    Simple question :)

    In real terms, what would be the difference in performance between my 20-39+, and a PB12 Plus/2 (or Ultra 2)?

    Higher SPL and lower distortion thus increasing quality of sound. The PB-12 Plus/2 is one of the best real world subs around but according to the Secrets of Home Theater review the PB-12 Ultra/2 is reference quality.

    Are you thinking of treating yourself to a 38th Birthday present today - many happy returns by the way

    Nothing gets past you does it Ian :thumbsup:

    Part birthday present, and part upgrade. I have changed my front speakers, and would prefer a box sub which will now fit in my room better.

    I would prefer it to be an upgrade rather than a sideways move, so want to make sure I buy the right one. Without being able to see them, I need some advice :hiya:

    But the SVS box subs are huge would it go at the Front or Back?

    Thanks John :smashin:

    Have you seen the SVS cylinder in my room, it makes a Nautilus 804 look small. The 'problem' is 3 fold. Firstly, I want the sub away from the front to allow some movement for the 805's. You can see in the pictures on my site that there is no room to move anything.

    Secondly, and of no real importance, but the 805's are beautiful speakers, totally dwarved by the cylinder.

    Thirdly, and more important, is that I want a sub closer to the seating position, so you get more of the rumble through the chairs. I tried to put the 20-39 along the sidewall, but it always interfered with the 804's. With standmounters now, I could accomodate a box on the left hand side (and would make a useful table to put the pizza's/popcorn etc :laugh: )

    Wow. Good one.

    The Pb2+ and Ultra will defintately be better than your cylinder. Problem is I dont think you will be able to accomodate one between your speakers - it will have to go on the side I think. Great HC pics buy the way.

    The 805's are beautiful speakers and the sound is even better the SVS's do make excellent subs and if it were my money and could accomadate one i would definitly go for the PB12 Ultra/2 it would make for an awsome setup loads of deep deep BASS!!!!

    The idea of getting the sub would be to stick it against the side wall to bring it closer to the seating position (see my post above).

    There seems to be a huge gap in cost between the Ultra 2 and the Plus 2, as well as the plus having a slightly smaller cabinet, so that may end up being the choice. Its a tiny room (8ft x 15ft approx), so the Ultra may just be a little overkill?

    Does anyone have/heard either of these yet?

    Plus 2 in wood finish would be my choice. Yes, the ultra 2 is overkill, but then so is the plus 2. I'm sure smurfin will disagree :)

    Performance wise though, in that room, going from a cyl + to box + 2, I doubt there would be any difference in sound at all.

    lol... sounds like you may want to buy my dd15 off me when i realise that its completely ott for me chris :)

    on topic i'd have to agree that the pb12 plus 2 would be the best price/performance ratio for you if are looking to upgrade

    I'm pretty sure you would notice an improvement in sound quality if your speakers could breathe more easily. My 16-46 completely modifed the sound of my Mission 753Fs. Simply because it was sitting next to the left one. The left speaker being nearer the corner of my 30 feet long room. Moving it to just inside the right speaker made a huge difference in the measured frequency response and tightened the bass dramatically.

    Now you've moved on to standmount speakers. (probably an excellent idea given the dimensions of your cinema) I'd try laying your cylinder on its side on the floor. Just as an experiment to give more air around your speakers. I think you'll notice an immediate difference in bass quality. The cylinders work just as well on their sides according to Tom SVS. You could even use it as a foot rest while perched in your gorgeous chairs. But what a way to treat an SVS! :devil:

    Are you winding me up re laying it on its side? :)

    If its genuine, I'll give it a go and see what happens. Where did you read about Toms comments?

    It was discussed in a private communication with Tom V prior to purchase of my own (potential) foot rest.

    The idea being to hide the cylinder behind the TV and speakers where there was plenty of room in my attic listening room.

    In the event it wasn't necessary. My wife didn't object quite as strongly as anticipated to the 16-46 when it arrived. :rolleyes:

    You'll still notice it if you play movies around the -5db mark (imho).

    Urban T - for the money you will get back on you're SVS and add the rest it wouldn't be much more to buy a ASW850.
    When i sold my SVS i more or less got the same money back as what i paid for it!!

    Lets consider that.

    SVS = +/- £500 - £2000 B&W = £1500 shortfall = much much more :)

    I calculated a total cost of a PB12/2 to be around £1000/£1200, which is where my ideal limit sits.

    Chris - If you want it to look good next to your Sigs then the wood finish SVS is the one to go for. The black looks like a monster - before the SVS crew slaps me down Id like to point out that it performs very well regardless :rolleyes:

    You know it :D I'll never forget playing Cafe Del Mar in my old listening room at -0db in stereo, with the PB-2 Plus. Made my jaw hit the floor :D (still looked like the back end of a bus but it doesn't matter in a dedicated room now, does it?:) )

    The SVS 25-31 PC+ may be under threat, as my better half has plans of doubling the sub up as a piece of furniture, I know criminal ! That leads me to look at the SVS boxes, and I wondered what in their range would be the equivalent of the 25-31 PC+ ?
