Sexy looking speakers there, Dave, and with some technology at work. Dovetailing the cabinet is meant to reduce standing waves in your enclosure and having your tweeter sit somewhat atop your cabinet is meant to reduce diffraction. SOME diffraction. Were I to make what I make for your speakers they would follow the contour of your tweeter mounting plate (tho nearer the driver) below the top of your cabinet and extend out to the edges of your cabinet and to the top of the mounting basket of your mid/bass driver.
Out of interest, what would such a package cost, shipped to UK, and would it be necessary to get into the speaker cabinets to install them as there does not appear to be any ready way in that I can see, no screws or other fastenings. Then you would have NO reflection off your baffles and no discontinuity to info produced by your tweeters. But, honestly, while I am confident you'd be the happier for it, I can't say that is why you are hearing your speakers as sources. From the looks of them, I wouldn't think you would be. But, I am curious about the possibility of a discontinuity to the output of your tweeters- well, not actually the output, rather what happens to it- having them split that way.
Talk to us about your toe-in, the distance to your listening position, what, if anything (eek!), is between you and your speakers.
Speakers are 8' apart and the listening position is 8' away from each. Toe in is such that each speaker is 'aimed at' the listening position. Tweeter centre is 40" from floor (ear height when listening). I have tried a variety of combiations of toe in and distance from back wall - thes have made some differences but I am yet to find a 'sweet spot'. Your disc player in phase?
I haven't a clue as to what that might mean or involve but I can advise that most of my listening is sourced from a Sony Vaio MM PC, mixtures of compressed and uncompressed files, USB 2.0 routed through a Beresford 7520 DAC to a Marantz PM6010OSE KI amp and no matter what is the source (TT, DVD-A, CD or PC), it doesn't seem to make any difference to that aspect of the listening experience. All your wire correctly hooked up?
To the best of my knowledge. I have used one of those 'Set Up Your Hi-Fi' CDs which told me everything was fine. And a photo or a diagram would be most helpful if you could provide it.
On their way but it might take a day or two.
Btw, those stands on the Mezzo page at the site are Atacama's and cost only about a hundred bucks US.
My stands are home made, from pine, design copied from RC60 de luxe stands which got a decent write up in the UK press. Had to go this way due to WAF - she doesn't like 'industrial, oil rig' looking bits of metal in her home , which is fair enough !
