Many thanks to this community that has such a wealth of knowledge and shares it so generously! Long time lurker, first time poster here, so please be gentle.
Merlin on SVS website appears to recommend PB1000 or SB1000 for my Kanto Yumi bookshelf speakers, I originally considered both but then realized that PB1000 is too big (dimension-wise), so I had to rule it out and look at SB1000 and SB2000 instead.
My intended use for the sub is to augment the Yumi speakers in my computer system and I will mainly use it for gaming, some movies from Netflix and such (not Bluray, so no LFE channel) and some music (mp3's via iTunes and Spotify). I've been using a Klipsch ProMedia 4.1 system for my computer audio for probably 14 years or so, but recently the Klipsch sub blew the foam on one of the drivers (damn that Oblivion bass-heavy soundtrack!), so after I repair it I may exile the Klipsch to my office at work. I wasn't a huge fan of the Klipsch ProMedia actually, it sounds harsh, fatiguing and strained to me in the mid frequencies at higher power settings, so they gotta go. Besides, it's so much fun diving head down into research and tapping into the collective wisdom of like-minded audiophiles
I live in a condo so I don't need earth-shattering power, but I want to be able to clearly hear and to some extent feel the bass without having the turn up the sub's power way up. The sub would be placed in my computer room/den which is really tiny (about 2 meters by 3 meters). I am not certain, however, that SB1000's relatively quicker low roll-off (compared to SB2000) is ideal here. I also think that SB2000 is supposed to reach way lower than SB1000 and sound more impactful while doing so. Even though I don't want to test the structural integrity of my condo, I want to be able to clearly hear and feel the lows without having to turn up output settings.
There's another consideration - I may eventually upgrade my TV viewing experience to a proper Home Theatre and move the sub to my living room (approximately 7 by 4 meters, listening position on the couch is about 3 meters away from where the home theater is, and the back wall is right behind the couch). The speakers in the living room are some old but great PSB monitors which are probably at least 50W each, unfortunately I don't have the exact model/power info. They are driven by a very old Sony AVR, but the sub would need to be connected at speaker level since the receiver doesn't have a dedicated subwoofer out. Having read how some reviewers found SB1000 lacking power in Home Theatre setup in rooms that size and thinking that it's better to have lower frequency extension as well as more power should I need it - I began looking at SB2000 (PB2000 is just too big). If moved to the Home Theatre setup, the sub would be used primarily for TV and streaming movies and very rarely for music.
I realize that there's one sub that would be perfect for all these uses, so I am trying to get the next best thing - something that would work reasonably well in both applications, with both sets of speakers. I could of course, just get a SB1000 for the computer den now and and a SB2000 for the living room later but if that can be avoided by using one sub I'd much rather do that.
So I have to choose between the two SB subs because of their smaller physical design. I am ready to pull the trigger from the Canadian SVS dealer just need to figure out what I should get. Should I still be OK with SB1000? I would be happy to save a few hundred (who wouldn't) but would be just as happy to pay more for the SB2000 if that is a better, more universal and future-proof solution for me. Or should I get the SB1000 for the computer den now and an SB2000 for home theater later? I even looked at PB13 but that clearly is too big and would probably not be a great match for my relatively puny Kanto Yumi computer speakers.
Any thoughts/advice will be greatly appreciated!
