Try under "ELECTRONICS" rather than "ELECTRICAL WIRING". The hifi guys are over there.

Do you mean you're just going to use the tips as speaker cabinets or are you intending to put these on your exhaust pipes?

lol I’m gonna use the tips as speaker cabinets

If you are just looking at making noise, you could probably do that. If you are looking at some quality sound out of your computer you are better off getting something specifically designed for your computer, something like Altec Lansing ACS33 or similar.

Depends on what you're after. It'll look interesting, if you're into that kind of stuff. The sound will be somewhere between mediocre and awful, but if you're mainly after the looks and the novelty, that may not matter.

So any tips on how to make it sound good?

Use a real speaker cabinet. There's a reason they don't look like exhaust pipes. :)

But what the heck, why not go ahead and try the pipes? It won't be accurate music reproduction, but you might decide you like it anyway.

The idea reminds me a little of the tubular extension speaker a friend of mine bought for his transistor radio, back in the 1960s. It was a tube about 2-1/2 or 3" in diameter and maybe 10-12" long, probably just a gussied-up mailing tube, with grills on the ends and a cheap 2" or so speaker fastened in the middle. As far as I can recall, it looked exactly like this one.

It had all kinds of upper-bass frequency response peaks, so it made the radio sound kind of tubby. It wasn't anything like what you'd call high fidelity, but he liked it, and what else matters? To each his own.

Kinda late to the party here but the main thing is whether the cabinet is sealed or ported, and the size. I would go with the same type of enclosure the original speaker had, and as close to the same internal volume as possible. The cabinet will have the most impact in the bass region, and if you get it wrong, you will lose a lot of performance.
