GK MB112 II... blew the speaker first night in my bedroom? Replacement options?

The upright signal wasn't super loud and I had the bass circuit on the EQ up to about 3/4, just wondering if it's too much low end for this speaker design.

That's not impossible, and it depends on your bass and what you use for a pickup. Sounds like a lot of bass, though...with the upright I always have to cut (a lot) to get a usable tone, I certainly wouldn't boost the lower frequency bands.

I use a Realist and it is boomy as f*** : I have to use a hpf and cut the 160 Hz EQ band on my amp to -18dB (all the way down, basically) to prevent mud and feedback. It seems extreme, but it works for me, and still sounds very much like upright bass.

Thought I got a great deal for $150, the MB112 ii sounded great trying it out, sounded great at home, and then I plugged in my upright (fairly low signal level from its pickup) and played with the volume a little over halfway just to see what it'd sound like, and now the speaker does not reproduce low frequencies without terrible distortion. Is this amp seriously designed so that it can blow its own speaker at nowhere near top volume?

Anyway, I obviously don't want to put the same speaker brand back in it (the stock one is unlabeled), so anyone have any advice for a replacement, or know if the factory 12" driver is 4 or 8 ohm?

Just replace it with an eminence. Made in the USA SOUNDS GREAT AND INEXPENSIVE :)

I'm gonna give GK the benefit of the doubt on this one considering it was designed for electric bass and I blew it with an upright. Fwiw though, the pickup is not preamped at all, not sure the brand of it as it came on the bass, it's an under-foot piezo style and is nowhere near as hot as the K&K bassmax on my other upright. Maybe someone can clue me in here, I hear ya on getting good tone through EQ cutting rather than boosting, but if I've got the low end boosted and the gain down, shouldn't the power to the speaker be about the same as cutting the low end and boosting the gain? I regularly play through a Peavey 15" that came from a TNT100 and have never had issues. This is my first 12" amp, was hoping for something that wouldn't take up the whole car with an upright. Can't seem to find any such drivers in stock anywhere in town, so I'll probably just order the OEM and treat the amp very delicately.
