Is the 18sound ND4015BE actually available for sale right now? Their website has it listed as "preview"..... Vendors in the USA? I guess I could try to contact the USA distributor to see... I did some searching though and it doesn't show up so far for me.... trying to get an idea of price for a pair.

I've yet to find the Radian 951 anywhere online to even see it let alone find a vendor that sells it... Behringer Electric as in BEHRINGER: Home ????

Sorry to be difficult and uninformed.

jzagaja -

How would you evaluate, or place a verdict(pro's/con's) on these (material-resonance characteristics?) measurements between OS-12 and SEOS-12 with DE500?

Autotech listened FP10 vs. fiberglass SEOS-10, hard to tell difference. Maybe there's an audible difference when one use waveguide/horn below 1kHz. Poured when knocked is like stone means stiffer and this is what you see on spectrogram.
