I've listened to the sub you mentioned and I have to say I was very impressed at how good it sounded for a small and relatively inexpensive package. Yes, there are better subs, but I think for that size and money they have really raised the bar. I can say that I have listened to at least 2 other comparably priced and sized subs that have a very good reputation. I won't mention the names, but let's just say they have some catching up to do. The isobarik loading allows the exposed driver to move far more efficiently and even more important stop more efficiently. I'm not sure about "just exposing the port"--that doesn't seem correct to me, but I am not that familiar with the setup protocol for this sub.
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..
