Speakers / Passive Speakers

Passive Speakers.

Passive 8 ohm PA speakers from 100W to 150W with 6in, 8in and 10in woofers, 94-96 dB sensitivity and up to 122 dB maximum SPL for live sound and events.

About passive speakers

Passive speakers are for foreground sound: a stage, an event, a hall where the audio is the point rather than the background. They run at a fixed 8 ohm impedance from a dedicated amplifier channel, which is what allows far higher output per cabinet than a distributed 100V line speaker can manage.

The range covers 6, 8 and 10 inch cabinets at 100W to 150W rated power, with sensitivity from 94 dB to 96 dB and maximum SPL up to 122 dB. Crossover slope is -12 dB/octave across the range.

These are the cabinets to pair with subwoofers when the system also has to carry music with real low end.

How to choose passive speakers

01

Sensitivity matters more than rated power

The difference between the 94 dB PS-06 and the 96 dB PS-08 is worth more in practice than the difference in wattage — 3 dB of sensitivity is equivalent to doubling amplifier power. Read sensitivity and maximum SPL together to understand how loud a cabinet will actually go.

02

Size the woofer to the room

The 6 inch PS-06 suits small halls, meeting spaces and fill duties. The 8 inch PS-08 handles a medium hall or a modest live setup. The 10 inch PN-10 reaches lower — 62 Hz against 70 Hz — and has a defined 70 by 55 degree dispersion pattern, which helps in rooms where you need to aim coverage at the audience and away from reflective surfaces.

03

Check your amplifier can drive 8 ohms

These are low-impedance cabinets, so they connect to the amplifier's 4-16 ohm output, not the 70V/100V taps. One amplifier channel drives one cabinet — this is not a distributed system, and you cannot chain a dozen of them on one line.

Common questions

01What is the difference between passive speakers and 100V line speakers?

A passive speaker is a fixed 8 ohm load that takes a whole amplifier channel to itself and delivers high output. A 100V line speaker has a transformer with selectable taps and shares one amplifier with many other speakers. Passive is for foreground sound in one place; 100V line is for even coverage across a building.

02How much amplifier power do I need for these?

Match the amplifier's 8 ohm rating to the cabinet's rated power, with some headroom. A 150W cabinet is well served by an amplifier delivering 150W to 200W into 8 ohms per channel.

03Do I need a subwoofer with passive speakers?

For speech and light background music, no — the PS-08 reaches 65 Hz and the PN-10 reaches 62 Hz. For events, DJ use or anything with programmed music, adding a subwoofer takes the low-frequency load off the main cabinets and lets them play louder and cleaner.
