RE: Alternative to the EV ST350 horn tweeter on EV Sentry IV-A's

Paul this is great! Thanks. The good news is the XO is still on the test bed board so I can try this! The bad news is that I thought I had the XO done and was finished tossing $$$ at it!

Would you provide your thoughts on the possible best way to proceed?

1) Keep my current XO point at 4700hz and do the prescribed EQ after the XO. Reading the new EDS, it sounds like the circuit works for any XO point "at or above" 3000hz?

2) Keep the upper band pass at 4700hz, lower the ST350 high pass to 3600hz and use the prescribed EQ circuit. Would this give me a bump in FR at around 4150hz?

3) Change both mid and high to 3600 and use the prescribed EQ circuit.


I in my listening tests I liked the 4700hz configuration better than the stock at 3500. The transition was more seamless and the high frequency smoother. Additionally the higher point potentially offers a bit more tweeter protection as I removed the STR circuit. You are quite right about the tweeter blowing paranoia. Removing the treble attenuation and STR were big improvements.

Thank you for taking the time to "bonehead" this for me!

Cheers,
Geary
