And of course the limiter won't be functional, which increases the possibility of damaging your speakers. Quote Link to comment Share on other sites More sharing options...

If that's not loud enough chances are your speakers are insufficient for the job, no matter what they're rated, and sending even more power to them probably will lead to a less than desirable result.

How they function should be explained in the manual. If it isn't a conversation should be held with the amp manufacturer as to why not.

waynepunkdude Posted October 3, 2009 Author Share Posted October 3, 2009 All the manual says about the limiter is "24. LIMIT: This LED illuminates when the internal limit circuit is activated. This indicates that the amplifier is nearing full output and the limiter is keeping it from clipping the output signal." Hmmm I'm guessing the 15" is causing it as that is 300W, might be worth investing in a new cab. Quote Link to comment Share on other sites More sharing options...

Its if you are cranking the 15 side because theres not enough volume from the 15, that you need a second 15. Guessing you are running the classic 1x15 and 4x10. Probably the 4x10 is more efficient all round, so you are getting plenty from that, but the 15 is struggling to keep up. What you really want is a 6x12, will cover everything you are after. Totally trying to explain the 'don't mix speaker sizes' thing without being as much of a douche as I generally think people are when they say it. But I kind of understand it. As a person who lights up clip lights a lot, the problem is probably with your cabs more than your amps.More cabs and more effiecient cabs (sensitivity rating) will probably do more for your volume than anything else. A 2x15 will probably balance volume wise better with a 4x10, and the correspondingly bigger box will give you lower, unless you go for a 2x15 in a 4x10 sized box, when it all falls over. Ah, beer makes this hard to explain. Get big cabs and loads of them, and loads of heads, and be Doom. Awesome and Manly. Quote Link to comment Share on other sites More sharing options...

The 'classic' 1x15/4x10 is a poor match up, not just because the 1x15 handles less power but also because it has less sensitivity than a 4x10. A 1x15 works OK with a 2x10; to keep up with a 4x10 you either need a 2x15 or another 4x10. Quote Link to comment Share on other sites More sharing options...
waynepunkdude Posted October 4, 2009 Author Share Posted October 4, 2009 (edited) Right as I don't have the budget for another 15" ATM I have a few choices. I could use just the 4X10, I could put both cabs on the same power amp, I could turn the limiter off or as they are bi-amped on a cross-over I could give the 4X10 more to do. Which would work best?

Leave it there, but don't use the 15 and see what its like. Try those things and see what they do for you. Quote Link to comment Share on other sites More sharing options...
waynepunkdude Posted October 4, 2009 Author Share Posted October 4, 2009 (edited) TBH I only use the 15" for the low end which is usually loud enough, as long as it's not cuting the 4X10 then awesome. But I will try all the options out, maybe I shouldn't have sold the 6X12 but I had extreme Stingray GAS.

Alien Posted October 4, 2009 Share Posted October 4, 2009 You could try lowering the crossover frequency, which would have the effect of making the 4x10 do more of the work. The biggest problem with using a standard 1x15 (or pretty much any bass cab really) as the low end in a biamped rig is that they're not really designed for it. What you need is a sub of some kind - a PA sub would do fine. A Quote Link to comment Share on other sites More sharing options...

What counts isn't the thermal rating, it's the displacement limited rating, and no one provides that. Try before you buy. Quote Link to comment Share on other sites More sharing options...
