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

    Source: Audio magazine March 1972 , Vol. 56, No. 3

    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 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,

    The W80A was Wharfedales answer to the Bose 901. In it's description it said that it is was not sensitive to room acoustics and it has numerous ways to position the speakers, Today this is a very rare Wharfedale speaker, there is a demonstration of the Variflex speaker on YouTube and the person has it turned around and is playing it as a conventional speaker. It has an upward, or side firing 12” woofer depending on the speakers positioning. Upward firing woofers are not a good idea from an environmental perspective, imagine listening to beautiful music only to hear that something is bouncing around on the upward firing speaker cone.

    Continuously variable level controls for the tweeter and midrange. Can be orientated vertically or horizontally. The W45 was considered to be a book shelf speaker. My examples are horizontally positioned and they work very well that way with the woofer inside and the tweeter and midrange on the outside to increase separation. The W45 is a rare speaker these days and it is a real sweetie. The W45 is wonderful with classical, Baroque, small room jazz, lounge music, chamber music, etc. The W45 is not a tiring speaker to listen too.

    Continuously variable level controls for the tweeter and midrange. The W35 was Wharfedale's Quadraphonic speaker. Quadraphonic media was just coming out in 1970. The squarish shape of this speaker with it's beveled rear corners were were designed to be mounted on the walls in the corners of rooms using optional mounting brackets. This is a excellent speaker wonderful clear interior articulated sound, the British sound, it differs from the W45 with just slightly less bass extension. with music like chamber music, string quartets there is very little difference.

    Continuously variable level control for the tweeter. I once had this speaker and the W25 was the AR killer for me. In 1973 I had a pair of AR-7's the W25's blew them out of the water. Not only did they sound better but they looked better. While the AR's sounded good I have always thought they were ugly to look at. Wharfedales of that time had beautiful cabinetry.
