    I'm running my 604's at a crossover point of 1150.

    2.3 Inductor on the LF. 9.1 cap on the HF. 9.1 cap/15 ohm resistor for the LF zobel and a 2uf cap across the hf wires. It's the only choice I have short of having them not sound good. 515's are garbage much above 1000hz. Still deafening and still working. even being driven with my 90 watt SS amp.

    Edit: I changed the HF cap to 9.1uf

    Original 604's were crossed at 1000(and are to this day perhaps the best sounding 604 particularly through the XO region).

    I cross my g's at 1250, but I try to be very careful with the volume knob...

    Unless you're running a mild slope like 6db/oct, you're probably safer than you think.

    I'm not saying you should try to push your 300 watt amp to clipping on them, but i think your ears will tell you when you're stepping on the danger threshold.

    I never did think of the 1600 XO freq as golden.To me the magic was how it sounds. If you would like to do some listening tests PM me.

    A buddy stopped over today and confirmed that they sound better than he's ever heard. Like I said over on AK if a 515 is indeed what the woofer section is, they are rated at 20-1000hz why they mated that with a horn that shouldn't be driven below 1600 is beyond me. Juniper All I'm gonna say is mine go well into the ear splitting level without batting an eye. I can almost hear them laughing.
    Don they sound much more like they should this way.
