Hello. I have a 100 series 1x15 with a 4 ohm 200 15" Crate speaker in it that I enjoy thouroughly, but I would like some more volume out of it, so I thought, why not turn it into a 2x12? I've heard of this being done before, so all I would have to do is remove the speaker and harware from the baffle board, unbolt the board, make a new one with the 2x12 cutouts (and of course ones for the ports), cover it in grille cloth, and reinstall all hardware and new speakers? I love this little cab, but I know it can get louder with a 2x12 setup since it wasn't really designed to be a 1x15. For those who know, is there a huge increase in volume? Mine originally had the 16 ohm CTS in it (which I put in another cabinet) so I put in a 4 ohm speaker, but would there be much difference between a 4 ohm 1x15 or a 4 ohm 2x12 volume wise (i.e. is it worth all of the work)? Thanks!

Its designed to for eight ohms. Hence two 16 ohm twelves. You will push a bit more air with the two twelves. But I would not expect a radical volume increase for the work you'll be putting in it.

The thing is it gonna a preceived volume increase and I have always been told that 3Db is it. I don't really think that you'd gain over 3Db just by changing to 2x12's. You would only be gaining 7 more inches in speaker area.
True it moves more air. But not that much. Sometimes its just hard to tell a small increase in volume. Now you might get higher wattage speakers and pump the volume up by increasing the power of the amp that drives them. Perhaps both of those would get you what you want.
What I mean by this is that a 200 is preceived volume increase but it grows more apparent when you add a second cab to it because it is now getting the 4 ohm load it wants to see plus twice as much speaker area. You would not be doing any one of those. You already have a 4 ohm load. So you won't gain anything there. I would expect a little bit of and increase but not miracles from it.
Are you playing bass, guitar, keyboards or what thru it? If you are playing guitar you should already be there where you need to be. You might be. Sometimes guitar players are louder than what they think that they are. I used to always think that I needed more and more too. But the truth was after recording the group live I knew that I did'nt anything. You might borrow a wireless system and walk around with it some.
Now bass is a different thing. It takes a whole lot of wattage to push those lower frequencies and lots of headroom to make them clean. If you are playing bass and the rest of the band is drowning you out. Then it may be time to spring for a big cab and a big head.
You might think about keeping the 1x15 for rear room projection and getting a 4x10 cab to add to it if you are playing bass. You can then add a more powerful head too.

My loudest set up is and 800 watt power amp into eight fifteens. But takes four cabs. I use that with a small Pa board as its preamp. My next loudest is my 450 watt Ultra bass into four fifteens. A mere two cabs.
For something small and still be very loud. I suggest the SWR series with 2x10's. I believe it has about 300 watts. A buddy of mine has one. Its small but very mean and a very compact amp to move.
In Kustom if you want to play that loud. I'd suggest you trade the 100 cab with some one for a 150 cab with 2x12's. In Kustom cabs the orginal 200 and 100 series cabs slant as the height of the cab increases. That decreases the internal room in the cabs. But Ross fixed that in the next series.
When he did the next and his final series the 250 and 150 series. They were not slanted but just the same width all the way up to the top. There some some pic's of a lot of black amps filling up a back yard in a topic above. Look at those and its easy to see the difference in them.
This gives the 250 and 150 more internal volume and they can will get much louder with more power added on them. You would just have to put in the proper speakers to match whatever amount of power you use.
As Steven was saying earlier too once you get into that area then get the most efficient speakers you can afford too. Let us us know your results.
