Sign in to disble this ad
4x6" to go with a 15" combo? i was going to homebrew one, i could for about £70
Specs for each driver:
# Frequency Response Max:10kHz
# Frequency Response Min:37Hz
# Impedance:8ohm
# Power Rating RMS:75W
# Resonant Frequency:40Hz
# Sound Level SPL:88dB
# External Diameter:6.5"
# Power Max:150W  |

| | | the sensitivity rating isnt that great. but i know a 4X6 cabs exist: http://www.guitarcenter.com/Markbass...37-i1437922.gc
You should try and find a driver that has a higher sensitivty and maybe one that can handle more watts.

Is that max SPL listed sensitivity? Ew! |

Amp = 180w rms/300w peak into 4ohm
4x150 peak = 600 peak
then add the 15.... |

And if you do that, you only need one or two to match with a single 15. Four is more than you need. They'd overpower the 15, cost more, and weigh more than you need.
You won't need much power to drive a pair of 6" midrange drivers. But this setup would mean two cabs, two channels of power amp, and the crossover. Seems an expensive way to go to bump your mids...

Phil Jones are probably the best "small drivers cabs" around and they still fart out pretty easily with the lower notes that a bass can produce... |

If it sucks or provides poor final value in terms of cost, and/or performance, you'll know soon enough. Or not. But I'm guessing this will be a trial and error kind of thing since you haven't listed some of the more pertinent Thiele-Small parameters. |

I was thinking about getting some Phil drivers but i guess they are expensive.
I could use either 1 or 4 of them... |

Both get really loud but move about as much air as a good 210 when put together. No way I'd couple one with a 15" and expect it to keep up.
By the way, they also sound like a decent 210. You couldn't tell I was using a 4x6 or 2x8 if you didn't look.
It's definitely a fun build so don't let us naysayers stop you. I did it. Plus I only have about $50 per cab invested so I know I can sell them for costs when the time comes. |

| | Registered Bass Offender | | Join Date: Nov 2007 Location: Cambria, CA (Central Coast) | | | A 2x8 is probably still more than you need for mids. Also, you're now talking about a driver that's closer to the 15 in size. The original point is to use a much smaller dedicated mid driver, not something that's going to be close to the 15 in mids.
You could still consider your original choice of 6" driver, but you'd be crossing it in the midrange. So its purported performance to 37Hz is unimportant, since you'd never drive it down there.
Why a crossover? Because mixing different-sized drivers in the same frequency range often doesn't sound good.
