D 7SUB is designed to match the rest of the D 7 series and is remarkably compact when you consider its specifications – this subwoofer is intended to easily slot into domestic living rooms.

In order to match the D 7LCR and D 7SUR sonically we have created a monster subwoofer: We have used a 25mm thick cabinet made of very stiff MDF material, mounted an extremely powerful 15in woofer with Motional Feed Back (MFB), and powered it up with a 400 watt Class D amplifier that delivers a peak power output of no less than 700 watts! The D 7SUB reaches all the way down to 20Hz which could cause problems in some rooms so we have added a Boundary Gain Compensation filter to fine-tune its response.

According to the THX Ultra 2 specifications you need two D 7SUBs to comply with the stringent guidelines. However, experience has shown that in smaller rooms one D 7SUB is more than sufficient to get the job done. We guarantee that you will still be able to hear, and not least feel, when the T. Rex roars and starts running after innocent bystanders, or as it would probably phrase it, “lunch”.
