Does anybody make a true 8 inch diameter Hi Fi woofer any more?

[carlspeak]

Seems like most available today for DIY'rs are a little over 8 inch diameter or a little under, but not exactly 8 inch.

Do you mean the outer frame or the cone?

Well, you know some people have gone metric. The Dayton DC200-8 is 8.07" (205 mm) outer Dia. Probably as close as you'll get.

I'm trying to find a woofer that will fit flush down into an existing baffle board rebated shelf. The Dayton would fit but one look and FR and I'd say it doesn't qualify as a HIFI driver.

I just knew you were going to say that. Being well on the way to deafness, I enjoyed my Dayton 8s.

The Peerless 830869 is 8.07" across the flats, if that does you any good:

Doesn't Scan still sell the old Vifa P21?

Nice looking project. What's that white material on the front?

For that woofer, Madisound's site is showing an OD of 21.5 CM. That's almost 8.5 inches. My max is 8.06 (20.5 CM).

My rebate is round and only accept up to 20.5 CM. The peerless has an OD of 22.5 CM - no go.

I'm looking at the SS 18W/4531G00 @ 18.2 CM. I'd have to surface mount it on an adapter board. There is some concern about diffraction but the edges at the OD of that SS woofer are nicely rounded over. Still might work though. It's got most everything else I want.
Anyone paired this woofer with a Dayton RS28F-4 tweeter in a design?

Well, it's a light gray actually. A bit lighter than I had envisioned. It's 1/2" mdf over the 3/4" cab material, painted with Rustoleum textured paint. Matching base.

HiVi F6 is close at 195.5 mm. Great midrange quality, would be easy to integrate with the RS28f. Won't have the bass of the Scan 18W, but won't have the price either.
