Alpine's S-Series speakers feature rugged looks and tough, ultra-rigid cones. The 2-way SPS-570A 5"x7"/6"x8 speaker brings home full bass and accurate midrange with its aluminum-coated polypropylene woofer. The durable rubber surround resists deterioration from heat and humdity, adding years to the life of the speaker.

A titanium-coated PEI dome tweeter produces sharp details across a wide dispersion pattern for excellent imaging. You can swivel the titanium-coated PEI balanced dome tweeter up to 15° to fine tune high-frequency focus. Grilles are not included — factory grilles are appropriate for most installations.

Key Features:

• aluminum-coated polypropylene woofer
• rubber surround
• swiveling titanium-coated PEI balanced dome tweeter
• frequency response 35-30,000 Hz
• recommended power range 2-40 watts RMS
• peak power 200 watts
• sensitivity 92 dB
• top-mount depth 2-7/16"
• 1-year warranty
