Tekton Double Impacts

Anybody out there heard these??

I have dedicated audio room 14.5x20.5x9 ft.  Currently have Marantz Reference CD/Intergrated paired to Magnepan 1.7's with REL T-7 subs.  For the vast majority of music I love this system.  The only nit pick is that it is lacking/limited in covering say below 35 hz or so.  For the first time actually buzzed the panel with an organ sacd. Bummer.  Thought of upgrading subs to rythmicks but then I will need to high pass the 1.7's.  Really don't want to deal with that approach.

Enter the Double Impacts.  Many interesting things here.  Would certainly have a different set of strengths here.  Dynamics, claimed bottom octave coverage in one package, suspect a good match to current electronics.

I've read all the threads here so we do not need to rehash that.  Just wondering if others out there have FIRST HAND experience with these or other Tekton speakers

Thanks.

Music at 95db from acoustical instruments is not dangerous at all. Noise, however, can be troublesome as loud as 90 db.... Regularly play on a piano at 95 db and it is not at all stressful.
Absolutely! As I can attest having sat within 20 or 30 feet of the performer at more than a few classical concerts for solo piano.

Which serves to illustrate why I and the poster I quoted both emphasized that the db levels cited in his post are based on a "continuous time weighted average." During many and often most of the milliseconds or even seconds between 95 db notes that may be produced with a piano the instantaneous SPL will be far lower than that. And consequently the "continuous time weighted average" will also be far lower.

Nitrobob, the Ulfs will do what you want and then some. But Eric developed 1812s specifically to reproduce clean concert level output if you want to go for the ultimate. Hope you have some room in your room!

Is the frequency a factor in the spl?  I'm sure I spent some time in cars that easily hit 135db and higher, but under 80hz, fairly continuous "steady hummin'" in a portion of misspent youth.  Loud enough to blur vision, rattle eyeballs, literally peel paint, and sometimes actually make it a little difficult to breathe.

I would think so, Stfoth, to some degree. That would seem likely based on the fact that (as you can see in the figure at the upper right of the Wikipedia page on "Equal Loudness Contour") our hearing mechanisms are most sensitive in the area of 3 to 4 kHz or so, while being considerably less sensitive at deep bass frequencies.

So it wouldn’t surprise me if an organization such as OSHA has developed standards for maximum SPL exposure which take frequency into account, but if so I have no specific knowledge of them.

@stfoth - Remember DB drag racing? Weren’t some of the SPL kings hitting in the 150’s? In a former life I was an installer, and remember half ohm stable competition amps that put out thousands of watts into that load. They were "rated" at 25 watts x 2 into 4 ohms- so they would qualify in a lower power class. Oh, and FWIW I was an installer for the SQ (sound quality) portion, not the SPL. They were two distinct categories. Ahh the 90’s!
