Like all Hi fi its a never ending process to bring about further improvements and I have been trying for about a year to see if I can improve on the Saba Greencones. I persuaded myself that I should be able to improve on midrange drivers costing about £150 and about 60 years old. Surely hi fi had moved on in that time! Its been a long journey but finally I found the Cube Audio FC8s albeit at ten times the cost of the Sabas. They replace the midrange and tweeters with a point source driver.
I just have the job of integrating them perfectly into the baffles. They extend further up and down the frequencies than the Sabas so 'crossovers' will need some tweaking.
