Eric?
Canadian 8" & Coral tweeter?
How do they sound? What are you using for amps & source?
Tell us more about the process.

Yes, I'm Eric. I bought the drivers you mentioned. To me, they sound better than I could have hoped for the money I spent. The treble is clear but not harsh, possibly a bit mellow. The mids are the best part - voice and lyric distinguishability is excellent! The bass is decent but somewhat lean. I haven't installed a baffle-step correction yet, may do so soon. I've got an older 40 watt Sony T-F4A amp, with a Dual 701 and a Panasonic DVD player as the sources. They're extremely sensitive - at a reasonable level, the 8 ohm VU meters on the Sony sit at a nominal .01 watt level with peaks rising to .1 watts.
The boxes were built using .75" MDF, carpenter's glue and an air nailer to hold it together while the glue dried. I expoxied in some tee-nuts for the drivers. I used contact cement in a spray can to attach the foam on the inside. This stuff comes out like spider web and won't soak into the open-cell foam; it worked excellently. The foam comes from Walmart

-it's meant for use as a sleeping pad. The veneer is an adhesive-backed vinyl laminate from PartsExpress. It works well, but you need a steady hand and a sharp single-bladed razor blade to trim it neatly.

Don't you think that the front panel is a bit thin? It may lead to low end problems when you want to add a subwoofer.

I hope they're not too thin - the whole thing is .75" MDF and the completed speakers are not light:cool:

IME those L-Pad attenuators are BAD news sonically
[/B][/QUOTE]
I put these in here because I had to finish these in one day (tight time schedule) and had no idea how sensitive the different drivers were. It turns out that so far I've left the L-pad at zero attenuation said:
What have you built before?
(BTW: this one should easily qualify as a Frugal-phile(tm) speaker)
dave
I've built subwoofers and installed stereos for my friends' cars, constructed a few headphone amplifiers, and built remote-control airplanes in the past. Speaking of frugal, now I need an easily built low-power amp - something <5 watts, Class A tube or MOSFET.
