What about the Supravox horn (Off Topic)

I do not think that you can cross that horn as low as 500Hz. Its way too
small for that and looking at the frequency curve shows the roll-off
starting at 1kHz already.... The GMF driver is capable to reach ikHz
though but optimal integration migth be tricky or even impossible due to
the differences in character and speed.

Hey Bert,

It is not an idea of myself, it just the kit that Supravox sells. They use a filter which uses 6dB/oct for the tweeter and 12dB/oct for the woofer, so they make use of the roll off of the horn. They also say that it can only be used in hi-fi application, if you want to use powerful amps you should cross at 1500H. With a sensitivity of 98dB/w only 1-3 watts are more than enough blow yourself out of your seat. Again, this is how supravox designed it, it is not my idea. Ofcourse tyeh say it is wonderful. The reason I ask is because I have 2 285gmf drivers.

Cheers,

Jacob
