Any experience with Tannoy loudspeakers?

I've heard many Tannoy speakers and generally they tend to have a family sound with generous midbass and a smooth, non-emphasised top end. This can sound slightly shut in compared to some rivals, but never thin.

I love this full (old fashioned?) sound on all the models I've heard (with the exception of one of the large Dimension models which took this fullness a bit too far in my opinion).

The M1, R3, and the HPD 385s all have that classic Tannoy sound. Even the floor standing MX3s sounded like Tannoys despite their elevated treble response.

I have read of complaints regarding sibilance on some vintage models and others seem keen on 'improving' the enclosures on the older models but I'd steer well clear of such ideas.

Its only the fully horn loaded Westminster, so beloved of the late Harvey 'Gizmo' Rosenburg that have elaborate cabinetwork. The rest seem very matter of fact, but this was quite intentional.

@ dan, you're a braver man than me and no doubt more knowledgeable in these matters.

Still, I hope you don't mind a few suggestions, that might be worth bearing in mind. The original Tannoy's all used chipboard as cabinet material, and to a large extent it works really well. With MDF I believe it is possible to get good results, but more care may be needed to keep those nasty resonances away from the midrange. 

Secondly, as is being appreciated more and more, the driver/cabinet coupling is all important, so it's well worth experimenting with the tightness of the driver bolts. I strongly believe that no more than finger tightness is required (for any large heavy Tannoy DC drivers). 

So it might be worth playing around with that too. Best of luck.
