I have no idea if this was just deep bass or something to do with shockwaves though?

you see, the difference between me and you is that in such a case I hear the roar of a jet engine flying up above me and I don't dilusion myself that I'm feeling something.

I wasn't being delusional. There really was lots of bass.

The Vulcan bomber also set off several car alarms too and I'm pretty sure that they weren't being delusional. Wink

yeah, that's a nice one. but sometimes you can go past a car and the alarm would start off if the alarm is too sensitively set up.

nevertheless a strong gust of wind would start an alarm too but then we're talking about spls comparable to that of a jet plane flying by, i.e. a hurricane.

my point is at normal spls from noral sound sources sound waves don't have enough energy to excite the body. but speaker cones can. so that means there's something wrong here.

I think the link below may prove that it is perfectly possible to feel sound through your body .

You can feel the bass from a kick drum when you listen to a band playing live in a small venue.

Yep, go to any rock or pop gig in a small indoor venue, or stand near the front in a large venue and you'll get bass that you can feel when the drummer or drum machine or bass guitarist is playing.

I can't believe this is even being questioned.. When we were young my friend had 2 x 12'' subs in hs mk3 golf and when playin smack my b*tch up or bass test CD it was so powerfull the roof and rear 3/4 used too vibrate over a cmand would hurt your fingers to rest on the panel. Also it would be physically hard to breath as it was vibrating your diaphram so much. Aside from that pretty much every small venue gig (punk rock/hardcore etc) i've been to whre they mic up the kick drum and bass amp you can feel every pluck or kick.. Thats the reason I love it as it makes you 'feel' the music.. Plus have you never heard of 'brown noise'  ROFL

 

As for TL etc does anyone know if my Pro-acs are TL or BR? I know a lot of Pro acs are but can't seem to find info on mine.. It says on the stats and in reviews they go lower than pretty much any other standmount at 30hz.. (i'm not saying they do i'm sure theres plenty tat go lower) Once I sort out my interconnects to smooth out/bring out more bass it should sound fantastic Biggrin Can't wait!

Thank you.

It's a pity that none of the speaker makers on here have seen this and given informed comment.

Yeah be good to hear Kefs story as they are probably the most advanced technilogically and obviously swear by bass Reflex.. The devopment of the LS50 video impressed me.. To be honest I get the feeling that once you go over a certain size/amount of drivers (like yours) it prob doesn't make much difference.. I think TL is more to get the most/accuracy out of moniter/2 ways.. Also be interesting to hear ATC's sealed opinion vs PMC TL for accuracy as they both claim to bet 'the best/most accurate monitor company'

Borderline off topic, I know, but anyway... Anyone ever heard these? It's Ear's Primary Drive loudspeakers (http://www.ear-yoshino.com/products.php?catId=6). Looks a little like the Jamo R909, with its open baffle design.

natural source of sound. this is my point all the way that amplified sound through speakers does what natural sources don't.

another one that can't read or don't understand what's written. natural sound sources. this is my point that speakers do excite the body.

I was actually considering those speakers for a while... who knows, maybe if I had a chance to audition? they say Tim does not BS you. if he brands something with his name it has to be a least good.

Oh, I understand now. Yes I did totally miss your point.

 

But seeing as 90% of the music I listen to at home is rock and pop, and seeing as I get most enjoyment when the reproduction sounds like a live event - except quieter - I couldn't give two stuffs whether any natural sources of sound produce the sort of pressure waves that you get from PA systems and good hi-fi systems.

RE: Transmission Line vs Reflex Ported vs Isobaric

Sound from a speaker is just a pressure wave the same as a naturally produced sound is, surely?

RE: Transmission Line vs Reflex Ported vs Isobaric

I don't know if anyone read the link in my last post Smile

But here is the most relevant section .

 

 

Glennie may be one of the best listeners in the world, because she has had to develop the listening abilities of her entire body. Since the age of 12, she has been profoundly deaf, which means her ears deliver only a fraction of the sound vibrations that she picks up most vividly through her feet, hands, chest and whatever else in her frame responds to the vibrations from her various instruments.

"The body's like a huge ear," she says. "It's as simple as that."
