Help! need informed opinion

If this was me, I would only buy the Revels with a reasonable return policy as you may find they drift a little bright.  

I find Dynaudio pretty neutral and the Special 40 is a very good speaker.  That would be my choice among your initial suggestions.  I have not heard the Aerials.  

An interesting option would be the Vienna Acoustics Haydn Grand Symphony Edition.  They are a well designed speaker with a front port and placement is pretty easy to manage.  They are neutral and I think are aesthetically pretty simple yet appealing.  I believe these list for $3500. It has a frequency response to 40hz though I am sure it rolls off a bit before that.   

You might also look at Spendor.  The Classic 3/1 is at the top of your budget ($4K) but is an incredibly good sounding speaker and is very natural.  Spendor doesn't have a hint of brightness and frequency response is stated at 40hz though I am sure it rolls off a bit before that.  

With some patience and you may find a used pair of Joseph Audio Pulsars on your budget. That would an A+ option as they are really pretty awesome for the money. I have attempted a similar speaker and the Joseph crossover is what makes that speaker great. Mine are good. The Pulsar is great. This has very deep bass for a stand mount and would be a first choice.

Watkins Gen 4. Very impressive sound for a monitor bookshelf speakers. Don’t let the price fool you. They won the golden ear award 2 yrs straight. Don’t know about this year. 30 day$$ back. Good people too. Fwiw Watkins designed and holds patent on Infinity dual drive woofer among other patents.
Also they go down to 42 hz. I was surprised by the bass response

If you can use a floor stander contact Dennis at Philharmonic and ask about the Philharmonic BMR Floor Stand model or the Philharmonic BMR Bookshelf. The floor stander is under $4k the Bookshelf about $2k.

Man I was thinking,with the room you described I might look at the Wharfedale Linton 85th.Anniversary 3 way with dedicated stands..They are voiced very organic & rich & IMO would thrive in that type of room.Oh you'll save a ton of $ as well...

I’ve currently have Dyn special 40’s and have had a few pairs of Revels - f208 and Concerta2 M16’s. The revels are great because they are very balanced and do not really color the sound coming to them. They just weren’t for me.

I am so happy with my Dyns and their house sound. It’s just perfect to my ears, no matter what I have feeeding them.
