i was wondering if I get a second Orange 112 cab, will it be louder than just have one cab?

here's the specs of my amp: SPEAKER OUTPUTS: 1×8 OHM OR 1×16 OHM OR 2×16 OHM
 
Re: two 112 cabs

most cabs are wired in parallel if they have two jacks. you would want 16 ohm cabs for your amp since in parallel that will give you 8 ohms.

it wont make a ton louder but it will give a wider sound too. if you want a lot louder, get a more efficient speaker. of course you could get a new 1x12 cab with a eminence wizard 16 which is a loud speaker. is your current cab 16 ohms?
 
Re: two 112 cabs

if your playing outside at gigs alot of players recomend at least 2 speakers because outdoors seems to make your tone kinda one directional or small so players will try to use more speakers or 2 cabs to try to widen the tone even if its miked. I watched a gig outdoors last month and both guitarists used 2x12 combos despite the P.A. but neither one had front monitors ether so if you have front monitors you may not care but the average guy doesnt get real fancy so mikeing through a P.A indoors you can get away with it but a larger gig or playing outdoors or if the other guy in the band plays his guitar through a 4x12 cab your sound may get kinda lost unless you have another speaker to faten up your tone. It wont make it really louder but it does faten it up at stage volume and give it more ambiance.
 
Re: two 112 cabs

Two identical speakers in phase with each other will be 6dB louder than a single speaker. Every 10dB of level has the subjective equivalent of sounding twice as loud, so that's a significant increase in sound pressure level.

Every time you increase the sensitivity of a loudspeaker by 3dB, it is akin to doubling the effective wattage of your amplifier. Every time you double the wattage of your amplifier, you net another 3dB of sound pressure level.

Using these calculations, you can dial in exactly the pair of speakers that will be ideal for your situation. Or, you can just get a pair of Eminence Wizards lol.

You can read about the maths here if you like: http://www.sengpielaudio.com/calculator-coherentsources.htm

So if you have a single 95dB sensitive speaker and you go with two 98dB sensitive speakers, your total increase in SPL will be 9 dB, or just about double the volume level.

this is good stuff :haha: I have never seen this calculation before but it seems valid enough. good post.
 
Re: two 112 cabs

thanks.

i already have an Orange PPC112 with Vintage 30, which is apparently a sensitive speaker. It sounds good. I'm thinking of a second Orange PPC112 -- the same exact model. Widening, stereo, fatten, ambience anything helps. I'm gonna get an amp stand too. my drummer is loud and I can't hear myself. i mostly play crunch.
 
Re: two 112 cabs

If your main concern is all about hearing yourself above the drummer, then get the amp stand first and see if that solves your problem. You may find that's all you need because the sound can be directed at your torso and head instead of just blasting at your legs. The audience will hear you better too because if your amp is sitting flat on the stage, or even flat on a chair, a great deal of the sound energy is going directly into the stage floor instead of directly out into the audience. You may actually find you that can turn your amp DOWN a bit with a stand!

It also has the added benefit of being WAY cheaper than a second speaker.

LOL I did this too when I had a small combo amp and a guy in one of my first bands showed up to practice with a Marshall half stack. I ended up stacking several plastic milk crates on top of each other till I could get my combo up high enough for the drummer to hear it over his bass drum. The other guys half stack drowned me out till I got a 2x12 combo but stacking my 1x12 combo up off the floor using milk crates (although not high tech) really helped at the time.
 
Re: two 112 cabs

Yikes!!!

FWIW,I do have an ancient MF stand.

Far from great & pretty clanky,but better than nothing...
(or milk crates)

:)
 
Re: two 112 cabs

Yeah a stand is just better all around. More stable base and keeps your amp's center of gravity low. But the tilt-back is really what you are after... milk crates/chairs/risers don't offer that for you.

The calculator shows each "speaker" as a source. So, I believe that the theoretical 6db increase is dependent on the 2nd speaker receiving the same amount of power as the 1st speaker was/is already receiving. Not sharing the power between the two speakers.

Not that you stated or implied anything otherwise. Just clarifying, as I understand it.
