inexpensive 12-18\" raw sub speakers???

Anyone know where (online) to purchase a decent guitar dual voice subwoofer speakers (raw, no cabnetry) in either 12, 15 or 18\" diameters?
I'm hoping to find something less than $100.00
Now while a car audio sub would probably work, I was told not to use a speaker with a foam surround as it'll just blow out the cone because the foam surround isn't strong enough.

The reason I'm looking is to add a sub across the speakers of my Spider 3 150 watt stereo combo amp. While I love the sound(s) of the amp, there's just not enough bottom for my taste.

My (hopeful) plan is to rebuild the combo into a separate head w/ 2x12 cab with (perhaps) the sub bottom firing.
Thanks in advance!

  • I have had good luck with this company. They sell raw speakers. Here is the link: http://www.seismicaudiospeakers.com/SearchResults.asp?Cat=21

    Another place that seems to have good prices: http://www.parts-express.com

    Good luck.
  • You don't want a Dual Voice design. Not meant for guitar. I'd build an ext cab since the voicing of L6 cabs are designed to \"fit\" the modeling. For guitar, a subwoofer can extend some low end but don't expect too much. Guitar is not normally in sub territory, so you may have extended bass on some areas of the fretboard but it would not necessarily be what you are looking for unless you play a 7 string.

    You could try a 12\" bass speaker or one used in a PA cab. Those are going to have more low end but also tap the mids. Might even provide the more transparent speaker class requirement of the modeling amp.

    This one for example would fit the area. Another point is most guitar amp speakers used in modeling amps do not have a brilliant sensitivity spec. They are not meant to. This one is relatively a mid point, but again has the extended bass response you might want.

    I've modified a few cabs with these for 7 stringers and baritone players:

    With the above design, it has higher efficiency and extended midrange. Even at 150W rating, in a neo design is better since it's much lighter and you probably won't require 150w output.

    Also look at the kappa and delta series from Eminence. Goldwood is a better budget speaker than PIO, PYLE and others common to automotive apps, but not really for guitar products. A step up from Goldwood is the beta and kappa series.
  • One other note-

    Modeling users have liked an option of having a coaxial speaker like the one below. In a simple stereo 2x10 cab, this one works very good.

    The advantage of coaxial drivers is it extends the hf range and offers low freq utility at lesser powers. Transparency is also offered in this design plus it will conform to speaker compensation usage and simple full range requirements of the GNX4 for mp3, drums and so on and it won't sound so trash can lids when drum machine is used in a guitar cab.

    Many good KB amps like Yorkville Sound use coaxial drivers. You could add a tweeter but you won't really need it unless you want \"ice picky\" highs.

    I haven't found a good 12\" version at budget costs in this design. There are plenty in the +$150 range with better specs as well.

    Edit- here is one in the 12\" version

    High power capacity, but also look at the efficiency rating and no crossover is required.
