The AR-3a is superior period.These speakers were only made in the AR factory at Amersfoort - sold in the UK and Australia etc.I believe this was a failed experiment and consequently not released in the US...The are at least two areas where the speakers differed:-(1) - The obvious one is the capacitors in the crossover are the cheap and nasty E-Cap (By now they would be leaking)(2) - The less obvious area is the 'AR-3a' used copper for the mid voice coil former and the 'Improved' used aluminium.I have been using tri-amping (active) systems for about 30 years this is a real improvement. Most noteworthy is the bass.An other consideration is there may be a requirement to modify the cabinets to accomodate the additional amplifiers (maybe the amps don't like their earths connected).RegardsBarry Hart Link to comment Share on other sites More sharing options...
