In Reply to: Can I suggest you arrange an audition of some 57s. :-)) ... posted by andyr on September 11, 2012 at 04:01:04:
Hi Andy,
I intend to, but I am told their sweet spot is about 1 person wide, even when positioned very widely and angles in. This would not be acceptable as my wife and I like to listen together. The Audiosphere Model 3 have a sweet spot about 1.8 people wide. I am told the 63 'family' can also do two listeners who like each other.
It's also our lounge-dining room, L-shaped.
The widest I can get any pair of 'decent-bandwidth enclosure type' speaker's centres apart is about 9.5 feet, and less than 9ft with ELS. With these fairly directional dipoles I still need to i) have them wide enough for the above, and ii) with their sides close to the wall to get good bass iii) AND angled in enough to cross in front of me/us. And iv) there's the desirable idea of listening within the near field, which further reduces the width of the sweet spot. An 8 ft or less listening distance.
So far, angling the 63s in too much increases the amount of early rear reflections, despite my primitive diff/sorbers. ;-)
I am told the 63 family can do two listeners who like each other. ? Well not yet or not quite, so far.
I might even be able to persuade one person to bring a pair of 57s over. And I have some ribbon tweeters.
..... we'll see.
For deep bass I'll see how it goes with four Audiosphere 3s, distributed 'en arc' with the ELS and one behind me/us - for 120 (or lower) to ~30hz. IF I really need it, for a while anyway. :-)!
Dipole bass? IF I decide dipole bass under each ELS is vital. Two ~ 15 to 18 inch high open baffles/H-frames each with four of the cheap blue-coned Pyle 12" woofers. Arranged 2 by 2 clamshelled working into a central slot (ala Celestion 6000). Likely in H-frames with a slot through the middle, open to each side. The H-frame aspect reducing the amount of Eq required.
Electronics for bass? A 100wpc HK 801, some Eq / Qts Rs, ELF hp filtering and a steep low-pass. Shallow high-pass on the ELS if any, as I will be experimenting to fill in any floor-reflection-dip I can hear / measure.
At the distances involved I'm hoping the band-pass of the floor level bass drive will be down below the dip, and that I'll be able to stop the ELS driving the dip or do some overlap/eq. Again, we will see.
My possibly defunct plan for 'my last house-sized speakers' would use stacked spheres, avoiding the dip was built-in to the approach.
The Aussie ELS kits are a real possibility, still.
