My buddy, who's building a rehearsal space/studio on his property is starting to think about equipment. He wants to have amplifiers on-site and we've been talking about bass amps. Originally, he intended to use his Sunn Coliseum as the bass amp and buy a suitable bass speaker cabinet to go with it. Now, he's talked himself into the idea that the bass can be run through the PA. I know there are bands out there that run everything through the PA, but I have real reservations about whether this is a good idea. I don't know specifically what the PA is, although he's led me to believe it's a large commercial system. However, I really doubt that it's designed for the low frequencies and massive cone excursions that a bass will demand of it. I'd be interested to hear your reactions to this idea.
