Are these as fussy with placement and partnering equipment as seller implies?
Seems like they would be hard to set up in your average living room!

Hyperbolic sales patter.

Back in the day (late 80s, early 90s) Manawatu TV and Sound sold a few of the 3 ways and smaller 2 way speakers, I got to hear them on a regular basis.

Later there was a floor standing version but I never heard that.

The setup paragraph applies to all speakers, not just Genesis.

Forget bi-wiring, they were sensitive to cables though, Tv and Sound used mainly Kimber and Plinius amps (Plinius was the importer).
More important to leave those rear level controls alone !

They could sound pretty good with nice powerful bass, good focus, with a soundstage firmly confined to the speaker's dimensions.
Tonally it was all a bit dark, airless and not particularly transparent.

Decent enough but not a compelling purchase.

IIRC the original retail was ~$5k.

So, looking at circa 30 yr old spkrs then, original cost circa $5K, which makes the listed items somewhat overpriced!

All his stuff is over-priced !

I've written before, hinting that I can't believe in (old or new) claims of, classy or not, so-called high-end speakers of the era, in a straight edged box.
Especially ones like these with a giant thick overhang above the tweeter (and bottom) just to accommodate a cover.
I'm influenced of course from reading from years ago, Lynn Olson writing about his development of his Ariel loudspeaker pair.

" As I mentioned at the beginning of this article, a box is a terrible shape for a loudspeaker. After all, a loudspeaker operates at the speed of sound (not a figure of speech), and what was the last time you saw an airplane that looked like a box? Just like an aircraft, sharp edges and bumps create shockwaves at the rough spots, and these shockwaves create drag in an aircraft and secondary reflections in a loudspeaker. Since these reflections have delays comparable to the delays created by the head and shoulders of the listener, the edge reflections confuse the stereo image, flatten the depth perspective, and create listening fatigue.

The truly correct approach is to use gently sweeping aerodynamic shapes, resulting in speaker cabinets with large-radius curves at least equal to the radius of the midrange cone. Gee, you might think, nobody does this. Why? Cost and cosmetic expectations. That's all."

Why not lose the grill cover and sculpt the top back in a curve as well (as the sides)?

I suppose a new owner could if so inclined, but then back to actually how good even so it could be, and the expert experienced reading review from MW. ;=}))

Anyway, still interesting to see and read about;- thanks for the link! ;- )

I've experimented with success using  pressed wool felt to deal with baffle diffraction issues on an earlier set of speakers that I'd built.  

I'd not bothered with my current set up as I didn't think it was needed but this thread has prompted me to try them out with interesting results.  Nor sure where I got the idea for the diamond shape cutout but must have been recommended somewhere.  The top end has lost too much sparkle for my liking but there is an improvement in upper midrange vocals. I do have more wool felt and feel this is with pusuing so will experiment with different size/shape cutouts.

Your speaker has a relatively narrow front baffle, the felt is too much of a good thing ?

Another way to beat diffraction on a large box is to facet the front baffle like Avalon.

Maybe that's where you got your diamond shape from ?

Actually you may well be right!

One of the DIY speaker builders who's work I follow (the first set I speakers I built were his design) was involved with Avalon Audio and I believe was responsible for their speakers in the early days.

He is currently in the process of updating his DIY version of the Isis.

I'd love to have the skills to make something like this but the thought of building that cabinet would give me nightmares, maybe one day...

Nice !

Not heard or seen the Iris, just some early, smaller models.

Excellent speakers except for putting the speaker terminals on the bottom.

Doh !
