I purchased a cat12c about a year ago new from seaton sound and a month ago it started making intermittent ticking and popping sounds. Below is a thread from the forum with what sounds like similar issues. It is still present with the XLR cable unplugged completely from the speaker. It seems to be occurring more frequently as time goes along. I think this may be a known amp issue but does anybody know if this can do any harm to the drivers?

I'm also open if anyone knows of a quick fix I can do myself.

I have sent an email to Mark as well and am awaiting a reply

Thanks for any help or suggestions in advance

Update: it looks like the red protect light "PROT" illuminates during the popping sound

Same exact story for me with intermittent popping and audio cutouts on my CAT12C amps. I sent all three of my amps in for repairs the first time in May of 2016. They were returned to me 6 weeks later. One of the amps was fixed but unfortunately the other two still had the exact same problem. I lived with the popping for several more months, but decided I couldn't take it anymore. It was getting embarrassing every time a friend came over to hear a demo of my "high end" system to then be so distracted by popping and audio cutouts. I sent the two still-popping amps back in mid-January and Mark/SpeakerPower still has them to this day, so I guess we are at 4 months and counting now without being able to use my home theater (6 if you count the first time they were sent in). Mark contacted me about a month ago to say the amps would be ready in a week, but multiple weeks have passed with no amps and no responses to my further emails. 

When I had trouble with one of my Submersive's amps buzzing in the past, Mark sent a new unit right away and I just returned the defective one. I'm not sure why this policy does not apply to the CAT amps, but should definitely be instituted in the future if he has any hope of retaining customers.

I did receive my amp back in about a month from speakerpower. I actually corresponded through email with one of their Representatives to describe the problem and they apparently couldn't find a problem in their testing of the amplifier. “Input replaced, no problem found” was what was on the work order page that was sent back with the amp.


After reinstalling the amp it did make a few popping noises as before but they were much less frequent (1 pop every 24 hours or so in normal use in our living room system right after receiving the amp back from speakerpower). I was using an auto switching surge protector to allow the speaker to power off when not in use. Thinking this may have something to do with it, I unplugged it from this receptacle and now have it plugged directly into the wall outlet and the popping is reduced (1 pop every week or so with the speaker powered on 24/7). I have no idea if changing the power source made any difference in reducing the frequency of pops or if the new input that speakerpower installed made a difference but it's now infrequent enough to not be a problem.


Mark was very responsive and sent the pre paid shipping box within a matter of days

I think that Nark has been less personally involved then he was in the past.

Hi Nicholas.  You already have an e-mail I just sent with more info.  Your amplifiers are headed back today from SpeakerPower, as are the amps for 2-3 others.  There was a miscommunication between us on authorizing the repairs to get shipped out which is now fixed/clarified.  As with the warranty on most any company, we reserve the right to repair, or replace the items with refurbished or new units.  Ultimately it's a cost and inventory limitation.  We do much higher volume of SubMersives, and the Catalyst amplifiers are even more expensive than the SubMersive amplifiers.  If we don't have amps on the shelf or on order yet, it's a 3-5 week lead time before we could possibly ship a new replacement.  In some cases I will have other units on hand from testing, repairs, etc, and if I am confident there are no issues with them, we might send those as replacements.  Apart from this hard to observe/diagnose issue, repairs on the SpeakerPower amplifiers have been very reliable over the past 12 years we have been working with them.

The popping referred to has been observed in 10-20 units over the past 10 years and a few hundred units.  It has proven to be a tricky matter to diagnose as our amp supplier has only been able to reproduce/witness the issue in 2 units at their facility within the limits of working hours.  I have been testing units here, and we believe we have the most likely sources of the issue narrowed down.  I will soon have a similarly repaired unit running in my home and another which has a different repair I asked them to try.  I'll be observing it over a long period to verify.

I too have experienced the intermittent popping/ticking with one of my three Cat12c LCRs.

Upon first hearing the pops/ticks, they occurred so infrequently I felt no urgency to pursue the issue. The sporadic noise was subtle, and easily attributed to other components in the chain in addition to the amplifier.

Several weeks passed and slowly the issue was becoming a bit more frequent. I knew now I'd need to get serious about determining what was going on. However, whatever this was, it occurred so rarely that it may take some effort to fully flesh out.... or, maybe not. Approximately the same time I decided I needed to do something, I began to realize I hadn't heard any pops or ticks for a while. That was a few months ago and I'm over it. Not a single errant noise since.

As I've shared before, this system is both the family daily driver, and a full tilt A/V rig for full immersion experiences. Point being; I'm positive it's not popping and ticking anymore because the entire space/system is the focal point of our busy home (the kitchen occupies the rear 25% of the space).
