Like I have said before age has it's priviliages! :-) and they were good drivers but i many ways I am begining to believe that the ga Jme has moved on.ust like the game for the big block (350cc and more) V8s has moved on with the new advent of modern 2.0 liter "microprocessor controlled turbochagered and fuel injected" engines producing all the power/torque with half the weight.
Like it or not the HF unit looks like it is a "wave guide". The only disagreemment we seem to have is if this wave guide is moving (a woofer cone). I do not understand how you can say that the woofer in a tannoy dual concentric will not affect the HF emanting from it's center.
I am not comparing a dual concentric to a traditional multi way speaker. I too find most of these missing that "special something". Fullranges despite their shortcomig i managing the entire musical spectrum (some are also strangely coloured in their delivery) are more coherent. My experiences with managing a fullrange (Jordan JX92) using a "super tweeter" like the OW4 and a woofer like a pair of 8" (Focal 8K516J in this case) have not been very successful. Although my XO is around 100 and 5k the coherence still gets lost. So the search goes on. Other options (dipoles, planar-dynamic combos, and more) will also have to be further researched. I have tried one planar dynamic combo that was nice (but coloured) using a pair of 12" (isobarik) mated to a Maggie SMGa.
Now I fear we are seriously OT. Thanks to my initial comment. So before the rest of the forum starts leaving we should take this discussion to PM.
Disclaimer: I have not heard or used the smaller 6.5 and 8" DC Tannoys other than some rudimentery listening at various Audio shows. |
Tannoy still rules as drivers. Don't judge Tannoy by listening to mass market residential speakers. Comapre neck to neck the high end loudspeakers with Tannoy Prestige / Dimension Series you will know that Tannoy is still up there and far ahead from most.
There is only one loudspeaker in Tannoy range today which is horn loaded and that is their Reference Westminster Royal HE, which also is a 530 litres compound horn cabinet loaded with 15" Dual Concentric Alnico Magnet driver. The low / bass notes are horn loaded below 200 Hz, above 200 Hz it is a front firing point source.
The so called modern fuel injected turbo / supercharged 2.0L type loudspeaker will sound like "Meow" in front of this monster which is actually a 426 cu.in. Hemi V8. Remember no replacement for displacement.
The wave guide is not moving. Its stationary and sits in front of the tweeter inside the woofers voice coil and the throw of HF is controlled by this waveguide not by woofer cone.
There are no issues of LF disturbing the HF. If it ever was aproblem which is not small by any standards Tannoy Engineers would have been the first one to know, the Dual Concentric driver would have been the disaster and Tannoy cannot afford to carry a faulty design for more than 70 years. Moreover it could not be winning hearts of Audiophiles across the world and could never make it to mastering studios with that flaw if it ever was existant.
Regarding supertweeter I have listened for a long time to Tannoy Canterbury's with and without Supertweeter, ST 200 which costs 2 lakhs a pair on top of 10 Lakhs for pair of loudspeakers. The super tweeter at 1/5 th the cost was making big difference in performance and sound. They added air, the top end got smooth and the overall phase got spot on resulting in better imaging and staging. The speakers were running off Krell SACD Standard mated to Krell KAV 280P preamp and KaV 250 power amplifiers the cables used were Transparent audio. |
