grayn Posted January 12, 2011 Share Posted January 12, 2011 I recently got a Roland Cube-100. Basically becasue I really liked it's sound and for a small 1X12 combo, it's pretty loud and deep. Obviously it'll struggle in louder situations. Initially I thought of getting a 4 ohm ext cab (1X15 or 2X10). As the speaker output says "maximum 8 ohms". Then I though, for that money I could just get another Cube-100. Then having 2X12 and 200 watts. Does this make sense, or should I just get a much larger combo, when required?

This value is the result of the internal speaker plus ext cab working together. It could be stated in a clearer way by Roland though. Seems to me that the amp itself is putting out about 60W with it's internal driver and a extension cab could be a better and lighter solution to get 100W of sound. Adding a second cube wil give a bit more power (120W) but also more weight! Quote Link to comment Share on other sites More sharing options...

Line out from one into the input of the second one? A Y-splitter to run the signal from your bass into the inputs of the two combos separately?

guylewis Posted January 12, 2011 Share Posted January 12, 2011 I used to have one of these and my impression was that it is 2 x 50 watts into one speaker and splits it 50w/50w into two speakers . . . if you see what I mean. I built an 8ohm extension cab for mine and when using both speakers it was "fuller" but not much louder. Nice amp but heavy for what it is and I eventually went down the route of "separates". There's quite a few threads about it on TalkBass btw. Quote Link to comment Share on other sites More sharing options...

I wouldn't call that heavy. Mind you, I am surprised at how light stuff like Mark Bass is. Separates may be an alternative, I should look into.

Nobody worries about maximum impedance - it's minimum impedance that'll fry your amp... If you're going to add an extension speaker then you are looking for a 100W 8Ω cab. If you start hanging 4Ω cabs off of it then you will definately be in the market for a new amp! Edited January 12, 2011 by icastle Quote Link to comment Share on other sites More sharing options...

I guess you were attempting humour but this is a decent, small combo.[/quote] Sorry buddy, it was my attempt at humour in regards to the combo being decent. Roland make crackin combos. I was being serious about using a 4 ohm cab as the max load all in for your combo would be 4 ohms & run at 8 ohms without an ext cab. Adding an 8 ohm ext cab would make your amp run at 4 ohms, adding a 4 ohm cab would make the load 2.66 ohms thus causing the amp to overheat (ohms kinda work the opposite from what you would think on first approach). Have a look at the stickies in the top section of "amps & cabs", I'm sure there's a full explanation of how it all works. Quote Link to comment Share on other sites More sharing options...
grayn Posted January 13, 2011 Author Share Posted January 13, 2011 Thanks guys. The more I think about it, the more I am inclined to keep the Roland for practice, and small sessions and get a larger rig for when it is needed. I really like the Roland and it's tone but there's only so much you can get from a small combo, like this. Quote Link to comment Share on other sites More sharing options...
xgsjx Posted January 13, 2011 Share Posted January 13, 2011 Have a try on the Roland D Bass combos & see if it's a similar tone. They can be gotten fairly cheap nowadays. Quote Link to comment Share on other sites More sharing options...

That was a very decent combo, with a sound that really walloped you. Very loud, for a 2X10 combo. It could keep up with some loud backlines.

King Tut Posted January 13, 2011 Share Posted January 13, 2011 I think the correct impedance ext speaker to use depends on whether the output is wired in series or parallel - I've got a feeling that these are wired like the nemesis combos - which would make it OK to use with a 4 ohm cab. Can't be sure though. Quote Link to comment Share on other sites More sharing options...

xgsjx Posted January 13, 2011 Share Posted January 13, 2011 Oh, looks like they've stopped making them. I nearly bought one before I got the MB combo. They come up on here from time to time 2nd hand for @ £350-400. Tho there's a good selection of combos (or amp/cab set ups) in this price range to try out.

Muzz Posted January 14, 2011 Share Posted January 14, 2011 (edited) Yep, I can recommend the D-Bass, too. Really only available second-hand these days, but they seem not to be too fashionable, which means they can be had for a bargain - I paid £300 for my D-Bass and £250 for the 115X. There's a pair on Ebay at the mo. Very, very loud in combination (660w) and pretty portable, too (about 50lbs each and they've got wheels). Plus, they stack, too: essential for intimidating guitards... Edited January 14, 2011 by Muzz Quote Link to comment Share on other sites More sharing options...

grayn Posted January 14, 2011 Author Share Posted January 14, 2011 I'll keep an eye out for the D bass combo but may still splash out on a Mark Bass combo. No rush, for now. I was thinking, it's a shame you can't get powered bass cabs. Use your little combo for getting tone etc and have a cab with say a 200watt power amp, when more oomph id needed.

Muzz Posted January 14, 2011 Share Posted January 14, 2011 (edited) Erm, the D-Bass 115x IS a powered speaker - 330w, 15" and tweeter. Could be the ticket...and they're even less fashionable than the main combo, so if you see one for sale on its own, you could be quids in...
