my new 604 cabinets I'm building.

Why edge banding of course.

Your favorite lumber yard will offer it in a variety of species. I really like the self adhesive stuff, you iron it on, fast easy and neat. But, the iron on stuff works best with well sanded edges. If you need to glue it to factory edges, probably best to get the bare stuff and use copious amounts of contact to glue it down.

Cradeldorf, those look fantastic! I really like your choice in color contrast.

Impressive work for a toilet scrubber!

Wow--those are beautiful cabinets--nice job!! Have you/how are you going to determine the port size/location/cabinet tuning?

Thanks Bowtie. I guess I've seen rolls of the stuff but never used it. It looks very fancy.

Thank's Guys, Yep I used the Iron on stuff went on real easy but bubbled up when I polyurethane'd it but a little heat from the heat gun and the heavy rubber roller sank it back home. Scrubbin those toilets gives me lots of time to daydream Bowtie.

Vott I'm putting a 65 SqIn port in the bottom of the back panel That way It should do a little better job of keeping any midrange freq's from canceling out.... I hope the source knew what he was talking about. I got my port size numbers straight from the Altec "Speaker Enclosures Their Design and use" bulletin, quite a handy guide.

I'm thinking of adding a board across the front of the baffle about 2-3 inches below the speaker hole so I can do a black cloth grill across the top and still see the wood on the bottom half. Plus it will add a little more bracing to the baffle.

~12 ft^3 with a 65"^2 vent x 3/4" tunes it to ~41 Hz, kind of high for a modern HIFI app unless a sub system is used.

That's what the Altec bulletin suggested for the 604? I haven't cut the ports yet, if you got a better suggestion.

I'm still quite confused on this, especially after reading my Radio Shack "Advanced Speaker Design" book three times and doing all of the math long hand. Isn't the only frequency coming out of the port the box/port resonance and at Fb the speaker is motionless and all of the air motion is in the port and in faze with the woofer? Doesn't aiming the port out the rear, bouncing off of the wall make it out of faze with the woofer?
