Caveat emptor, I'm not a big fan of the 511e. I think the 805's have a much clearer and smoother mid. Just my opinion...
I have a pair of 805s. they seem to be more evenly spread sound than the 511s I've had. i can't imagine that putting a larger driver would change that.
You want to sell them? :)Quote:

Link doesn't work on this forum.
Look on Facebook

The link worked then didn’t but I found it, thank you.Quote:

Maybe a new facebook account is suspect? I don’t know except the request to join still states “pending”

Also, although this thread is about the 805…my trajectory is pointing to a pair of wooden 1005 horns, so experiences with the 1005B versus 805B are most welcome. :)
Again, look at the 1005 Vs 511 polar plots in the link I posted, it's much higher aspect ratio for 'fanning' over a large/wide distance, so better/'tighter' vertically, but since our hearing acuity isn't good vertically, mostly a moot point IME. Horns in general need to be at least ~10 WLs away IME, so the much bigger multicells are usually too big for most folk's homes. My original ~26 x 46 ft 'great room' was about right for the 805 and found that dual stacked 511s worked even better overall once tweaked till I built a huge ~63 Hz 1.5 way parabolic waveguide [WG] loadedwith the 511's dual 802-8A, 802-8G once critically damped.
Will look closer at the link…I bookmarked immediately. What I may not be understanding is I thought the radiation pattern was frequency dependent.Quote:

10 WL listening distance in my room is ~700Hz, if I’m understanding here.
Any pictures of the ~63 Hz WG? …or any of the systems you hot rodded in years past? Love to see them!
No experience with 805's, but have owned 1505's and 1005's both with dual 288's. The sonic mids to set the standard. Heard fingers and fingernails on guitar strings and bass strings that I didn't know existed on some recordings. I think that your idea of a tweeter in a cell was a great idea. If you get ten cells two over one down crossed right in front of you, would be the key, Got any slots ???
Thanks for the feedback…will probably place the tweeter on top initially and here’s a link to the 511Es I’m replacing and the tweeter that sits on top:Quote:

If you have coffee and/or side tables/whatever between you and the speakers, then ideally need to be covered with thick movers blankets for critical listening.
It's 10 WLs of the horn's cutoff, so for an 805 it's ~17.5+5.91+4 [guesstimate of a 288-8G's acoustic center] = ~27.41", 13543"_sec/4/27.41 = ~123.52 Hz
Anyway, 27.41*10 = 274.1/12 = ~22.84 Ft or if you prefer: ~13543"/274.1" = 49.41 Hz/12.52 = 2.5x or exactly 40% lower.
No, never had a good reason to waste filming costs on my DIY hobbies other than for racing and even most of those were ruined or disappeared over time and no holiday/whatever pictures ever had more than a snippet of either of the floor/ceiling stretched screen covers.
I've posted a write-up of my 'adventures' in tweaking every last drop of clarity, HF extension at my disposal [well equipped professional tooling machine shop used only for hum, 'very special' projects] out of a pair of 511 and responded to many cheap driver, speaker/horn tweaking posts on various forums across time/net, but haven't saved/cataloged them, so best I could do would be to scroll through 1000? or more posts still in various forum archives to find them, but life's too short nowadays.
Regardless, still got a dimensional sketch of the WG 'somewhere', but it's basically the width of a 211 horn minus venting, shaped in a 'V' to insert in the corners with a 1803's width turned vertical IIRC to get max practical horizontal polar control and a truncated 'V' cut to match the 211's for the dual 802s.
ok steve, I just have to ask, whatever became of the big the big horns ?
Storage…with a bud back in Alabama. Ungodly great horns…miss them of course. Need to make space down here in Florida.Quote:

Yeah, certainly not up to the tin knocker's workmanship, but if viewed from the fact that the horns were originally designed to get 12.5 kHz out of a ~7 kHz driver whereas nowadays the 288 and similar easily go out to 12.5 - 15 kHz, so throat 'finish' isn't so critical unless your hearing is good enough to perceive a dog whistle, hence the minor ripples in the extreme HF of these tiny edge mismatches.Quote:

and the females I used for this BW claimed it just made the recordings sound too shrill/dissident to the point where I had to roll off the 1.6 kHz EQ slider all the way down (-16 dB IIRC).
I’m in Lady Lake…pretty close!Quote:
