How does it make sense that they only go down to 60hz when they have 4X10 inch woofers ?

As it also depends on the needed SPL, 10" drivers are in the PA world usually mid drivers, woofer are typically 18" arrays which this company also provides:

If this speaker is the same competend build as the 'competent' information on there web about it. I would be very, very sceptical about it.

They are short on measured data.

I think you could easy say very short on every data.;) Or maybe iam to stupid to find some? The only data i can find is that product information, and thats nearly nothing.

I guess this company depends on professional installers to move product. They still might want to toot their own horn a bit on the web site.

Hi

This is something that tend to fly in the face of conventional wisdom... Full range speakers may not be "the way", to go in a most systems. This has been studied by eminences such as Floyd E. Toole, Alan Devantier, Sean Olive and Earl Geddes to name a few.. There have been others... It seems to be a better design strategy, to leave the low end to subwoofers and optimize the speaker from where you would cross with subwoofers (as in several). This is, to paraphrase someone here and the Mandalorians ;) , "the way" :D.
Geddes, top of the line, the Summa , was a 2-way with an 18 inches woofer + a waveguide fitted with a compression driver... stated FR was from 60 Hz to 18,000.oo... Sensitiviy was at least 96 dB... I have no doubt that this beast could play 120 dB + at listening positions of several meters...
No idea about this RTJ speaker, but leaving the <60 Hz to subwoofers, make sense...

Peace.

I cross to the real woofer (15") at the baffle step, 110Hz, to minimize Doppler distortion in the SEAS. I didn't pay that much for drivers to screw up the signal by misapplication ;) I imagine they had the same thought; these are made to run loud and clean.
