PB"13" = 13" drivers now?

One typo: The new Bash amp is 750W, not 950W.

12" => 6" r => 113 sq in
13.5" => 6.75" r => 143 sq in

About a 25% increase. Hmmm... If I now get an in-room response down to 11 Hz with a PB12-Ultra/2, I wonder how a PB13-Ultra or Ultra/2 would do. Posted Image

Kevin, you have to do driver surface areas using the part that moves only: If we estimate effective piston diameters of 10.5" for the TV-12 and 12" for the U-13 we have (6.00 / 5.25) ^2 = 1.306, or roughly a 30% increase in effective surface area.

However, below the cabinet tuning point the output comes from the ports. Tom has not said anything yet about the porting of the Dual driver cabinets which are still in development, but he has said this in an excerpt from a post on HomeTheaterSpot concerning the porting of the new Ultra single driver cabinets:


"...we've designed all new custom tooling for the port tubing, inner flares, outer flares, and elbows to further increase port flow. Going from 3" to 3.5" doesn't sound like much...but it represents >35% more sectional area. When you factor in the new tubing, elbow, inner flare and outer flare a good estimate for the increased port flow would be around 40%. (not an insignificant amount by any measure..Posted Image

Now, could it be argued that the new designs would perform a little better <15hz if we made it twice as large(so it could have more porting area in 10hz mode)?...sure. But there are always aesthetic/performance trade offs to consider. The new designs are already large and heavy...increasing both of these fundamental aspects significantly to increase the performance in an extremely narrow bandwidth(<15hz) that had very, very little content wasn't a trade off I was willing to make.

Put a new PB13Ultra in 15hz mode, experiment a little with the PEQ and room compensation controls...and you should be able to generate a reasonable flat response curve down to 10-12hz in most rooms."

Is there any preliminary information with regards to initial pricing of the PB-13 sub?

Not yet, Bryan. Tom has said he expects to have pricing firmed up on the single driver cabinets within 60 days, with pre-orders hopefully starting in late April or May.

EDIT: My diminished capacity is giving Tom and his suppliers an extra month!

Actually he said he's guessing late March or April Posted Image

Hmmm..... wonder if I can score a deal on a leftover PBUltra is cherry ?
"Did you know that more people are murdered at 92 degrees Fahrenheit than any other temperature? I read an article once. Lower temperatures, people are easy-going, over 92 and it's too hot to move, but just 92, people get irritable."

Now there's a thought. Posted Image (I have an Ultra/2, but I keep toying with the idea of swapping that out for 2 Ultras.) But then if the past is any indication of the future, SVS usually offers intro deals for new products too. Posted Image
