Do the OPAL1 speakers need an amplifier?

Yes. They are passive speakers rated at 8 ohms and 200 watts RMS, so you need a receiver or integrated amp to drive them.

How much power should I pair with them?

Aim for at least 50 to 100 watts per channel. At 78.5 dB sensitivity they need real power to reach loud levels cleanly.

No. The pair is wired only, with no built-in electronics. Any streaming or Bluetooth comes from your amp or source.

Dayton rates them to 32Hz at -3dB in half-space, helped by dual passive radiators instead of a port.

A pair of gloss black speakers with magnetic grilles. Speaker wire and stands are not included.
