When building the TriTrix speaker enclosure what are the dimensions of the 45's in the bottom corners?? The building schematic include everything else but does not include the information for the 45's.
The length of the 45's are 6" at the longest, from "point to point" on the midered edges.

What is approximate resistance as measured from terminal posts of complete tower? I know this has been asked many time, but what is the ideal minimum amplifier RMS at aforementioned mystery resistance approximation? I'm considering Dayton Audio APA150.
The lowest the impedance dips on these speakers is about 7 ohms, so any standard 8 ohm amplifier will have no trouble powering these. An APA150 will be a great match.

Im a beginner to carpentry. I want these puppies to look beautiful! Can I stain this wood or upgrade it to better wood somehow?Thanks! You guys rock!-Chris
These cabinets are made from MDF which is not stainable. You will have to cover these in a real wood veneer in order to stain them properly.

construction and installation process
After reading a few forums, I'm still a little confused on the best process for putting these speakers together.I would guess that you would build most of the cabinet (leave one side off) and install the x-over and cabling, running the cabling out of the driver holes. Then finish the final side of the cabinet, sand, prime, paint, etc. Stuff in the....stuffing, and then connect and install the drivers.I've seen some projects where the entire cabinet is finished before adding any of the components or cabling - but don't see how that could be done with this kit.Any help or advice is appreciated!!
These can be constructed in either fashion that is easiest for you, there is not right or wrong. Since the polyfil needs to be evenly distributed throughout the line, leaving one side open may be the easiest method.

Anything else needed
I'm not familiar with any of this, I was wondering is anything required other than what is given in this pack to have a fonctionnal Speaker System?
All you need is amplification and whatever finishing option you prefer. This kit contains everything required to build a pair of speakers.

These sound too bright - will they mellow with break in ?
I just completed my triTrix TL s and am now listening to them next to my 1983 vintage KEF 103.2 reference monitors (a 2-way sealed design). The KEF's cost $800 a pair in 1983 so maybe it is not a fair comparison, but the Tritrix's sound thin and harsh by comparison. Ton'y Rice (Bluegrass) vocals sound thin and nasal on the Tritrix. Will this change with playing time ? Any suggestions are appreciated. Thanks.
I am answering this myself. When I compared them to the KEFs they were backed up within an inch of the Wall. I moved them to the other room where they stand about 5 inches from the wall behind them. It made all the difference. They sound full and consistent with the favorable reviews. I am pleased

Would the 8ohm version of the woofer (DC130BS-8) in parallel work with this enclosure? The specs are somewhat different between the two versions.
No - the crossover is designed for the 4 ohm woofers.

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.
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

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.
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

noob here...Looking for a good amp to pair up with these speakers.It'll be used mostly for music/HT duties and hooked up to PC as well as an mp3 player.Additionally I have a set of senheiser HD590s that I would love to be able to hook up to the amp.My technical audio knowledge is a bit lacking to put it mildly.I was checking out the Dayton Audio DTA-100a Class-T Digital Mini Amplifier 50 WPC. (because frankly it has a lot of good reviews).I have no idea if it's underpowered etc.If it's not suitable, any specific suggestions and/or what specs should I be looking for to be able to drive these speakers well and my above needs. (I definitely like the idea of a small portable amp as my space is quite small....and would be great to be able to travel with this setup)Thanks!(Also, anything else I should order along with this build? Supplies or Tools wise. I do however have plenty of power tools)
That's a lot of questions. 50WPC is too low if you are going to use this speaker full range. I would not use an amp under 100 WPC at 8 ohms 20 - 20khz. Also, Class T and other newer topologies are nice for certain projects - but for music and home theater (more audiophile performance), and you want to get a more classic design - like a class AB amplifier. There are many new brands, and lots of used amps on the market on auction sites. I can't really go into detail on the PE answer area. You are building a potentially great spaker and will enjoy them a lot. From PE - the AudioSource AMP210 is a great amp - take a look at them on the site...

How well will these work with a JVC SR S300 Amplifier (1987)
I bought a couple of the Dayton B652 speakers and they sound pretty good with the above amp which has 50 watts RMS (each channel) into 8 ohms. The amplifier is rated from 20Hz to 20 kHz at no more than .1 % Harmonic Distortion. Will the TriTrix Kit Speakers sound a lot better with this amp, or can you recommend another pair on your site that are reasonably priced?
The interpretation of audio is completely subject to the opinion of the listener, so honestly, no one but you can say what will sound "better" or "worse" to you. Having said that, I think it is safe to say that most listeners would perceive the TriTrix kit as having a better overall sound quality. If you like the B652s, odds are that you'll love the TriTrix (and you'll also enjoy the satisfaction of having built them yourself, if you're into that kind of thing at all).

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?
Speaker efficiency is not a "problem". Some speakers are more efficient than others. If you listen to both speakers at the same relative level - listen to the bass extension, bass detail, definition in the midbass, transition through the vocal range, smoothness - accuracy - and speed / attack time of the highs, and extension past the audible region. That would be how you differentiate quality between your old and this new speaker. Yes, drivers do sound different. Make sure to test the old and new with the same program material and use male and female vocals as well as classic, jazz and rock music if you like minimally. These are the ways reviewers quantify a speakers ability to reproduce music accurately. Once again, efficiency is not a sign of quality or a problem.

What is the RMS wattage spec?
For some reason, I do not see this specification listed anywhere on the product page. How many watts can I safely feed to each speaker? I would like to pair these to my Pioneer VSX-60 Elite receiver, which puts out 90 watts/channel.
If you take a look at the drivers listed in the kit, you will see that each woofer is rated at 30 watts, therefore the speaker would have a nominal rating of 60 watts RMS.

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?
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.

Is there a "Standard" grill cover for this kit?
We do not carry a grill for this (or any other specific) product, however, we do have supplies you could use to fashion your own grills. I've linked some parts below for your reference.

I'd like more precise info about where to put the polyfill. Inside front? Inside back? On the slanty piece?
The reason I chose to build these is that the info is precise, plus there are videos. Is the placement of the polyfill a black art, or are there specific places it should go; if so, where? I cut my boxes out of mdf and they're glued-up and ready to go--hope to do crossovers and hear some sound next.
you should loosely stuff the chamber behind the drivers.

The sound is flat.
After completing the kit, I tested it and the sound is flat. No bass. What did I do wrong? I assembled the kit and crossover as instructed on the diagram and video. Is there a pre-assembled crossover for the tri-trix? Please help.
My first idea is that you might have crossed the polarities on the woofers, they'd basically cancel each other out if wired backwards. Beyond that, there's not much I can do to troubleshoot without being able to check every polarity and every connection with an ohm meter. If you have a tone generator, you might be able to gain more insight into exactly what is going on. Also, you can check each woofer with a D-cell battery to see if it is working normally, or wire it directly to the amp and run it at modest volume.

Tritrix + Dayton DTA-1 amp
How would this speaker kit pair with the Dayton DTA-1 amp? Or does it need more power to drive the pair?
DTA-1 would be enough to get them going, loud enough to enjoy music or video-audio perhaps. But you'll want more puup if your trying to fill a room with clean-sound.

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?
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!

Good speaker upgrade
I have been reading reviews and build logs on this setup and everything and i think im gonna give it a shot.. I just wanted to know if there are better speakers to use besides the ones included
This was a very well thought out and set up design for the drivers in the kit. Unless you are wanting to go down a totally different road and build another customer speaker, I doubt you will find anything that is really better. Opinions always vary and there are two or three other drivers that would definitely work in the enclosure, but they would require extensive modification to the crossover to make them sound right. I would say go for it just like it is. I can't imagine any dissapointments coming your way. I have heard several pairs of these now and am really impressed with how well the design came together. Hats off to Curt for making it available.Are there better speakers out there? Sure but not with this level of finish and easy build and already put together for you. IMHO this is one of the best "kits" I have ever seen. For $259 you won't find anything close on the market that's for certain.

What is the impeadance of the speakers? 4, 8 or ??? ohms
Relates to the TRITRIX MTH speaker package
Each finished TriTrix speaker will present an 8 ohm load to your amplifier.

What is the measured sensitivity of this speaker?
Unfortunately, we do not have a specification for the sensitivity of the completed kit. According to the designer, the modeled maximum sensitivity is 104dB.

Why is there no matching Center Channel kit for this on Parts-Express?
I would like to have a matching TriTrix Center Channel kit with this. Why doesn't Parts-Express offer one?
Parts express has a wide variety of consumers from audiophile two channel to home theater 5-7 channel. Most center channel speakers are crossed over at either 80 or 120 hertz, you don't need a big center channel to handle that range, most use a small center channel speaker. thanks Ralph

Where does polyfill go in a Tritrix TL box?
What is the proper positioning (stapling?) of the poly filling included in this kit? Thanks
Typically, stapling, gluing, or otherwise securing polyfill to a cabinet is not necessary. Simply fluff the material up manually, and insert it behind the speakers. Start with the top woofer cutout, and work your way down the cabinet from there.

Would the cabinet benefit from spikes?
Whether a speaker enclosure will benefit from spikes or rubber feet depends entirely on the surface it will be sitting on. If it is a hardwood or laminate floor, small rubber feet work very well. If it is a carpeted floor, the spikes are the best because they penetrate the carpeting and sit on the underlayment below, coupling them to the floor. This has been known to improve clarity and stereo imaging.

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.
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
