My new RBH 8300/PX arrived!!

Not really. Low frequencies affect hearing differently. But that is really loud.

Low frequencies are just as damaging to hearing as highs and can effect the entire range of hearing when they do. We perceive low frequencies differently (typically less loudly), their effect isn't different. I'd say that makes them more dangerous really as you're less likely to notice "oh, that's too loud" with them than with mids or highs.

At any rate, I was just surprised to read the comment about sustained 105db listening and 120db peaks. I like to feel my music as much as anyone, but I personally don't think I could stand that and would have to leave the room pretty quickly.

I'll let him answer but based on his room size, open areas, and listening habits it might not be as adequate as the larger amp. I'm guessing from the MLP it does fine, just not for filling the rest of the space. Peace of mind goes a long way

yeah it’s no surprise avrs can’t beat high wattage amps , I’ve not seen any over 160 wpch. Mines only 135 or so and older. I see people like op bi-amping the expensive models is this one active? I noticed the fancy cables built for it .
I don’t think I noticed any difference on cheap speakers.?? I could try it again.

what about those people with tons of massive subs ?
Guess so I still have ear pain from movie theaters in 2016-19. Spl got too high I didn’t think of earplugs until it was too late.

As with any sound, it's about SPL and duration. Your hearing can tolerate momentary peaks at higher levels without damage. I would think traditional sub high peak levels are operating under the idea that it's ok because it's not sustained for more than a few seconds. That does make sense. Sustained levels in a lot of music is higher up the frequency band, but not all. It depends on the content. One loud explosion is probably fine. Play some bass heavy music that's pretty consistent at 110db for an hour or something and it's a different story.

The study results I looked at before posting earlier cited 63Hz at 90db for several hours caused significant hearing damage across a wide range of the hearing range. Assuming that information was accurate, loud bass is dangerous for your hearing too (possibly worse), just like prolonged exposure at other frequencies. But really, that just seems like common sense that any thing at extreme levels for too long is going to be bad for your ears.
