Phenomenal Shallow Sub

The following review is for MPS 250 S2, which is a part of the bundle you are viewing.

Its amazing how far technology has come. This shallow sub is accurate and powerful. Have it in a .5 sqft sealed box with a 500 watt RMS amp. Precise and punchy. Performance is on-par with costs.
