Controls/Adjustments
NOTE: As with most speakers, the 4309 has transducers whose suspensions will take several weeks to "break in" and achieve optimum
performance. During this period, the balance between woofer, and UHF trim level may change, so we recommend that you adjust the UHF
controls accordingly.
