Here are the specifications for the Achromatic line of Wharfedale Speakers as of 1972.

The Achromatic line up were Wharfedales move into acoustic suspended speakers. I have never had the opportunity to listen to the ported Wharfedales from the 1960's but to my ears (wish I still had those ears) back in the early 1970's the Wharfedales were the equal if not better than the Acoustic Research Speakers of the time when similar models were compared. Note the maximum power levels. Keep in mind audio amps did not have the actual power levels of today's rigs. Going the vintage route solid state wise is a waste as so much of it was junk there are exceptions to the rule. My brother's Sansui AU-9500 is an example. The JVC Super Digifine integrated amp I once had was another example. The best bang for the buck today is a quality Class “D” audio amp. I have been reading about them in the Audiophile blogs and it interesting to note these amp have the characteristics of a class “A” amp but are far more efficient. I can tell you first hand the Dayton Audio DTA-120BT class “D” amp and my W35's and W45's is a fantastic match. It is so nice not having to worry about over powering these W's,
