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

[Denzil]

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.

Okay, good to know that narrower width of the baffle does result in drop of DBs but does not effect "quality" of sound. So, from what I now understand, the belief that Tannoy's, especially MG 15's need wide baffles in order to breethe, etc., etc., is indeed a myth.

Yes there is. Which is why you have some designs (e.g some KEFs & B&Ws) where the bass cab is big and wide but mid- range and tweeter are mounted on a much smaller unit above. Every speaker design is a trade off of compromises. Tannoy make up for it by being dual concentric point source so what you lose on the swings you make up on the roundabout.

Okay, I understand now. Thanks so much Martin !

Extremely grateful to you and everyone here who have been so helpful with answering all my questions.

Kind regards,

Denzil

Just a quick one before I comment on some of the most recent posts here and answer the question Sailor asked me about resistors [which I'll come back to soon, I promise!]...

I bought the book below the other day on Amazon (only a few copies left), which if you don't already have, you may wish to buy....





Note the comments above (in the highlighted text) about the Lockwood's "huge low end" - something I've already mentioned and can wholly relate to...

It's a fascinating read, full of all sorts of stuff that would be right up the street of anyone interested in such material, and as such comes highly recommended!

Available here: https://www.amazon.co.uk/gp/product/...?ie=UTF8&psc=1

More later!

It's certainly a book to have. Very interesting.

I will be publishing a new post on my blog soon about my Lockwood Majors. Also included is a post about my Tannoyista crossovers for the Monitor Golds amongst other things.

Wonderful, I must try and get the book. Sadly, no international couriers due to Covid 19.

There are some interesting photos in the Lockwood Instagram account. And also in the Tannoy website, history page.

They apparently later switched (in the studios) from Tannoy to JBL because they found them to be more accurate. I'll find the link and respond with it.

"Accurate" to *what*, though?

Personally, my benchmark will always be to the MUSIC itself (and therefore in allowing it to 'breathe'), not strangling it, as a slave to achieving some notionally 'perfect' measurements. Therefore, for me, the goal ABOVE ALL ELSE, whether in the audio recording or playback chain, is to strive to create as LIFELIKE a sound as possible, ultimately using (good) ears as the arbiter.

That's what creates REALISM, so that voices sound like REAL voices, and acoustic instruments like REAL instruments.

*THAT* is true accuracy (and also ultimately the only "accuracy" in audio that matters), as opposed to often a processed, diluted, cardboard cut-out of such, when measurements/readouts on test equipment matter most. In terms of measurements, therefore, 'accuracy' should simply be used as a process to achieve the former, and never an end in itself, because in the final analysis, only the human ear can determine what sounds REAL, not a machine!

P.S I also love JBLs, but they have a rather different sound, plus their own, equally passionate, cult following!

I fully agree with everything you say. I made my cabinets with no measuring equipment and only use my ears. And I just realised, what I was talking about - Tannoy's being replaced by JBL's in the studios, that paragraph is from the same book your just bought, I was reading it online some months ago. Here's the link.

BTW, I just read the areas of interist in your profile, similar to mine. What cars have you been working on of late ? Here's a photo of my Triumph Spitfire in her dehumidified glass box.

I love the Spitfire, you not considered getting the proper chrome bumpers for it instead of those American things?
