Twetter is crossed at 2.4kHz LR 2order, any hint what capacitor value to use that will not mess into crossover slope ?
I have made the crossover mistake, I'm sad to admit
At one point in the design process, hooked up my sb29rdc to the woofer channel and fed it the woofer's signal at decent volume for about 5 secs before turning it off. The tweeter distorted like crazy but amazingly survived unscathed. This is a seriously robust tweeter!
What happened in my case was quite different. What did get fried, fed the proper lowpassed signal from the woofer channels, was a Rival r176p woofer:
Paper woofers by Rival Acoustics – Rhythm Audio Design
Which can take an awful lot of power (I had broken them in with an adcom 555) and they didn't complain at all. Indeed they played for days with these the fa123 without complaining until 'the incident', then was dead within 3 seconds. Looks like I can't even get a replacement now, and the enclosure is a transmission line designed specifically for this woofer, so the whole project may need to be scrapped.
If it's any comfort, you might consider my unit as having been 'refurbished', it had already been back to hypex for repair when it was DOA. Presumably brand new units are more reliable.
