Using a Full-Range Speaker as a Subwoofer

post #1 of 3
Thread Starter 
.....Yet another thread of questions again ,I'll try to pack all my questions into this one thread to prevent myself from creating multiple threads in the future.

-Alright, I have a pair of Compaq JBL (P/N 387767-001) laying around in the cabinet collecting dust. It states that it is 70W at the back of the woofer and it is a 3.5". So I decided to add this woofer into my current setup ,however ,I'd like to ask if this woofer is able to go as low as 40hz at least when I add it into my Home Theater Setup. Further more, will it do any harm to this woofer if I connect this to a 120W amp? Just to let you guys know, I'm not able to find the specifications sheet for this product.

Guess this is all my questions. Have fun answering them.

-Peace-

Curiosity is the key into learning more.

Are those computer speakers? I googled the p/n and that's what it's showing.

If so, you may want to take some time off of posting on the forums and look into an audio 101 guide or something. You need to get the basics down first. Off the top of my head I think Crutchfield and CNET may have some intros.

Short answer - NO a 3.5" woofer can't be used as a sub.

Well, I'm tempted to try it on my system and see how it flares well. If it's good, I'd consider permanently putting it until something goes wrong, but seriously what could go wrong? The only thing I'd not be 100% of is the sound quality, I'm sure it will sound a little distorted, won't it?
