SVS PB13-Ultra worth it? - Page 3

The PB-13U is more than twice the size of the F113. Just run the math on the external dimensions.

Seen next to each other, the size difference is striking.

Not really, Dynamic EQ compensates for lower volume listening. It does this with a loudness contour/house curve effect but also redirecting the sound mix. But it has no effect if you are playing at reference level. So you still may want to add your own house curve on top of what Audyssey is doing. I have Dynamic EQ engaged all the time, but I still ended up boosting the levels a few dB to my preference.

Sub EQ HT's main benefit is EQ'ing two subs and the higher resolution of the filters

I have 4 PB Ultras (and 2 Pluses) in a 12x12x8 room with the ASEQ1 and it does not pound my chest unfortunately.

how do you fit 6 giant subs in a 12x12x8 room

Let's just say it's cozy.

The Ultras are the size of a beer fridge.

Square rooms are the worst but how does it not pound your chest? I have a hard time buying that.

Do the math, and include the grill for both units to be fair.

The SVS is approximately twice as large as the JL in cu. ft.

Something is way wrong with that.

You must have a pretty thick chest!


this must be you now I get it!!

The measurements do make them seem fairly close in size, but if you see them next to each other, the differential is pretty obvious.

27 x 20.5 x 22.5 = 12,454 cubic inches
19.25 x 16.5 x 19.625 = 6233 cubic inches

Looks like twice to me.

Here are pics I previously found.

Here they are a few years ago at my place. Quite the size difference...

Mike beat me to it ...

pbc, how would you compare your 1 diy av15 sub to your 1 pb13 sub.
thanks.

I'm fine with what Audyssey does for me.

I do engage Dynamic EQ.

Very strange. My dual PB13s can give me a chest pounding.

My single PB13-Ultra is able to provide some chest pounding. My sofa seems like having a small butt kicker in it too. Couldn't be happier. Still, I added a SB13-Plus to make it dual.

Just saw your post--so there you have it--two votes for the couch.


Maybe it is the chest part. I "only" have one PC-13U in my 10x12 room and I can't say I feel the bass in my chest--but I do feel the it. Mostly through my couch and across my shoulders and back--it is quite impressive to me but I suppose everyone's expectations are different.

The problem is: there is no official standard to what chest pounding is supposed to feel like. Maybe subwoofer reviews should include dolorimeter measurements from now on

In my room, not that much different from an output perspective (remember, my room is quite small and doesn't need much woof). Definitely much more low end, getting response below 10hz due to the sealed alignment. But a single PB13 was more than enough from 20hz up, and likely from 15hz for that matter as I get tons of room gain down low. I believe the AV drivers and the RMX-5050 amp gives me more headroom and power well beyond 100hz which is important as I now have Paradigm Signature S2 bookshelves crossed at 150hz and I'm not sure the single PB13 could have done as well. I haven't tried to do enough back and forths from an SQ perspective, and honestly don't recall thinking at first "wow that sounds so much better".

Having said that, when I took my PB13 to another AVS'rs (sputter1) place to do some listening to it vs the VTF-15H and another ported subwoofer built by Funky Waves (BillyP's) using the AV12H driver (or was it 15"?), ignoring the output differences (the FW box was much smaller), I do recall thinking that I preferred the sound of the FW box to the VTF and PB13. Not sure if that was because I was used to/accustomed to the sound of the aluminium driver of the AV sub vs paper on the VTF and the glass/cone composite (whatever) driver of the PB13, personal bias, or, heck, how the AV interacted in that particular room vs the other subs (or all of the above). I just recall thinking "hmm .. that sub sounds really sweet" with some of the upper bass passages (mainly recall it with the Open Range gun shut scene).
