I always wanted some kind of sub eq. but when I was looking into it a few months back they seemed way too expensive.
Then recently I started looking at reviews and such on what was available and @ $354.00 for SMS-1 and comparing it to other models I think I made the right choice.
I was very close to getting the Anti-Mode 8033
for $350.00 since it has standing wave/time correction. But my Pioneer has that.
The reviews seemed really impressive on the Anti-Mode, just wasn't nearly as flexible and no on screen/real time display as well.
I give the SMS-1 a great recommendation for the price, but if you already have room treatments and/or a good acoustic friendly space, then you wouldn't really need one at all. In that case, any eq won't make a big enough difference to justify the money spent...IMHO.
