Thiele info & Advice Needed!!

[Ken j]

Thanks for the replies everyone. Keep them coming. One thing I didn't mention is that in a Thiele and Small design it is best not to use even dimensions or in other word numbers that can be divided equally into each other. That will set up standing waves in the box. Example 1'x2'x4'. A cubed box is the poorest choice, 1x1x1.

gts I would be interested in the box dimentions (internal) and port design , if you have time. I just need to get my email up again.

My guess is the EV's box dimensions are ideal and Mesa altered them so that it will match their cab.

Thanks. My email is back up.

hey guys, i just got a used thiele at guitar center, it says c90 at the back plate where you plug the jack, but when i opened the back part of the cabinet to check the speaker itself, theres no label on the speaker, im afraid that the former owner of this cab changed the speaker! anyone here have the original speaker? does it have a label on?

Is there any print on the back of the speaker? What does the frame look like?

I have had one just like this. Look for a vent in the center of the magnet and a series of numbers stamped in ink on the rear face of the magnet. Most OEM thieles do not have a sticker on the magnets that I've seen.

what dya mean by OEM?

 

[JOEY B.]

If you see the vent and the ink stamp, it is the original C90 or OEM (original equipment manufacturer) speaker.

 

[willrock]

yah, its got a vent in the center of the magnet and the ink stamp too! so its a c90!

EVM's have a vent and an ink stamp too when OEM. If you can't determine from the stamp thenthe easiest way to determine speaker type is to look at the basket and cone to determine what speaker it is.

it has a celestion sticker at the back of the cab. not unless evms are celestions?

 

[JOEY B.]

If he has a Celestion jack plate and the EVM-12L speaker, he has bought it dirt cheap, I hope. I was just blasting thru two EV Thieles with my C+ head, and the 'Paul never sounded better. They will make you reconsider the need for a 4x12 cab. :shock:

Would you believe it if I put a 5.4L Triton sticker on it? Speaker changes are really easy and common.
