My bass Rig is in reality a Full Range Bass PA System. With the frequency response and SPL's it has, I could easily use it as a PA system and it could do that at even higher SPL's than when used as a bass rig due to the tremendous power required to reproduce a live bass guitar as compared to other instruments.
And you are right about increases in volume being a logarithmic function. I had to learn to use formulas to figure out if the person in the 2nd row experienced 115db SPL, then how much loss of SPL would there for someone in the 100th row 200 feet back and what would the SPL be there and you have to use a logarithm in the formula to figure that out. It takes 10X the power to make something sound twice as loud. But I have given up on trying to explain this stuff to members of a band I am talking to about playing for them. They never understand the physics of it. I wouldn't say I have an unbreakable headroom with my system, but I can't imagine ever having to push it to it's limits. But try to tell people they are more likely to damage their speakers with too little amplifier power as opposed to too much and they think you are out of your mind.
And people always say why can't you just show up with a Mexican built Precision Bass played through a 1X15 Peavey combo amp. Well, if that's what they want, I'm probably not the right person for that band.
Are you asking me if I know specific amps to use that are between combo amps and full concert rigs like mine? While I read a lot about amps that are out there and available, I prefer to purchase the drivers I feel will do the best job for what I intend for them to do and then design my own cabinets to put them in. And I do pay attention to mfg. suggestions for internal volume, resonant frequency and square inches of shelf venting or porting.
What are you currently playing through?
I know I have some ideas I would like Charlie Holmes to try with his system. He has a series bass, 2 F1-X pre-amps, 2 power amps and 4 cabinets. I want to try configuring his system so each pick up's output is amplified in a separate bi-amp configuration.
And how did showing up with a professional sound system with a roadie to move it in my own van, have the best type of bass available, (Alembic), and knowing the material better than the other members of the band and having no ego or attitude become grounds for being fired?
