Which Tannoys, folks?

Getting it back to the speakers

I think the point is here is that to get some kind of realistic sound level you do need to move a lot of air, or at least be capable of doing it when called for!

The thing with the Tannoys is the coaxial tweeter that effectively makes all the sound radiate from one place, that single driver. Generally most people will think of the 15" unit as optimum simply because it can move the most air.

Personally I'd go for a Tannoy that one of the members on here owns (can't think of his name right now) that uses a smaller 10" coaxial driver & a pair of 12" drivers for filling in the bass. At bass frequencies sound is omnidirectional, so you'd never notice it wasn't eminating from a single driver anyway. I'm also sure that a 10" driver would do a better job in the midrange (less distortion) up to the crossover frequency of the tweeter than a 15" would, simply because it'd act as more of a piston.

Give the bass over to those 12" drivers at less than 150Hz say & I'm sure it'd be something to behold

Tannoy appear to be going back to a similar setup with their modern speakers, a smaller coaxial but paired with a 15 or maybe even an 18" bass unit in there largest speakers.

It makes total sense

Hi Mark

I think that big drivers, particularly when horn loaded, seem to be able to move the air in the room effortlessly. It's a bit like driving a 4.2 litre Jag on the motorway at 70mph. It's working well within its capabilities and it shows. A small driver trying to do the same thing is going like stink and that extra effort is reflected in the quality of the output which by comparison sounds strained.

Kind regards
