The first full-range Diatone speaker was born in 1947 with the name P-62F. During 1950 the P-65F was introduced, then the P-60 in 1954. The P-610 was introduced, as a natural evolution, in 1958, with two versions named P-610A and P-610B, respectively with 16 and 8 ohms coils. During 1979 a new version was born, with the name P-610D, the Alnico magnet version, and P-610F, the ferrite magnet version. Again (both) with suffix A or B (that is 16 or 8 ohms coils).

The main characteristics of P-610DA and DB are: nominal diameter 16 cm, Alnico magnet, 7W nominal power and 20W max power, paper cone, 7 gr. moving mass, 12000 Gauss in the gap, moving coil of 19,2 mm diameter. Sensibility is 90dB/1W/1m while frequency response is up to 18 KHz. It has a foam surround.

In 1995 Diatone wanted to celebrate the 50th anniversary of this speaker with a special new version, named P-610M.

Again, the suffix A or B was used for distinguish between the 16 and the 8 ohms versions. The only difference between the M and the D version is the surround, now in leather.

P-610M is out of production since january 1997 and no more Diatone full range was produced or designed.

AudioNautes can no longer offer this speaker stand alone. However, it is available, in very limited quantity, the complete speaker S-1LE (with P-610MB).
