Soundstage and explosive dynamics?

To give the most sound advise  it would be good to know first Budget,
what you have amp type,wpc, preamp ,how big is your room,
room treatment  how far away are you sitting .  

@markus1299 Did you get rid of your 40.1s?

Nothing I have heard combines the best dynamic range with a disappearing act. That said, I would look at omnis like Ohm, German Physiks, and MBL for the disappearing part. Subwoofers will help the dynamics on these. Dynamic range can be very good on some omnis, because they have a lot of radiating surface relative to driver size. For the best dynamics, high efficiency models like horn speakers excel, but few that I have heard can disappear. One exception to that which I have heard is the Volti Audio speakers. These are horn hybrids that offer the advantages of horns in terms of dynamics, but without many of the downsides of horns, such as beaming, the "cupped hands" effect, or sound that seems anchored to the cabinets.

+1 Good observation. This is why large studio main monitors are all built into walls so they behave like an infinite baffle. Studio main monitors are exactly what "explosive dynamics" is about - they are designed to impress the hell out of a bunch of musicians and producers - a pretty tough audience to impress as these folks are in and around music daily.

My speakers have a gently curved wide front baffle and definitely disappear completely despite their massive size - incrementally more than the big box versions of my speaker that I have owned in the past and which like to be mounted in a wall.

Audio Physics disappear and so do most narrow baffle speakers but it is rare to find a design that houses 15 inch or larger woofers in a massive box (design requirements which are absolutely necessary for "explosive dynamics".) Audio physics sound great but get tuckered out and sound flat and strained at quite modest volumes. Soundstage tests some speakers to 95 db SPL (which is hardly explosve) but Soundstage readily admit that most speakers can't even handle even 95 DB SPL and many would self destruct at these modest levels (hardly high fidelity but nobody seems to mind as long as the speakers look cool)
