I have a 2x12 recto with 2 v30's and am considering swapping one out for a C90.I had the C90 in a lonestar combo special and tried the mark v head through it.I liked it but sold the lonestar soon after.I was considering getting the 1x12 open back wide body with the C90 but swapping a speaker is a lot cheaper.Thing is the lonestar was open back so im not sure how the c90 will sound in a closed back recto.Has anyone tried this?Cheers
 
Might be worth searching for Roadking 2x12 comments since that's the speaker mix it comes with (although the MC90 side is semi-open).
 
I was thinking of doing the same thing, but I have to convert my
Mark V to a head first and I'm still waffling on that as well :(

I recently rehoused the MC-90 in my Combo into a homemade Diagonal 2x12 cabinet. I went with a V-30 for the other speaker, and so far I love it. It sounds WAY bigger than the Combo did on its own. And by bigger I don't necessarily mean a big increase in volume, its more in the way that the cabinet fills out the room with sound, it sounds much fuller and wider than the combo.

Because the MC-90 is known for having a lot of low end, I went ahead and placed it on the Bottom and I placed the V-30 in the Top position. This seemed like the best configuration, so that the speaker with the most audible Mid-range would be higher up off the ground. I may swap them at some point to see which configuration I like best, but right now I am really enjoying the sound. It seems like having the mix-matched speakers in the cabinet also did a lot of EQ work for me. I don't find that I need another EQ in the loop now, or at least I don't need it in order to get a tone that I really enjoy.

Hi,just wondering how this config is working out for you?Considering replacing a v30 with a C90 as one has come up for sale.Cheers
 
I've been playing with different speakers and cabinets with my Mark V.

2x12 recto vertical with C90 + V30: Maybe more low-end, but the V30 seems to dominate
2x12 recto horizontal with CL80 + Creamback 75: Way more low-end, no more shouty mids, but the Creamback gives loosey-goosey lows along with the extra mid content. Good feel and tone, though.
2x12 recto horizontal with two G12K85: Lots of lows and restricted highs, no mid hump. Nice, polite, maybe a bit too-well behaved. With the Mark V I can still drive this and EQ it to sound any way I want.
2x12 3/4-back with V30: This is an old cab, so the V30s are very broken in. I found it to have a good mix of lows and highs, and not very shouty in the mids. Great balance. Still had some breakup, but not as much as in the closed-back.
2x12 3/4-back with C90: Monster lows, well-balanced mids and highs. No breakup, but a little sizzle.

Overall, the closed-back recto cabs kill off some ultra-lows and have a low-mid punch that the open-backs don't have, while the open-backs have way more lows.

Interestingly, I have found that the EQ does a really good job of making the different speakers sound similar. By upping the 80Hz and dropping the 6600Hz, I could get the 3/4-back with V30 to sound a lot like with C90. However, the closed-back cabs still have limited low-lows and more punch.

So far I am really loving the two speaker mix. With the C-90 from my combo I knew I didn't need any more low-end so the V-30 filled in the frequency gaps I had previously used another EQ to fill out, now-a-days I run the Mark V straight-up more times than not. I throw the EQ in to further tighten up my tone on rhythm playing in lower tunings but that's about it now that I have the 2x12. I think a closed back 2x12 just handles this amp better than the single speaker combo configuration ever could.

I also would say I have to agree with Elvis that the EQ options within the Mark V kind of let you dial in similar tones across the speaker spectrum. But I also feel like having a mix of two types of speakers does a lot of extra EQ work for me, when I do run another EQ in the loop , its basically an extension of the Graphic EQ Shape I use on the Mark V I just bump a few spots in the mid range here and there to make up for my ever so slight scoop of the 750 slider (my ear is use to hearing a big mid-bump in the 3khz area, don't know why). My EQ also cuts anything from 80 and below, so I can bump that 80hz slider up for a big bottom-end without getting flubby.
 
Hi BrownieD2W,

ive just been considering swapping out the Mark V combo speaker with one of the V30's from my vert 2 x 12 cab but was informed of the 8ohm and 16ohm mismatch between the two speakers, how did you get over that?

thanks,

Wayno.
 
Awww maaaaan that combo looks amazing.The black look is so boring ha.Wish my head looked like that

Thanks, to be honest the custom finish was just a lucky strike. I bought it used two years ago and was the only one I could find back then, I live in Chile 8) .

The impedance mismatch is the less of your problems, the v30 is a 60w speaker while the c90 is a 90w speaker, since the mark has a maximum output of 90w, I'll think twice before connecting to a speaker incapable of handle that power output.
 
Hi Demon Of The Fall,

Very nice Mark V you got there. I would assume that the V30 and C90 speakers wouldn't "see" a 90w signal as it would be split between them. To what percentage each speaker would get i don't know, depends on the ohms, gues theres a formula to work that out.

Think im understanding that BrownieD2W has done this?
 
General rule of thumb in a two speaker cab is that you double the wattage of the lower power speaker. I have a cab with a g12h30 and a v30. The h30 handles 30 watts and the v30 handles 60. So since they are both the same ohms and wired in parallel, the cab is rated at 60 watts, or two times the g12h30's 30 watt rating. A v30 and a c90 would rate approximately 120 watts of power handling, or twice the 60 watts of the v30.

I'm sure this is a vast oversimplification of a complex mathematical formula, but it's close enough for government work and guitarists. :mrgreen:
 
Thanks Monstercastle,

Think im defo gonna give this a tryout then. Doubt i would have too many issues with power handling anyway as i never have the Mark V run flat out, it's ridiculously loud at less than half on the master volume pot!!

Thanks for the input guys.
 
I would recommend the Celestion G12H-7516 to be paired with the V30-16 in a 2x12. I have done this with my RA100 Combo and the result is incredible. The Mark V also sounds great though this combination.

combining an 8 ohm speaker with a 16 ohm speaker will result in a 5.3 ohms DC resistance. Best to use the 4 ohm output if you do this.

Monstercastle cleared up some of the confusion on this point. Just adding my two cents because I wouldn't want people running around spreading misinformation. There is absolutely no reason a 2x12 Speaker Cab with one 90w and one 60w speaker can't handle a 90w amplifier. Both speakers will pull approximately 1/2 of the wattage coming from the amp, half of 90 is 45, that means each speaker will only receive a maximum of 45 watts and that's only IF you were silly enough to dime the gain, master, and output volume of the amp. As long as both speakers in the cabinet are at a wattage above 1/2 of the amps maximum output you're safe, which was the main reason I went with the V-30 for the second speaker instead of a 25 watt Greenback or something similar.

And just to clarity both of my speakers are 8 ohms, I didn't feel like trying to manage the mismatch so I just bought an 8 ohm V-30 to go with the 8 ohm C-90 from the combo, and I wired them parallel for a ~4 ohm impedance.
 
Thanks for the info guys.

Definately going to try this out as soon as i get a chance. Found some 100w rated 8 ohm resisters on google so will hook one up in series with the 8 ohm C90 then run that in parallel with the V30. That will give me a 8 ohm load to hook up to the Mark V. Looking forward to this :)

Thanks for the info and sharing your experience with me.

Wayno.
