Celestion G12H-90 vs. G12K-100?
by mr_slugworth on 2012-06-29 08:47:25

So I have a new DT25 combo on the way which I'm pretty stoked about.  Had a DT50 for and while I thought it sounded excellent, but it was just too big and loud for my needs.  I know the stock speaker in these amps is a Celestion G12H90, which is custom-made for Line 6.  I have another combo which I'll sell off to make room for the DT25, and that combo has a Celestion G12K100 in it, which I really love.

I have read that the H90 is most similar to the K100.  Obviously I can do some A/B comparisons after the new amp gets here, but I was wondering if anyone out there has compared the two speakers and can give any insight on similarities and differences between the two.

Thanks!

Might be worth sending a PM to SpaceAtl.  He's a wizard when it comes to speakers (and lots of other things too).

Cheers,

Hey there...I have a couple of those GH-90s...I like them. A much better choice for a stock speaker than the Seventy80 I think...I am not much of a Celestion fan and I have never compared the G12K100...My guess is that it is probably similar...The GK could have a higher SPL rating...hard to know...Definitly something I would compare and perhaps swap out before the sale...

I have loads of experience with the G12K100. I've got 2 Groove Tubes amps which use these speakers as OEM stock. They are the unsung heroes of the Celestion line; not used in many guitar amps because they were designed to be keyboard speakers(the "K" designation) but they work great for guitar. They are very smooth, flat response speakers with high power handling capability. I remember reading that they are very similar sounding to the H90 os similar too, but have never A/B'ed them. Why not tryit out and see if you like it?

I have a Avatar cab with a v30 and G12k100 that I use with my DT50. I've gotten loads of compliments on my tone

Thanks for the input guys!  I've been on vacation but should be able to get my hands on things tomorrow to crank it up and do some speaker swapping.  I'll report back after I've formed an opinion.

No speaker swap for the DT25 combo.  You can't get the stock speaker out without taking the whole amp apart!  I got the back panels off and power tubes out (and noticed the external bias points... nice touch), but that still wasn't enough.  The compact size of the DT25 combo means that everything is crammed in there pretty well.  I stopped short of taking out the transformer and decided to leave well enough alone.

Usually, the amp designs have been where you can pop out the entire amp chassis out by removing 4 screws in the top (sometimes the handle too)...usually comes out the back of the amp...But maybe this is different...I thought I remember reading a post by a DT25 combo owner that you had to take the chassis out to be able to get at the bias points to adjust...

You do have to take the chassis out to remove the speaker. But it's not hard. Just the a few screws and it slides out.
