Horn crackling gk neo 810

Sorry for the long post but I wanted to be as thorough as possible.

here's my problem. I set up my rig tonight just to mess around and noticed that my horn is producing a crackling sound. Almost like popping bubble rap only not as snappy and loud. The horn was at about 12 o'clock on the attenuator. So just out of curiosity I plugged in a different bass and there is no cracking or popping. the crackle is not present while I am playing only after I stop and let it sit for 5 seconds or so.

Signal chain is: relay g30 wireless, Korg pitch black tuner. Sansamp BDDI, bbe sonic maximizer, compressor, gk 800 rb. The first bass I used was an ibanez sra555 which has passive emg 40 hz pickups with an active EQ and I experienced the crackle while using it. It's faint but it is there. This bass definitely has a more prevalent mid section and growl to it. Than my other bass.

The second bass was a btb 405qm with active Bartolini mk2 pickups and active EQ. This bass followed the same signal chain and there was no crackling with the horn set at the same position.

At first I thought it could be the sansamp since it can drive an amp pretty hard which would also be hard on the cabinet. So I disabled the BDDI and tried both basses again with the same results. I also tried different speaker cables, same results. Everything had been fine with this cabinet (it is only two months old) I've never pushed it past it's capabilities I'm only using a 300 watt head ( yes I know any amount of wattage can blow any type of cabinet or a component in it). I like the horn so I don't want to bypass it and I know turning it off is bad for the cross over.

As I have thought about it when I played my last gig while sound checking I noticed some of the high volume clanking you can get with a BDDI especially if you play aggressively. I turned the presence all the off on the pedal which took care of the harsh attack. I find it hard to believe those few minutes could have harmed the horn? The attenuator was set at noon as always.

I just wanted to see if you guys had any other ideas of things I could try before I contact gk about warranty options. I really can't afford to be without a cabinet For any amount of time I play out almost every weekend. Any thoughts or input would be must appreciated!
Thanks in advance!

Ah.....only one of the basses does it, the other doesn't and your blaming the cab? Sounds like the active preamp has a problem that couldn't be reproduced without a high frequency driver (horn in the cab)? Don't blame the cabs horn if it reproduces what your bass sends it. :)

I would much rather that be the case. Some of the knobs on the bass produce hiss when adjusted. Guess that could be eluding to a problem with the horn then?

Are you being serious? :confused:
That bass sends hiss, crackles to your amp head, the horn is sensitive at higher frequencies to make them audible to your ears. The horns is doing what it is supposed to do. The larger cone speakers can not produce those higher sounds well at all, so you couldn't hear them before. Do you blame your gas gauge for dropping when you keep the accelerator to the floor?
Have that bass looked at and repaired, it is the problem. ;)

Your right it is. I plugged it into a different head and cabinet and it did the same thing. It's going to the shop on Tuesday. The only reason I was worried Is because when horns go bad they crackle now that I know it's the bass I'm kinda relieve it's an easier fix.

The horn doesn't make hiss, it produces hiss. The sound is coming from your chain somewhere, you have to find it and eliminate it. Start with all of your cords and cables.

The horn is going to hiss I don't care about that I was looking for the source of the crackle/ popping and it's my bass that's causing the problem.
