amp hookup,filter and clip limiter settings

[jrc]

Hi
This is my first post here. Thanks for all the great information. I am just setting up my IB Sub. It is a line array with 4 ea AE IB15" drivers(with phase plugs). The sub is located directly below my Pioneer Elite RPTV. The face of the baffle is flush with In-Wall Left Right Center speakers. The back side of the baffle is vented into an adjacent store room which is 1000 Cu Ft. The HT room is about 6000 Cu Ft. I am using a QSC RMX1850HD amplifier for the sub(360 W per ch at 8 Ohms stereo). HT setup is B&K Ref50S2 processor & B&K Ref200.7 amp. The Ref 50 has room eq and three notch filters I plan on using.
Some questions:
A) How should I wire the drivers? two drivers per channel in series, stereo mode? I am not sure of the ohm rating of these drivers or how much power they need.
B) Should I use the 30 Hz filter on the QSC Amp to be safe or will that cause me to lose bass below 30 Hz? I think the QSC amp has a 5 hz high pass filter in it. I sure don't want to bottom the drivers on War Of The Worlds.
C) Should I use the amp's clip limiter? I am not sure if this is for high freq's only or if this will protect the drivers on low freq’s as well.
As you can probably guess, I am a newbie and appreciate any suggestions from any of the knowledgeable experts on this great forum.
I can hardly wait to turn this thing on! Thanks for your time!

Regarding the IB-15s, John recommends 200 W/driver.

The ohm rating should be on the driver on a sticker, either IB15-4 for 4 ohms or IB15-8 for 8 ohms.

Don't use any of the filters. Doing that sets the 5Hz filter automatically. If you use the 30Hz filter, yes everything below 30Hz will be filtered out.

You don't need the clip limiter, you'll bottom the drivers long before the limiter kicks in. I doubt there's an audible difference if the limiter is in the circuit. Try it both ways if one sounds better use that setting.

To start out wire two drivers/channel to create either a 4 or 8 ohm for each channel (this of course depends on your speakers). If that not enough output we'll rewire later.
