Speakerless speaker for PC
 

Does anybody know where I can get a PC speaker that isn't a speaker? I want to hook up two big mono speakers to it. It'll need to plug into a wall, I'm sure, to produce big sound. I know it sounds kinda...different...but I tried plugging in one of these custom speakers to an old PC speaker with a single mono output jack (for the other speaker in the pair) and it worked really well. I just want to be able to hook both speakers up, and since they can handle 100 watts, I don't want an extra low-power speaker that's just going to distort the sound and probably get fried. Thanks.
