Speaker recommendations 10 to 30k and no beryllium

A lot of good suggestions.  Not knowing your musical and listening preferences or your associated equipment, I'd suggest Vandersteens as a general suggestion (Quattros or perhaps even a used Model 5A), and one no one has mentioned are Nola speakers--their Metro Gold References should work well in your room, especially good with tube amplification.  But they have ribbon tweeters, not sure if you want the kids poking their fingers around those.

Go to your dealer and get a pair of Maggies. Take them home and listen to them (your dealer will set them up for you.)

If your gear is not top notch, you will probably not like what you hear on the Maggies. This is the sound of the GEAR, not the speakers.

If you don’t care for them, it really does not matter what speaker you buy. It will be a box or electrostat and distort and cause listening fatigue.
You may also find that most all "better" speakers today are about 6' high.  Wonder where they got that idea???

Remember that your room is the most important part of your system, so work with your dealer to make sure it is at optimum listening quality.

Most of all, enjoy the MUSIC. That is what this is all about.

Cheers!

Definitely check out the Revel Ultima Salon-2.

They do everything perfectly.

I've been an audiophile for 50 years.

I started a what's the best speaker for around $10k used thread and got as many answers as there are speakers too. In this price range I should have worded my question " what $10 k speakers go with xxx components. good luck.

Purchased a pair of Legacy Whisper last spring and love them.

I listened to both the Whisper and the Aeris, and liked the Whisper better for 2 channel audio. The Aeris probably had the edge for Theater (which my setup is dual purpose), but 2 channel is my priority.
