10" Subwoofers

Does anyone have experience of the Presonus Tremblor T10?
I'm wondering how this would compare with the M-Audio SBX-10 (now apparently known simply as the BX Subwoofer) which we use quite a lot.
In theory they both go to 20Hz.

I use MJ Accoustics Pro 50 mk IIs which go down to 13 Hz. They have Peerless 10 inch woofers in small sealed enclosures which take up little space. They cope well with the 32 feet stops.

Hi Douglas,

We have bought one for a Paramount 341 system we are building but have only turned it on to make sure it is working. No organ through it yet. Specs seem similar to BX subwoofer but the port is in the front.
