sorry about the late reply
i did not realise this thread had been moved over from fullrange
still loving the speakers
i bought the drivers after many late nights on the internet drooling over old altec and tannoy speakers
never heard any altec drivers before so i just jumped in and hoped for the best ,i have to say i,m glad i did and would not hesitate to reccomend these drivers
as for gpa audio,s service though i,d have to give it a thumbs down
you can purchase all gpa,s range on ebay
