Tannoy has been around since the dawn of audio. In the UK, people refer to speakers in general as tannoys. Tannoy is popular in Europe, Japan and Canada amongst audiophiles. The older dual concentrics are very desirable and command a price of many thousands of dollars. The newer high end ones are just too expensive for most budgets.
The good news is that there are Tannoy speakers to fit just about every budget.
Their flagship driver is the dual concentric (excellent soundstage, pinpoint imaging), wherein all frequencies are driven by a single driver (composed of a tweet/woofer combination). Kef is another UK manufacturer that uses a similar approach (the Uni-Q). The sound from UK speakers is much more relaxed than US speakers (which tend to "thump", can be shrilly and sound forward IMHO). Maybe the difference in these two types of speakers is a reflection of each nations temperament? This might explain why Tannoy is less well know in the US as it is elsewhere? I wonder.
If speakers were a family, Tannoy would be the cuban cigar smoking, sophisticated gentleman: a calm, wise and responsible patriarch. JBL would be the bratty young adult: loud, assertive and excitable. I know that I'm describing these two speakers with broad strokes but I'm doing it only for demonstration. Depending on your taste, you might choose one or the other.
I have owned many brands/types of speakers and have settled with Tannoy Dual Concentrics. They provide all I want from a speaker and are not fatigue inducing. Yes, they can rock and roll but they can also play Bach and John Coltrane with accuracy second to none. The most realistic piano sounds I've ever heard from a speaker came from Tannoy Dual Concentrics.
The speakers you are looking at purchasing are 2 way, separate tweeter and woofer, bi-amp able, rear ported, mass market speakers. I'm not familiar with this particular speaker but judging from the look of its construction/design they should perform well in a small room (near field monitoring).
If you are unfamiliar with the UK "sound", these might be a relatively inexpensive way to get an introduction. Then again, I am only speculating on the sound of this speaker as I myself have never heard this design.
