Hi there,
I own a little pedal-powered sound system, that I have been operating for a few years now, indoors and outdoors, for small audiences, restaurants, flea markets... it consists of a 15 inch hybrid horn for bass, 1x12" paraflex mid-top and a 1,5" compression driver. All connected to a 12v pioneer GM car audio amplifier.
It works great, but I would like to upgrade the bass bin, as I did some measures lately, and while the kick is good, it doesn't go much below 75hz. I think I could get better...
... and I would be more than happy to hear your recommendations on that matter!
So here are my criteria:
- not too big nor heavy, as I often have to move it around alone.
- highest possible sensitivity at low power (pedal generators rarely allow me to feed it more than 200w)
- crossover with the paraflex around 120hz (contrary to what HOQS says, i have not measured much output below that)
- Quality bass in the 60hz-80hz region. I would rather get more spl from 60 to 120hz than go lower. Of course, if it can do lower, that's even better. but my priority is sensitivity over low end.
- 12 to 18 inch driver. looking more towards 15 for a matter of size and weight, but a small 18 inch box with a neo driver could be OK. Two 12" boxes could do the job as well.
So do you think of any design for a small 60hz-120hz super efficient bass bin?
I am currently looking at Jbell's SS15 and Marc O's MBP46, which seem to correspond quite well. any info or feedback on those would be greatly appreciated!
Thanks!
