isteen Posted September 13, 2014 Share Posted September 13, 2014 Ohm, I feel the headache coming on already. Two cabs at 4 ohm, that's trouble, isn't it? Since my amp (I think) can't handle 2 ohm, there is no way to plug in my 1x15" and 4 x10" (both rated 4 ohm) at the same time, just one of the cabs, right?

Dad3353 Posted September 13, 2014 Share Posted September 13, 2014 Right. That said, it is technically possible to have a box made up into which the two cabs could be plugged in as a 'series' connection. The amp would 'see' 8 ohms. Don't try this at home if you don't know what you're doing. Why would you want to connect both at once..? Simply curious, or a real problem needing solution..?

[/quote] Electrically, no, they just need to be connected in series rather than parallel. That means a box or cable designed for that specific job. Sound wise though, I'm not so sure. I think there are acoustic issues with running that kind of setup without a cross-over. Of course, you could always have a crossover made up, so different signals are being sent to the 1x15" than the 4x10" speaker... then it would behave like one giant 4ohm speaker cabinet.

[/quote]Not really. You use a crossover when one speaker is for lows and one is for highs. Electric bass tens, twelves and fifteens all operate in the same bandwidth, so there's no point in a crossover. For that matter there's no point in using them together either. A fifteen crossed over to a six or eight inch midrange is logical. A 1x15 used with a 4x10 that goes just as low and has more driver cone displacement is illogical.

I was guessing both cabs would be louder that just the one alone Quote Link to comment Share on other sites More sharing options...
Dad3353 Posted September 13, 2014 Share Posted September 13, 2014 Well, if you know how to solder and can rustle up a couple of jacks, sockets and cables, you could 'lash up' something just to try it out; it's not rocket surgery. What amp is it..? I'm not sure that you'd get extra loudness, but that depends somewhat on your amp's power into 8 ohms. Quote Link to comment Share on other sites More sharing options...
Bill Fitzmaurice Posted September 13, 2014 Share Posted September 13, 2014 [quote name='isteen' timestamp='1410640206' post='2551599'] 410 for the punch and power + 115 for the low end and deep bass tones.[/quote]That's the usual reason given, but it doesn't work that way. Fifteens don't go appreciably lower than tens, and even if they did you'd have to use them on a one to one ratio with the tens to equal what the tens are putting out.

Salt on your Bass? Posted September 14, 2014 Share Posted September 14, 2014 (edited) Op, if your Amp is 2 ohm stable then you can run both 4 ohm cabs at the same time, if I've read your first post correctly. If it only runs to 4 ohms, then you can only run one, or revert to jiggery pokery Edited September 14, 2014 by Salt on your Bass? Quote Link to comment Share on other sites More sharing options...
chris_b Posted September 14, 2014 Share Posted September 14, 2014 What amp and cabs do you have? Do you really need more than a 4 ohm 410? Quote Link to comment Share on other sites More sharing options...
isteen Posted September 17, 2014 Author Share Posted September 17, 2014 (edited) I have a Warwick WCA 410 (400 watts at 4 ohm) and a EBS Evolution 115 (400 watts at 4 ohm), plus two different heads I'm using ( a GK MB200 - 200 watt at 4 ohm as well as the 550 watt backup, (Behringer BVT 5500).Will check out the Warwick cab with the small head tomorrow along with a band. [i]I actually got the Behringer pretty cheap, but surprinsingly it doesn't sound all that bad[/i] Edited September 17, 2014 by isteen Quote Link to comment Share on other sites More sharing options...
