8 inch or 10 for a Vibro-Champ build?

Single 6V6 in a Deluxe sized box.

SWEET!!!

(2-8's sound pretty cool too though. My last one was a 4 ohm twin 8. Lot's of spank)

I've had a number of Champs and think that Leo got it right with the 8" speaker. I currently have a Weber Sig ceramic smooth cone in my SFVC and it's excellent. IMHO, if you want a 10" get a Princeton. If you want a 12" get a Deluxe.

 

I voted 8"... after thinking it over.

I am siding with a few folks that say the 8 works. That said I did use a 10" on my 5F2-A ONLY because I added a few mods and my coupling caps are mimicking the 5E3 with a .02 and .1uf. The 10 removes the so called farty-ness.
I dig a vibro with the 8.

 

i think you'll find that all guitar amp's are not "open back".

 

I've only used an 8" in a Tweed Champ I built, but there's something about sound & tone that is unique to an 8" speaker. I used a Jensen C8R and had no complaints. They are remarkably full range speakers if you try them with an ipod/stereo setup. Full bass, clear top end, I was very surprised.

Anyway, with the tweed Champ, I've tried it with 10's & 12's and nothing sounds bad, but the 8" had the most vintage sound and just sounded right to me.

 

OP said he may gig with it. When I try an 8" in my studio, it sounds like heaven, but take it into a larger room and it is absolutely lost. A 10" is more useful in either case to me. Maybe don't be so concerned how it sounds to you personally, but what it will be used for and what it may sound like to someone else. Get a 20' cable and stand over there. Now what does it sound like?

10 inch speaker in a Vibro Champ whoops!

I cut the speaker hole bigger and installed a 10 inch 4 ohm Peavey Scorpion and the amp sounds huge.

 

Yes. And it's spelled Öyster.
