RE: Help Needed Selecting The Right Hi-Efficiency Subwoofer

Posted by Mr. Lowther on May 6, 2017 at 08:44:04:
Hi Tom:

Integrating a sub with these is a bear. First, because the horn is loaded by the back of the driver, it means that bass is out-of-phase. And then, because the bass has to travel through the horn path, it has a delay. If at all possible, get a subwoofer amp that has variable phase response. This allows the best integration with the time delay of the horn. Be prepared to spend some time getting integration right. For what it is worth, Rythmik subwoofers are what I prefer.

If you really want high efficiency, plan on building a closed box and then equalizing the bass response. Only alternative is a really huge box. The AE TD18H+ is a fine choice for a DIY project.

Best,
Jon
