum amount I would recommend. Cabinet construction was very easy for the most part.  The most difficult part was, after building the majority of the cabinet, setting the last piece (side panel) on top and getting it aligned with the support braces and all other edges.  From my research, don't get carried away with the acousta-stuf polyfill.  I used one bag for both speakers.The thought of building the crossovers was the most intimidating part of the build but, once you understand the schematic and layout, it's pretty straight forward.  If you're new to soldering, like me, practice soldering on scrap wires to hone your skills.  I still haven't mastered tinning but, the crossovers turned out fine, they're just not the prettiest.  I hot glued the crossover components to some 3/4" MDF I had laying around and wood glued it to the top, inside panel of the speaker cabinets.  This kept wire leads short and left ample room for all components once installed.Once I had everything assembled and let the speaker cabinets dry overnight, I hooked them up to my Adcom GFA-555 (200 wpc).  These speakers sound great!  They need some time to break in but, voice reproduction is fantastic.  Highs sound great without being "bright" or harsh.  I could literally listen to these speakers all day.  I did find them lacking in the bass department.  Just today I added my Monitor Audio ASW210 (dual 10" subs) to the mix and it's perfect!  By far the best 2ch setup I've heard and, to think, I built the speakers myself!  I'm really pleased with this setup and my decision to go the DIY route.  By far the best bang for your buck.  I'm already starting to plan my subwoofer build.

performance issue

I have finished my Tritrix speakers and am dissappointed in the sound quality. I have an old pair of Infinity SM speakers and they sound much better. One thing that concerns me is that I need to turn the reciever volume much higher on your speakers to get the same level of sound. Is that indicative of a problem?
Asked by: asg33gty
recheck all wiring, test woofer phase with d-cell bass drivers ,,both,,should move forward when dc is touched to the hot input and ground, go to itunes for 30 sec test tone samples and google some audio free tests this can narrow the problem,, even a speaker may be internally wired backwards and cause audio mayhem .. next check the amp

Does this kit have/need a crossover PCB?

I'm new to speaker kits, though not so new to electronics and soldering, or circuit schematics. I see that this kit includes everything for the crossover but am uncertain how it comes together - do you need to solder this to a crossover PCB, which parts-express seems to sell? Or does it come with its own PCBs, or doesn't need to be on a PCB at all? Thanks in advance for the words of wisdom.
Asked by: charlener
All you need is a piece of wood, or anything non-conductive really. I like to use pegboard, because you can strap the components down by using zipties through the holes, but you can use whatever you wantOn the product's page, look under Product Videos (near the top). One of them shows the assembly of the crossover. You can also check out the Techtalk forum. You'll see lots of builds that show assembled crossovers

where exactly does the crossover mount to inside the enclosures?

please describe in general / generic terms and include a picture or diagram if possible. thanks.
Asked by: JJPP
There are no restrictions to where the crossover needs to be mounted. Most customers place them in the bottom of the cabinet near the terminus.For more information, refer to this webpage:http://www.parts-express.com/projectshowcase/indexn.cfm?project=Tritrix

How badly will I affect the sound quality if these are modified slightly/installed in an entertainment center?

I have a large entertainment center and would love to put a couple of these inside on either side of the tv.My questions are two-fold:1) Does the TL design require the speakers to be set away from side walls or would it be ok for them to be in what is essentially a large cabinet with a TV in between?2) I have exactly 35.5" of vertical clearance inside the entertainment center and, according to the drawings, these are exactly 36" tall. Would I be causing irreversible damage to the sound quality of the design if I cheated 1" out of the bottom of the cabinet?
Asked by: osu32
the tri trix uses the out of phase back wave of the woofers to invert in phase with a horn/labyrinth backside to revert the bass wave below 1oo hz into the room in phase the effect of shrinking the cabinet is changing the low end response slightly , the tri trix is a free standing system and you may try other configurations with your cabinet with better results, you have plenty of room for other designs in the center, look at some of the projects on the DIY page, adjust your ideas ,maybe a separate sub or 4 , 5 in clearance 2 ohmers and a good x'over with tweeter. a sealed cabinet that fits your shelf would perform better and you would have to decorate only the front of the system,Many options with this much space!

Bass volume?

I live in an apartment and don't want to irritate my neighbors. If I have these at a reasonable volume, will the bass be loud enough to cause issues?
Asked by: MinskyBA
the bass falls off slowly around 100hz but still has good response around 40hz. at low volume i think these would be fine. just be warned they will get LOUD :-). i use a ta2020 Tamp (15Wx2) and they sound great.

Any options for doing a bi-wireable build?

I'd love to be able able to "passively" biwire these. Any options for that? Keeping in mind that I'm an absolute novice and would have no idea how to change the crossover design or whatever on my own.
Asked by: wes in va
If you have a good amp to begin with, there would be little benefit to bi-wiring this speaker. The benefit in "bi-amping" is that each amp only handles a specific frequency range optimizing its performance - which requires an electronic crossover. This speaker could, however, be converted to bi-wire. You would need a different terminal setup for the cabinet back, and yes, you would need to know how to work with the crossover components to do the job. It's not terribly
