2-way speaker with best bass

This was meant more in the spirit of a "best of" list, rather than as a consultation regarding a specific system.

Recently I briefly heard a diminutive Sonus Faber speaker (not sure which model) putting out prodigious quantities of bass, driven by a Simaudio I-7 integrated, though ultimately it struck me as tending more to the one-note variety.

BTW, I'm surprised to see no votes yet for the Mani-2. What else are the heavy-hitters in this field?

Merlin VSM-MXe with BAM, incredible bass quality for a two-way.

Bass extension and response depends so much on the listening room size and what's in it. Thick carpeting makes a huge difference over even thinner commercial grade carpet. Drapes and upholstered furniture helps tremendously. A first floor room on a slab (vs say a wooden floor with a basement underneath) is a more difficult environment for bass production. The same two way speaker can sound so fantastic in a smaller room with the right treatments vs even a slightly larger room without the right "bass traps" inside. Adding a 2nd powered subwoofer and bass traps are excellent suggestions.

Having said this, I would say a two way speaker with a mid-range/bass driver in the 7" to 8" diameter area vs the more popular 5" to 6" size will produce more bass ext. The Focal 807V Chorus 2-way speaker for example has a 7" mid-range/bass driver with a low frequency point of 41hz. Just a suggestion.
