Alright so after searching for the right speakers for my new setup I decided I should try building my own. I've never done a DIY speaker project but I figure if I can build an arcade cabinet I should be able to handle speakers.

I did some shopping on Parts Express and drew up a shopping list for a 5 (maybe even 7) channel setup. The speakers would be 2-way all around with dual woofers for the front and center channels. The whole setup would most likely be powered by an Onkyo AVR in the 125-135W range (717, 809, etc) depending on what's readily available on the market once I'm ready to hook it up.

Having never done this before, I'm hoping I can get some advice on what parts to use. Here is what I came up with already with my budget, if these aren't a good combination please let me know. smile.gif

Fronts: ~4' floorstanding towers

Center:
  • Same components as Fronts, just in horizontal config

Rears: Bookshelves

off the shelf crossovers like that aren't going to make speakers that sound that good, you should find one that is specifically designed. Check out diysoundgroup.com they have a lot of great speakers you can build with specifically designed crossovers.

any speaker from this page http://www.diysoundgroup.com/waveguide-speaker-kits/fusion-series-kits.html would absolutely blow those parts you picked out of the water.

Those kits are quite a bit outside of my budget range though. I'm hoping to keep the BoM for components under $500 (not including wood, wire, paint, etc. as I have a lot of that on hand already). I'm already thinking a 3500 Hz crossover might be too high for that pairing. The max on the woofer is 4000 Hz and the tweeter goes down to 1300.

I'd cross that over at 2500 or so, but I certainly wouldn't use that premade XO.

How about some other designs that use less expensive parts.

Google "Iron Driver Best Sound TechTalk"

They should be close to your budget and there's a dual woofer and single woofer version.

Actually, it looks like they practically sell kits for that exact setup already, with crossover components that just need to be assembled. I think I'll pick up a BR-1 components kit (http://www.parts-express.com/pe/showdetl.cfm?partnumber=300-643) and a TriTrix MTM component kit (http://www.parts-express.com/pe/showdetl.cfm?partnumber=300-702) and build my own enclosures for them.

I'd look up Swopes and Overnight Sensations... Both have MT, MTM, and Center channel designs. But, they both should be paired with subwoofers. Swopes also have a 3-way tower as well. Kits are available on Meniscus audio.
