HDX3 Series Subwoofer Selection

(6 customer reviews)




Order Processing is Two Days

Take your competition-level, demo system to deeper lows with more excursion with the HDX3 subwoofer. For a daily-driver systems the HDX subwoofers are less power hungry than the discontinued HDC series. Big boxes and wall projects will get more excursion at high power to really get air moving for hair tricks.

The motor features a thick top plate, high motor force, and tight gap for a high-efficiency speaker design. A taller 4-spoke, cast-aluminum frame makes room for a larger diameter spider. The larger diameter spider’s new roll profile allows for the Fs to come down without sacrificing power handling or control. A taller and slightly wider surround allows for additional excursion. New pulp-blend cones are stronger and lighter than previous fiberglass-laminate designs. We are also ditching the stitching!

Other improvements to the HDX3 subwoofer include a thicker aluminum former, black anodizing, double slit, higher temperature resin, and a beefier U.S.-made coil.

    Great sub. Just what I wanted. Hits hard with great detail and the lows are awesome. Thanks SQ for making a low end monster.

    Got the HDX 18 recently and still breaking it in. Already exceeds my expectations by far and I’ve had HDC3 15 in the past

    Coming from a long time customer all the way back to 2006 when it was audioque this is the subwoofer I’ve been waiting over the past few years. This HDX gets very low and sounds great doing it. It remains me of a hdc3 with massive low end and it still gets very loud.
