Do you have the data for the 4.5s?Also wanted to share additional specs on these. They don’t look bad in paper. The magnet is small, however is neodymium vs ferrite…. So the strength of the magnet is greater
Any identification of alpine crossover frequency?
Knowing the sensitivity is a good point for looking at speaker replacement impact. If the 3.5s are in fact 4 ohms and 86 db sensitivity, it makes sense 2 ohm 90db+ replacements are screaming.
Anyone run pink noise on a Audio Spectrum Analyzer on the alpine system stock and flat? I'd do it if the truck was here (still on order).
Quadratec's "super tweeters" (cheap power bass tweeters on a adapter) come with a spectrum analysis, assumed from a non alpine JL. They show pretty intense roll off in the highs with significant improvement from a simple bass blocker'd tweeter replacement: Note, they increase the bass by 2 clicks on the stock EQ between measurements.
