Default PA Subs w Amp

When looking at amps w built in Xover make sure that it allows Xover point in range of 300Hz. This will apparently allow better power output for the speakers from the amp. Remember, a subwoofer for pro use is much different than in the home. To get high output of below 40Hz can be costly. Get a GOOD!!! power amp that has a fan and good warranty. Be cautious with unknown brands. They may not be around in a year or two when your amp goes bzzzzppppppttttt during a show on a hot summer afternoon. Then you are stuck with a boat anchor. For the subwoofers, consider the venue. If you are playing in clubs with less than 500 people( a decent club will have adequate PA ) 4-6 short throw bass horns or Dual 18 scoops will kick butt. Outside= many other problems. What type venue do you usually play? Also, what type music?

HI, thanks, It's not really for me, it's my brother's band. I told him that he really don't need a subwoofer that goes as low as 30Hz. The real dynamic of PA music is around 70 to 125 Hz.That way , need a much less powerful amp. I told him that maybe 2 Eminence Kilomax 15A with 1250 watts and 99dB would be OK for him.Maybe if I can get more information about class d amplifier, could build some to to put inside the box with external heat sink as well as a fan.Right now he drive two Peavey speaker with 15 in. driver. Could incorporate built in crossover at maybe 120Hz. Could tune the boxes at around 45Hz. Btw, is the electronic crossover really needed,does he have to cut the bass on his
Peavey speakers or play bass on the Peavey and the sub with two different amp. Thanks for any advice.

Yes, you do need an electronic crossover, the whole point of sub-woofers is to take the bass out of your existing speakers, allowing them more breathing space, and to be louder on mids and highs.

You can also get passive crossovers, which means you don't need a seperate amp, but that way you're losing power rather than gaining it.

The amp 'Buttkicker' above is only a home amp, not suitable for PA use - you want something sturdy and reliable.

The buttkicker device is harder to drive that a regular loudspeaker.

They make a version of the driver for pro sound use. The amplifier they sell is designed to drive two of them, a very difficult 2 ohm load (nominal).
