One of the main design goals at Dayton Audio is to create loudspeakers that
can achieve high levels of performance at reasonable prices. The Dayton Audio
DC130B-4 5-1/4" woofer is a great example of this approach. It features a
non-pressed treated paper cone, rubber half-roll surround, ASV voice coil,
vented pole piece, coated cloth dust cap, and excellent low frequency
response.
