I have Mordaunt Short Aviano 1 fronts with a Mordaunt Short Alumni centre and am yet to hear any problems. They are from the same and use some of the same components and are a tonal match also.
I know people say its best to have them all the same, and I'm sure it is, however, my front three sound great and mix and blend with no problem, at least to my ears.
You are not alone.
I have the complete Tannoy Sensys AV range, but my centre speaker is on a Custom shelf above my TV around 22 inches from the back wall, but the sound never matched the main speakers as it was always lacking treble would be the easy thing to say just no air, but my large main speakers have loads of bass with loads of air, so I brought a replacement tweeter for my centre speaker thinking it was a bad tweeter, well it was the same and I checked the crossover everything was fine.
So around 3 weeks ago I thought I would buy a new centre speaker, so I brought the same one from hyper fi just to see if a new one would be any better. Well they sent me the wrong speaker, they sent me a Tannoy eyris centre, anyway I will get to my point, this speaker sounds more open and a lot better matched to my other speakers then its matching one.
So I am happier with this speaker then the matching one, yes it looks different, but sounds a hell of a lot better.
