![[GRADE B] DAYTON AUDIO MKSX4 Low Profil Subwoofer Speaker 160W Ø20cm](https://www.audiophonics.fr/72897-thumb_default/dayton-audio-mksx4-low-profil-subwoofer-speaker-160w-o20cm.jpg)
DAYTON AUDIO DC300-8 Woofer 80W 8 Ohm 90dB 25Hz-2500Hz
The Dayton Audio DC300-8 is a 30.48 cm (12") woofer designed to replace a faulty driver in a large-format speaker. Compatible with two- or three-way configurations, in sealed or bass-reflex enclosures, it restores the operation of an existing system without altering its overall architecture.
Its rubber surround withstands repeated stress and extends the driver's service life. This design is suitable both for routine repairs and for bringing older speakers back into service, particularly when restoring vintage models.
