ficelles Posted August 14, 2011 Share Posted August 14, 2011 Played open air at Bristol Balloon Fiesta today (two sets with different acts)... arrived to find a vocal only PA so my rig had to handle the low end unaided... so ok we weren't required to be that loud but I must say my little SWR Electric Blue head into my home-build 1x10+1x12 cab rose to the occasion rather well, even to the extent of the engineer asking for it to go down a little when I had the loaner '63 P bass through it. 160W into 4 ohms is the most it can put out but that was an impressive 160W with plenty of headroom left. Mind you, you could have nicely simmered a casserole on the top of the amp over the afternoon... There has to be some difference in how SWR do their power ratings to other manufacturers, I don't remember my Ashdown 575W head being any louder through the same cab. Or maybe I hit some efficiency limit of the cab with the smaller amp anyway? ficelles Quote Link to comment Share on other sites More sharing options...
jensenmann Posted August 15, 2011 Share Posted August 15, 2011 Some day when my SVT needed some TLC I took my El. Blue with me and played it into the SVT 8x10". The band didn´t believe what was coming out of the cab. SWR did some magic to their poweramps to make them work with these 8x10"s perfectly. My former SM400s was another favourite of mine together with the Ampeg cab. Quote Link to comment Share on other sites More sharing options...
simwells Posted August 15, 2011 Share Posted August 15, 2011 I have got to agree with you on the power ratings of them, I used to practise in a room with one of the Mag 300watt 2x10 combos plus a 1x15 and my 160watt Workingman Pro combo was clearly more powerful.

I think there may well be a diminishing returns thing over a certain power level with 2 drivers... but anyway I do feel that SWR watts are somehow louder than Ashdown watts! ficelles Quote Link to comment Share on other sites More sharing options...
Kiwi Posted August 17, 2011 Share Posted August 17, 2011 IIRC 8x10 cabs tend to be highly sensitive with ratings around 103dB. The SWR amp I've owned plus others I've tried had scoopy colouring so that might work with the colouring of an 8x10 nicely I guess. Quote Link to comment Share on other sites More sharing options...
