I run two sets of Speakers myself at present, Stacked ESL's and Floor Standing Cabinets housing Audax Carbon Fibre Drivers for both Mid and Bass with a Audax HD P4 Gold Dome Piezo Tweeter.
The Cabinets are a coloured sonic compared to the ESL's but in comparison to typical Cabinet Speakers are on the transparent side.
I have the Cabinet Speakers mainly for adding a increase to the Richness of Tone to my sessions of listening to Blues Music, especially the performers who become mainstream as Chicago Blues Artists.
Additionally, I have a full set of drivers stored to be used to produce a OB Speaker.
Drivers have gone through the roof in purchase prices in the past few years.
I certainly would not own all the drivers I have at present in storage if I were to collect them in todays market.
