SKU CH-M7Z9-EZ1QP

Granite-finish rock speakers with 6.5" woofers and 1/2" tweeters deliver 80 W, 91 dB sensitivity and 40 Hz–20 kHz response for outdoor areas

  • Product typeIndoor/Outdoor Speakers
  • 5" woofer delivers deep 40Hz bass response
  • 91dB sensitivity produces loud output from modest amplifier power
  • 80W power handling supports high-volume outdoor listening
  • Coaxial tweeter design creates wide, even sound dispersion
  • Granite rock enclosure blends into garden landscapes

Outdoor Rock Speaker Pair

A pair of 6.5-inch two-way speakers housed in UV-resistant rock enclosures. Each unit combines a polypropylene cone woofer with a coaxially mounted polyamide dome tweeter. The sealed voice-coil design and silicone-encased leads protect against moisture and temperature swings. Ideal for gardens, patios and poolside zones where a natural stone look is preferred.

Suited for Landscape Background Music

Works well for installers needing discreet, weatherproof coverage across flower beds or lawns. Buyers wanting deep sub-bass extension, high-SPL party output or a dedicated subwoofer output should look at something else. The 8-ohm impedance matches most multi-zone amplifiers without extra matching transformers.

80-Watt Power Handling

The 80-watt continuous rating defines the safe amplifier ceiling for each speaker. Exceeding this level risks thermal compression or driver damage during sustained playback. Pair with an amplifier rated at or below 80 watts per channel into 8 ohms for reliable long-term performance.

Questions about this item

What amplifier power and impedance match the 80 W and 8 Ω rating of the ASM33615?

Use a stereo amplifier or receiver that delivers up to 80 watts per channel into an 8 ohm load; the speaker's 91 dB sensitivity means moderate power will drive it to loud levels.

Can the 8 Ω ASM33615 share a speaker zone with older 4 Ω or 6 Ω models?

Mixing impedances on the same amplifier channel changes the load seen by the amp; wire each pair on its own channel or use an impedance-matching selector to keep the amplifier stable.

How do I verify the 40 Hz – 20 kHz response is performing correctly after installation?

Play a frequency sweep or pink-noise test tone at moderate volume and listen for smooth output down to the low bass and up to the highest treble without buzzing or drop-outs.
