Introduction

In tough economic times, shoppers are always looking for a good deal. Enter the Cadence CSX15 MKII. This brawny subwoofer tips the scales at a hefty 88lbs and packs a 15" driver in a computer tuned slot ported enclosure with a 300 watt rms rated amplifier. All of this hardware carries an MSRP of just $499. The fit and finish is as quality as any other subwoofer we have seen in this price range. Listening to the CSX15 MKII's contribution with various music and movie selections proved that it did have a bite to match its bark and that plenty of headroom was on tap to get very loud as one would sort of infer going in from the 15" driver and vented enclosure. However extended movie watching sessions and outdoor measurements soon revealed a fly in the ointment. We found that the CSX15 MKII was caused considerable distress at times by deep bass frequencies which adversely affected its ability to powerfully anchor the LFE channel as part of a high performance home theater. Read the full review to find out why.

Thanks for the thorough review of the Cadence CSX 15 II. In a short span of time you have come to be highly respected for your subwoofer reviews, (unlike some professed reviewers).

Someone who thinks that suggesting the addition of an additional 8 ounces of poly fill doesn't qualify as “doing design projects”, nor does suggesting that screws be replaced with “T” nuts …

Keep up the great work. Your technical expertise in measuring critical data makes your reviews truly superior to much of what is passing for reviews that lack a single number, especially the base frequency response. For example one so-called reviewer thinks that a subwoofer with a passive radiator is an “acoustic suspension” design and doesn't know that a sub with a single driver and a single passive radiator behaves much more like a ported design rather than a sealed design.

All the other reviews – whether or not they contain numbers – greatly exceed that which you contribute, which amounts to essentially nothing but sarcasm, in this and every other forum. You really need to back off and go find something productive to do. Your incessant jabs and hollow comments have no value to anyone but yourself. Self aggrandizing has no place here. Move on already.
