SVS Ultra-13 owners- 20hz,15hz,10hz or sealed?

danz1906

Hi guys,

Which mode do you use? It seems like most people use the 20hz or 15hz
the most. Those with Duals sometimes use the sealed mode.

Has anyone used the 10hz mode???

I really think sealed mode has little advantage over 15Hz mode for both HT and music with Dual PB13s. I found 15Hz mode for just one or two PB13s to be optimal.

So, Xmas comes early for you this year?

I forgot. Sub management system like SMS-1 or SVS AS-EQ1 is a must. It makes a huge difference.

Definitely, I love the SMS-1 with my dual PB12/plus 2's. Dual Ultras would be fun, but sadly shipping kills the deal so I can't join you guys club.

Did you use the Sub mgmt systems with a single Ultra-13?
Or is it just a must with Duals???

Or REW and a BFD if you need more than one filter.

I use 20hz and am flat to 18hz

You sure could see a lot of advantage using SMS-1 or AS-EQ1 with Single sub setup. It's room correction features works great for either single or dual or more subs setup.

Yes! Absolutely.

For HT, I would not plug my subs and limit their output, especially when the sub already goes to 20hz and probably digs deeper due to room gain. The plugging IMO is more disadvantageous especially when the headroom is limited leading to port chuffing. With that said, if you have plenty of headroom already you can play around with the sealed settings to get the desired sound and freq curve.

Of course you have to play around with RTA and REW to see if you get a smoother curve from plugging one of the parts. However, if it's strictly more music oriented setup, plugging your ports isn't as detrimental.

You underestimated the idea of feeling real than hearing. The usable infrasonics frequencies will make HT feel more realistic than hearing it.

If one owns multiple subs, the concerns is more about the realistic sound quality and feeling the theater experience real than the output alone. All the more reason to try out the infrasonic if you have multiple subs.

IMO, one should really find out the differences between 20Hz, 15Hz, 10Hz or sealed modes in the room if the very loud bass is not your aim.

I will admit, I may be underestimating infrasonics, but I would prioritize headroom over infrasonics and that was the point i was trying to communicate. More headroom, means the sub will play cleaner and with less distortion. However, if there is plenty of headroom already, and the subwoofer is not being taxed, playing around with the other options seems better suited.

With that being said, most of the "thump" and "slam" is from the mid-bass which do not occur below 20hz. There are tangible benefits being had from running with ports such as infrasonics as megasat mentioned, however, i would never plug my sub when headroom is not plentiful and which could lead to "port chuffing." Most of these assumptions are of course, with HT, and with music, there are different priorities.

This can be easily experimented with and only you can choose your own setting, it's a matter of playing with it.

I'm going to tryout the 10hz and seal modes today on Movies and Music.

I guess you shipped the original subs to Japan yourself? Too bad, SVS discounted the Ultras 10% for black friday and even threw in a free 8M cable before they resumed shipping this month. The discounts more than made up for the standard shipping charge.

I had a Snow Day today due to the Blizzard of 2011, so I tried out the
10hhz mode. The 10hz mode provided tight bass that went deep, but not
as much output as the 20hz. Although 10hz mode was good, I still prefer
the 15hz and 20hz better. Next Off-day Sealed mode, I love this Sub

I finally got around to the Seal mode on the Ultra-13. In the Seal mode on
Music the Ultra-13 is almost as good as the JL F113 subwoofer. The Bass was
super tight and fast,sounding Very good with Music! With Movies the seal mode
didn't have the Slam or output that the 15hz or 20hz mode. In a small room the
seal mode would work just fine, or Dual Ultra-13 in seal mode in a Larger room.

I'm using dual pcu 13's in 20 hz tune in a 2 ch rig. This way gives me incredible bass without any driver stress at all. I also have a pair of Paradigm subs which at times I use in conjunction with the ultras.:eek:

Just some dbx pro audio gear.

Advantage

15 hz seems to be the best combination for HT and music for me.

Agreed the 15hz is the best all around mode, but I'm starting to prefer the
10hz mode in my room. It seems a lil tighter and deeper, but not by much.
It's great that the Ultra-13 is so flexible!

danz1906

10hhz still seems to be King in my Room, now if I could afford to get another
Ultra-13 that would be idea:biggrin:

Advantage

Hmmm, now you have me thinking. I should give the 10hz mode a longer try. Having dual Ultra's would be awesome, although I really don't have that kind of space.

Do you guys see any advantage to having a second Ultra in an open room adjacent to the family H/T room? The second sub would not be in the primarily listening room but next to the bar in an adjacent opening? Any ideas / thoughts would be appreciated.

Dual subwoofer even out the sound and in Most cases are better than a single sub.
