I do not have tweeters, but when I go back to that electronics shop to get some other caps, i will also check out the rest of their speakers, most of them were low quality speakers, that are meant for just tones, but then they had a few subs, 2 for $10, so i got 2. they are around 8", end to end, so a 4" radius, they had a good bass response with my ipod powering them, so I can't wait to here them hooked to an amp. Luckily they are a common size, so a re-foaming kit will be easy to find down the road.
