I got a quick question regarding subs and their possible different applications.

Has anyone in here tried using any standard car audio sub in a speaker cabinet built for a guitar player?

A buddy of mine and I were mulling it over the other day (we both play guitar). Neither one of us wants to go out and buy a stack (two cabinets) at $1000 each.

Obviously, the building materials arent all that expensive, depending on what you use. Most speaker cabinets are made from 3/4" MDF (although some use birch - Marshall). The speakers are obviously where the cost comes from. Using the Marshall example, inside are Celestion speakers of various models.

My question stems from ... can you replace those speakers with any number of other speakers?

Thanks guys.

im gonna say probably. just use something efficient, something that does not require lots of power.

for a guitar, most amps cone with multiple 8 or 10" woofers..not subwoofers. a car subwoofer won't play as high as a speaker designed for that application.

If it was a bass though.. go for it.

the amplification is where the cost comes in, guitar loudspeakers are very inexpensive.

you're asking about sub is a sub?....a sub plays roughly 20hz-200hz, a guitar loudspeaker normally run from 70hz - 6500hz huge difference.

not sure where in Canada to get this stuff from, but parts express has everything you need, you should be able to build what you want for about half of retail. HTH

You can build your own cabinet with some knowledge of loudspeaker designs, but you need a very flat response box for it to sound proper.

its actually quite easy a guitar cabinet is usually open baffle,pretty much just a 5 sided box the length of the distance from the front of the cone to the back of the cone pretty much depicts the low cutoff frequency try this:

the impedence on a guitar or "house" speaker are usually a high number between 8 and20 ohm if i remember correctly. it depends on how many speakers are in the cabinet. most guitar amp's run at 8 ohms (i think) so whatever amp your using MUST match the impedence of the subs your running, and if running more than one sub you have to be able raise/lower impedience with bridging the speakers, just like a car, but most single voicecoil auto sub's come in 4 ohm, so one in a cabinet would be too low and cook the amp. we went through this with a 15'' in a bass amp. $400 just to replace the speaker.

Hey guys,

Thanks for all the responses.

I already have amplification in the form of a Crate BV-6212 60 watt combo amp. It sounds great alone (at lower to mid volumes) and even better with any added effects. At higher volumes, the tubes really cook and sound fantastic but I dont feel that the speakers / amp enclosure are up to snuff. Hence the reason why I was considering building a cabinet.

SIKK & MTT: So subwoofers are out and woofers are in (due to frequency response). Checking out parts express, I see a woofer section. Any recommendations on what is good in the 10" and 12" sections?
