Rainbow SLC's How to bypass the tweeter protection circuit.

[Trepkos 10+ year member]

The '08 Rainbow SLC's have a protection feature in the crossovers that when the tweeters reach a very loud volume level or receive a large amount of power they temporarily cut out until the volume is lowered for a few secs, then they reactivate.

Does anyone own a pair of components and have bypassed this feature? I seemed to think it may be a little over protective but then again, I dont want to blow my tweeters either.

Leave the protection circuit intact. You don't want to blow the tweet and void your warranty for an extra db.

I actually replaced the halogen bulbs with silver wire jumpers on the cross overs but they still attenuate at high power levels.

Go active, that's the best way...ditch the passive crossovers, and run it active.

I have never had this problem.

You own an '08 pair of Rainbow SLC's?

yes, and I don't need them any louder than they get -- never had a problem. I just mention it because it makes my wonder why your set would be giving you problems.

Gains are at maybe a little between 1/3 and 1/4, set to full, I don't ever really bring my volume above 26/35, sometimes not above 23/35 on the headunit. The volume offset on the head unit is set to +3db, the EQ fourth band is set to FQ 14k, +5 gain(maybe be an issue here), no loudness on the HU or the Ipod.

They get really loud and retain the clarity. But for extremely loud songs, they will play for a few seconds at full volume and then shut off the tweets temporarily, I can lower the volume and the tweets will come back into play to the normal volume level that they were at originally.

Just wanted to throw this out there, but a while back I was running a set of Rainbow Profi Vanadium phase plug two ways with the passive crossovers, and I had the same problem that you're having. Turns out after testing the crossovers that one of the crossovers was bad.

I hope that's not the case for you, but how you describe your tweets shutting all the way off, and then coming on after a couple minutes after lowering the volume was exactly how mine were, too.

How did you test them?

I had my installer hook up a little device he had in his shop to test their output. I can't remember what it's called, but it's about as big as a DMM.

I think it may just be that I have the volume gains and eq gains set a little too high but still, the protection circuit should not be working if the halogen bulb has been replaced with a silver wire jumper, or so it is told in the manual, so it may be an issue with the crossover.
