Depending on which series W90 speakers you have, the cross overs will be different. My W90's are 1964 with the two pots and 6 possion switch on each cross over. Later model don't have the 6 way switch.

I believe my W 90's are 1964 models, and only the unvented rear panel is sand filled. There are two rear panels that cover the devided cabinets, and the right side (when looking at the backs) is the solid panel that is route and sand filled whith a thin panel over the route to contain the sand, and the left side cover is vented with slots going side to side from top to bottom. There is no sand filled panels on the outer walls of the cabinets or the divider panel. I did change out the Motarola style input jacks and installed Banana 24K plated jacks for easy of hookup and swapping speakers. These speakers sound wonderful compared to my W 70's, and my only concern is that my 60 watt per channel Dynaco Mark III amps may be too powerful for the W 90 and the W 70 speakers. I'm keeping the volume below 4 to play it safe!

As I recall, the largest in the series was the floor standing W90. The double enclosure with sand fill between them was designed to damp out all cabinet resonances and I thought it was extremely clever. I've always wondered why nobody else seems to have tried it. As I recall, the W90 was a dual 3 way system, having two 3 way 12 inch systems in the same enclosure. It was their most ambitious effort at that time. Wharfedale was always regarded as a very high quality British manufacturer and their products were distributed by among others, Lafayette Radio and Electronics. Anyone recall their main store in Syosset Long Island or their large branch store on Liberty Avenue in Jamaica Queens? In the 1950s and 1960s these were among the largest retail electronics store outlets in the New York Metropolitan area. Oh how I wish I had saved their large and fascinating catalogues. They sold everything from Audio equipment, to electronics parts, to microscopes and telescopes including their own brand name products. Brings back a lot of memories.

I need to find out if anyone can tell me what type of jacks were used on the W-90's, as I have tried banana plugs and 1/8 inch plugs but neither will fit into the small jacks(two on each speaker).
