I think you are talking about the EMB-1000... the one with the metal passive radiator. The model I'm talking about has just a 4" port exposed with two internal woofers.

Are Isoberic Subs any good such as James 10SX?
I'm doing a HT room (will use it for multichannel music as well) and would like to build in the sub. James audio has a built in isoberic (bandpass) that should allow be to just expose the port to the room resulting in a very low visual impact. I typically associate these designs with car audion or low-end home audio but that might be short sighted..
