Acoustic Research AR94s front speakers 2nd pair specifications Back to NRPavs Home
Acoustic Research AR94s tower front speakers - 2nd pair :
Acoustic Research invented many of the standard features that are used in all speakers today such as the acoustic suspension (sealed cabinet), bass reflex (air-ported type), passive bass radiator as used in this 94 model, and dome tweeters
This design was the first to use the method of 2.5 speakers – meaning that the lower bass driver is matched to take over from the mid / bass driver and radiate more energy at lower frequencies, this design is now standard for home theatre fronts
The AR 94s are tall at 80cm and so are suitable for home theatre fronts. The sound characteristic is detailed, open and transparent and at only 87 dB / 1W / 1m they are not very efficient
There is also a low impedance dip down to 2.9 ohms which makes these speakers require an amplifier with a tolerant output impedance and a decent power supply to drive them
By this, we mean that you will still get reasonable sound volume from 20 to 30W amps but for parties or a large room we are talking 80 to 150W for full range
A caveat here is that these speakers are better suited to Jazz, instrumental or classical music than for high power rock. These speakers will handle a fair range of the volume knob and get louder gradually. This has the advantage of giving you finer control of the volume suited to a given music type
The grille cloth design and speaker termination methods are also fairly unique. The wooden top screws off to reveal that the cloth is fixed as a bag
Removing the plastic speaker foot reveals also that the speaker wire has a small slot to enter so that the unit sits flat and the wire hides neatly behind the speaker : a nice feature. The grille cloth is done up like a bag with a securing cord – you simply loosen this and roll the cloth toward the top for cleaning or replacement or to inspect the drivers
The crossover design is very basic which also means that there are gentle phase transitions between the drivers and that the designers have selected the driver electrical and mechanical characteristics carefully.
