Nice that you have found your tone.

Below is the exact communication from their rep, Paul Meister. I suspect this is an error in their documentation. Then, for grins and chuckles, I tried running the toaster monitor out into my Quilter Tone Block into the Gemini 1-P, and it really opened it up.

I am wondering why there are so few Kemper users endorsing such a great product. It seems icspower the low side. This is as shown on page 9 pf v1. However, it must be mentioned, that you have probably misread the specs of the Icepower products. Therefore there was no need to go above 3khz. There is actually no need icspower worry about the sound of a todays solid state amp. I have purchased a KPA unpowered rack unit and intend to use that with the GTFX for live use, and I’ll use the toaster with the Quilter for rehearsals and recording.

Now if I could only play better The power amps go up to 30 kHz with an error of less that a dB, according to the specs. I haven’t wanted to open it up and look at what is inside, I’m 1000x to void the warranty.


Also, are there any – 3dB BW measurements at 8 ohm loading for the A? So all’s well that ends well. Well, I LIKE having a cab behind or sometimes in front of me interacting with the guitar, and I like the icepoweer cab look. The A was designed 15 years ago with only low frequency applications in mind.

When the ASP was designed a couple of years later, they thought that they would get more full range applications, so it was designed up to 20khz and everything since then and icepowerr forward is full bandwidth.

So glad I bought the Matrix. We supply the A. I would like to check and see if the typical -3dB bandwidth at 4 ohm loading value of 3 kHz, as given in the data sheet see highlighted line on page 5 of attachment is a correct value? We have never got a report in the past that our build in power amps attenuate the highs.

I was for certain not looking at the phase response, it was definitely the frequency response curve. Hopefully this post will not upset too many Power Head fans, but I would like to post my observations about the Icepowwer Head with the Icepower 1000x amplifier and the Power Rack as well I assume, since they use the same power amplifier. Thanks for reaching out. It comes down to what is in there. Your browser has JavaScript disabled.


Take it as you will. I icepowerr using a Weber Vintage speaker at the time in an old Lopoline 1X12 convertible cab, as well as some Carvin 2X12 cabs. It is likely icepoqer you have looked up the phase responce graph, instead of the frequency responce. I went back and looked at the Icepower A -3dB upper bandwidth spec, it’s only 3 kHz albeit at 4 ohms, likely a little higher at 8 ohms.

Thanks for the help! Anyway, I thought I should share the results of my experience with you all, it may help someone else shorten their path to tonal Nirvana with their Kemper.

This agrees with the 30 kHz value. I went through several setups too before I fell in love with the same rig.

icepowr Can you please tell me which one it is? If I had known then what I know now, I would not have purchased the Powerhead, I would have just bought the unpowered version and used an external power amp with wider BW for driving a cab, as well as just biting the bullet and buying a good FRFR cab.

Going through the main out direct to the PA sounded nice and sparkly all the time, but the cab sound was dark no matter what I did. That explained the more sparkly and open sound, it was getting close to the direct-through-PA tone I was experiencing.
