just got a pair of speakers in mail so i now need AMP and volume control for it.

[bossyman15]

this is my speakers...

specs of these speakers

power output: 18watts RMS at 10% THD

Frequency response 50Hz to 250 Hz

input impedence: 40HMs

oh where could i get amp and volume controller?

or i would like it to be able to plug into my PC and controll it with volume knob on my keyboard

[JustMichael]

4 ohms impedance?  I would check out used car amps.

this is where i got it...

Looks like these are only woofers ? You'll need at least also some tweeters with these, and therefore a cross-over filter.

well could you guys help me find the parts for these speakers to plug into my computer?

i never done this before and i don't know all the parts i need...

That Oscar controls link will only help you partialy since your speakers are apparntly woofers only. Those will only generate the low frequencies. (as the specs mention:
Frequency response 50Hz to 250 Hz). You will at least als need a set of tweeters or even a set of mids, depending on where you're going to go to install the speakers in your cab.

The normal audio frequency range is about from 20 Hz to 20.000 Hz. There are speakers that can handle the entire frequency range. These are usualy dual-cone speakers. Sometimes you also have speakers with a seperate tweeter "built in". (often car speakers), these can also handle the full audio range.


however, if you're gonna send a frequency of about 10.000 Hz to your woofers, they're not going to like that. Even more so the other way around, tweeters cannot handle low frequencies. That is why every good speaker has a cross-over filter. Those filters seperate the frequency ranges for each speaker it drives, so that the right speaker gets the right frequency range.

It all depends on your goals: if you want a simple solution to use sound in your cab and don't need Hi-Fi like sound, I'd suggest to get a pair of full-range speakers instead of these woofers. If you do want HiFi-like sound, you will need at least a set of tweeters and 2-way cross-over filters. If you are planning on mounting the tweeters and woofers a long distance from eachother, you'll be needing a set of mid's and 3-way cross-overs.

Take a look at my audio set-up: http://forum.arcadecontrols.com/index.php?topic=42798.0

urrrm i never done any work with speakers before so i don't really understand the tweeters and mids stuff. 

if you could point me to right parts that would be very helpful

(after all i would be willing to learn something new!)

Check this out:

It covers everything!

If you have a low frequency driver you can make a "2 channel" speaker just by adding a high frequency driver. Each driver will need a crossover so the high dosen't get low frequencies and the low dosen't get high frequencies. I think the high frequency driver uses a capacitor and the low uses a coil.

I should also note that if you don't want to mess with figuring out speakers and crossovers just buy (2) "full range drivers".

Full range drivers cover the whole sound spectrum (low, mid, and high) in a single driver.

They can be found in TV's too.
