post #91 of 15654
Thanks for the advice guys.. Going to try spinning it with some low Hz sweeps this afternoon after the wife leaves.. He he
post #92 of 15654
If you have pets, make sure they are not in the room. They seem to hate the high level tone sweeps for the subs.

Thread Starter 
Just did a routine calibration of my speaker levels, and found that I had to knock my LFE pre-out on my AVR down from -3.0 db to -5.0 db. My PB Plus/2 has been up and running a couple months now. I initially set it up to run about 5.0 db hot over the rest of my speakers, and I guess over the last couple months its broken in quite a bit. Just an FYI for those of you who haven't calibrated in a while. I expected it to brake in, just not that significantly.
post #94 of 15654
i actually called svs asking about brake in period. THey told me there isnt one, just to run the sub a little quiter than normal untill you get adjusted to it...
post #95 of 15654
i love my 20-39 pci fantastic value, best subs in the business, but now looking for bigger and deeper i will probably buy and ultra. can't wait to try one of those bad boys out
post #96 of 15654
I have one of those Kill-A-Watt deals to measure power consumption and measured my SVS sub at 18 watts a normal levels and ~26 watts at full tilt reference levels...double-checked it even. I thought something was wrong with the meter, but my receiver was pulling 76-125 watts, my PC 150 watts at idle, Sony laptop - 47 watts so I think the meter is ok. Could the SVS be this efficient?
post #97 of 15654
what kind of material was playing through the sub when you took the measurements?
post #98 of 15654
Keep in mind, that meter is reading consumption, and not amplifier output. Also keep in mind that is a class D amp, which doesn't generate a lot of heat. They run 90% efficient, where a class A/B amp as in your receiver is roughly 50% efficient.

A large, ported box should be extremely efficient, espeically with a BASH amp.

Try your meter on a hair dryer on high, an iron heated up, and toaster oven heated up. Also try it on a simple lamp with a 100 watt bulb.

Report back if you don't mind.
post #99 of 15654
I played Tupac Shakur "Hail Mary" lots of ~20Hz bass. I totally forgot about the benefits of a BASH amp so I guess these result really aren't a surprise.

Those are all good suggestions to test, but I borrowed the Kill-A-Watt from a buddy and already gave it back so no more testing. The box did say 0.2% accuracy. I tried it on my brother's color laser printer while printing: 850 watts max. My 50" LG plasma takes 49 watts turned off (!) and 450 watts while on.

Its not watts you want to be concerned about, its amps that you want to pay attention to.

No matter how efficient the amp is, it can't output more power than it takes in!

PB2+ owner here. Just upgraded my drivers to the 12.3, wow!!! If you have not upgraded, go for it....Art????????????

Here is my gear.

the little trash can .... is that the pci model?
post #104 of 15654
LOL, its for the fireplace ashes.
post #105 of 15654
Upon further reading, it seems the low wattage used by your subwoofer (and receiver) at reference levels is probably accurate and is due to the exponential nature of sound. With sound, the power has an exponential relationship to the perceived volume, such that the difference between 2 watts and 20 watts is perceived as the same as 20 watts vs. 200 watts.

Maybe your system only has capacity for a 20% increase in perceived volume before you max it, but that last 20% would require a multiple of the power that you were using at reference levels.

There's a store near me which sells fireplace equipment, and they have a sign outside and it says "We Kick Ash".
post #107 of 15654
I was thinking more of a chunder bucket
post #108 of 15654
I probably could have turned it up louder, but it was already rattling the walls. The 20x14 room gave out before the sub (corner loaded) so maybe I wasn't maxing it out as I thought, explaining the low consumption. I just bought a kill-a-watt of my own from ebay so now I can test at my own pace.
post #109 of 15654
What you are reading is the RMS wattage use. Since an audio signal, especially to a sub, is more not there than it is there, your average power useage is very low. If you want to see how much it can draw, run a 20Hz sine wave at full volume. Then you should see power consumption close to the full capability of the amp

Kipp,
That sub blends in very nicely. No wires either, near-field well done.
Do you use it as an end-table for drinks and stuff?
post #111 of 15654
Kipp, I noticed you have your center on the floor under your screen. How's the vocals from that set-up?

Thanks. My goal was an uncluttered appearance. I do not use it for anything other than a sub. It hides nice behind the couch considering its size.

Actually very well. That is a Klipsch RC-7. I actually plan on mounting it to the wall but have been too busy to get to that. Soon.

Wouldn't they be directly related, as long as the comparisons are done at the same voltage?

How does SVS handle the upgrade and how much is it? Thanks for the info!
post #116 of 15654
It's $169 per woofer, and you have to switch out the drivers yourself. All you should need is a drill with a philips screwdriver bit, or even a hand screwdriver if you are very patient.
post #117 of 15654
I don't know if they still do, but in the beginning, SVS even provided the bit.
post #118 of 15654
Well ladies...it's official...the Ultra is gone!!





Ok, time to look into a replacement!!! will the following contenders please rise:





muahahahahhahahahahah







muahahahahhahahahahah










muahahahahhahahahahah










MUAHAHAHAHAHAHAHHAHAHAHHAHHA

ps- see that little nice SVS sign on the wall? person with the biggest bid gets it!! LOL

A dark shadow falls over Shervin's theater room as he laughs with diabolical insanity. The walls shake with fierce intensity as the SVS placard in the background falls to the ground.
