Baffle Step Response in WWTM ?

Eton · 4th November 2006, 01:01 AM

Do I still need a Baffle Step Response circuit if I’m using 2 woofers in parallel which increases the SPL by 6 B in a WWTM configuration?

Thanks

3dB bsc for stereo is o.k since its not a bass helper woofer situation. You just create a 6dB stronger woofer when in parallel, still with same step contour.

It depends on the baffle width and crossover point. If you are crossing at the appropriate point and the woofers' net response is 6 dB higher than the mids, you can skip a BSC circuit. Check out The Edge from www.tolvan.com for an excellent, free baffle step simulator

Thanks for advice and link.
Since the baffle is 10.5 inches long that translates to frequency of 431 which is where I intend to cross over the midrange. So I guess I will not need the BSC circuit.

Don't employ 6 dB full bsc by any method. Only 3. In stereo the 2 speakers are gonna correlate up to the hundreds region due to their relatively long inter-distance related wavelength. Your in room power response (in other words what you gonna finally perceive) is going to be bass heavy with 6dB of bsc.

Put one of the woofers on the back then you won't need any
