Another note. People compare this sound to jets or gun shots. Its totally differerent. Shoot my AK47 or AR15 and you willl see and feel the different. The gun feels like its going to blow out your ears. Hurts like hell and ear plugs are needed. I made that mistake and me and my cousin shot both at the same time. My ears rang for hours and I could not hear anything. It didnt bother him but he is in the army so he is probably deaf from all the shooting. I'm afraid hearing damage has been done already. I suggest seeing an Audiologist. When I was in my 40s, I had a punctured eardrum because of sports. Thankfully, it healed with no hearing loss. The silver lining is that I have an excuse to see my Audiologist and I made a conscious effort to go every other year!

It happens when I run a sweep I have on a cd. I have no idea what frequency but it will go from around 115's to 126 around certain frequencys. It reminds me of my car days it is that loud. I would bet my whole system that its way over 112db. lol That is weak and I have been around bass long enough to know when its up there.

Any just for reality check, for an ED A5-350 to generate 126 dbSPL @ 14 feet, it would have to have 112db system sensitivity with its 500 watt amp. It's a fine subwoofer, but that does seem a bit high... especially since 112db sensitivity is the theoretical maximum (100% efficient loudspeaker.) So you are saying my sub would be lucky to hit 112db? I bet anyone my whole system come to my house with whatever you want to measure and it will smoke that puny 112db. If it dont take all my speakers. Anyone up for the challenge? Free speakers since some of ya think Im nuts. lol

Subwoofers live down around 85-89 db sensitivity typically. My point is that 126db SPL is unlikely from your subwoofer @ 14 feet, so it's very possible that your SPL meter is not giving you accurate results.

See if you can find out the sensitivity of your subwoofer, or better yet the rated system efficiency.

ok yall. I just spoke to Alex from Ed. He explained to me for instance if my sub is capable of 112 to 114 in an anechoic chamber. That accounts for no boundry gain. having it corner loaded will add 6 to 9db. to put me around 121. ANd he said at certain frequencys it may be possible with the way my room is set up to actually hit 126. So My bet is on for anyone that says it cant hit 112 or 114 or whatever someone said. lol

And you are right I dont think I understand what you said. My bad. All I know is what I hear and from experience thru the years.

I love music to much to damage my ears also I always use ear plugs when around power tools etc..

Once your hearing is gone it will never come back.
