What's your opinion of this speaker?

Depends on your application. In the Mesa context, I like them in the Lonestar combos and cabinets. I don't like the three-quarter back cabinets filled with them.

The C90s put in a good cabinet are stellar for clean tones and mid-gain tones. They're full, meaty, and articulate. That being said, all of that is incredibly subjective so your mileage may vary, that's just my opinion.

I have them in a 2x12 open back Mesa cab and they sound big and clean. Not much break up in them.

I have two 90s and two 75s in a 4x12. I like the sound of it, but I haven`t been able to A-B it with a full V30 cab, for example. I use it with a Mesa Caliber 50, and it can be as middy as you want, so the slight scoop of the 75s doesn`t bother me. It`s a tight and loud cab, that`s for sure.

I have 2 C90s in the open back side of my Road King cab. They are very full sounding speakers. Pretty tight, even in the open back, with very good low end response. I'm shocked at the thump I'm getting out of them in an open back cab. They are not nearly as bright or harsh as the V30s (in the closed back side) they're paired with in the cab. Very well balanced speaker. I've also tried them out in a 2x12 oversized Mesa cab with a closed back. Again, very full sound to them. Huge low end in that oversized cab too. In both cabs, they sound great in a mix. Very full sound that sits well with the band.

I have some reservations about the speakers, though. I don't like how they sound when it's just me playing. They seem somewhat sterile and lacking character when I'm playing alone. They're actually some of my least favorite speakers in this application. The reason I keep them is I really love how they sound in a mix at volume. If I didn't play in a band, I'd probably never use them. But with the band, they sound fantastic.

MC90's are great with the right amp. I don't like them typically with vintage or vintage voiced amps. They work great with the mesa mark series. I find them to be a pretty thick sounding speaker, clean, slightly bumped midrange, rolled off highs. They have more midrange and are thicker than a CL80, but have less mids than a WGS ET-65, but more bottom and high end than the ET-65.

Currently I have to MC-90's in the top of my Mesa metal grill 412. There are 2 EV's in the bottom. The cab is actually extremely versatile and sounds good with all my various amps. I did have a mesa metal grill 212 cab with the top open, it had 2 MC90's. I really got to heard just the MC90's in this cab, it was in that cab that I really formed my opinion about them. I think they are best mixed with other speakers.

I am frantically trying to find out if the C90's use the low resonance (444 55hz) or high resonance (1777 75 hz) cone. Anyone know ?

Celestion will not disclose this info. My question goes unanswered on the Mesa Forum

I've got to pull the C90s out of my 2x12 and put them back in the Road King in the next week or so. I can see if there are any codes stamped on them and let you know.

Has anyone replaced their C90's with other speakers and had favorable results?

D-Rock · **Posted:** Mon, Nov 30, 2009 3:59pm

Are these not Celestion CL-80's that Mesa has tweaked and raised the wattage by 10 watts? Just like their 70 watt V30's ??

No ! Its a G12-80 Mesa tweaked & raised wattage by 10 watts. Far superior to the CL80 !

I have a bunch of clips done with MC90's. I'll try and load some up.

Boogie mostly. IIC+, IV, or III's.

I put up a couple, one is Cookin Groove, the other is MC90 Rhythm.

I wouldn't say the MC90's are superior to the CL80's, in fact I prefer the CL80's by a small margin. I do know the prevailing opinion is that the MC90's are better though. The MC90's are thicker with more mids and a bit warmer. The CL80's are clearer with more bite.

I meant the original early 80's G12-80 are superior to CL80s. They really are :yes:

Never heard the G12-80's, can you describe how they compare to the CL80's and MC90's. I am a big CL80 fan overall

Don't have much experience with MC90s, thats why I'm trying to find out more about them.

CL80s are a continuation of the original 80w speakers, not a reissue by any means. Compared to CL80s (which I hated at first, but warmed up to after I really cranked them), they both have that clean, accurate quality, but the old ones have alot more British sounding midrange, very very in your face. So in your face that I did not like them in my front loaded cab, while the CL80 was fine in there.

Its just very bold, with a bit of that EV brassy hardness to it. Its the only Celestion I've tried that is more aggressive in the mids than a V30, but it has loads more top and bottom than any V30.

Thats why I'm hoping the MC90 will be close to it, as many accounts say the MC90 and old 80 watter are much closer to each other than either is to the CL80.

I have a pair of MC90s I can bring up with me when we get together if you'd like. That would give you a chance to hear them side by side with your G12-80s. I'd be curious to hear that as well.

Yes ! I was going to ask you that, cool :thumbsup:

My friend says Sun Dec 13 is good. Let's shoot for the same time. If you have a different time preference, let me know.

It'sa very balanced speaker that's great for cleans to mid and even high gain. The Electradyne 1X12 combo uses it and it's a big part of the tone. Of course it works better with some amps than others and the only way to find out of you like it is to try it with your amp, not listening to a bunch of guys on message boards telling you how great or bad it is, so don't take my word for it. Just do it.
