Talking about ARC, subs and more specifically the SVS SB1000 that someone was asking about. I just replaced my old HSU ported sub with a pair of SVS SB1000's which are sealed subs. The reason I chose a sealed sub over a ported sub was because a sealed sub has a shallower roll-off compared to a ported sub. By using two I can compensate for the lower output compared to a ported sub at its resonant frequency (as well as improve the rooms bass response and listening area).
However while that all sounds good on paper, actually achieving it in real life is another thing entirely! Having read a few articles on the best places to position dual subs I was quite disappointed to see the results when I ran ARC. Massive drop in frequency response from 35hz or so, with ARC applying a very steep 7th order slope.
I then spent the next week or so, moving the subs around the room trying to dial out the hole in the frequency response. Incredibly frustrating, power cords and cables everywhere, the problem is that with two subs the number of possible positions is almost limitless! After a week I was nearly at my wits end! When at last I arrived at a position that offered a much improved frequency response over most of prime listening area.
Much better! Now ARC is only applying a 1st order roll-off. But more importantly was the instantly noticeable improvement while watching content. So if at first you don't succeed, keep trying! As far as I'm concerned the Anthem paid for itself in that one exercise alone.
As for the SB1000's, great! They look good and are much smaller than their ported cousins. Only niggle is the status light on the front which I wish wasn't there or could be switched off (both the subs ended up on the front wall). But I may just dab the lights with a permanent marker.
