Amplifier Requitzmmis .-

Suitable for use with amplifiers capablc of providing
between $0 and 300 W into a 4 ohm resisLiVe load

Nominal Impedance:

4 ohm resistive from 20 Hz r 20 kHz

Enclosure Type:

Twin Coupled Caviry

in.

45.9 x13 x17.6

Notes:

1. Measured at 2 m on refuence axis.

2. Maximum spl, measured ar 2 m, on programme peaks under rvpical listening conditions.
3. Measured in 1 m on reference axis for pink noise input «2.23 v rms, band limited 50 Hz - 20

kHz (anechoie conditions)

4. Amplifier requirement figures are intended only as a guide. As a general rule buy Lhe higgesr
amplifier you can afield widiin the specified range and use ii with care. It is easier to damage
the loudspeaker by using a small amplifier driven iniu distortion by too much volume wish bass
and treble boost, than by using a larger amplifier which has power in reserve. If in doubt, ask

ynur dealer.
