Scrappydue Posted November 9, 2014 Share Posted November 9, 2014 i have owned two of the pb-13 ultras. and why they are fantastic subs i do not think they are worth their asking price with other options out there. you have a HUGE room and would easily need two of those and even then would still be pushing them hard at reference volumes. can you stretch your budget? try looking into maybe a used or a new JTR orbit shifter or JTR S2. i would say for the extra 1000 bucks an S2 would Equal 3 svs ultras and the orbit shifter would equal probably 5 of them. if i were you i would go with the orbit shifter if you can fit it. they have an unreal amount of output which you NEED bad in that huge room Quote Link to comment Share on other sites More sharing options...
willland Posted November 9, 2014 Share Posted November 9, 2014 my hole upstairs Is900 square feet ( open concept) How much of the 900ft2(7200ft3 +) is actual HT/entertainment area? Only about 2500ft3 of my 6000ft3 open family room/nook/kitchen is entertainment seating area. My four subs are more than enough to create a low frequency infused HT experience. Now if I was to utilize more of the space for HT, then I might have to rethink some things. If you are trying to fill that 7200ft3+ space with real impact, then a couple of DIY 18's may be in order.

derrickdj1 Posted November 9, 2014 Share Posted November 9, 2014 (edited) On many forums and in general people say that the sub will see the whole space but, that is not entirely true as Bill pointed out. Proximity will play a big part in the tactile feel department. Particle velocity and distance can make a big difference. Nearfield placement Is an excellent choice. The vented subs have a port and the speaker cone producing particle velocity which is why they perform better down to 15 Hz than most sealed system. The vented subs have a 24 db roll-off at tuning and output drops off fast. A sealed system with a 12 db roll-off combined with room gain in under 2400 cuft. space will have much more output below 15 Hz. For the OP room size, vented are the way to go unless she wants 2-3 times the number of sealed units.

Kelly McAloney Posted November 9, 2014 Author Share Posted November 9, 2014 Probly about 1/3 of that is ht, and after doing some measurement , the whole space is actually closer to 700 Quote Link to comment Share on other sites More sharing options...

Paducah Home Theater Posted November 9, 2014 Share Posted November 9, 2014 How does the pb13 ultra compare against velodyne hgs18? Get you one of those Digital Drive 18's that Velodyne makes. Quote Link to comment Share on other sites More sharing options...
jason str Posted November 9, 2014 Share Posted November 9, 2014 One THT horn loaded subwoofer will offer better sound and leave your structure begging for mercy, plus it costs less than many of the others mentioned here. Horns offer lower distortion resulting in a much cleaner sound. Quote Link to comment Share on other sites More sharing options...

derrickdj1 Posted November 10, 2014 Share Posted November 10, 2014 If the mains are heritage a horn sub is a better mate. Otherwise, two of the R-115's, or the subs in post #13 will do the job. The room will sound better with at least two subs. Quote Link to comment Share on other sites More sharing options...

The room will sound better with at least two subs. Why would it matter if the mains are Heritige or not ? I agree two subs will help smooth out room modes but i would take one good subwoofer over two or even three average ones any day of the week. If you want the job done any subwoofer will suffice, if you want the best sound buy a better sounding product. 1 Quote Link to comment Share on other sites More sharing options...

But I feel the same way. I'd take a single more powerful sub vs two mediocre ones. That is why I suggested a horn in that big if a room. Either diy horn or JTR orbit shifter sounds like the way to go. Quote Link to comment Share on other sites More sharing options...

Mystery Posted November 10, 2014 Share Posted November 10, 2014 (edited) Multiple subs can eliminate dead spots and easier to setup than trying to get even frequency throughout the room with one sub. However, they should be at similar level subs. Multiple crappy subs will sound crappy compared to one decent sub.

If you want the job done any subwoofer will suffice, if you want the best sound buy a better sounding product. Tight bass is what people like about horn sub and all horn systems. It is a function of compression thur the narrow throat. Horn sub in the old days were limited in the under 30 Hz area partly due to this compression. That no longer exist, Danley comes to mind. Horn boxes are large in comparison to most marketed direct radiator subs. Direct radiator today have great xmax and the drivers can take a lot of power which makes them great for HT. In general they are not has efficient. One is not better that the other, just personal preference. With the advent of HT the manufacturing of direct radiator took off. My experience with horn subs is very limited and feel free to make additional comments. Quote Link to comment Share on other sites More sharing options...

But hey, what do they know. funny when i bought from them they recommended one pb-13 ultra over two of their lesser subs. so id say they are all typical salesman, and they have their own opinion. and id also take two PORTED 2000's over the SEALED 13 ultra. sure thats a no brainer. now you can read back to my other posts where i told the OP that the pb-13 ultra isn't gonna do it in that large of a room. and even a pair of them would struggle. which is why i recommended a horn subwoofer of some sort. and jason said they very same thing. a lot of these guys on here have been doing horn loaded subs for a while. id listen to them when it came time to get a sub for a large space any day over a salesman at svs. Quote Link to comment Share on other sites More sharing options...
