  DS1510/DS1520 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.

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Nearly all subwoofers on the market are based on outdated technology.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

DS1510ci features your choice of two amplifier options. H600PEQ3 features parametric EQ and our H600XLR3 has balanced inputs, making it ideal for studio use. More information on our amplifiers >

The standard amplifier is H600XLR3 (600WRMS). It has two XLR inputs and four RCA inputs with both dedicated LFE inputs and line-in inputs allowing for easy integration of a 2-ch-plus-HT system setup. The response curves with various extension frequency/damping combinations of both amplifiers can be found in our EQ page.

For vented version, we recommend use our ports and follow the size of our FV15HP enclousre. Ports can be ordered at the bottom of the page.
