ok here is a max spl measure taken at 0 on my yamaha avr. I also performed a 15hz sine wav test... turned the avr up to +5 and gained another 2db from this test. I have not aquired a eq device yet to tame the peak obviously. Here is the thing, I believe the subs still have more left in them. Whenever i go past 0 on the yamaha it introduces some distortion no matter what the gain is set at on the subs? I could probably turn the gain up more but I dont want to hurt these beasts. As you can see in the test, Im hitting 113db @15hz with no audible distortion other than the house sounds like its falling apart. So yea these subs will do around 115db in the 15-20hz range. 2400^3 room with a 6FT opening in the left side. cool.gif

Thanks! Honestly tho, how much output does one need? I don't intend to listen at these levels, its just nice to know I have plenty of head room. Next up, a EQ setup to flatten that peak.

OOPs, I replied to the same post but in the wrong thread(PSA thread). Again, did you measure THD and what gear are you using? You are also nearfield so telling people what they can hit is not accurate. It depends on the room and distance.

You are not talking about spl alone, you are talking about different frequencies and spls. If the responses are truly the same with no compression and the THD profile are the same then yes, 120 dBs is still 120 dBs.

I am 6ft from each sub and the subs are 3-3.5 meters apart. Even If the subs were 15ft away I would only be down 1-2db from my LP. I have a Dayton umm-6 mic and REW software. I didn't tell anybody they could hit this output, I was simply sharing my results.


Here is what Tom told me to expect:

2 subs = 105...outside at 2m.

Put up a virtual corner outside just to realize typical in room boundary gain and you'll see a level increase of 8-10dB(assuming construction similar to typical North American rooms.

So that is 113-115dB / 16hz / outside at 2m with distortion limits still in place.

You still have to factor in "room gain"----also referred to as "pressure vessel effect". Here's one take on this ( http://www.nousaine.com/pdfs/Cabin%20Gain.pdf )

This is tough to predict as there are several key variables that are hard to quantify. Using a generic room example...say 2500 cu-ft with one modest opening (5ft) to other areas of the home...you can look for something in the 4-10dB range around 16hz. Pick out something like 7dB and that would probably be okay. So now the max is 120 or so.

If the subs are separated subtract a dB or 2. If the subs are not corner loaded(but against one good wall) that would also drop the levels slightly. If the subs are (on average) much further than say 3 meters or so from the seating/mic position....the max levels would begin to drop a little. Overall I'd say 115dB/16hz in most rooms shouldn't be a major problem. If the room was say 6000 cu-ft and the subs were say 4 meters away....now we might be down to 106-109dB.

Remember though, all this is based off of the 2010-CEA directive data. which uses input tones that are similar to actual program material. Use a different input signal and the max output will change (and if someone is inexperienced with test tones and subwoofers...you can easily damage things).

Did you measure the spl from 15 feet away from you? The only way to be sure is to move your mic 15 feet away and take another sweep to see how far it drops. Of course the response will change as well.

I am not trying to give you a hard time but letting you know what I went through trying to figure things out for myself. I have owned 5 different SVS subs in the past.

Yes walking around the room using a spl meter, the output is within 2-3db except where a null resides in the middle of the room. Out of curiosity, what does your prior SVS subs have to do with this?

Just using a reference point of what I expect for spl numbers. To give you an idea of my room I could move the mic from my LP to the front the same seats which is about 3 feet and lose 3 dBs! The good and bad of heavily treated rooms. They sound awesome but suck up gobs of spl! When I owned my SVS PB12/plus/2 I would get 120 dBs max at the nearfield and 110 dBs at the LP. This was before the heavy treatments. Also that was in max output mode or tuning of 25hz. It seems you hit compression when you raised the volume another 5 dBs and only went up 2 dBs. Running compression sweeps would really show that effect best.

I know sine waves are brutal for speakers and subs so I wonder what other sweeps we can use within REW. Oh, your measuring gear is fine.

Yea I lose about 10-15db in the middle of the room, but if I move 15ft from my LP which is right in front of the TV, I get almost the same output as taking the measurement from the LP. I am sure bass traps and room treatments would reduce that.

Although my seats are closer to the back than front it is not that far off from the middle. My room is 21 feet long so the middle is 10.5 feet. I sit about 16 feet away from the front wall, maybe a little more, I need to measure.

I'm not debating whether or not 120dbs nearfield is 120dbs farfield. I agree, it is.

 

My point is that a sub that produces 120dbs nearfield (ex. 1ft) will have significantly more tactile feeling than one, say 15ft away producing the same SPL at the LP. This has been my experience, anyway.

 

The science behind that is a wonder to me...

Yes I notice the same thing!! From 15ft away I don't feel the bass nearly as much as 6ft away.

Just think of the scene in the Incredible Hulk when they used those sonic crusher horn thingys in the park. That is bass you can feel but I'm sure a block or two away, they had far less impact.

Does it?

 

Example: Imagine a recliner outside in an open field that is 1 ft away from JTR Captivator. Play some content at 120db at the LP. Now move the recliner 15ft away and play the same content at 120db at the LP.

 

Do you think the tactile feeling would be the same in both examples? I would bet 120db from 1ft away would have far more tactile feeling than the same output from 15ft away.

120dB is 120dB, it will sound and feel the same no matter how far away the source is. But if you listen to a source that's 120dB at one foot and then move to 15 feet away without changing the volume it won't be 120dB, it will be about 97dB. That's outdoors. In a room the levels don't drop at the same rate with increasing distance. How much it drops is as MK said, it depends on the room.

Thanks Bill, I was trying to say the same thing. I had a SVS sub that played 120 dBs nearfield and when I put it Far away at the front stage it could muster 110 dBs within its band pass. I lost lots of feel only due to the loss of spl. With responses being the same with no compression and the same THD spl is spl. I had my CHT subs in the back of my room and were actually 6 dBs more powerful than when in the front of the room but in the back they dropped off at 20hz and in the front they were flat to 12 hz. If you feel a difference it is because something has changed.

Interesting. Mine and others practical experience don't seem to follow suit. Granted, not all variables were completely controlled. Having said that, why do folks recommend nearfield placement for more tactile feel? Even a low volumes in my experience, nearfield is much more tactile than farfield even when calibrated the same.

 

I've personally done many tests changing the FR to match nearfield and farfield, and 100% of the time, nearfield is more tactile even at the same relative output. Has your experience been different between nearfield and farfield placement?

The only time it was different was with different SPL's or frequency. I had 8 eD 190v2s at one time and I placed 2 subs per corner at one time. I was flat and had great tactile feel. The subs in the back corners were only 3 feet away so nearfield. When I placed them all in front and still had a flat graph the feel was the same even though they were 14 feet away now. You see feel is just a frequency wave at a certain spl and it does not matter how far away it is as long as it hits you at the same spl and frequency it should be the same. I bet something was different.

Sounds like Dr. Frankenstereo......."The room is alive!"

If you haven't already, have you considered installing LED lighting as that will free up two, maybe three hundred watts on one circuit? We just recently finished transitioning to LED and CFL lighting and one would be "VERY" surprised how much they save. Home Deport has 40w and 60w equivalents in daylight and tungsten and using the electricity savings, the costs are such that it takes seven or eight months to recover the investment and you might not find need to get a 20A breaker installed. Each light uses, depending on wattage, uses between five and nine watts. Very watt frugal. Flood lights are still about double the cost of the Cree lighting that Home Depot has an exclusive on. And FWIW, I'm a huge fan of separate 20A breakers but going LED may save you from this much needed expense..

Just sharing an idea, we got rid of all our power strips by having all the main equipment wall outlets changed over from duplex outlets to four-plex outlets so our equipment wall now has twelve outlets and no plug strips to restrict the flow of electrons. Very nice.

I use the lower watt version in the rest of my house. You don't have to really change out every single bulb. Only the most used ones like the porch light or the highest power ones like floods.

Yep they sure do. Oh I just found out there is a 22 Watt version now! I have tried many a LED bulb for my house and this line has come out with a combined rating of nicest color (your wife will appreciate the warm color far more than the harsh color of typical LED's), lumens and dispersion (Most LEDs have very narrow dispersion, even the floods look like spots).

Nice! I will pick some up...thanks!!

Working with your above, we changed out anything being used on a regular basis, which in our case, was pretty much every light bulb. A lot of money but money well spent. Only a few light fixtures have been left tungsten as changing them out will produce little to no savings. Not sufficient to merit the cost of replacement. As they burn out and we've recovered the cost of changing over to LED, we'll find it to be fiscally viable. In changing things, we had the lowest electric bill in the last four years that we have records to compare against. Now if they'd invent an LED A/C compressor, we'd be golden.

You should then look at absorption chillers. Last I I looked, which was about 5 years atom they had small 3-5 ton units for commercial use in development. They run on a heat source like say natural gas, geothermal or maybe your voice coils if you heat them up enough biggrin.gif

Erm, that voice coil part was me joking!

Thanks for the above thought.
