Looking for a narrow baffle small footprint speaker

I immediately think of the KEF LS60.  Hard to beat in my opinion for the size.  Simple.

what’s your amplification?  what speakers are you replacing?

Sonner speakers. These speakers win awards as one of the best rooms At audio shows. IN CRAPPY HOTEL ROOMS!  Think of how good they will sound at home regardless of using tube or solid state gear. Make sure to buy the stands for the bookshelf speakers because they do help the sound quite a bit. I think it’s like $14k-$16k for their top speaker and stand. I listened to these speakers at Axpona ‘24. There was a classical conductor in the room. He listened to a few tracks he picked off the iPad app. He said after he finished listening that the sound is as close to real as you can get. If I did not already purchase my Revel Studio 2 speakers the Sonner speakers would be my choice. 

The Speakers shown from the Brand in the Link have models that should meet the criteria for the Cabinet Dimension being requested.

The models are when looking at user reports suggesting these designs are abletp punch way above their asking price.

I have heard the Celeste in a very well known System where Quad ESL's are resident, and the story that is unfolding is that the TOTR Quad models are being used much less now the Celeste has been discovered.

The Celeste were purchased for a Low Watt Output Amp' used in a Second System. They are now edging their way to permanent use in the main system.
