TriTrix MTM TL Speaker Components And Cabinet Kit Pair

The TriTrix MTM Transmission Line Speaker Kit includes all the components you need to build a pair of the renowned TriTrix MTM speakers. Nearly $400 worth of components and cabinets have been discounted to almost HALF of the original combined price to save you money and get you started in speaker buildling. The knock-down TriTrix MTM transmission line (TL) cabinets save you time and money.

This kit's precision CNC cuts offer accuracy comparable to the craftsmanship of a master woodworker, maybe even better! 3/4" MDF construction ensures maximally damped enclosures to prevent annoying resonances that color the sound. Cabinets ship unassembled, but are simple, quick, and easy to put together. The TriTrix knock-down cabinet pair and the TriTrix component kit have been tremendously popular with Parts Express customers like you. Buy these two great kits bundled together and save!

Rated 5 out of 5 by from Well worth the cost and effort.I'll be honest. I'm no cabinet maker or an electronics expert. This being my background, I probably made every mistake you could make building these speakers. Thus, the speaker cabinets look like an amateur built them. Don't look at them in a lighted area. I also had to replace electronic components due to my lack of ability and confusion. Therefore, I can't speak to the ease it take to build the speakers. I also can't speak to the beauty of the pair (or my pair). However, despite the added expense, lack of looks and frustration, I would build these speakers again.I haven't had this interest in music since I bought my old B&W 604 speakers. These speakers are clear, clean and do play loud. Cleaner sound always seem to be lower in volume until you stop listening and realize just how loud you were playing your music. Even with my cost increase, you will not find a better sounding speaker. To the naysayers regarding price point speaker comparisons, to really hear a significant improvement in the sound of the a really good speaker, you do have to triple the price.These speakers are definitely not a B&W 600 series floor standing speaker, but for my money there is no embarrassment putting these speakers in the same room (Yes, I have heard the newest 600 series line).My only, recommendation is to ask plenty of question of sales and support staff and persons who have cabinet making and electrical experience to avoid my follies.

Rated 5 out of 5 by from Can't really complain about anything here...Was going to drop some real money on a pair of speakers when a buddy talked me in to building a pair. Definitely think you'd have to spend a lot more to get something on par in a retail store....like in the $1,000 to $1,500 range? Guests can't believe I built something that sounds so good. The low end could use some eq-ING or better placement than I have them in. Finishing has been a challenge using the veneer I selected (red wood burl - lesson: use a paper backed veneer).But for about $250, you can't go wrong here.

Rated 5 out of 5 by from Exceeded Expectations!!I just got done with final assembly on my first Tritrix build and I am so excited with how they turned out. The kit was very easy to assemble and had I not changed the baffle and the bottom of the cabinet to fit the look I was going for, then I could have finished assembling the kit within a couple hours. I am an experienced woodworker, but even a first time builder should have no problem assembling these guys. After cabinet assembly came the crossover build which was also not too much of a problem once I had my component layout designed, but it would definitely be nice if there were a PCB for the tritrix that came with the kit to take the guesswork out of the crossover build and to give the whole kit a more professional look. (Hint hint Parts Express). After the speakers were functional I took them to my media room and was blown away with the sound that came out of them, even before they were really broken in. In my opinion they blow away anything that you could buy at the big name stores up to the $600.00 range and is comparable to some that are much more expensive. The only thing I regret about this build is that I didn't build them for myself! Instead, a buddy of mine will have these in his living room as a constant reminder to me that I should trust the reviews and just build them instead of telling a friend to front the money and I won't charge him labor on a gamble that they may sound good at the end of the build. Well I got the short end of that deal and he got a phenomenal set of speakers! I highly recommend these to anyone whether they are novice or advanced, because they are all around a great set of speakers!

Rated 5 out of 5 by from Great Product!I bought the TriTrix a couple months ago and have loved them ever since. I was extremely excited to put these together and this was my first major speaker project. With the help of the Parts Express assembly videos, putting these together was a breeze! (as you as you can solder)I ordered these based off a friends recommendation and listening to his pair. These speakers sound phenomenal for the price and are a great introduction to speaker building.

Rated 5 out of 5 by from Fantastic Value, Awesome SoundWow... After many hours of searching forums on the net for a DIY project for my living room HT mains, I finally pulled the trigger on this kit. If you're on the fence between the aviatrix and these like I was, I can say I'm more than happy with the tritrix choice made.I built the TL versions for L/R fronts, and the sealed version for CC, and these things absolutely sound stunning. A huge quantum leap above typical HT-in-a-box speakers. I mean, I'm literally blown away. I have these connected to an older Onkyo 100w per channel receiver, and they will play very loud and cleanly. Set in a medium size 15'x22' living room, my entire house jams, way louder (and I do mean WAY WAY louder) than any normal listening levels, and they sound clear as a bell. In stereo, the imaging is amazing, you can "see" with your ears where the voice and instruments are placed on the stage.I've listened to some expensive speakers over the years, and these sound to me better than many store speakers at triple the price. Maybe it's because I built them that I'm so amazed, but I can honestly say, they sound far better than what I was expecting.I listen to rock, electronic, pop, dubstep, jazz, adult contempory, and country. And it sounds excellent with them all. Bluray movies sound great in surround too. The sealed CC plays voices very clearly, action scenes sound amazing. *If you like heavier bass, you will want to add a subwoofer* I do use a sub for 5.1 LFE and music, maybe not necessary for some listeners with music.The knock down cabinets are well made, and assemble straight and true. I modified the cabinets some, added black lacquered baffles and bases with billet feet, and covered in Wilsonart HPL.GO AHEAD AND BUY THEM!

TriTrix MTM TL Speaker Components And Cabinet Kit Pair

what gauge wire can one use  to wire  the speakers up internally?.  I  have  a  bunch  of  16  & 18  guage  wire  (  stranded )  that  I  would like  to  use.

Asked by: deebee
You will not need anything bigger than 18 gauge for the internals on these speakers.

What is the Frequency Response of this speaker project?

Asked by: JuneBug
This system has a frequency response of ~50-20,000 Hz.
Answered by: MattP
Date published: 2014-08-06

OK. Since there is no ground wire (or speaker internal wire in a kit that indicated everything was included), what gage and other requirements should I look for in buying ground wire for these speakers?

Asked by: kmpurcell
Standard speaker wire is recommended for an application like this. The gauge is not very important, something like 18 or even 20 gauge will be fine for crossover wiring.

Hi, I'm interested in getting the TriTix. I thought I had read somewhere that your kits are now coming with assembled X-overs. Is this true or will I still need to assemble my own? Thanks!

Asked by: marke67
Unfortunately the Tritrix is only available with a kit crossover and does not come assembled.

I have read the following regarding stuffing. Manually insert it behind the speakers. Start with the top woofer cutout, and work your way down the cabinet from there. Are we talking just the front or the entire chamber front, back, sides, top?

Asked by: kmpurcell
The amount of stuffing in this speaker will determine the amount of bass you will get. Usually you stuff the whole front of the cabinet all the way to the bottom, using one bag for each fluffed up like a pillow. If the bass seems a bit too lean, remove some. If it sounds a bit muddy, try moving the stuffing up tighter around the backs of the woofers.

Please tell me what the specs are - Freq response, Impedance,Sensitivity and Recommended Power min, RMS, Max.

Asked by: Kmpurcell
These will play from 50-20,000 Hz, have an 8 ohm impedance and the power handling is 60 watts RMS and 120 watts Max.
