Subwoofer Plug

Howdy, how to do you get or make a good subwoofer plug? I have a pair of SVS subs that I'd like to plug and, given that I'm trying to blend subs with Maggies, any sub I get in the future will either be sealed or I would like the option to at least trying a port plug. Problem is that unless it comes with one I have zero idea what to do. I suppose I could throw my dirty laundry in there, but that doesn't seem optimal somehow..... I should probably stick to clean clothes. ;)

What you want is an "acoustic suspension" subwoofer. This is NOT the same as a "sealed" subwoofer, and even less a ported unit with the port pluged.

Aewhistory... If you google "acoustic suspension" you will find good info.

The acoustic suspension concept is to replace the mechanical springiness of a cone speaker with the springiness of air trapped in a closed enclosure. It requires a speaker with cone free air resonance on the order of 12 to 14 Hz. (Hold one in your hand and it flops around like a dead fish). Such a driver cannot be used with other types of enclosure. Few if any drivers are made today with suitable characteristics. Low distortion is the primary benefit, but a significant secondary benefit is that the appropriate enclosure size is relatively small.

I am old enough to remember when AR came out with their first speaker, which was the AR1...just a woofer. Then they added a high end driver, and the AR2 was born. It blew away every other speaker on the market.

Maybe it is time for acoustic suspension to be reborn. Most present-day audiophiles have never heard true AS, and their reaction might be similar to what happened back in the day.

Dhl93449... For true AS the driver must be quite specialized, and completely useless in a ported enclosure.

Just curious, but have you ever held in your hand a 10inch driver with free air resonance of 13 Hz? Such were in my KLH12 and KLH5 systems. Question 2... can you find such a driver on the market today?
