Getting TriTrix components - making my own cabs

I bought the TriTrix component kit from Parts Express and plan on building the TL Version of the cabinets myself. This is my first DIY speaker build.

There was an old website that seems to have been gone by the wayside now and only available from Wayback Machine. I can't post URLs yet, so I've attached the output from that page to this post.

There are plans for the cabinets with a little tweak from the original kit plans if I bought the knockdown parts from Parts Express.
I'm wondering if the minor changes at the website above (speaker placement is the bigger change I think) - will make cost me anything in sound quality. He changes the width of the front panel to make it wider, but the volume of the cabinet isn't supposed to change.

I'll be using this with an Akai AA-R42 stereo and Dual 1019 turntable.

Any thoughts on this?

Not much.
I sent them this:

Hello,

I just bought the TriTrix TL component kit. I plan on building the
cabinets myself.

I have a few questions.

1. Will the parts/component kit also include the plans for building the
cabinet?
2. I found an alternate cabinet build for these speakers online, and the
user seems to think he's improved the design a bit. I can see where he's
coming from, but question whether it'll affect the sound too much.

Here's the link:
My link to the other website - which is the 1st document I attached above (I still can't post URLs since I'm new here)

He changed the box design a bit (for strength and finishing with
veneer?) - and moved the speakers a bit to make it easier to veneer the
cabinet.

Do you think this will be acceptable to build with his plans instead of
the original?

Thanks. I'm looking forward to building these speakers.




They responded with:
Hello,


I am sorry, there is not a build plan for the cabinets, but the link below will provide the crossover layout.

without doing all the math,

the dimensional swaps were to strengthen the cab and baffle,
internal panels may need some adjusment wrt to the 1/2" changes

everything else appears to be in good order

his driver spacing suggestions are likely to be minuscule wrt to significant changes

you will have far greater challenges / "dialing in " issues with placement, the room, etc.

and that vintage Akai, bare bones - with what, a treble and bass tone control set-up.

build the speakers well and enjoy them- it's supposed to be fun
but if you get the chance to drag them over to someone else's set-up, go for it and test things out

comparison is good

I started with this kit from PE as my first attempt at DIY (AIY) and was very happy with the sound they produced. It was the first TL I had spent much time listening to and was shocked at the performance, especially when you think about the $ spent. High value speaker to say the least.
As said previously, assembly them and start enjoying the sound.

I have the speakers together. I'm not a woodworker and really don't like working with wood at all. The results reflect that, but they are built and work great. All that's left is to put some cross-braces or dowels in to support the batting inside and glue/caulk/screw the last side panel on. Well, that and use some bondo to fix the sub-par construction and then veneer the outside.

I'm glad I made these speakers. I'm not an audiophile, but these speakers do really sound great. They have more bass than I expected. Enough to the point that I don't think any sub-woofer is needed.

The homemade router circle jig worked pretty well. It was sort of hit-or-miss and guess as I did it. It went much better after I bought some new/sharp router bits that didn't just burn the wood.

I can't show pictures because I don't have enough posts on the forum yet.

I'm sorry, but I don't have a clue what REQ, AVR, HPF or REW mean.

I'm trying the pictures again.

You'll notice in a couple of the pictures, that the tweeters were really out towards the edge of the cabinet. I filled that in with bondo and re-cut them closer to being in line with the woofers. I have to patch up the rest of the dings and screw holes with bondo now. And finish with a veneer of some sort.

I'm running a simple vintage Akai receiver with only bass/treble adjustments for now. I think my next purchase will be a WiFi/Bluetooth receiver to input audio from my phone or PC into the receiver. And take my Dual 1019 turntable in to get adjusted before playing vinyl. Then maybe down the road futz with the EQ/sound quality.

I also see one of the Parts-Express portable battery powered bluetooth speakers in my future to take out on the back patio or use in the garage.

Thanks everyone for the added confidence helping me in building the speakers. I'll post more pictures as I keep working on the speakers (but it may be a while before they're actually veneered)
