Please use a 2 channel or 4 channel amplifier. Audioex is good for single magnet 8in or 10in subwoofers. This subwoofer is 10in and has double magnets. Amplifier won't match this subwoofer. Either you may get low bass or crackling sound from the sub due to inadequate power input.

Thanks...

The 10" DVC has been mentioned as ideal for ported enclosures, having said that we are working on a recommended box dimensions or Quarter wave and Ported designs ,both Slotted and pipe ports. We will be shortly publishing these designs. Could you elaborate why you are looking to build Bandpass enclosures?
