I agree. When I saw the initial tests of the cooling device, I was immediately impressed and knew at once this was something that could be used on lots of equipment. I thought it would be best to make it as compatible and wide-reaching as possible. So I laid out my horn to make compatibility possible. The heat exchanger can be used with either my horn or the LABhorn, and all that is required to retrofit an existing LABhorn is to drill a hole in the access panel and add the heat tube, provided the existing access panel is aluminum. If not, replace the panel with one that is. We'll be putting them in the shopping cart shortly, at very attractive prices, less than half the cost of the woofer.It also fits other horns, and even other cabinet types. At most, all that is required to use it in loudspeaker is a few extra support braces. If the box is small, then the radiating panel of the heat exchanger can be mounted to the rear of the box. But if the cabinet is large, then braces can be added to the interior of the cabinet, which can then be used to mount the heat exchanger and hold it in place.

I'll be working on heat tubes to fit several vent sizes so I'll have heat exchangers available for many speaker motors. It really works well, so I want to make them available for as many high power speakers as possible.
