What's the word on the 2X12 CTS T&R Kustom cabs for guitar with a K150-2 Head? Are they 8 ohms? Will my Frank bass head sound good through it? I use the Frank with a Peavey 8 ohm cab sometimes and it sounds good and pretty loud. I run it mainly through 4 ohms though. I'm kinda spoiled with the Frank guitar sound and measure other Kustoms against it and the Frank always wins.

The 2-12" cts cab should be wired for the needed 8 ohm load that the K150 wants to see if the speakers are orignal and still wired in parallel.
A resistance check wth a ohm meter will show a reading above 5 ohms, but below 8 ohms right at the jack.
The Frank head will work fine with the 8 ohm cts cabinet, but its 90 watts of rms power at 4 ohms will be only some 60 watts into the 8 ohm load.
If you have never tryed it, jumping/bridging with a short cable the two channels on the metel face K150 and 250s can give alot more tonal variations to your sound.
You might end up liking it better than the Frank head.

Wow! I never thought about doing that but I've only had the K150-2 for a week. So the channels aren't out of phase like the Frank or 200 series? I remember reading something about that on the forum

Kustom made two basic versions of the 2x12 cabinet. The first version used 16 ohm speakers wired in parallel for a 8 ohm total load. These cabs were offered with Altec, Jensen or CTS. These cabs have a slight taper from top to bottom when viewed from the side, and have black grill cloth, either aluminum or chrome port tubes. These cabs were designed for the K100-1 and K100-2 heads.
The second version, no taper on the sides, black grill with silver threads and used the KEI brand speakers and are 12 ohm speakers wired in parallel for a 6 ohm load.
Of course after 40 years, no telling what brand or impedence speakers are any kustom cab without taking the back off and looking at what brand speaker is in the cab.

I have the K150-2, actually I have three heads and 2 cabinets. One has two 8 ohm early 60's CTS alnico type and the other has a single 8 ohm Altec 421A. I get fantastic volume and tone from the CTS's running the K150-2 at 4 ohms. The single 15 Altec does great but it doesn't have near the bottom or fullness the two twelve has, but then again it has less paper moving air at more resistance and that can be the big difference between them. Getting the Frank sound out of a metal face Kustom would only be posible with a good digital EQ to condition the signal before input. That conditioned signal fed into the Frank would again take you to a whole other guitar heaven. The Franks in my opinion have the warmest of all Kustom heads made. I have like six of them and they all have that same warm, rich, robust sound I look for in an amp. Steve C
