Thoughts on building a 4x15"

Discussion in 'Amps and Cabs [BG]' started by semborg, Aug 9, 2005.

  1. What do you think abou this? To use on stage where there often are live performances

    I'd suggest building it with the drivers all angled inwards, to save space. Kinda like the Marshall 4x15 & Sunn 4x15.
  3. you might as well nail it to the ground too while you're at it...

    it'll be to hard to transport.

    Why must we always think that big means heavy.

    Birch Ply
    Neo Drivers
    Sealed cab(for less ft^3)

    This could still be very portable.
    I say go for it. In fact, I think that it would be cool!

    It would be probably end up being a 2 ohm cabinet

    Build it like the Acoustic 408. Look it up. Two 15's facing front with a compartment in the middle, about nine inches tall, housing another 2 15's. One facing down, the other facing up, slightly offset from each other. These two speakers were actually housed above and below the middle compartment, firing into it. Just incredible sound. You can see a pic here. http://acoustic360.homeunix.net/products/main/408.html

    That thing would have low end for days, but you'd have to shell out cash for some pretty good drivers if you wanted anything but low end.

    Maybe build it kind of like a Schroeder with that port kind of thing.

    Thats a good idea!

    2 front firing 15's and 2 side firing 15's.

    Oh ya and alot of low end :D

    I think it would be cool, heavey though. I'm surprised peavey hasn't made one (a 4x15) I remember seeing an old pevey cab that had 2 10's and 1 118. Cost about 150$ probably weighs 150 pounds too. But ya keep us posted if you do build one!

    This is gonna sound dumb, but maybe have them facing in reverse. i.e. have the magnets facing the outside of the cab. This technique is employed by many other forms of audio such as car audio. Its used because apparently the bass frequencies are generated at the back of the speaker.
  11. Marshall 4x15's were not built that way. They look just like a 4x12 guitar cab only bigger, no low end, though.

    ...Nick Epifani built one for Vanilla Fudge's bassist. I was there when it was half way done a while ago. Definetly big & heavier than a typical cab of "convience"...probably sounded sick though...


    PS: Next time I'm in the Epi/Fodera area, I'll inquire about it...
  13. I think no.

    Despite the size and weight hassles, and despite the wrong tuning the 4x15 will no doubt have, the soundman at every show with PA support will hate you.

    When I do sound for the local kiddie bands with this much backline, I don't even bother micing the bass. They are always far too loud on their own, so I would have them turned entirely off anyway. These bands are typically 112 to 118 dB(A) at the audience position. Screamin', bleedin' loud.
