Acoustic Energy AE520 or AE509: what does the bigger tower add?
Acoustic Energy AE520 or AE509: what does the bigger tower add?
A third way. The AE509 is a two-way design with its drivers in a mid-tweeter-mid layout. The AE520 is Acoustic Energy's three-way flagship: two 125mm midrange drivers in their own sealed enclosure, three dedicated bass drivers loaded by a large rear port, and the same 25mm carbon fiber tweeter, all in carbon fiber. Acoustic Energy rates it at 30Hz (-6dB) against the AE509's 32Hz, 90dB sensitivity against 89dB, and 300 watts of power handling against 175. It weighs 30kg each against the AE509's 22kg.
What amplifier does the AE520 need?
What amplifier does the AE520 need?
Acoustic Energy rates the AE520 at 90dB sensitivity with a 6-ohm nominal impedance and 300 watts of power handling, but does not publish a recommended amplifier power. Get in touch with Mike with the amplifier you have or are considering, tube or solid state, and he will talk through the match.
How should I position the AE520?
How should I position the AE520?
The bass drivers vent through a rear-facing port, so Acoustic Energy asks for at least 6 inches of space behind rear-ported speakers, and advises keeping them away from side walls. Aim the tweeters at ear height from your seat, place the speakers and your seat in an equilateral triangle, and toe them in to suit the room. Acoustic Energy notes the speakers may benefit from a running-in period as the driver suspensions settle.
Are feet and spikes included with the AE520?
Are feet and spikes included with the AE520?
Yes. Acoustic Energy supplies solid aluminum bars that fit to the base for rigid floor coupling and stability, with M10 spikes. Floorstanding models also come with spike shoes: remove the rubber spike protectors on carpet and leave them in place on hard or wooden floors.
