Like many continental European products, Philips speakers have never met the favor of Hi-Fi magazines and reviewers.

Philips, as well as Grundig, Saba or Telefunken was considered the typical brand suitable for consumer market because essentially producing radios and televisions.

For this reason, the only systems present in an audiophile's living room were the American, Japanese or English.

However, we must not forget that, compared to small English producers, often one-man companies, the Philips, Grundig, Saba and Telefunken had immeasurably superior resources and know-how.

 After the big result obtain with the upgrade on 22RH457 model I have buy a pair of 22AH495 in good conditions.

This is a three-way 55 liter net volume with a good 12" paper woofer (AD12200).

The medium frequencies are reproduced with a 5 cm dome midrange (AD 0211) and the high with a 1 inch tweeter (AD 0164).

The original crossover frequencies are 750Hz and 5500Hz.

The components are of good quality but the construction leaves a lot to be desired, at least by actual standards.

In particular, in the crossover there are electrolytic capacitors which are at least 45 years old and which, in fact, when measured showed completely altered values ​​compared to the original design.

Like the 22RH457 model the strong point of this speaker system is the large dome midrange which ensures incredible dispersion compared to a cone. 

in recent years the domed mids are little used probably to avoid crossovers between the speakers in the vocal range but try listening to ATC speakers with their very expensive 75mm medium.

Compared to the 22RH457 model, the 22AH495 model uses the latest generation of speaker drivers and on the midrange and tweeter they have switched from paper to textile.
