djronh Posted June 15, 2010 Share Posted June 15, 2010 Could I use Peavey ul15 speakers (15" x 500Wrms each) as subs in a biamp arrangement using the internal crossover in a 1000Wrms amp and Peavey 1012 speakers (12" x 500Wrms each) as tops again powered by a 1000rms amp.This would save the need for a 3rd set of speakers.Given I already have this equipment it would be an economic approach, if not the best approach to big parties.Comments?

paulears Posted June 15, 2010 Share Posted June 15, 2010 er... these are tops, not subs? A 15" and a compression driver? You could stuff a pile of bass into them but I'd suspect they'd sound awful. After all, people who buy these to use as full range cabs, usually add in a sub to give the supporting bottom end. Subs have very specific design characteristics - they give bottom end thud, and run out of steam at 200-300 Hz, depending on design. You can have a purpose designed 15" sub, and a full range cab with very similar driver - but they do a very different job. Link to comment Share on other sites More sharing options...
tolley1466 Posted June 15, 2010 Share Posted June 15, 2010 Also, if you put a load of bass into it, you could run the risk of blowing a cone and it's not really worth it. Spares for brands like Peavey are hard to get hold of. If you really need a sub, hire one in from your local rental company. Link to comment Share on other sites More sharing options...
djronh Posted June 15, 2010 Author Share Posted June 15, 2010 I suppose I knew it was the best of ideas..the ul15 matching subs (ul115) have identical 15" drivers. It is also of interest that the crossovers in the ul15 can easily be bi-amped, so avoiding powering the compression driver. Link to comment Share on other sites More sharing options...

Bobbsy Posted June 16, 2010 Share Posted June 16, 2010 Just for reference, the driver is only part of the story in terms of how a speaker sounds. The cabinet design also comes into play, big time--and, in this case, the cabinet is the right compromise for "full range", not sub. Bob Link to comment Share on other sites More sharing options...
Sound In Gloucestershire Posted June 17, 2010 Share Posted June 17, 2010 Spares for brands like Peavey are hard to get hold of. thats news to me? in response to the OP, why not just use them on the floor full range? Its not ideal and they have no pole mounting for the tops to go on where are you based? Im in Gloucestershire and have a lockup full of peavey UL to hire Link to comment Share on other sites More sharing options...

The UL15 is more a bass speaker rather than a sub box,Its rated to 60hz.It all depends on how much punch you want?A sub box will go much lower than 60hz.Dont expect the UL15 to keep up with a sub Link to comment Share on other sites More sharing options...
