The speakers were kept only room temperature conditions.
They have been used with great care, great power has not been applied to them.
All four speakers from the 2 speaker enclosures are in perfect condition.
The speakers were never out of place.
No component was not repaired nor replaced.
Rubber gaskets bass speakers are absolutely not degraded by time.
The speakers were protected from the sun.
Pigtails are original and not cracked.
Not tried washing them with water and no cleaning in any way and no solvents.
For the first time in their lives in 2014 front grille was removed from one of the speakers for examination and photography.
Speaker membranes are in perfect condition in 2014 were only slightly palpated for examination.
The rubber seems to have preserved the elastic characteristics at first seem easy movement of all stiffened .No sang for more than 20 years possible for 30 years.
It seems that require running as like widgets using for the first time.
It does not seem to present problems stiffening. Gaskets not softened at all. You have strengthened very little light pressure on the membrane .After I saw that seals are recovering from their initial stiffness
So in this period of 20-30 years they were not used at all.
Filters are also in original condition.
Housing is in perfect condition without penalty and without cracks.
Throughout the cat was left loudspeakers have been spared so
water and moisture.
In the past they were used with a pick up Tesla NZC130 with a tape mark TG674 Saba.
The loudspeakers were used to pick up radio cassette player with Philips brand were sold together.
Always have been used only for auditions, they were not used for drinking parties.
Year of production is somewhere around 1970-1980.
During the period they were used were not observed any abnormalities sound fle.
There were never tested to the limit.
Philips speakers specific sound from that period is very open, very Spring-Summer surprisingly alive.
However for a perfect fullness of sound I think that needs to be used with a subwoofer woofer.
