  DS1502/DS1510 CI - Direct Servo subwoofer
15" sealed sub for custom installations
DS1500 kit

Introducing our new custom range of subwoofers

There are many benefits to a custom subwoofer product. For those concerned with spouse acceptance factor, often a subwoofer is best felt and heard but not seen. For others, a subwoofer should match the interior of your home. Either way, our CI series products are the ideal choice. Have it built by a local trusted furniture maker, or if you are handy, you may choose to built it yourself.

Our ds1502ci vented subwoofers feature the same components as our FVX15 subwoofers. This subwoofer features our DS1502 sub driver which is available in silver aluminum. Also featured is a subwoofer plate amplifier of your choice from our range. The sealed dual ds1502ci subwoofers feature the same components as in our F25 subwoofers.

Your choice of enclosure

Direct Servo technology can be applied to any enclosure type - it is not limited to sealed boxes. If you would like to use an enclosure other than sealed or vented, we can design a custom servo board to ensure you receive all the benefits the technology allows. For a vented box, we recommend this product over DS1200ci. Contact us if you would like to create something different.

Subwoofers for audiophiles

For audiophiles looking for uncompromising accuracy, our subwoofers are the ultimate choice. They features our Direct Servo technology to ensure accuracy and definition. We don't merely design low distortion subwoofers. We are concerned with eliminating the problems which most degrade the accuracy of a subwoofer. Problems like memory effects which are clearly audible are dramatically reduced. Perhaps you already own a subwoofer but have been disappointed to discover that it added more than extra depth. Or perhaps you have avoided purchasing a subwoofer because you were unwilling to compromise the accuracy of your system. Rest assured that you have found a subwoofer for audiophiles.

Better technology

Nearly all subwoofers on the market are based on outdated technology. Our subwoofers are based on our patented Direct Servo technology. Not only does our technology surpass that of conventional subwoofers, it also offers significant improvement to the performance of other servo systems. In our technology section, we describe the differences between Direct Servo and other servo technologies. Our system is better suited to music reproduction than other servo systems.

Amplifier and driver options

DS1500ci features your choice of two amplifier options. A370PEQ features parametric EQ and our A370XLR has balanced inputs, making it ideal for studio use. More information on our amplifiers >

The standard amplifier is A370PEQ3 (370WRMS PEQ). The quickguide of the PEQ3 amplifier for sealed subs can be found here while the vented version quickguide can be found here . PEQ3 amps do not have high pass filter RCA outputs. But it does have dedicated LFE inputs allowing for easy integration of a 2-ch-plus-HT system setup. PEQ ampplifiers are available for those who still need high pass RCA outputs for non-AVR and non-prepro setup. The quickguide of PEQ amplifier for sealed subs can be found here. PEQ version is available for A370, not H600. The response curves with various extension frequency/damping combinations of both amplifiers can be found in our EQ page.

We also have 4amplifier options:A370PEQ, A370PEQ3, A370XLR2, and A370XLR3. A370XLR2 has one XLR input and one XLR output. The XLR output can be either used as master slave signal transmission, or for HPF output of the XLR inputs. A370XLR3 has two XLR inputs. Both XLR models have one band defeatable PEQ, 12V trigger input, and separate limiter ON/OFF switch.
