I have no plans to build stereo subs. I believe that your perception of directionality (or "stereo") is due to room excitation (resonance). If you were sitting blindfolded in an olympic sized swimming pool (obviously unfilled), and a sub was placed 10 or 20 feet from you in any direction, and a 40 Hz warble tone was played right in front of you at 100 dB, you would not be able to tell me where it is coming from. I have read that the absolute minimum threshold of bass directionality is 80 Hz, and that the average person can distinguish directionality at about 180 Hz. Those are not really subwoofer frequencies though. I think the whole point of a "mono" subwoofer is that you shouldn't be able to distinguish directionality. Now, if you want increased output without building gigantic 3-ways or a refrigerator-sized sub, sure get two smaller subs. But as far as directionality, that's utter rubish.
Edit: I should emphasize that, in practice, most subs probably are operating somewhere b/w 80-180 Hz. If that's the case, then sure, you can probably hear it. I specifically said, I want my subwoofer to only play the absolute lowest (true SUB-woofer) frequencies. IMHO, anything above 40, to be safe 60 Hz, is better left to midrange or smaller woofers than the sub. But whatever floats your boat. -- ezkcdude ------------------------------------------------------------------------ ezkcdude's Profile: http://forums.slimdevices.com/member.php?userid=2545 View this thread: http://forums.slimdevices.com/showthread.php?t=20197 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
