Well my borrowed spl meter has arrived all the way from Scotland, (a big thankyou to morg for taking the time and trouble to send it by the way) but I have not had time to calibarate yet.
I have however connected the svs to my nad 2 channel amp using the subs high level inputs to try it with music....and all I can say is wow! wow! wow!
I set the sub up with one port open and the subsonic filter set to 16hz, enabled the sub crossover and set it quite high at 70hz, (my main speakers are little mission 780se's and their lowest declared hz being 65hz.) I thought I would leave the volume as it was and be prepared to adjust it and the crossover as neccessary.
First I tried out Soul II Soul "Club Classics Volume 1" and sat down thinking I would be up and down tweaking and skimming through tracks as I tried for a good sound in the room. No way, I just sat with the biggest grin on my face for 50 minutes hearing that album for the first time ever! well thats what it was like . No boom, no bang just every instrument spaced and placed and sharp as a pin.
Next up India Arie "Acoustic Soul", a brilliantly produced album with some real deep bass that I knew needed some special treatment. I was not disappointed, I can't get over how without making any adjustments at all, no matter how loud the volume went in my 26 foot L shaped room, the sound was rich warm and enveloping, no hint of boom or thud, the pb2+ can start and stop in a microsecond.
Then I tried Groove Armada and "Vertigo" an album with some really low frequencies that I "thought" I had much enjoyed for the last few years. Pah!, I had never heard that album before in my life, the svs revealed those deep deep sounds that were there all the time just waiting to be dug out of the mud of my previous setup. The important thing to emphasise is the way the sub makes the space between the instruments seem like they are in the room, its like they are being painted in the air in front of you. Red Hot Chilli Peppers, Sizzla. Peter Gabriel, Foo Fighters..
I could go on but I have to find the time to go through all my music collection and really start hearing it for the first time!
Having heard the pb2+ I can honestly say that I would have paid the asking price for this sub just to use for music alone, never mind the joys of home cinema I still have to come once I have it set up right. Anyone who enjoys music be it it vinyl, cd, sacd, dvda, whatever will love this sub, Tom and Erik have done a fantastic job bringing this product to the market place, I could kiss them.
If you have thought about going the svs route and have any doubts at all then I can assure you, the hundreds of rave reviews are not wrong, these are greats subs and the pb2+ plus is absolutely amazing! One very happy bunny here!!
