Ok so the diff between the two is that you can tune the 20-39 down to 20hz. Is this worth the extra 50 bucks...oh yeah and it is 39" high vs 32.5".
The problem is our room is about 2800 cubic feet and I can only afford the PCi models.I just bought a 25-31PCi (tuned to 22Hz) and I have a 6000+ sq ft room. This sub absolutely ROCKS! Bass is clean, tight, and hits very hard. If I were you, I wouldn't be too worried about getting a 25-31PCi. It's was more sub than I expected for $589 delivered.

Tom's recommendation was good enough for me (... he is the SVS mastermind designer ...) and as my 25-31PCi vs. SW15 Review indicates, ... I'm was and PRESENTLY one very "HAPPY"SVS Powered Cylinder Series Response Comparison Chart said:Quote:
... if the 25-31 extends down to about 21, what is then the advantage of the other lines of subs since most people can't hear below 20 anyway?My guess so they can stop their pace-makers!!Seriously, from what I understand, the Ultra & 16-46PCi will send an Organ (Mighty Wurlitzer w/32-foot long tube to reproduce the 32 Hz note) fan into sub-sonic felt bliss!! As much as I like some Organ based music (2001 Movie Score - Richard Strauss' Thus Spake Zarathustra- in my Delos DVD Space Spectacular DVD), my main interest was HT and Jazz music - mostly keyboard artist like David Grusin, David Benoit, Joe Sample, Diana Krall, etc. So if your a Organ music fan, it's the Ultra or 16-46PCi for you!!!
Very few DVD's have LFE encoded material below 20 Hz, and if it does, it's about 2 or 3 total seconds in the entire 2 hour movie. The majority if not all DD/DTS LFE effects is within in the 20-36hz range.
Once your HT setup is properly REFERENCE Calibrated, the SVS 25-31PCi LFE sub-sonic power to move air (pant leg), couch, floor, walls and cleanly reproduce those lower frequency without directing attention to itself is just glorious!! The entire HT setup just blends seamlessly together from 20Hz - 20 kHz overall sound spectrum, pulling you into the blockbuster movie or 2-channel music presentation! Yes - it is just 'glorious and with much honor' (to quote a well-known Klingon Worf! - Nemesis released this Friday)!
Hope this helps,
...do you have an equalizer with your SVS... ?Nope! Just REF Calibrated using Video Essentials dedicated LFE test tone = 81 dB AVG (where the highest swing of the RS SPL Meter needle just touches 83 dB & lowest swing touches 79 dB). Rest of my speakers = 75 dB
I own the Delos DVD Spectacular and it includes 20Hz - 20 kHz sweep for each (5.1) channel and playing those test tones reveals that the blend from the lowest frequency up thru the Yamaha fixed 90 Hz x-over is very smooth.
Just have to convince the woman on this beast...Well, ... 'may the force be with you!'
Even thought the SVS 25-31PCi is the smaller cylinder sub vs. the SVS 20-39PCi, most wifes comments are ...
... when the see the SVS 25-31PCi!!!
Come to think of it, ... when UPS carefully place my SVS Box on my porch, ... I had the same reaction, ... then when I told the UPS driver what was inside the box, ... he had the same above reaction!!!
