    I built a mini subwoofer with 2 of these and the matching 8ohm woofer.

    The results were AMAZING for the size of the box. Not sure if it was necessarily down to this radiator but to have the radiator EXACTLY match the woofer is a super clean, super cool look. Love it..... and the service was as good as always. Thanks guys.
