I tried out the Kef T2 subwoofer ($799) at Visions paired up with Cambridge Audio's S30's and I must say my 192 kbps test AAC and MP3s sounded VERY good. Some better than others, and I just blame the huge open environment and the lossy/sub-par compression techniques for those that sounded "meh" and average.
I have heard great things about Emotiva's subwoofers, and if I am to order online, I'll likely get the 12 inch over the 10 inch sub. I want a "musically inclined" sub and not sure if the Kef T2 is. I can say it isn't boomy, and the bass of the KEF T-2 was very tight and the music sounded really good when paired with the S30's.
The salesman who helped me said he can get me the T2 on special order (since it's not part of their regular stock) for $600.
And for $600, that is the price of the physically larger and heavier Emotiva.
So which should I get?
