Although it's true that the Dayton Audio Designer Series DSA175-8 is a nice
looking and well thought-out 6-1/2" woofer, its ability to handle full rated
power down to 39 Hz without exceeding Xmax is very impressive!
Key Features
Cosmetic frame with low profile lip, designed for front mounting—no
countersinking required!
Low distortion motor system with copper shorting ring
Black anodized aluminum cone, half roll rubber surround for durability and
accurate reproduction
Smooth frequency response and linear roll-off simplify filter design
Vented pole piece for minimized power compression and maximized
reliability
Retains the same "family look" as the popular Dayton Audio DVC Series
subwoofers and passive radiators
Generous Xmax capability encourages use of moderate bass boost to tailor
the response
The Designer Series by Dayton Audio was developed specifically with the
speaker designer in mind. It is an affordable, attractive line of drivers that
puts performance first. Careful engineering ensures that each speaker in the
series is capable of handling full rated power at the lowest possible
frequencies — without exceeding Xmax.
These speakers combine useful performance parameters with elegant style.
Carefully optimized to provide superb audio reproduction when incorporated into
a wide variety of enclosures and alignments, the Designer Series transducers put
a beautiful face on audiophile excellence.
