    Hey guys, ive been wanting to know if i could use two PA 2x15 speakers as my bass cabs. PA speakers get much louder from what i heard, and keep the low end too. Theyre also cheaper... What do yal think?

    There is a member that uses two Behringer powered cabinets as his bass rig.

    i know a guy who uses a PA speaker as a bass cab (1x15 + tweeter)... doesn't sound half bad.

    Don't see any reason why it wouldn't work. Stefan Lessard from DMB used to used Meyer powered PA cabs for his rig.

    The only thing I can think of is how far away you'll be from the speakers. I say this because PA speakers are designed to sound better the further away you are from them. If you're going to be standing right in front of them, they may not sound as good as they will from a couple of feet away. Now keep in mind that's a very minor nit pick, but it's worth considering.

    I use Meyer PA cabs and couldn't be happier! Best gear I have ever played through period!

  7. There are certainly benefits to using a PA cabinet. For instance, the horns are much higher quality than the cheap piezos typically found in bass cabinets. For another, if you’re patched into the house system, you’ll have a better assurance that your sound from the stage is a closer match to what’s coming out of the PA.

    The downside is what modflea mentioned, that PA cabinets are designed to sound best some distance away, so what you hear on stage may not sound so good to you. However, you could compensate for that by getting a floor monitor that matches your main cabinet and throw it down in front of you (often manufactures have both house and monitor speakers in a model line). That way you could get the best of both worlds.

    Well actually, i was plannin on just usin the input from my head rahter then micing it. Im not lookin for anything to fansy either. I just wanna have a nice 2x15 cab PA style. This is the first time ive conidered a PA, it just slapped me in the face over night that maybe i should try one. Also, whats so bad about piezos?

    I use a Meyer Sound UPA-1P powered 1x12 w/horn,USW-1P powered 2x15 sub,and a USM-1P powered 1x15 w/horn wedge monitor.
  12. I like the yorkville pa cabs. i have the 12's unpowered. thye are medium throw but work well as floor monitors too. inexpenisve. lightweight material. not a plastic, but a hi-tech hardened foam or something.

    Here's a twist. I couple of months ago I ran into a gig problem and wound up using my Euphonic CXL112 cabs for the PA (vocals and all). Go figure.

    To use a top notch PA cabinet for bass is possible and it sounds really good. I would question if it is cheaper.

    Most moderately priced PA cabinets are not built to but out a huge amount of bass. For example, the Yamaha Club series S112 speaker has a frequency response of 60 Hz - 16 kHz (-10 dB). For all intents and purposes there is no low E coming out of this cabinet. It still sounds halfway decent because they make a hump in the low mid range so the cabinet sounds round and full. This is O.K. as long as you have good room acoustics. If your room resonance happens to coincide with that hump you'll have all kinds of trouble.

    By comparison, the -10 dB point of the Euphonic Audio CXL112 is at 27 Hz!!!!!!, the -3 dB is at 45 Hz, the -6 dB at 38 Hz.

    A higher quality speaker like the Turbosound TDX 112 is specified with 60Hz - 20 kHz +/- 4 dB.
    The TDX115 is 45 dB at -4 dB, so that speaker is almost there.

    The TDX 115 is about $600, not much cheaper than the EA (as cheap as $630), and the EA is lighter and easier to transport.

    I draw the conclusion for myself that yes, PA cabs work, and they sound much better than many cabs specifically made for bass. However, you need really good ones to get the bass performance needed.

    The EA CXL112 sounds like a PA box, too, but its output is optimized for what bass players need, so I went with the EA.

    Haven't messed with speakers in a while. I've always heard bass and PA speakers were made differently but couldn't remember what it was if I ever knew. I thought reading this thread might refresh my memory.

    I've got a pair of L'acoustic speakers that I know are PA and have run bass through them and they sound fine - even up close. When I used to read through JBL and Altec applications for speakers I don't recall any of them stating use for PA and musical instrument, although they would specifiy Bass, keyboard, and steel. Regardless, I've never heard of any damage that would result in doing so.

    Bottom line I guess is if it works and you like them.

    Hmm, what about the other way around? Could a 1x15 maybe be used for other applications like keyboard or voice (with horn preferred, of course) or even something like a kick drum amplifying PA speaker?

    Yes, I know a drummer who occasionally uses a Behringer keyboard amp/pa combo for either electric drums, or to get his kick and snare louder. I think its something like a bx1200.

    Pretty common for Keyboards to run through bass rigs in general, not just 15's. It's my understanding the reason 5 string basses even came about was becuase, once keyboards became standard, an overlap in lower frequencies was causing a problems. I used to run a strat through an old Fender Bassman practice amp for that matter.
