Anyone care to guess at what driver this is?

<A HREF="http://mikebw.multiply.com/photos/hi-res/5/21.JPG?xurl">http://mikebw.multiply.com/photos/hi-res/5/21.JPG?xurl</A>=%2Fphotos%2Fphoto%2F5%2F21.JPG

It's a 12" Line 6 guitar speaker, originally from a Line 6 2x12 cabinet.

The sticker on the back says "Custom Made for Line 6 by Eminence Speaker Corporation", but for some reason I think it is just one of their stock drivers with a different sticker on the back, maybe a Beta12A?

I don't have any specs for it, and Line 6 doesn't seem to have any info either.

I haven't measured the impedance. I'm sure it's 8 or 16, but that doesn't really help determine the model.

Maybe someone is familiar with the Eminence line and can identify by looks?

I guess I am really skirting the real issue here.

What I need to know is the frequency response of the driver, specifically if it plays over 4,000Hz or not.

It seems that most of the Eminence guitar drivers go up to 5,000Hz, so this shouldn't be an issue, I just wanted to know about this particular model.

If you email with model number and sticker info, they will usually get back to you with as much info as they can, even on rebadged speakers.

Great idea. Found a page on their site about purchasing OEM drivers direct:

They basically say no you can't do this, but they will cross-reference a similar model from their stock, so this should be what I need. Thanks.

I'm sure it will "play" to 4KHz. Whether you would want it to is another question. It really depends on the original application (voicing). If it was originally for a modeling amp, the breakup peak at around 2kHz will proably be manageable. If the speaker was designed to scream, well, it will scream.

It would be interesting to line up the Eminence "Blue" and "Red" guitar series speakers for a listen :-)

Not HiFi, but designed to sound just RIGHT for the purpose !!

So I got a response from Eminence, they said it is most similar to their LEGEND GB12, which is kind of dissapointing given it's 50W RMS power rating. Although it does go up to 5.5kHz, so at least I have that.

Here's the specs:

Do not under-estimate what a 50w guitar driver can do !!!!!

[mikebw]

Nope. Especially when loaded in a huge horn PA cabinet.

I just ordered the Selenium DH200E comp driver to cover the high end, these two will go together soon.

I will reserve judgement until I have it all setup.

The 101dB SPL rating is somewhat optimistic judging by their graph. The average seems to be closer to 98, with a 3KHz peak in the 105db range. This should turn out nicely.

Guitar speaker power ratings are true continuous - they are expected to be driven at that power level for hours on end. And that's why some of those people go deaf :-)

You're horn loading the driver? Guitar drivers are far from optimum for a horn cabinet.

It will probably *work*, it will be *loud*, but there will likely be no low end. But you knew that already, right?

It's supposedly the average over the useable range. That is, everything between 200 and 3-5k. They don't count the bass region where there's next to nothing, and they do count the breakup peak. Even then, their numbers always seem optimistic. I always calculate it from the T/S parameters and use *that* value.

Yes, I have plans to use a much better driver (EVM-12L) but this is what I have to use for now.

Yes, low end will poor. I ran some test tones and things started to get loud around 100-160Hz, below that it sort of trails off.

I see. I guess one number can't really do a good job of representing the performance of a driver over a wide band.
