Hi Daniele,
I was just at Sound Lab … really rare and interesting timing, but he has a pair of same speakers in from a customer to give them a ‘face-lift and fix up’ – but they sound great just as they are …. not sure if you have seen them without the grill cover …and to note the high frequency … you may want to have them position so highs are on the outside to give wide sound stage (opposite as this photo shows… up to you to experiment. Hope all goes well!
(I’m not so important, but you might like to see Roger who is the inventor, designer, brains behind all of Sound Lab.)
