Hi Antti,

I came across with a speaker from Tobian Soundsystems. Model 15HF uses mid-high Compression Driver 4.0" without mid-high crossover.

Read again....

4" diaphragm (same size as your Orphean) and if it has no tweeter then why is an crossover needed? Easy claim... :grin:

It will still have a crossover for the bass to midrange to prevent it from damaging.

Oh, your Orphean plays well down to 220Hz and my extended Oris 150 even down to 160Hz!

Not sure where they claim their crossover frequency and possible EQ network needed to get things in balance?

Their horn for the mid-high frequencies is only 12"... impossible for efficient loading down to 300Hz, at least to be able to cross that low at 99dB efficiency.

You can't fool physics! You can fool people with too much money without too much knowledge and that is a pity... buying stuff for way too much money and getting inferior quality.

I am sure those speakers sound okay (high efficient bass driver and hopefully good quality compression driver without too much compression - read 3rd harmonic distortion).

I am sure your system sounds a lot better!

Cheers and Happy New Year!
