Like some Kef, Klipsch or Jbl tower speakers.

The A180 has a way bigger baffle - more directivity in the mids and probably more directivity vertical depending on filter frequency.
There is no directivity at bass frequencies <150Hz at all - as the measurements show.
Directivity for both is very low - I would not overestimate the influence of 1dB difference there. Reflections are still very strong for both.
Ok frequency range of bass mid and so on isn't that exact. The frequency range from about the Schroeder Frequency to about 800Hz is the range I am referring to.
For sound power di 1.5dB isn't that small. E.g. a big speaker like the JBL M2 achieves about 2.5 - 3dB difference in sound power di in that range. And that is the difference of a 5" bookshelf and a big monitor with a 15" driver...
I think the term "endgame" is very subjective. The combo of 120II+750+MA1 will be very hard to beat for the money overall and sufficient for a lot of use cases.
Yes of cause it is very subjective but a small nearfield monitor with a subwoofer can't compete in the mid to far field with any good speaker which is made for the higher listening distance (+ subwoofer if needed).

The main problem with speakers with such a big difference in the di in the lower and higher frequencies is that they get much less better with better room acoustics compared to a more constant di speaker. IMHO you won't get envelopment and exactness at the same time no matter how much you improve the room acoustics.

It is also not possible to get rid of the floor bounce hole in the frequency range of about 200 to 300Hz and that is one other important problem with small bookshelf speakers. The prediction of the in room response which is used to calculate the predicted preference score is a simple estimation and doesn't take such issues into account. Even an inexpensive tower speaker with multiple woofers can solve most of these issues and you can definitely hear this difference between such a speaker and a small bookshelf speaker.

你好,

我也会考虑塔式扬声器。塔有许多潜在的好处。多个低音扬声器在较低频率下提供更高的方向性,这将增加收听位置的直接声音量。这大大提高了2m时的音质。

在书架式扬声器和2米的收听距离下,您还会得到230Hz左右的典型下降,因为地板反弹在此收听距离下是异相的。这也可以通过塔式扬声器来避免,其中一个或多个低音扬声器可以靠近地板放置。

在买东西之前,我会听一些不同的演讲者。例如,Kef R3或Neumann KH150之类的扬声器并不是每个人的正确选择,因为它们在较高频率时发出很多声音,在较低频率时发出的声音不多。与Ascend Acoustics Sierra Titan等扬声器相比,它们听起来非常不同,后者提供了更恒定的指向性。
So what do you recommend for active and passive tower speakers?

It highly depends on the listening distance, room acoustics and your preference for more or less room interaction and many other aspects. There are many brand which are worth to listen to. I would also give brands which are here considered to be bad a try like B&W and others. There is a huge difference between an electrostatic dipol speaker and a big horn system or a more average tower speaker all can sound very good.
