K200 A5 Max load? [message #18109]

Hello all!
Havent posted here in a long while. After all the great advice I got, my K200 A5 has been running strong, and sounding beautiful for about 5 years.

I have had a single 2x15 Kustom cabinet, loaded with JBL E140 8 ohm speakers...so the K200 is seeing a 4 ohm load. Yes, I play bass.

I have another pair of NOS JBL E140 8 ohm speakers still in the factory boxes, never opened. I've seen another black 2x15 Kustom cabinet I can pick up, which matches the black 2x15 cabinet I already have. It would be great to mount the other 2 JBL drivers I have in that cabinet. That would however put a 2 ohm load on the K200a5 head.

My question...is 2 ohms simply too much of a load for the K200a5 head?

I was considering upping the power supply filters to 10,000, and the bridge rectifier to a 25 amp. But the 2n3055 outputs may complain into 2 ohms. Shurely someone here knows what the maximum safe load is for a K200a5.

Thanks,
Dave O.

2 ohms is far to much load. 4 ohms is the max load.

If you are wanting to run both cabs, you either need a power module to put in one cab or a K400 head. The K400 is 2 K200's in one box and you can run one cab from one side and the other from the other side and run a Y cable in so you go into each side, but you are talking crazy power that you will never need.

A single K200 with one cab is all you should ever need at any local gig. If you had the 16 ohm speakers in them you could run them both and run it at 4 ohms and it is brutal with 4 15's in a small area.

However if you run the K200 at 4 ohms with the single cabinet and run the line out to your other cabinet with a power module in it, that is brutal as well. It is even worse with 3 x 15" cabs......and a K400. WHEW!

If you were to find a K400 amp. It came in 4 models, the K400-1 through the K400-4 have a stereo/mono switch on the front panel, so you wouldn't need a Y cable if it ran in mono. The K400-5 was the 4 channel PA head with reverb and that model was a mono only version of the series.
Look for any of the hard tolex Kustom power amps. They made them in rack mount versions as well. The Kustom V stereo power amp is 130 watts each side and runs 4 ohms per side. They also made a mono version. They are usually pretty cheap since they don't have the T&R and have all the quality as the older amps.

Thanks for the guidance guys!

I may just find another K200 head to match.

I played for many years (made a decent living) playing bass with a K400 with two of the 3x15 cabinets. It was nice to have so much head-room, I could blow everyone off the stage, and never have any amp distortion. I'm pretty sure those 15's were the 16 ohm versions, so the amp was only seeing 5.3 ohm loads on each side.

The K400 head I had was one with the stereo/mono switches.

After I stopped gigging, I put some horns on top of those Kustom speaker cabinets, and used the K400 for doing mobile sound system (DJ) work. I found that I could go into the K400 line-level from the mixing board, and switch the amp into stereo. I had the loudest, cleanest mobile DJ set-up in the area...by a large margin.

I wish I still had that rig, but it sure was a pain to move around.

Thanks again,
Dave O.
