Parts Express TriTrix MTM TL Speaker Components And Cabinet Kit Pair
TriTrix MTM TL Speaker Components And Cabinet Kit Pair is rated 4.7273 out of 5 by 55.
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.

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.

do I need to by anything extra to be able to connect the speakers with an aux. cord for my iPod?

Asked by: Caitlin
Yes, these will require an amplifier between them and the source. Anything that is 50-75 watts RMS per channel will be enough to power these.

Should the inside of the speaker cabinet be painted.  Since the outside will be painted, it has always been a general recommendation to always paint both sides of MDF so it does not warp.  Is this necessary fo the speaker cabinets?

Asked by: DBY49ers
MDF is pretty stable and with the way it is built and braced there is not really any need to paint the inside for any structural reasons. Some people will paint the lower portion though since you can see into the cabinet through the TL outlet
