Review on 🔊 Powerful 8 Inch Car Subwoofer Speaker - 350 Watt High-Powered Audio System with 1.5 Inch Kapton Voice Coil and 89.2 dB Sound by Mark Harrison

I have used them before and bought them from another seller. I bought two from Revain and one came with a roll and told me. Let's see what happens because I've never had speakers that do that. I installed them in Goldwood Studio Monitors Acoustic Audio, Black (PA-380X, great cabinet to upgrade)... to upgrade the cabinets and forgot that one of the speakers was wrapped and one of them had a very distorted sound. and drove me crazy I changed crossovers. twice. Speaker cable from the amplifier. from side to side on the amplifier. So this is a friction coil. So I had one speaker left over from another project, I installed it and fixed it. No more distortion. It's great when you get a good one. Unfortunately I get another one that matches the one I changed. I WILL CHECK AND NOT INSTALL THE SPEAKER COIL. Something else. Why do they have a plastic ring on the front? No way, dammit, I couldn't take it off. suitable for the speaker I have set.
