TriTrix crossover help

[joemomma]

Hey guys - first post. Recently completed a build on a Dayton 15" Reference with the PE 500 plate amp to "compliment" the 12" JBL I have in my main TV room. Let's just say there really isn't any point in the 12" JBL anymore. Anyway, I've been thinking I might like to try and build some tritrix to replace my Boston front L/R, and the matching Boston center. The TT seem like a good way to go for all three. My question is concerning the crossover - I watched the video, looked at the schematic, etc but just don't seem to "get it" as far as soldering/connections. It's been years since I had electronics in college. Is there a "better" video/step-by-step instructions for crossover assembly? Maybe it will make more sense once I have the pieces in front of me.
I was thinking about making the "sealed" version for all three, is this the best way to go? I can make the enclosures myself.

The tritrix crossover is a very simple 5 element design. I'm sure you can do it. If you go to www.speakerdesignworks.com and go to the third page of the tritrix writeup, there is a layout showing how to connect the components. If you don't understand that drawing, you should seek help.

The sealed tritrix are the smallest and easiest to make. They would go well with a subwoofer which you already have.

Stay with the TL design, they will give you some really great bass over a sealed version! As Mr Campbell stated in his design, the TL means you can also play them louder without obvious distortion setting in over a ported or sealed design for your mains! Use a ported design for a center channel.

Thre are plenty of posts here on the x-over build with pic's! Just do a tri Trix search or others may even do some posts for you. Lucnhmoney is the one to contact here for good info.....

I will make a lot more sense once you have the crossover components on hand. Buy a small spool of 14-16 guage zip cord (cheap home AC extension) to use for wiring up the crossover and connecting to the drivers inside the box. There are a zillion variations of mounting the components to a board. I prefer to hot glue and zip tie them to a piece of perforated masonite, then (and only then) twist the wires together and solder the connections.

HTH,

Wow, thanks for the responses guys. I'll check that link djg - hopefully it will make perfect sense. I'm fairly handy, so hopefully I can make it work.

Next question - so for the L/R, the complete TL kit is the way to go. For the center as a ported design, what has to be changed? Are there specs for enclosure size/ports/etc available? I'll try to do a search for them and see what I can find.

Go to You Tube as P.E. has a how to video .......Its awesome watch that and you can't screw it up......Good Luck.
You won't be disappointed with the TriTrix design.

For the TriTrix variations, check out Curt's website (http://www.speakerdesignworks.com/index_page_2.html). He has both all the MTM (http://www.speakerdesignworks.com/Tritrix_pg_1.html) versions as well at the MT's (http://www.speakerdesignworks.com/TritrixMT_pg_1.html) fully documented.

Thanks guys, just checked Curt's website. There is a page there with a detailed description of what a "node" is considered, etc. Makes much more sense now. In fact, I think it is the TT crossover that he uses as the model. That has really helped.

Oh - one more thing. Seems like I read that these were 6 ohm speakers....will this be an issue with modern receivers? I'm using an Onkyo TX-SR574. Is there a way to make them 8 ohm? My rears are 8 ohms - any issue mixing impedences?

[curt_c]

Fear not! The TriTrix MTM's are 8 ohm speakers.
