      I run dual SB2000s and love them but have that addiction for deeper bass if my room allows it.

      The room is quite small,2.5m wide,5.5m long and 2.3m high.

      I had my mind set on the PB3000s but SVS recommend the PB2000s with the room not being that large.

      Has anybody changed from SB2000s to PB2000s? Do they go noticeably lower but retain that punch for movies? I am not bothered about the music side.

      Thanks

      Haven done the same upgrade last year I think you will be disappointed going to the pb2000.

      I have more output under 30hz but the sb definitely has more impact and dynamics in my room and it's a small room.

      The pb3000 has better midd bass due to the split voice coil but even at 3 grand for duals I'd consider looking at other brands.
      If you only going ported I'd check out arendal sub 1.5 sub 3, psa v1510 or any psa for that matter

      Your existing dual sealed subs with a 20-25hz lift should accomplish what you desire. Always preferred the sound from sealed tbh.

      Just make sure its located properly, even a few inches from ideal can make all the difference.

      On svs subs especially the 1000/2000 and old ultra series, if the gain is set to low it limits the dynamics of the sub.

      Basics of it are increase the gain by xdb on the subs the decrease it by the same amount in the avr. Sounds counter productive but it makes a huge difference.

      What is the gain set at currently

      No.I am willing to try it.Is that where you set the receiver sub volumes to the lowest setting and set the gain/volume on the actual subs to maximum?

      Receiver volume for both is set to -4db.Gain/volume on both subs is just over half.

      I have the rear sub at the opposite corner of the room but facing 90 degrees sideways along the rear wall rather than facing 180 degrees to the front sub.Both phase settings are zero.I was also going to experiment with phase settings on the rear sub.

      What avr are you using?

      If you go on YouTube and find the gain hack videos by subwoofer 101, I'm not sure how to post a link on here.

      His videos are a step by step guide.

      I watched the subwoofer 101 video where he sets the receiver sub volume as low as possible and the subwoofer gain to max.I quickly tried it this morning and bass you can hear and the low end bass that you feel was more present.I tried it briefly with Dunkirk and The Force Awakens (Falcon escape and Starkiller bass firing the weapon).I will experiment more with the phase and volume settings,maybe dial it back a little if I need to hit that sweet spot for controlled punch and also depth.I certainly do not feel the need for a ported subwoofer upgrade now.Thank you all for the advice so far.

      I am also surprised by how good the mid bass sound is.I was expecting the subs to dominate my other speakers but everything sounded clear and more balanced.Interesting.

      The only problem with the way he does it if u set the gain as low as it goes you carnt turn the subs down in the avr. Best way is to find a middle ground

      just to add...

      As a owner of SVS sub myself if your wanting deep bass and are willing to pay £3k for duals (PB-3000's) just do yourself a favour and go for the big enchilada and buy the SVS PB16 Ultra if you can accommodate the size which is not that far off the PB-3000, also i don't think you'll get the bass upgrade bug for a very long time if you went for the PB16 Ultra and it should be easier to integrate given that it uses digital DSP etc in other words you could set it up to be as tame or as brutal as you wanted;

      SVS PB-3000 = Cabinet Dimensions (with/ grille): 21.9” (H) 18.3” (W) 26” (D)

      SVS PB16 Ultra = Cabinet Dimensions (with grille): 25” (H) 21.7” (W) 30.9” (D)

      as you can see there is not much between them in terms of dimensions but there is in terms of the sheer onslaught of bass you would get from the PB16 Ultra.

      I would love a PB16 Ultra but have no room for it.I think it would be too much for the room size but here i am thinking of now upgrading to dual SB3000s.

      I'd highly recommend you check out psa 1510. Same price as the svs but the psa will blow it out of the water.

      The gain hack did produce more low end bass that you can feel during scenes where it has not been present befroe but i am not happy with the overall sound.It seems over the top at other times and not as tight in the mid range.I have dialed it back for now.I may buy a SPL meter and use REW to experiment

      I got a big boost as my gain was very low, under 9 o'clock. It's now at 12ish.

      You'll definitely get more output down low with the PB 2000/3000.

      Hmm, interesting. I was surprised that there is not in fact that much difference in size between the £1,549 PB-3000 and the top-of-the-range PB16-Ultra, which correctly has the reputation of being very big! However, there is a huge difference in weight, the PB-3000 is 82.2lbs (and that's pounds, not kilograms) and the PB16-Ultra is 174.5lbs, and costs £3,000. Also, can consider the in-between £2,249 PB-4000, which is quite close to the performance of the PB16-Ultra. The PB-4000 measures 23.4" x 20.5" x 30" and weighs 153.2 lbs.

      Your correct on the weight of the PB 16 Ultra she is a heavy girl, however in regards to the PB 4000 price wise there is not much in it around £700 saved, which is good if you needed other kit but if its a budget for just one thing then personally i would just go for the PB 16 Ultra as later down the road if you wanted to sell you would still recoup alot of your money back and more importantly i don't think you would ever need any more bass than what the PB 16 Ultra provides, meaning you would unlikely have to upgrade again (20+ years life expectancy) unless it broke down or you sold it.

      If it was me and money is know object and you only going svs I'd go dual PB 3000. They very close to the PB 4000 in deep bass but have much better midd/upper bass.

      How loud do you normally listen
