80 cents will still be no issue! So I just call you on the gr research number to order it?

Yes you can.

Just an FYI for anyone tinkering with speakers or considering sending one to Danny for possible improvement.  Working on a $3K retail set of speakers from a well respected manufacturer.  Push on terminals used on crossover board and all driver connections.  Did impedance sweep on as manufactured condition.  Impedance sweep after ONLY changing to solder connections at the drivers (woofer, mid, tweeter).  R(e) 0.3 ohms less with soldered connections.  Don't know yet if there will be an audible difference.  Getting rid of potential connection problems is worthwhile peace of mind.

It was audible on my Super 7’s.  Subtle but more than I expected.

Hi, I fairly recently blew a pair of tweeters on my much loved AV123 Rocket 750's. I found the tweeters but after replacing them one of the speakers still won't play anything through the tweeter, leading me to believe the crossover may be blown. I believe the crossover was designed by you (Danny Richie) - I'm interested in fixing it or replacing it. Would this be possible?

I can provide you with anything you need.

Chances of the crossover being blown is almost zero. It is usually a connection issue.

I will double check the connections.

New Audiocircle member. Hello All.

I'm hoping Danny can make my speakers better. He has one of my Martin Logan 35XTi speakers in his possession now.
Hoping to hear something from him soon.

Hi Danny--
Have you tested a Dynaco A25?  The stock crossover is very simple, a 5 uF capacitor in series with a resistor, or resistors, selected with a switch.  It's a simple matter to replace the wire, cap, add a bypass cap, ditch the switch and use 1 higher quality resistor, add tube connectors, but can any more be done?
Thanks----------Mark

Back then they typically didn't use a high pass only filter like that because it was ideal. It was used because it was cheap. I am sure they could really use a real crossover.
