How loud in DB, Is "cranking it"
Gents;
i just just got a new amp and was Playing my 87 db efficient speakers( Thiel)
My speakers 8 ft apart and I sit 9ft back
I was just playing my amp at "30 watts class A" and I heard 97 db at listening seat.
I normally listen at 70-75 db
I was told the Xa30.5 might not have enough power! In my questions to Audiogon
To me it's WAY more than I need......no issues here. If my amp is considered underpowered, You guys must be nuts!!
lol
So; the question:.
How loud is " crankin it" for you guys
and
How loud do you normally listen?

80 to 85 db is cranking it for me The following is my understanding about sound and power 2 speakers increases the sensitivity by 3db so (sourced from enjoy the music dot com) 1 87 db speaker will produce 87 db of sound at 1 meter with 1 watt of power 2 87 db speakers will produce 90 db of sound at 1 meter with 1 watt of power Placing a speaker in a room increases the output by about 4db so (sourced from enjoy the music dot com) 2 87 db speakers will produce 94 db of sound at 1 meter with 1 watt of power Power required for average sound (Sources from PSB speakers) 2 87 db speakers will produce 94 db of sound at 1 meter with 1 watt of power 2 87 db speakers will produce 97 db of sound at 1 meter with 2 watt of power 2 87 db speakers will produce 100 db of sound at 1 meter with 4 watt of power 2 87 db speakers will produce 103 db of sound at 1 meter with 10 watt of power 2 87 db speakers will produce 106 db of sound at 1 meter with 20 watt of power 2 87 db speakers will produce 109 db of sound at 1 meter with 40 watt of power The inverse square law states that when the distance from the source is doubled, the sound pressure weakens by 6 dB. 2 87 db speakers will produce 96 db of sound at 3 meter with 20 watt of power 2 87 db speakers will produce 99 db of sound at 3 meter with 40 watt of power You also need to account for musical peaks which are louder than the average sound and voice coil heating which affects the speaker sensitivity |
Everyone has different tolerances, I like listening to small jazz ensembles or symphony at what I would say are "live" levels.... The problem is what is that? A live Rock concert can hit peaks of 124 db and 121 db is the normal threshold of pain... while going to a symphony, you may be lucky to hit 92 or 93 db. And no, I would never attempt to listen to anything in my home over that mid 90's db point. Ok, so what is cranking it? |
How loud is cranking it??? Maybe this will help you understand how loud I normally listen: https://www.youtube.com/watch?v=4xgx4k83zzc |
Your amplifier is capable of over 150 watts @ 8 ohms as it has an additional 120 watts (class B) of headroom. It would have even more headroom (> 150 watts) pushing your Thiels. Depending on how fast the meter is you may not even notice the amp spiking into class B to cover transients. I listen in the 70’s with peaks in the 80’s (higher dB’s trigger migraines). I’m just getting over a headache that started yesterday afternoon (spent an hour waiting @ our local Apple Store for a tech to fix my wife’s iPod). |
