Ask the Expert: Recommended bass cabs and what makes a bass sound good or bad

Peter from Canada asks:

“Now that I have the bass lessons, are there any ideas of a bass cab for church settings?

Our church people don’t seem to want loud bass. But I don’t know what spl that would be.

Being a technical person, I plan to build my own bass cabinet using two Eminence Delta-12LFA drivers in an approx. 6 cu ft vented box.

I’m also interested in what makes a bass sound good or bad – relative to the frequency response given by the strings.”

What would you recommend to Peter?
