I have simulated both the driver in WINISD and found that the IWAI one has a -3db roll off at 44hz where as the peerless one has a roll of at 54hz ....
Both being a sealed box of 44L and 66L respectively , Can anybody share their experience with the peerless subwoofer i know many have subwoofer using the peerless one ...
Regards
