OLC question mark

The thread starts: By this I mean single transducer drive units that cover the whole audio band, nothing with a separate tweeter (or sub for that matter).

I have owned and used full range drive units from Jordan, Elac, Coral, Goodmans, Jordan Watts, Coral, Eagle, Lowther, Fane and many others. Currently I have (as some of you may have seen) just aquired a pair of Chinese 'Aucharm' 6 1/2" single cone, full range Diatone copies.

My experiences with the various mentioned drivers varied a lot.

The Jordan Watt modules had great potential, but driver design drawbacks prevented them from achieving what they might have done. The chassis enclosed the cones too much, causing colourations.

I did not get on with the Lowthers (two pairs of Acoustas with square frame PM6 units in), they may have been spectacular, but they were horribly coloured.

The best were the Coral Beta 10 units, which were truly fabulous, followed surprisingly maybe, by the little Eagle FR65, a very nice quality twin cone 6 1/2" driver, rumoured to also come from the Coral factory in Japan. I tried the larger 8" Eagle FR8, but it did not sound as good.

I've used reflex and horn enclosures with full range units, but don't have a preference, rather, going with what seems to suit each driver at the time.

Has anybody got any experience of these types of drive units and if so what did you use and how?
