My upgrade path. Would like input.

I have an 8200 ft^3 space in an open floor plan with vaulted ceilings. I started with a 20-39+ placed near (6') the listening position. It did very well on the SPL meter for the LP, but it could not fill the whole space. Though I care more about the sound at the LP because I don't move around while watching movies. I traded in the + for a +/2. Much better, but it still can't pressurize this large space. But I am very happy with it. It is also placed near field because I have no other spot to put it. I have a large space volume wise, but not much floor space. Had the NSD/2 been available, I probably would have tried it.


There is another new member that has a large open space that didn't have the budget for a large SVS. He went with the PB10. I got PMs from him on how overwhelmed he was by this sub. About a week later, he PMed me that he had found a different location for the 10 and had purchased an NSD/2. So it didn't take long for him to get bit by the big boom effects he had never experienced before. The point of this is, he was very happy with the PB10, but once you get a sense of what it will do, you want even more.


I don't know what it is, but there is something about the power you sense from the dual driver boxes. I'm sure you get that from multiple subs as well. I am pretty sure two PB10s can produce a good level of force. There are some hints that a PB10-NSD will come out soon, but I can't say when.

I haven't heard the Ultra. I am slowly introducing myself to other members in Sacramento (those I haven't already pissed off) to get exposure to other subs. I am working on something to demo an Hsu HO, Rocket ULF-12, and maybe an Earthquake MKV-15. When I find an Ultra, I will try to demo that too. I decided on hearing these things in OP houses as I have been VERY disappointed by the demos at stores and installer shops. They have just been a waste of time. Instead of misjudging subs from poor demos, I figured members would give a better show of what's available.


I am very happy with my +/2, but you got to hear others to know what you have or don't have. I'm not trying to second guess myself, just trying to get some exposure.


The only second guessing I am doing is whether I should have gotten a second 20-39 instead of the +/2. The advantage of the cylinders is you can actually move them by yourself. Some people don't like the looks of the black water heaters, but both my wife and I did.


I started out looking for a $500 sub. I thought that was a lot to spend on a speaker. After researching, I bumped it to $800. The PC+ was $900 delivered, so I bumped again. After that, it was only $300 more for the +/2 (another reason why I didn't go dual 20-39 was the $1800 price). If the Ultra/2 was a little closer to the +/2 (instead $800 more), I probably would have gone that way.

Hi, I was the guy that Ransac was referring to who purchased the PB10 and a week later purchased the NSD/2.


I purchased the PB10 (instead of a larger one) not so much because of budget restrictions, but because $500 was about the max that I thought I wanted to spend on a subwoofer. My theater is well over 5000 cubic feet, and members much wiser than me recommended a larger sub to be able to really fill the room. My problem was that I had not experienced a quality subwoofer in a home theater. I did not realize how much benefit to my viewing experience a quality sub would provide...


The PB10 is terrific, and has clean, deep, strong output. It has changed (positively) movie watching for me entirely. It also adds so much to music, I cannot believe it. I never would have thought I would listen to music on it, but I do.


Unfortunately, for the large room, it just isn't enough. It really has to work to provide bass close to what I really want, and it just doesn't fill the room as nicely as I would hope for. That's where the NSD/2 will come in. It's in shipment right now, and I can't wait to get it in my theater.


My point of this post is to stress the importance of considering your room size and the bass that you really want. I watch movies 99% of the time, and so STRONG bass response during movies is my primary importance. You may want to consider upping the budget a bit and getting what you really want to start with. You may find it worth it.


Although, I'm happy with my route, because I will have two theaters in my house with excellent bass.
