Would this 3010MB driver be any good for amplified DB?

Seems intended more as a midrange. Probably best with a different driver to cover the low range.

If you don't already have it, the cab design doc can be found here: Eminence Designer (datasheets.pl)

There are two designs in the doc with F3 down in the low-mid 80hz range.

 

I modelled them some time ago to see if they’d work for DB and dropped the idea. I can’t find the model anymore and the specs are not in the eminence site anymore so I’m not entirely sure. I remember with a small enclosure and a lot of port I could get the kind of low end out of them I like for DB. That is: not that much bass and a slow descending curve from about 100 hz down. Not enough for EB, think vintage GK 200mb. For my taste (and I think for most people) these speakers also need an extra mid.

So the short answer is: yes it is possible. It is not the most logical speaker to use for a small DB cab. If I already owned them I’d give it a try.

 

This driver in a small box sounds better to me than anything. May have been discontinued but still available.

In both of the designs shown, "Fb" is the port tuning frequency, 90 and 80 Hz respectively. Since the lowest E is about 41 Hz, these designs would both run into performance issues if not outright driver damage if used with upright bass. When you operate a speaker below its port tuning, the excursion of the cone goes through the roof, and it becomes very easy to push the speaker beyond its mechanical limits, not to mention, response is dropping at 24 dB/octave.

These drivers seem OK as a midbass in a PA system, but unfortunately not for stand-alone bass use.
