Help with Bandit 112 extention cab ideas

Postby ninjasword71 » Wed Jun 19, 2013 3:05 am

First off, I'm not young, I'm stubborn and like to build. I have a Bandit 112 silver stripe and want to build a cab for it. I would like a 4 speaker one or 3 if anyone has attempted it. I know the output is 100w but wouldn't that mean I need no more than 4-30w speakers? 4x30=120w correct? I try to think outside the box on the most part. Does it work to do a 3 speaker cab? I want to end with 8 ohms if possible. I don't gig right now but just want more volume. I am more confused with the series/parallel debate now that I checked it out online. Anyone have a proper wiring diagram or one for a 3 speaker system? Thanks for any help I can get

I believe your extension cab will be handling 50 watts and 50 watts on your amps internal speaker. Without the extension cab your amp puts out 80 watts. Your probably better off to build a 4x12 if you want to end up with 8 ohms. 4- 8ohm speakers wired in series/parallel. You need to wire 2 sets in paralell and then wire those set together in series to end up with 8ohms.

Thank you for the reply and a nice straight forward answer. Not brand, but what watt speakers are best for a 4x12 @ 50 watts? I don't want to under power them too much and don't want distortion when cranked. My amp or effects unit will handle that.

Choose whatever speakers you like that will handle the power output. There is no such thing as underpowering speakers. I've run 300 watt Marshall cabinets with 1 watt amps. I generally recommend 1.5 to 2 times the speaker power handling.

Simply put, 30wx4 would work too with great sound or should I shoot for 50w or higher? My reasoning is that 30wx4=120w which is 70w in the safe zone or is this wrong? I don't want to buy speakers with way too many watts if I don't need to. I understand that guitar speakers are different in that they have to handle squeals and thumping lows quickly.

Jensen mod 12/35s. They are reasonably priced and are really a great all around speaker.they also sound really good in the transtube bandits. There are more expensive speakers out there but that doesn't mean better. Wgs makes some nice makes some nice stuff I hear.

I built a 4x12 with the Mod 12-35 speakers and they do sound great. I've used them with a Peavey Windsor 100 watt head and a Mesa Heartbreaker 100 watt heat with good results. They have a lot of lows. They also have a lower spl (around 94 I think) so you can run the amp at a higher output before getting overly loud. Also the small magnets make for a light cab.

To build a 3x12 cab you would need two 8 ohm speakers and one 16 ohm speaker. I would make sure that the spl rating would be really close if mixing speakers so they will all have the same perceived sound level.

I made a custom baffle for my bandit . 3 jensen mod 8/20s all of which are 8ohms. I wired two in parallel making it 4ohms then wired the other 8ohm in series making it a total of 12ohms. The only problem I found was the single 8ohm was twice as loud as the two in parallel.So I wired a 8ohm 20watt resistor across the poles of the single 8 ohm speaker and it balanced it out.while the amp now sees an 8 ohm load and puts out 80watts only 60of those watts are being applied to the speakers.the other 20watts are going into the resistor. I only use it for home use. But it sounds amazing . Like a mini half stack. For an 8" speaker the jensen mods sound great.and very good bottom end not boomy at all . I suppose the size of the bandits cabinet has some thing to do with that :D

2 jensen mod 12/35 8ohm in parallel and one 12/35 4ohm (if they make it) in series adds up to 105 watt 8 ohm cab. But the single 4ohm may still be louder thand the two 8ohms in parallel. :(

80 watts @ 8 Ohms versus 100 watts @ 4 Ohms = Minimal additional volume

Adding Speakers = Push More Air
