Hi Everyone! I haven't been here for quite a while, but it's nice to know you're here to ask when i need some advice!
I'm in charge of rebuilding a foldback speaker wedge. It is about 20 litres, sealed (can make vented if necessary). It has a hole for a 12in woofer and a 10.5in by 4in piezo tweeter horn. I want to keep it as cheap as possible. There's a possibility of making it active by adding a built-in amp. this will probably be 70W or less. The wedge is mostly used for vocals.
The horn appears to be okay (the woofer wasn't too healthy, and overdriving it with feedback from a Crown amp didn't help. The amp survived
). However, it's a cheap Realistic, and i have no idea of the sensitivity, power rating, or frequency response. By ear, it sounds like about 2kHz + . It has a 4.7uF cap in series with it. I don't know if that tells you anything. I don't mind replacing the horn (the driver isn't detachable) if it means a good match between tweeter and woofer.
I have had a small look at some peerless, diachi, and other woofers, but they all get rather large humps at about 100Hz in the small sealed box. Not that i'm too worried about fidelity. Any ideas? I don't have any software for simulating vented boxes....
