throwoff Posted May 11, 2010 Share Posted May 11, 2010 Seen a steal of a 6 ohm cab going but I don't think I ever seen a 6 ohm head! Recommendations needed BC'ers! Cab is 900W power handleing (1200 max) Quote Link to comment Share on other sites More sharing options...
crez5150 Posted May 11, 2010 Share Posted May 11, 2010 An 8ohm head that will output 4/2 ohms will suffice Quote Link to comment Share on other sites More sharing options...

crez5150 Posted May 11, 2010 Share Posted May 11, 2010 no no... just one output.... What amp head have you got? Quote Link to comment Share on other sites More sharing options...
throwoff Posted May 11, 2010 Author Share Posted May 11, 2010 Dont have one! I will need to buy something to go on top! Quote Link to comment Share on other sites More sharing options...
crez5150 Posted May 11, 2010 Share Posted May 11, 2010 right.... well normally it will say something on the back of the head stating what the output impedance is.... it should also tell you what the min impedance is that the head will run down to... so might say something like - 400W @ 8 ohm/ Min impedance must not exceed 4 ohm.... which case you'll be fine... just use your ears when cranking the head Quote Link to comment Share on other sites More sharing options...
Alien Posted May 11, 2010 Share Posted May 11, 2010 Look for an amp that puts out between 200 and 1000 Watts into 4 Ohms. I know that looks like a huge jump from 200 to 1000, but believe me, it won't make much difference in the real world. You'll get about 90% of that into a 6 Ohm load, and your amp will run cooler. Other than that, look for an amp that's got the features you want. A Quote Link to comment Share on other sites More sharing options...
throwoff Posted May 11, 2010 Author Share Posted May 11, 2010 Im looking at the Warwick TubePath 10.1 1000W into 4 ohm sounds like it will do the job nicely Quote Link to comment Share on other sites More sharing options...

SS73 Posted May 11, 2010 Share Posted May 11, 2010 Measure the Ohms yourself with an Ohm meter, my 410, 8 Ohm cab is actually 6.2 Ohms. Your cab may be higher or lower, but when you know you can make a better choice, which way to go. Quote Link to comment Share on other sites More sharing options...

You'll just get slightly less watts into the cab. You'll never be able to hear the difference. Quote Link to comment Share on other sites More sharing options...

Impedance varies according to, among other things, the frequency of the signal sent through the speaker. Quote Link to comment Share on other sites More sharing options...

Might cause fun with crossovers I guess. Quote Link to comment Share on other sites More sharing options...
