Large-scale sound from a slimmer Aspen.
The Aspen FR20 is a three-way loudspeaker built around PS Audio’s planar-driver approach. This listing is for a matched stereo pair, ready to become the acoustic centerpiece of a system with suitable amplification.
One stereo pair. Dimensions and weight below are per speaker.

Planar drivers, considered as a system
10-inch planar midrange; 2.5-inch planar tweeter. These drivers work with two 8-inch woofers; two 10-inch side passive radiators to cover the music spectrum. Driver construction, crossover behavior, and enclosure loading all contribute to the final response; a listening evaluation in the intended room is more useful than any single specification.

A cabinet with a purpose
A tall cabinet places the planar drivers above a substantial bass section. Side passive radiators extend the low-frequency system without a conventional vent, while the narrower format offers another way to bring Aspen technology into a listening room.
Make it work in your system
Thoughtful setup makes the difference.
Choose stable placement
Set up the cabinets with the supplied or specified supports. Heavy speakers may require assistance during unpacking and positioning.
Explore the room
Adjust spacing, wall distance, and toe-in in small steps. Keep the listening position and left/right surroundings in mind.
Match the amplifier
Consider minimum impedance as well as sensitivity. The recommended power range is a starting point for a system conversation.

Before you choose
Common questions
Is the price for one speaker or a pair?
This listing is for a stereo pair. The dimensions and weight in the specifications describe each speaker.
Will the room change the bass response?
Yes. Placement and room acoustics affect low-frequency response. In-room bass-extension figures are not a guarantee for every room.
Keep researching.
