Product details

Dayton Audio DS90-8 3″ Designer Series Extended-Range Speaker

 

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.

 

  • Suggested enclosures:

Sealed cabinet: Type: Acoustic suspension (alpha 3.5), Qtc 0.69; Size (internal) including volume displaced by driver: 0.03 ft³; Internal cabinet dimensions (golden ratio): 6-1/4″H x 3-7/8″W x 2-3/8″D. Typical results: 3 dB down-point (f3): 158 Hz; Low frequency limit at rated power without exceeding conventional Xmax (i.e. (voice coil length – gap height) / 2)): 90 Hz.

 

Vented cabinet: Type: Bass reflex; Size (internal) including volume displaced by driver and port: 0.12 ft³; Internal cabinet dimensions (golden ratio): 7-3/4″H x 4-3/4″W x 3″D; Port dimensions (with flared exit): 1″ dia. x 6″L. Typical results: 3 dB down-point (f3): 73 Hz; Tuning frequency (fb): 69 Hz; Low frequency limit at rated power without exceeding conventional Xmax (i.e. (voice coil length – gap height) / 2)): 70 Hz.

 

Frequency response (FRD) and Impedance (ZMA) data files available to assist in crossover and enclosure modeling.
