I've been reading about guitar frequencies and speaker drivers because I'm considering getting a powered speaker cabinet. Here is some interesting frequency data that is new to me. 1. The fundamental frequencies in the playable range of the typical, in-tune electric guitar covers the range from about 80 Hz to about 1200 Hz. (That is much lower than I would have guessed.) 2. The frequency range relevant to electric guitars, which is similar to a regular woofer type driver, is approximately 75 Hz to 5 kHz. That is the more relevent data. Most PA speakers have two drivers and the crossover is around 2 kHz to 2.5 kHz. This implies that the tweeters are better than woofers at 2.5 kHz and up. By "better" I mean more accurate or precise or both. This may or may not be better for guitar tone. I suspect it isn’t better or guitar amps would include tweeters. Tweeters are pretty cheap but then a crossover is required too. Anyway, if tweeters in guitar amps were better I suspect they would have them, at least the more expensive ones would. But a lot of guitarists play through PA's or their own PA speakers which have tweeters and they like them. I suspect good PA speakers may sound more like reference speakers. Yes, I'm thinking out loud. Please feel free to join in.
