ZIMO Speaker - 20mm Round

• 20mm Round
• 80mm Wire Leads
• 8 ohm
• 0.5 Watts

All ZIMO decoders are able to use 8 ohm speakers, most can use 4 ohm speakers or (2) 8 ohm speakers connected in parallel.

Miniature types such as MX648, MX649 and MX658 should only use 8 ohm speakers.

Small scale sound decoders (MX645, MX644, MX646, MX648, ...) work with 5 V power supply for the sound amplifier (miniature types create 1W audio power, otherwise 3W audio power).  Typical N- and 00/H0 speakers which are 0.5 W to 2 W.

Large scale sound decoders (MX695, '696,' 697, '699) work with 10 V power supply (and 10 W audio power into 4 ohms).  Therefore ZIMO large scale decoders (10 V) should ONLY use Speakers > 3W.

ZIMO offers special types of miniature rectangular speakers with special resonance bodies and are produced in cooperation with ZIMO business partners.  They offer excellent sound quality considering the size.  These special models are not commercially available elsewhere.

The other listed speakers (Round Speakers and VISATON speakers) are standard types.
