I don't see a picture with the grill off. How do you know?

Use a bit less glue, and use blue painter's tape around the edges that aren't being worked. You don't need a huge amount of glue, at least not with the Titebond Cold Press.

Hi,
I hope you don't mind me chime-ing in here but I learned a lot.
I love the crossover integration and the mix of woofer / mid slopes. thanks heaps Paul. cheers, Jack

The process takes more time than contact cement, but I don't think is any harder ... and cold press is a better bond than contact cement.

Re: about the shape...
No, no! We likes the angles. Just another set of stacked boxes otherwise.:p
Originally posted by Paul Carmody View PostIn case anyone was wondering, the angled cabinets in this design are purely cosmetic. One could achieve the exact same-sounding speaker using rectangular enclosures, just as long as the interior volume of the cabinets is the same.

Ooooo, I like these. I have no reason to build a pair, but I really kind of what to. I guess I could put them in the living room. Or in the music room and move the music speakers to the living room, heh.
Actually I'll probably just push to get somebody I know to build a pair o have me help them build a pair so I can see and hear them. Either way, I like. Are these by chance what you're bringing to Iowa? *excited*

Re: Crossovers n' measurements
First off, I have a name for these monsters! I call them Tarkus. For those uninitiated in prog rock, it's the name of an epic song by Emerson, Lake, and Palmer (which sounds quite good on these :D). Tarkus is a half-armadillo, half-tank creature. Seemed appropriate on many levels.
Now, onto the crossover. Nothing too complicated. Mostly 2nd order electrical filters and L-pads all around. The mid has a notch filter (C4 + L3) at 4500 Hz, because the mid does have a bit of a breakup, and it's worth the few dollars in parts to get that hash out of the way when cranking these things to 11.
The parts count has some wiggle room in it. What's shown is what I'd consider middle-of-the-road; nothing fancy, but no cut corners, either. I paralleled an electrolytic + poly cap on the mid circuit for [potential] sonic benefits, however there's no reason one couldn't use a single 65 uF cap instead. Likewise, the L-pads use the Dayton 10-watt non-inductive resistors in pairs, which brings the power handling up to 20 watts each (which should be enough). Someone could just as well use single 20+ watt wirewound resistors for the L-pads and it'd be fine.
My total is $310; with the cheaper substitutions above, it was around $290. Of course, you can always shop around for components as well....

Interesting looking speaker. I heard the small Von Schweikerts with the Fostex Mid's earlier this year, and was quite impressed. Are there any other sources besides Von Schweikerts web site with info on the above referenced speakers?
I'm looking forward to seeing a completed build here, sorry about the garage crack, I honestly thought that's what these were for, MY Bad....
Back to lurking now,
John
