The Polk Legend Series is coming

Very nice!
Thanks for sharing that Mike!
I love the look of these these with the grills on.
These are big and wide speakers that will take up a pretty good footprint and I am curious if, like other SDAs, they will need a good bit of space from the side and rear walls and also between the speakers themselves.
I cannot wait until people can start getting ears on them and sharing how well they sound. I would have thought that Polk would have made these available immediately after the reveal, to build on the hype, rather than having prospective customers wait almost 2 months from the reveal date until the date of release. Is that a common way of doing things in the audio world?

I can only speculate, but in my biz (automotive) there are a lot of activities happening simultaneously. Marketing, trying to generate buzz and hype, while engineering is still solving technical issues, and manufacturing gearing up for production.
The goal is to have full production up and running, and available for sale, at the time of maximum hype and demand.
Since these guys are made in China, it also takes some time via cargo ship to get here as well (~ 6 weeks on average). So IMO it seems about right.Basement: Polk SDA SRS 1.2tl's, Cary SLP-05 Pre with ultimate upgrade,McIntosh MCD301 CD/SACD player, Northstar Designs Excelsio DAC, Cambridge 851N streamer, McIntosh MC300 Amp, Silnote Morpheus Ref2, Series2 Digital Cables, Silnote Morpheus Ref2 Series2 XLR's, Furman 15PFi Power Conditioner, Pangea Power Cables, MIT Shotgun S3 IC's, MIT Shotgun S1 Bi-Wire speaker cables

What's common is an announcement at CES at the beginning of the year and no product available until the 3rd -4th quarter of the year. Two months is nothing, IMO.I would have thought that Polk would have made these available immediately after the reveal, to build on the hype, rather than having prospective customers wait almost 2 months from the reveal date until the date of release.

Another snippet from Mark Henninger at AVS Forum (post #57):
"I sincerely feel that at $6K per pair the Polk Legend L800 towers are the best value true high-end flagship tower speakers at RMAF 2019.
After-show listening to tracks of my choosing cemented it... The imaging these speakers are capable of is mind-blowing, easily putting sounds way far outside their physical separation. Blaze Mountain from Sounds from the Ground's new album Binary had sounds that seemed to literally be to my sides, that's how far the panoramic imaging stretched! But the speakers themselves are conventionally positioned.
Nothing else I heard here imaged like these."

I like the base in Figure 6A and 6B much better than the end result, which I find very odd....even ugly.Political Correctness'.........defined

Figure 6A and 6B look to be an RTA configuration... And closer to the prototype that I saw (there was no push out for the tweeters and mids as you see in the L800).
-
Yeah I'm reading through it now.

The patent gives a full explanation of the objectives of the new SDA-Pro design, and the compromises inherent in previous iterations of SDA in speakers. Especially shows the specific goals of the new design and why it's different from the old (very important for showing why it's a new invention that is patent worthy) including why it has two tweeters per cabinet successfully deployed now for a broader frequency range for SDA. The patent does call SDA-Pro a set of effects though. Should be patent covered for another 20 years now.

Yeah it was very interesting to read the references to the original dual tweeter design, and the limitations. Very cool history.
Looks like the new approach overcomes that! In addition to the broader frequency range, they claim a larger sweet spot!

I thought I heard Stu explain in one of the vids I watched that the SDA signal actually moves into the tweeter and they found it to further enhance the technology. The entire frequency range of the tweeter is not "SDA'ed", just a portion in the upper midrange it handles.
If sales are brisk enough, I can see them producing a model with a single woofer and adjusting cabinet size accordingly.No excuses! -
Some interesting comments in there about placement. This image shows that the stereo drivers are to aimed right at the listening spot!

Ok the complete crossover schematic is in the patent. They are actually not running the dimensional tweeter full bandwidth like the stereo array tweet. The crossover for the dimensional array is identical to the stereo array with the exception of an extra paralleled inductor/resistor combo that serves to gradually roll off the top end of the dimensional tweeter.The re-introduction of the dimensional tweeter is also interesting. I understand the use of the tweets in 1st gen SDA's caused some undesirable artifacts.
-
Interesting that we've essentially extrapolated these SDA limitations without seeing it on paper.
Also interesting, the angled tweeter baffle is forward of the woofers.Post edited by westmassguy onHome Theater/2 Channel:

If these sound as good as it's been written, I'm afraid to audition them down the road. It would mean saying goodbye to my 2Bs....not sure I can do that. Of course, I could win the lottery and it would then be a mute point.Yep, my name really is Bob.

I was thinking the same thing, and would have preferred these designs too. With the final build it looks like the speaker is hinged on the front baffle, like one of those old spring-steel S-chairs. I know it's rear supported, but had half a thought along the lines of, well that's gonna snap right off.I like the base in Figure 6A and 6B much better than the end result, which I find very odd....even ugly.
But... I'm really intrigued with these 800s. Love those dual 10s, wow. Fat and beefy. I can only imagine what they do to a room, especially with the PowerPort.
Is PowerPort a patented Polk proprietary design? I haven't seen a lot of other speakers, so I'm not sure if anyone else does something like this.
I just heard the 800s are on sale right now on Adorama, with free shipping.
I disabled signatures. -
Ha, anyone with a Sound&Vision account wanna school this guy in the comments?

I disabled signatures. -
I gotta be honest......sans grill, the L800 kinda looks like a frankenpolk experiment with JBL's. With grills, better. Not good, but better.
The angled baffle, as Hardy points out, is not a revolutionary idea....
That all being said, man, I can't WAIT to hear these. I wanna, I wanna, I wanna.......and while 6K isn't chump change...at this point in life, it's not out of the question either.
How will they compare to old SDA? Ok, pull out a pair of old Monitor 7's (Not a fan of the Monitor 10's) and compare them to a pair of LSiM's. Probably hear the lineage but they are fundamentally different sounding speakers. I think you could possibly draw and analogy there. My PERSONAL opinion is that the newer Polks LSi's/LSiM's were "better" speakers but more clinical......my old Monitor 7A's and SDA's were more musical. I'm not knocking the new stuff but the older stuff, the edges were rounder, if you will.
Now, we've had this argument through the years and is one of the areas that F1 and I fell into different camps. I was solidly in the there will never be another 2ch SDA speaker. The world had passed SDA and 2ch by and Polk moved on to a "move boxes" and satisfy the masses company. Again, not a criticism as they continued to make good gear....but I didn't see them ever making boutique gear. Especially since the boutique buying segment were never accepting of SDA anyway. Even the folks at Polk, SDA junkies to a person, conceded that they didn't think the market would support it. Matt said so himself in Doro's kitchen back in '05.
F1 always maintained that it could be commercially viable in a certain segment. Well, apparently F1's logic and/or insistence found roots someplace in the current Polk hierarchy. I shudder to think at the number of knee pads he wore out.....I digress, so, we shall certainly see how this pans out and I couldn't be more excited.
Personally, I think F1 should get the first pair off the line from Polk.
Just my .02.
BDT
P.S. I used to have a TON of Polk Bucks back in the day.....I wonder if they are still valid? Heh, heh, heh... -
Apart from the geniuses who worked at Polk on the new speaker line, and those who kept faith with the SDA concept, I suspect a lot of credit for bringing SDA out of the interesting concept phase to a marketable product belongs to Sound United. It takes some financial muscle and risk taking to back a 3 year product development cycle resulting in a product that won patent protection again, and it was apparently beyond Polk's capability as a standalone company. Now they just need to rebuild a dealer network. That may be the hardest part!

Regarding Focused Image Geometry, the S&V poster is correct that it was an attempt by NHT to address crosstalk and time alignment. It was also possible to do so by simply toeing a speaker cabinet in. What was notable about NHT speakers back in the day is that they were early on the market in building a very large speaker cabinet with large woofers in a very narrow profile. Other companies adopted some of the same ideas. But, SDA is much more than the poster realizes.
