POlk SDA's & Sub Calibration

Doug Montgomery

O.k..I'm Hawaii on Vaction/Business and have a slow dial-up..so forgive me for not doing that much searching please (I have Cable Modem at Home)

Equipment:

Denon AVR 3803
Polk SDA 1B's (Front Mains)
Polk CSi400 (Front Center)
Polk FXi300 (Rear Surround)
Klipsch (Rear Center)
Veledyne 80 watt powered sub (To be replaced )

I am building a Sonotube Sub with 4 AV15 MKII's in a IB setup

After reading alot here and at HTF, I see I need a BFD to calibrate the sub to my room (17X13 with and open back to the kitchen)

My question is, what should I buy to calibrate the front SDA's? (EQ), do I need to callibrate each speaker independantly (unhook all speakers except that one being calibrated). Can I use the white noise generator in the Denon AVR?

Thanks in Advance,

Doug

Hi Doug,

Here's a thread that may be of interest to you.

EQs. Your thoughts.

In particular please refer to my posting in this thread titled "Matthew Polk's Thoughts on Equalization", it contains instructions from Mr. Polk on how to measure and equalize SDA type speakers. Their unique design calls for an unusual approach to measuring their frequency response. Needless to say, if you don't accurately measure the response, you can't expect to accurately adjust it with equalization.

From a practical point of view you may find that the cost of the proper equipment to accurately measure the frequency response of yours speakers, and then equalize them (particularly if you plan on equalizing all channels) will certainly exceed the cost of your receiver.
