I realise this is a similar thread posted a few months ago but the answered provided there dont really answer my problem - i think. What kind of volume should you expect is my question in relation to power and speaker configuration? I also have a TE 350W RASMX GP 12 head. i run a TE 300W quadbox and a TE 200W 15" speaker box - one of the half sized ones. Most of my gigs usually consist of in mid sized nightclubs and pubs playing coversongs where the pa does most of the work.The band consists of two marshal 100W + quads, drums, keys and vox playing mostly top 40 rock stuff. i've found that it takes quite bit of volume from my rig to get some clarity and punch into the mix. My problem is that i get a barking distortion when i run the whole rig all together at 3 to 4 o'clock. even there it just doesn't seem loud enough, and i don't get the low end punch im looking for. I've tried both speaker boxes on their own and get the same effect at 3 to 4 o'clock. the distortion rolls in, but not as bad as it is when they are in combo. The head is about 6 years old and was serviced last year. the quad box is a little older i think - if you know your TE gear its the model without sound holes seen in newer models, it has reds stripes and a horizontal port across the front. the 15" 200w is newer, maybe 2 or 3 years old. I'm not sure if there maybe something wrong with the amp or maybe i should lower my expectations of what kind of level of volume it should be able to produce with clarity. What kind of volume should i expect? What's the point of having a volume knob that goes to 10 when i can't go past 4 without distortion? If it is the power rating thats the problem, how much would you go for when shopping for a new head? In another thread i read that some amps 'clip' when running at 8 ohms. What does this sound like? could it be my problem?
