Seeking to Upgrade Subwoofer from SVS SB2000


My system consists of the following:

Martin Logan 11A Impressions loud speakers, Bryston 4B3 cubed amplifier, Rogue Audio Tube preamp, Lumin U2 mini streamer with LHY power supply, Chord Qutest DAC with S Booster Power supply.  I have 2 SVS subwoofers  model SB-1000, each retailing for $350.00. My upgrade sub budget for 2 subs are $1000.00 total. The Martin Logan is adjusted properly and I find the bass a bit weak. The current 2 subs help, but I would like to do better.  Thank you.

My upgrade sub budget for 2 subs are $1000.00 total. The Martin Logan is adjusted properly and I find the bass a bit weak. The current 2 subs help, but I would like to do better.

Budget is too weak for a sub upgrade. You can’t do any better than your current SB2000s with such a budget (i.e., there’s nothing wrong with your subs).

I would wager that it has everything to with incorrect sub placement and incorrect integration with your mains.....because those 2 subs should give you enough bass to hit the brown-note (better than miralax) if you cranked it all the way up.

Without knowing anything about your room dimensions and whether you have a measurement mic or not....try as follows.

If you have them on the front stage, move them on both side walls behind your listening position (not too far behind). It should cancel out some key modal nulls and give you a feeling of envelopment. You probably have the crossover setting very low because you saw the printed frequency response spec from the manufacturer perhaps. Turn the crossover up fairly high, 100 hz or so (you won’t localize a whole lot with the dual subs in such a position). Last but not the least, fine tune that phase knob. Last i recall, SVS gave you a continuously variable rotary phase knob, not a rudimentary 0/180 flip switch like Rel or something...

 

My room size is 12 x 18.

I was considering SVS SB 4000 which is on sale for $1299.00 each.

I would buy 2, get a $200.00 discount for the second. I am very close to my $2000.00 budget.   

Thank you. 

This could be your luck day. I had 2 SVS subs tried all kinds of trick tweaks to integrate them. Go to VeraFi Audio >speakers as subwoofers>Vanguard Caldera 12" @ $399. Extremely well built and designed. Lots of great products at down to earth prices

@deep_333 +1 The OP can buy two more SB-1000 subs and place them behind him as you suggest. This is the sub swarm concept. Spending $2K is a waste of money when the OP already has a capable pair of subs. A swarm of four or six subs will give smoother and more enveloping bass.
