If you have a preamp, I would HIGHLY recommend the Schertler Pub 2/280 speaker. It is a 280 watt bi-amped full range 8" speaker that will sound better with upright than any bass amp, with lots of power to spare.
I generally use it with my Schertler preamp, and I have used everything from microphones to piezo pickups to the Schertler Dyn B with it, and it sounds great.
Little testomonial from last night:
Got a call to play with the world's loudest sax player (I wish I were kidding). Normally at this club, I just run a mic on a stand into the small club PA. I knew that wasn't going to work at this volume leve, and my other plan would normally be to use the Schertler Dyn B. Unfortunately, when pushed too loud, the Dyn B isn't as microphonic, so I pulled out the Schertler Stat B, which sounds better at high volumes. I keep one for big band gigs, etc.
My plan was to run the Stat B into the Pub Speaker fairly loud, with a litte of the Dyn B into the house to fill out the sound. I went there yesterday afternoon to set up, and left the levels right where I wanted it.
At the beginning of the gig, I asked the sax player if it was loud enough, and he asked me to turn up some more, so I turned the speaker up a little more and he was happy. Played the 4 hours, and was really happy with the sound, as was the band. At the end of the night when tearing down, I went to the PA channel to turn the Dyn B down before unplugging it and discovered it was off!! I guess a bartender, trying to adjust the muzak before we got there, had turned down the wrong channel, and I never bothered to check,as it has never happened before.
So, that little 8" speaker was supplying a lot of bass to a big noisy club with a sax player who plays everything sfz....
Downsides are it is heavy for such a small box at 44 lbs. You can check it out Invalid Link Removed . It is JUST a powered speaker, so you need a preamp to control gain and tone. All it has is a volume knob and a ground lift switch.
I like it so much I'm getting another so I don't have to depend on crappy speakers at clubs. I'll use a small mixer and with the 2 speakers, it will serve as our PA system for small casuals and such, running bass, keys, and vocals.
Price retail is $740, but you may be able to get someone to deal a little to keep it to your $700 ceiling.
Scott Reed who is around the list occasionally uses 1-2 Pubs on his gigs with a Fishman Full Circle and really likes it as well.
