Review on 🔊 GRS 3FR-4 Full Range 3" Speaker Driver 4 Ohm: High-Performance Audio Powerhouse by Heidi Young

Sound quality is ok but I wanted to buy these to replace the Z5500 component speakers as the rubber surround was cracked. No fitment or installation issues, but I soon realize the sound quality is nowhere near as rich as the originals. The main problem is mids and highs, where the original Z5500 delivered very good mids and highs, but this one only reproduces mids. I turned up the equalizer and still nothing. I added a dome tweeter and that fixed the problem, but it shows that the "full" area isn't really full.
