The biggest debate in the history of humankind -Tannoy crossovers original vs new.

[cooky]

No it wouldn't matter. But when Tannoy designed the original cabs watts were very expensive. As Charlie mentioned to get that 3dB back you need double the power. No big deal now but back in the days before transistors, and for a while after transistor amps appeared, it was.

Here's a thing, and I may be missing something but I doubt it, open up a 12" Lancaster then compare its crossover with a 12" Chatsworth, the crossovers are exactly the same, look at an Arden and Berkeley again same crossover, look at a Mansfield vs an Amesbury etc etc .... so where does that leave the Baffle step compensation?

PS, for the OP's question I'm of the opinion Tannoy engineers knew/know what they are doing. To these ears at least the biggest improvement is in hard wiring-all other things being within spec, speaking of which it isn't just components that age, the drivers do too and the bespoke crossovers that include the driver in the design will always be better than some off the shelf clone-sh one.

In the spirit of sharing information, and archiving development of Lockwood cabs, some internal shots here;

That's a lovely website Josie I've just read your last review of the pre and I really like the way you go into the detail of the components and the build, very few reviews do that and I really prefer to know these facts before I buy. The photography is very high quality as well. 10/10

Apologies, folks, but I'll get back to the main thrust of this thread soon, and in that respect reply to some of the posts I've missed. However, until then, for Denzil and others who may be interested, here are some rear and internal views of my 15" MGs in Lockwood Major cabs with bespoke crossovers:

Hi Marco,

I have a question re Lockwood cabinets to which I've found no answer anywhere on the planet.

The felt on the aperiodic shelf, can you please describe it. It it dense ? Is it very porous and soft ? Is it like the felt used to line car subwoofers ? How thick is it. And is the felt in your Lockwoods the original felt ?

Regards,

Denzil

The felt looks very similar to wool carpet underlay.

Thanks Matt !

So I guess it would be something like this ?

That looks like the stuff, but I can't see if it has any wool content. Wool is supposed to be better than polyester for speaker stuffing.
