Steve: I'm interested to know the "spec's" for the 212RH Music Man speaker enclosure. Speaker brand? Intended use? Ohms? Watts? Etc. Thanks. | ||

Steve: I was hoping you'd have some infoarmation about this enclosure. Are you there/here? | ||

I'm here... right now that is. I saw your post but I was at work and didn't have any information with me (other than the info on this site's Model Chart). I was hoping you might find most of the info you needed on this chart (that is where I found it!). The "RH" (Reflex Horn) series cabinets were designed for either bass or guitar, but since this design was to acoustically reinforce the low-frequencies I think they had Bass in mind as the primary use of them. Contrary to popular opinion, there is less "specialization" in speaker drivers than is commonly held. There really aren't special "bass" speakers or "guitar" speakers, just drivers with different surrounds, cones, frequency responses, voice coils and power handling capabilities. Certain drivers may lend themselves more towards one application or the other. However, as long as you do not exceed the ratings of the drivers and avoid cone "break-up", the speaker can't tell what is driving it... it could be a CD player, a microphone a bass guitar or whatever. Consulting the model chart, it says that ALL 2-speaker RH cabinets are 4 ohms (two 8 ohm drivers in parallel) and rated for 130 watts RMS (no doubt to match the HD130 amps that would most likely drive them). The chart also indicates there was a version with 12" Electro-Voice EVM premium loudspeakers (higher power handling... maybe 200 watts or more, cast frame, real paint-pealers!) as well as the standard version with drivers that had 28 oz. Alnico magnets. My guess (unless someone else knows better) is that these drivers were either made by Eminence or CTS/Utah. Steve | ||

my 1977 130RH 2X12" uses eminence standard(code 67) hope that helps. tell you what these cabs rock the design is unbeleivable. | ||

Thanks for the confirmation on the speaker type. These cabinets ARE awesome, but they weigh a TON. Weight is an unfortunate side effect of a well made bass speaker cabinet! | ||

im using mine with a MM 210"130w guitar amp is it okay to drive the 2 10" and the 2 12" at the same time? im sure it is. the only problem is - wont the extension speakers be louder than those in the combo? i say this as i have not tried , i have the 212"RH cab sitting there with 2 blown speakers which i bought for about $200 aus. wich is a steal over here. now i have to get the speakers rebuilt when i get some more cash. though an extension cab really shows the potential of the old 130's. espiecielly a bass cab for guiar!!! what does reflex horn mean? and then what does HD stand for and mean?? see ya guys. thanks in advance | ||

I have an HD-130 head that I'd like to use to drive a 115RH (8ohms) and a 212RH (4 ohms). Is this possible? Will I need to have the 212RH re-wired to be an 8 ohm cabinet? How? Thanks, Tony | ||

You can run it just the way it is, but you will have a slight mis-match on the cabs, but really, I don't think you'll notice. THe outlets on the 130 are in series so your two cabinets will be in series and total 12 ohm. just put your selector switch on 8 ohms and you will be fine. The 2-12 cab may be SLIGHTLY dif in volume but I doubt you'll notice it. Mike. | ||

Thanks Michael, that is good news! Does that also mean that if I wanted to hook-up two different 4 ohm cabs, I would also be OK if I put my selector switch on 8 ohms? I thought it went the other way around - that if you have 2 4 ohm cabinets, the net effect is that the amp sees 2 ohms. Also, what would the ohms be for a 8 ohm and a 4 ohm cabinet together? Somewhat confused, Tony | ||

im pretty sure the 15 is 4 ohms bro therefore it would be 4 + 4 = 8 |
