I was building a '59 Fender Bassman style enclosure. Not sure which kit I'll get (Mojotone, Cieratone, Weber kit ... haven't decided).

It was in the back burner so I decided to bring it to the fore-front.

Don't know what I was thinking. First my dimension was reverse, height was the width, width was the height and worse yet I was a 1/2" short.

4x10" speaker baffle cannot fit.



Yes, there's ways to make it fit but I would be risking some of the "support".

Solution 2x12!

The original was 4x10.

How 'bout 4x8? There's something you don't see every day - a mini-Bassman!

lol - yeah, I posted 2x12" diagonal and someone suggested [ joked ] "Why not two 8"s on the corners while you're add it. Laughing

Two 12"s ought to work. My first amp was a Tweed Bassman combo, but in a 2 x 10" cabinet (Emi Legend 1058 speakers). Sounded very good. A floating baffle is a key contributor to the tweed Bassman sound.

Thank statorvane, coincidently this is my first attempt at "floating baffle" I always used speaker baffle and grill frame separately. But I can't do this with Bassman-style enclosure.

Do you know if 5/16" thick plywood speaker baffle is another key contributor to the tweed Bassman tone? The image I posted with the 4x10" speaker baffle is actually mock up with 3/4" thick 5-ply cabinet grade plywood. I usually use 9- or better ply cabinet grade plywood or import baltic-like plywood. Real baltic plywood is expensive!

I think the skinny ply baffle is definitely a contributor to the tweed Fender sound.

The way it's hung-- from the top and bottom and floating free on the sides-- and the fact that it's so skinny lets it act almost like a "diaphragm." This along with the resonant nature of the pine cabinet makes the amp a little more "diffuse" sounding than, say, a stiff plywood box. I always hypothesized that this is why nobody ever seems to miss reverb on a tweed Bassman.

Yes, I think Tange nailed it. That and the pine cab. I built mine out of poplar - cheaper than clear pine and sounds about the same. Easier to work too.

Thanks statorvane, tangelolemon Wink

Yeah, this project is prototype and going to be an extension cabinet.

Yes, I'm going with sugar pine (knot-less) and I think 10mm plywood is closest to 5/16" thick plywood unless there's a 7mm thick plywood for the speaker baffle.

But going with through-dovetail not finger-joint. I hope finger-joint isnot another of the Bassman tweed mystique. Laughing

Yes, I like poplar. The above picture with 1-12" cane wick grill is poplar with 1/2" blind dovetail. It looks like maple. It took a beating.

haha, I have a hard time imagining dovetail vs. finger joint will matter!

To tell the truth, none of it matters, and all of it matters.

In the sense that many little things can make a tiny difference, but the sound still comes from the player, and actually having some music worth listening to is down to the player, writer, the rest of the band, the room they're playing in, the guitar, the pickups, the amp... and on and on and on and on, and WAY down the list is the way the amp cabinet is made!

Aww man ... once I get the 5F6A kit installed I was going to play it through a chain of stomp boxes, pedals, modeling boxes ... and a pointy headstock electric. Mad
