Speaker Volume

I have tried a few phone apps to use, but heavily rely on my Radio Shack meter. A few good meters are available, starting at $20, going up to double, that I feel are superior to using the phone apps. My feeling is that the phones ( the built in mics, and the casing part, where the mic is on the phone ) are the weakness, as opposed to the apps. As yogiboy has said, 105 db is loud. I play my system, at times, when peaks hit 105 - 110 db, but these peaks are not constant, and the normal range is 20 db below that, at 85 to 90 db, which is still too loud for some people. I take my own hearing tests ( there are apps for that ), which are through headphones, and I visit my audiologist every birthday. There are many decibel graphs available, showing a wide range of user products, such as blenders, sink disposals, and much more. Enjoy ! MrD.

Yes, 105 dB IS loud. IMO, @mrdecibel  has a solution. According to the specs he has researched, your speakers are not presenting the bass frequencies which would be responsible for "loudness." 

Add a subwoofer. There are dealers who have trial periods or return policies such as Music Direct.

Get a roll of duct tape and a friend. Hold one speaker up to each ear while the friend wraps them tight around your head. Use the whole roll. Any gaps bass will escape costing a few dB off the low end. Leave just enough space to breathe and suck a couple beers or dram of Scotch through a straw. Not quite concert ear damage but close.

Get a double adapter for your headphone jack.  Use a set of ear buds in one output and then a set of cans in the other and use both at the same time.  You should be good to go then......

Guess I will have to settle for 105.  I don't listen at those levels often. It's not like being at a live concert.  I think if it made 110 to 115 that would be ideal.  I feel my ears strain at 107-108.  I am sure you have been to live concerts where things rattle for a while afterwards.  Once or twice a year is fine. I just want that occasionally.  Since you have told me this is normal, I can go with it.  BTW, my hearing is good. 

I appreciate all your input.  Thanks!
