Advice on Bass Bins for PA please

[Baldrick]

Hi

We are using a Phonic Powerpod 1062 - 375W + 375W / 4 ohms with a pair of Peavey PRO 15s - 300W / 4 ohms (Manufacturers | Powerpod 1062 Plus | Powered Mixers | Mixers | 600W 10-Channel Powered Mixer with DFX Peavey Messenger Pro 15 PA Speaker at Gear4Music.com) and would like to up the bass sound with either additional bass bins or perhaps replace the PRO 15s with new speakers. I'm struggling to find a pair of 4 ohms speaker cabs with low a frequency range.

Has anyone got any useful suggestions please?

Cheers

Rick

I have a cunning plan! Get a Mackie powered subwoofer:
Mackie - SWA1501

Even the little 15" one can kick a fair amount of bass, and the 18" is a beast.

Steve's idea would probably work, but you have to set it up properly...if the Phonic allows it.

You would have to take the full range signal OUT of the Phonic directly after the pre section (main out?/pre out?, etc.), and run that to the Mackie BEFORE it hits the power amp of the Phonic.

Then the full range signal will go into the Mackie crossover, split the lows to the Mackie amp/speaker, and then send the mid/hi back out of the speaker's crossover circuit. That would then go INTO the Phonic power amp section (power amp in, etc), so the Peavey speakers are only reproducing everything above the crossover point frequency of the Mackie crossover.

Which may be a good thing. Since they don't have to thump bass, they may sound clearer and better, and be able to actually get a bit louder.

If you try to run the Phonic amp/Peavey speakers in parallel with the Mackie (both get full-range signal) then you'll never get the full advantage of the Mackie because the Peavey speakers may start farting out before the Mackies are allowed to reach their low sweet spot.

Just make sure it can do it, and something like a powered sub can work.

Make sure the Phonic will do this before doing it.

I think I understand what is being said here, take the output to the Mackie and then the Peaveys. The Phonic has different outputs and I'm sure this would work.

The Mackie looks great but it may be a bit too pricey for us but we'll consider it or would we need a pair?

If the cabling - Phonic ->Mackie->Phonic->PV is too beastly, and if the Phonic has a pre-out/pwr-in split (like an FX patch point) you could stick in an electronic crossover that would send the lows out to the Mackie, wherever it is physically, and stick the mid/highs back into the Phonic.

Something like this Behringer, maybe.
