Bose PA system , speaker advise needed

icewinder

I have owned an incomplete Bose P.A set up for some time but now my 18 yr son and his 3 peice band need a smallish PA to do some some small clubs/pubs so I need some advise on subwoofers.

Basically I have a couple of Yamaha poweramps (roughly 350watt each) a Bose controller 802-C, a small Behringer mixer and 4 x Bose 802's with original drivers.

The thing is , the PA lacks any bottom end so I need some smallish subwoofers. They would have to be small cabs say 10"-12" drivers in and be compatible with the Bose controller so I can run the 802's on the top. I looked at the Bose L1 B1's but I don't know what would do the job.

I don't want to spend daft money , say £300-£400 been my budget for a pair. If you can help please do. I don't wan't to sell the Bose as I love the sound from them , I just wan't to add to the PA.
