How do you clean white resin chairs that have turned powery on the outside?
first of all a woofer or coned-speaker cannot produce frequencies above a few thousand hertz, True treble comes from tweeters or horns producing frequencies arounf 1000hz up to 20000 hz. While speaker performance is reflected in the materials, engineering and connection, some improvment can be obtained from Equalization, boosting 40hz-250hz. Also make sure speakers are polarized correctly, and the proper impedence is adhered to for the amp specs.
Do a pressure blow-off at day's end to avoid corrosion and keep on riding!
