SPL Meter & SPL Calculator website -Techie Query


Hey guys, I'm trying to see how loud I can play without clipping based on my 85 watt amp and 90db eff. large floorstander speakers so I went to the SPL Calculator website

http://www.myhometheater.homestead.com/splcalculator.html

and based on the criteria I entered, it tells me that I get an SPL of 101 db at listening position. I got an SPL meter reader and put on the loudest music I could stand and I got maximum of 95db, avereage was about 90.

My question is, based on the results of the calculator am I to assume that I would be okay when it comes to clipping at my listening level threshold and that my speakers/amp were not clipping today at the 90-95 (max reading) of SPL db?

Also, does this mean that I could go as far as a max reading of about 100 before I damage the speakers from clipping?

I do realize the numbers are rough since they don't take all variables into account on the website, but roughly and technically speaking?

Thanks

When I say can I go to 100, I mean MAX reading of 100 with average about say 88-90 db on the SPL meter.
Thanks Shadone for the input. Very usefull stuff. I should mention I dont think its uncomfortably loud, it's just loud too loud for what I normally listend too. As I could tell, everything was coming in clearly, just a little luder than I would have normally listened to.

When I said uncomfortably loud, I was merely trying to excersize a point that it was louder than I expected, wrong choice of words on that one.

Now, roughly speaking how loud can someone listend to an 85 watt amp driving 90db speakers from a listening point of about 12 feet? The amp is (I think) a High Current 85 watts using dual power supplies rated collectively at 320VA

Is that considered "high current"? Also, the specs on the amp say it can go to 130 watts into 4 ohms.

Thanks again
