Parts Express TriTrix MTM TL Speaker Components And Cabinet Kit Pair is rated 4.678 out of 5 by 59.
Rated 5 out of 5 by from Nice sound! Not too easy for a newby though.First off....I am a complete amateur when it comes to speakers. This was my first time to do a project like this with no wiring or wood working experience. My suggestion.....you can't have too many wood clamps....I had four and needed more. The instructions are poor but the online how to videos are a great help. The finished product....I'm happy and the sound is great for the money! I almost want to buy another set just to do a better job the second time around.

Rated 5 out of 5 by from Even better than expected.I got these after reading the many glowing reviews on them. I've never built a speaker before and I figured that it would be fun. It was a very straight forward process thanks to some easy to find crossover schematics (thank you Google). The cabinets went together very easily and the crossovers were a snap to put together. As for the sound, I don't think it can be overstated how good these speakers are. Especially when you consider the price. They play quite clean and can get very loud. As others have said they put out a decent amount of bass, but adding a subwoofer really helps round out the lower end. I have these running in stereo mode on a Denon AV-890 receiver, teamed with a Bic F-12 subwoofer for anyone who is interested. Could not be happier with the F-12 as well. Going to have to get started on the Tritrix center channel now. A kit for that would be nice as well....hint hint Parts Express.

Rated 5 out of 5 by from Excellent performance and valueFinished building these a few days ago and am very pleased with how these sound. I'll certainly be psyching out the stuffing as they are broken-in, but with light stuffing to start they sound beautiful.Bass is present and accurate, though I hope it will become a little more pronounced as time goes on. Midrange is prominent though not "squawky" or harsh. Upper end is very nice and smooth and airy. I should say I have EQ on my amplifier set flat. Tweaking speakers requires getting them as "right" as you can with no EQ, then touching-up with the controls.Building the cabinets posed no problems. Lots of glue and clamps. I used the screws for holding while the glue set, then removed them and filled the holes (they serve no purpose after that - the glue is stronger than the screws).I sprayed sanding sealer on the end "grain" edges and the filled screw holes. Then, after a light sanding, I brushed de-waxed shellac on those same areas. Then another light sanding. Sealed all that right up! After a good rolled on primer, they were sprayed flat-black, then 2 coats of clear matte acrylic.A simple oak panel on the lower half of the front (finished natural), and I now have a couple of stunning speakers!All in all a wonderful value and, so-far, excellent performing speaker system for those who like to build and tweak things. Looking forward to years of listening (and visual) pleasure!

Rated 4 out of 5 by from Great Beginning ProjectThe TriTrix speaker cabinet project is a very good undertaking for a beginner.The Positive:When assembled, these speakers stand 36" tall. I'd classify these as a smaller to medium frame floor standing speaker. When assembled properly, you'll have great top end response and satisfactory bottom end response (good considering the 5.25" speakers used). When paired with a decent sub-woofer, these speakers can and will shine as main left and right speakers in a home theater setup. These speakers will do very well in a small to medium sized living room space or condominium/townhouse setup.The Negative:What you need to look out for when assembling this kit is the weaker screws that are supplied. You should absolutely use an impact driver type of tool when assembling the cabinets. The screws have a tendency to strip and break if you use to high of a torque setting on your impact driver. The screws also have a tendency to break being lesser quality when using an impact driver. Attempting to manually screw the project together, even with pilot holes, will be a forearm burning challenge to say the least.Listening Experience:These TriTrix speakers, as mentioned above, have a good response in the mid to high end. Watching Godzilla-2014, These speakers shine with the environmental effects sounds from the glass shattering to the orchestral soundtrack playing throughout the entire movie. The midrange response seems well balanced, not muffled or sounding like a tin-cup. Godzilla's monster breath windup and subsequent orchestral sound is done justice by these speakers.It should be noted that I'm using a Marantz SR7002 "pre-outed" to a Nikko Alpha II amplifier that pushes these TriTrix speakers with no issue whatsoever. I haven't had the cajones to take the Marantz past -10 dB on any of my speakers. With that being said, these TriTrix towers held their own under the abuse at that level.Keeping this realistic, what the TriTrix speakers lack is the "presence" of large mains. Some might initially say, "No duh!" and I'd agree. When considering these speakers you need to take the height of the speakers and the space you're working in. I have another set of mains that are relatively unknown to most but are a spectacular set, especially for an estate sale find in my case. I used a pair of late 80's Symdex Epsilon three way towers (10", 7", and 1" setup). The TriTrix had a tighter and more crisp top end, whereas the Epsilons had a much more authoritative mid and bottom end. Again, cue the "duh!" comments. The sheer size and 49" height of the Epsilons allowed it the room filling authority that I cannot handle in my current room setup. First world problems! This goes to my earlier comment that the TriTrix speakers are an excellent choice for a small to medium sized room that wants big sound.My conclusion on the TriTrix speakers are that you should give it a go. Why not? Especially given the excellent price point, learning opportunity, and great sound achieved when the project finishes. Sit and think about it for a second, because that's all it should take. You'll get better sound from other speakers...but at least three times the price point...This should be a no-brainer for you guys. Go buy the kit.

I do a lot of vintage speaker refurb, but I gotta tell ya I've no patience for installing veneer. :-) How well do these accept sprayed semi gloss paint for a final finish?

Asked by: ProPerDoper
Don't go the veneer route if you don't have time. As for paint you will need to prime it with a good primer maybe two coats of primer to give the paint a chance to stand on it's own.

I'm a total beginner with no supplies. What additional supplies will I need for this? wiring, glue, etc....

Asked by: Jbird75
The easiest way to construct these cabinets is with standard wood glue like Titebond II and clamps of your choice. If you do not want to wait for each panel to dry, you can use small screws or brad nails from a nail gun along with the use of glue. Standard speaker wire is all that is required for internal wiring, anything that is 16 or 18 gauge will work fine for this. The crossover assembly can be done on a piece of cardboard with the components hot glued in place and simply soldered together. The cabinet finish will be up to you.

Can you replace the speaker with a higher quality speaker like bose or beats speakers but use the parts still included?

Asked by: Rikkigman
Unfortunately no. This cabinet and crossover is designed around the drivers used which are very good quality drivers. Changing these will change the sound and probably for the worst.

I purchased a Tri Trix MTM TL kit and want to set my receiver to the proper ohms. Your specs state the input rating is 4 ohms, but in your "questions" section MattP says (18 days ago) these speakers have an 8 ohm load. Do I set my receiver at 4 or 8?

Asked by: dby49ers
These are an 8 ohm speaker, our site is not correct and I will have this fixed. These use two 4 ohm woofers in series for an 8 ohm overall load, and when I look at the impedance graph for the design it never dips below about 6.5-7 ohms which is typical of an 8 ohm speaker.
Answered by: MattP
Date published: 2015-01-09

Is this system an overall 4 ohm impedance system?

Asked by: Jonzman
No, this system uses two 4 ohm woofers wired in series for an overall load of 8 ohms.
