re: Conway II

I bought my Conway II's in 1980, from Forum Hi-Fi in Coventry, for £200. (In 2014 this equates to over £700 !). In 1998, the bass drivers were suffering from "Foam Rot" around the outer edges, the grilles were getting jaded also. I sent the drivers back to Castle for a re-cone and also ordered two new foam grilles. They are still perfect to this day. I did have a cone rattle off a midrange unit at low volume. on investigation, I could find no unstuck loose parts. The speaker is 80mm, I decided to replace with 100mm speakers, mainly for the mounting holes. I decided on a pair of Mission 75 watt 100mm units. After filing out the the fixing holes, they were fitted and connected up. They only have to contend with 750Hz to 4KHz, to my surprise, they were balanced, smooth and detailed, all for the cost of under £20 inc. carriage.
The crossover has a fuse for each unit, I use 1A for bass, 800mA for mid and 500mA for tweeter, all fast blow.
I note the two midrange removed are marked ||/78, assuming this could be February 1978, and also ex shop demo speakers, they have lasted quite well.
