I am using Pioneer SP-BS22-LR speakers designed by Andew Jones. They were a Stereophile Magazine 2013 Editors Choice and they retail for $129.95, or less. See http://www.stereophile.com/content/stereophiles-products-2013-editors-choices
I am driving them with a Sony TA N-110 ES audio amplifier from a media room of old.
When I use headphones, which is a lot, I prefer Bose QC-15’s for their comfort and clarity.
I use a pair of Bose Computer Music Monitor Speakers. They're a wee bit expensive (like $275), but the sound is very complimentary to the radio (Flex 6500) that they are connect to. Placement of 1 on either side of the computer monitor makes the sound come right at you!
They do a 40 as well which are louder, these are damn fine, not Bose, but not Bose money either.
For on the go when I'm in the Field with the radio, either: http://www.bose.com/controller?url=/shop_online/digital_music_systems/bluetooth_speakers/soundlink_w... or http://www.bose.com/controller?url=/shop_online/digital_music_systems/bluetooth_speakers/soundlink_m...
Have tried various Bose computer speakers, as well as the Bose receiver and Bose 501s driven through a Carver amp, but nothing has sounded as good as the relatively inexpensive Klipsch ProMedia 2.1 computer speakers (about $140).
My ProMedia 2.1 installation consists of the two satellite speakers on the operating desk, separated about five feet, on either side of the Flex 6500, plus a sub-woofer on the floor. Sounds like the audio is coming straight out of the 6500. I used 1.5 inch round ferrites with about 14 turns of the speaker wire at the satellite speaker input terminals and where the speaker wires originates on the sub-woofer. 1500 watts output 80 - 10 meters, no RF in the speakers in either CW or SSB. They sound really good both on SSB and CW.
Side note: I have found that a snap-on ferrite over a speaker wire is usually inadequate unless you can loop the speaker wire back through the ferrite a few times. I have read that the RF suppression is equal to the square of the number of turns, so ten turns would provide 100x (two orders of magnitude greater) RF suppression as compared to a single pass through a snap-on ferrite. The a 1.5 inch round ferrite can support 14 - 15 turns of typical computer speaker wire.
