Impossible to say .The speakers are set 8 ft forward but adjacent to a large alcove at least 20ft wall to wall. Then a pinch to 12 ft wide.This where I sit then another alcove and an open pasage to a small room, The legth is the entire length of the house approximately 40 feet total but it is only seven fee tall if that high. I have a hung cieling its which just so happens to absorb sound. You guessed it it is he basement yes this a was WAF driven decision it wastooloud and those black speakers have to go I want maple. Room treatments are generally not needed because there is so much stuff to difuse the sound. 3 fabric couches, a fabric chair, an ton of baby and kid clothe,snd a depressing scattering of various pieces of audio gear that is in disrepiar.
"Rockin in the real world" with a SP6B and CYBER 800 MONO blocks BY Opera Consonance.Can't clip them.
Warning threadjack!
My wife claims that she like to listen at levels below the anbient noise. I close that door and when I am in the mood I crank it using 104 db/W//4ft La Scalas Or old jbls with the 090 drriver set. (In Paralle) with my old pal TRELJA But 110 DB does kind of hurt.Unbelievable but true I have listened to music loudly for the last 43years and the audiologists are tell me that my hearing is exquisitely sensatiuve.
