Up until a few weeks ago, I had been quite content with my pair of SVS SB-2000 subwoofers - used 99% of the time for music, 1% for movies. I went on a little journey - purchased a pair of SVS PB-3000 subs. Way, way overkill in my 2 bedroom condominium. Ended up eating $360 on return/restocking fees at my local audio shop. I then found a 10" ported Monolith for $325.00 locally and sprung for it. Then, found a 2nd Monolith 10" Ported "Open Box" on the Monoprice site. I ended up purchasing the 2 Monolith subs for less than I sold my pair of SB-2000 subs for. To my ears, the pair of 10" subs puts out astounding bass, and while ported, I've found that it doesn't interfere with music, but sounds just beautiful. Additionally, if I want, I can plug the ports and lose a few Hz of extension. Best decision I ever made. The SVS SB-2000 subs weighed just 34 pounds, each. The Monolith is well built, well braced and weighs in at 72.5 Lbs., each.
