Those seats rock!

So does this one!

They rumble too with the Bass Shakers inside...

oh man, you didn't say that. :)) My ep600 and twin 350's really pound the room that I can feel, can't imagine shakers...

If I ever get around to building my 2nd sub to match my SVS PCi 20-39, then I will have something to really shake about.

The room will respond better with the 2nd sub, plus the acoustical panels will help overall, and the bass shakers are just fun. For those that haven't read my wordy build thread, I don't like to crank the shakers up too much, but boy do they help with things like a racecar's engine rumble, or a rocket/spaceship. You get the feeling of sub-audible LFE like nothing else, even when set pretty low.

Here is a great site with very tasteful products. Similar DIY could be had for a fraction of the price and similar performance since you know what you are doing obviously.

Drool! You've got a great space. Read the build thread. Kudos.

They don't have any resellers in the US it seems. Their home page says "coming in January" but I didn't see how to get to a US product page.
