Review: After reviewing other models and sizes this one made the most sense. Received this OSD IWS8 inch subwoofer speaker in February 2020, this speaker was installed nicely in the lower wall of my home and works in conjunction with my whole house ceiling speakers, this speaker is wired in parallel with another 8 inch active sub woofer that is on the other side of the house to create a balance low end respond, it is driven with the OSD SMP-100 sub amp that is wired to a 4 channel speaker switch to balance the impedance of all the speakers, when driven these speakers produce a deep solid bass that help to shape the sound nicely with the ceiling speakers even at a low volume, I am very happy with this speaker and would recommend it to anyone that is thinking of purchasing it for a whole house setup.
