Apologies for this but I haven't had my Shredded Wheat this morning: Phased arrays - how do they work again? In my experience un-phased drivers sound crap, so a lot of un-phased drivers are going to sound really crap, ergo the likelihood is that a manufacturer of speaker systems containing a dearth of drivers had better be sure they are all wired up in phase. I realise my ignorance is blinding me here so please help me to understand where I'm going wrong  |

Not sure what you are on about Dave? The drivers are all wired in the same phase as the other like drivers. The crossovers are interesting but I can't see why they bothered with a circuit board when hard wiring would have been easier and better. They are far from 'cost no object' too - I built fancier ones for my Yamahas.

Indeed M cap's could have gone another route and improved matters further.
Not sure about the Infinities have owned three pairs, the space, room and equipment needed to really make them sing you could have easily made a more engaging sound for a lot less hassle imho

Not sure why he has them set up like that either. He makes a point of saying that the mid tweeter panels are dipoles and therefore produce nuls to the sides - he even says this makes them uncritical of the room - yet at the same time he has them so far from the side walls they are almost next to each other!

Think it was a lifetime dream to own them

Yeah, I agree and I can really see the fun in that. As a more objective report there are a lot of holes in it though. He says the old crossovers were pretty basic and later in the vid they show them. There aren't any electrolytic caps used in the original though so I don't see how the caps have aged. The biggest difference is in the inductors in that the new ones are large foil types and will have much lower resistance than the originals.

Only big Wilsons can do it, and they're just as expensive. My system is good, but it doesn't approach the scale of the Infinity IRS that I heard all those years ago. |

Martin, I have to agree. I had the IRS-1b which is the small (!) brother of the big ref V. Same arrays of emit and emim ribbons and separate active woofer towers with feedback control electronics keeping the bass under control.
They were excellent so I can only imagine how good the larger ones would be. The major weakness in mine which I suspect was similar in the ref V was the speed difference between the mid/high towers an the bass towers which was audible.
I've got to say Magicos have never done it for me and I have listened a lot to their best speakers in a very good system set up by a very competent system installer ( Allan Goodwin in Waltham, Mass). Their signature to me sounded similar to the top Focal speakers
I've been much more impressed by the Rockport range which seem to have an image solidity that the Magicos don't quite manage. The Wilson Alexandria too can portray a large scale soundstage in fine fashion. My own YG Anat produces a more resolved midrange than most with the ability to let more detail come through without any hardness which, for me, works very well. The addition of the Wilson subwoofer crossing over at 35hz gives the Anats the solidity large scale works need.

Alexandrias are impressive and have that sense of structural scale that I so like. Magicos sound like a very clean but polite copy of the music. Where's the soul?

I didn't follow Arnie Nudell's designs after Infinity . The Genesis speakers looked like a recreation of the refV for his new company. He used to get good coverage in The Absolute Sound, possibly because Harry Pearson used the Infinity refV in his Sea Cliffe reference system.
I suspect today's state of the art speakers probably offer better bottom to top uniformity than Arnie's big flagships however the Infinity and, I guess, the Genesis, probably had a weight and solidity of sound which is very difficult to match. Alexandrian or maybe the top Rockports are two of the few candidates to compete.

Yes, I know I'm being rose-tinted about the big Infinitys, I just remember what I felt back then when I heard them. I dare say that my Ushers would show them a clean pair of heels in all but the scale department, and at least they're only 160kg each! |

I still miss my Daleks, Leak 2075s
Assume they too will not deliver that well, but would be great to try
