Speaker recommendations 10 to 30k and no beryllium

There are 3 KEF Blade 2 on sale on Audiogon at the moment from 13K to 18K. I have no space for them today but the bad voice in my head says to buy 1 of these listings and keep it in storage. The good voice in my head tells me to to have patience and buy later when I have the space.

Give Dali Epicon 8 a listen. 

So grills always on then... unless you block or teach the children otherwise 

That rules out my suggestion of PMC MB2SE 

MBL 120 might work great for you. They have a fantastic soundstage.

DeVore Orangutang and Vivid has been mentioned already and I agree that they are great. Borresen 01 might work if you can accept standmounts.

Two names I haven't seen that I think are worth checking out are Aequo Stilla and Boenicke W11. Might be harder to find.

The only thing I would say about Raidho is you need to give them space to breathe and that tweeter is very delicate. It won’t make your kids sick but it can be ruined easily by them and Raidho does not offer grills.
That being said, most amazing soundstage I have ever heard when they are set up perfectly. $18K for D3 v2 is a fine price. You may want to reach out to Raidho and see if an upgrade is available and how much it would be.

otherwise, Blades! Vivid Giyas! Joseph Audio Perspectives! This is choice!
