Pottrzebuję waszej porady mogę się zamienić na następujące kolumny :

Tannoy lancaster cabinets with 15" monitor gold Ref LSU/HF/15/8

tannoy berkeley mk2 with 3828, brand new cone/ coil assemblies fitted ( upgraded to 3838 spec)

i tu pytanie czy driver 3838 jest lepszy od 3828 ? Byly takie same na ebyau podaje linka

Tannoy

3836 15" ( same as used in grf memory and westminster with dual

magnets) WITH CUSTOM CROSSOVERS in lancaster cabinets

Powiem tak ostatnie wydają mi sie najciekawsza propozycja ale mam watpliwosc co do drivera bo w necie sa informacje :

Westminster using 3839W 15" Dual Concentric

GRF Memory using 3839M 15" Dual Concentric

A jedyne informacje na temat oznaczenia 3836 jakie znalazlem są następujące :

CONTRACTOR SERIES

Also in 1990 a new range of Wildcat replacements were introduced using more robust versions of the Duals developed for the System series. These cabinets were designed specifically for the sound and video contracting market providing very high sound quality with unequalled robustness.

An innovative cabinet was designed with a trapezoidal shape incorporating an aluminium extrusion housing integral flying points to suspend the cabinets safely above an audience. The whole suspension system was rigorously safety tested and has a national certification of safety. The Contractor Series was given the code system in engineering of CPA and this has stuck with the development right out into the marketplace.

The range consists of:

-------------------------------------------------------------------

CPA 15 using 3836 15" high output waveguide Dual Concentric in a trapezoidal cabinet.

-------------------------------------------------------------------

CPA 15FM using 3860 15" high output Waveguide Dual Concentric in a compact cabinet.

CPA 15.2 using 3861 two very high power 15" bass units in a rectangular bass bin.

CPA 12 using 3134 12" high output waveguide Dual Concentric in a very compact trapezoidal cabinet.

CPA 5 using 1501 5" ICT Point source drive unit in an exceptionally compact easily mounted molded cabinet.

Of the range the CPA 5, the last one to be introduced in May 1991 at the NSCA Show is worth further investigation.

The HF unit of this tiny driver operates on entirely different principles to all the other Tannoy drive units. The HF driving diaphragm has no coil, but a 'skirt' projects from the bottom of the diaphragm. The skirt is immersed in the same magnetic field as the LF unit coil and energy is induced into it from the LF coil. The crossover point can be set by the LF coil parameters and the diaphragm diameter. Eddy currents in the skirt which acts as a shortened turn similar to transformer theory effectively drive the HF diaphragm. The unit is therefore exceptionally robust with no possibility of HF burnout, a common problem with systems of this size and use.

Przepraszam za wklejenie całości ale uznałem że lepiej podam wszystkie informacje. I co wy na to do powyższych propozycji i zgodności driverów ?

Pozdrawiam serdecznie
