As a dealer I have really struggled to find modern speakers that are truly musical.
The move away from birch-ply to MDF has been cost-led and a very retrograde step as this material, due to its uniformity, stores energy at a certain frequency often leading to a lumpiness somewhere in the mid bass. Actually, chipboard which is more `random` in form sounds more open and natural ! E.g. Mission 770 mk2.
To compensate for this overdamped thickness, stark, metal-dome tweeters are often used which can never match the tone of their bass-mid drivers unless they too are of a similar material. And yet, when `brave new world` matching materials are used for tweeter and bass/mid, they often fail to deliver because although detailed, the result is just not musical. E.g. most ceramic drivers.
I look out for designs which use birch-ply or go for differing thicknesses in their cabinetry to disperse energy more randomly.
Silk-dome tweeters and paper or hemp mid/bass drivers are often more natural.
Ribbon tweeters are extremely detailed but their coherence with a conventional bass driver often leads to a total mismatch.
It`s not just about detail and using the latest technology, some artistic licence and emotional intelligence is needed to make a design coherent and involving.
