are these New Large Advent speakers worth considering?

Don't forget the toilet paper tube approach ... an invaluable tool to bring when trying to segregate sounds coming from the front of a so-called monkey coffin!
 
Here's the back of the Sherwood and the Yamaha:

Was hoping one of them had a pre out main in arrangement, would make it easy to use both receivers, one for each pair of speakers using one volume control for both. It can still be done using the record out on one connected to the aux in on the other, not as convenient, changing overall volume will require adjusting both volume controls. There are devices you can buy that will convert speaker output to line levels but that is starting to get involved. If you get the Advents you'll have something to play around, comparing. I think you'll like the Advents. The Sherwood, Sherwood's in general, are known for good sound, like Sansui.
 
The NLA uses ferro fluid in the tweeter the OLA does not.
The dome resonance Fc is an important value and I've posted on here that I measure very different
values from unit to unit probably due to different condition of the ferro fluid. I'd go with the OLA
unless you have a way to confirm the tweeter condition. On the other hand, see how they sound.
Also note that the NLA impedance drops very low in the extended position, better to run the
tweeters in decrease.
I have threads on here with tweeter measurements and plots of the input impedance.

lol! I had a paper towel roll in the car so I took out the tube and tore it in half. Then I forgot to bring it inside the house, so I had to put my ears up to the tweeters anyway. They sounded good.

OK, I don't know nuttin' about ferro fluid or values or extended position. By running the tweeters in decrease, do you mean the swtich on the back? The KLH has that too and I have them on decrease because the Infinitys are so high-pitched. These Advents sounded really good in the guy's small room, so I bought them and just got home with them. I'll bring them in as soon as I recover from driving 200 miles on the 5 -- boring and noisy but fast.

Oh yeah, that sounds too complicated for me. The speakers sounded so good with one of my CDs, much brighter than the KLH, not as harshly treble as the Infinitys, which they're replacing. So I bought them and just got home with them, I'll be getting them hooked up soon. The seller has another pair just like the ones I bought but with darker wood and black grilles. He said he's sold several of these Advents this year -- he'd bought them years ago when he thought he'd have enough money to buy a house and set up some elaborate system, but that never happened, so they've been sitting in his basement "cool and dry," he's been playing them about 6 months mostly for watching movies. He said the speakers would sound even better with new capacitors (haven't looked those up yet) and something else...resistors? But I'd need to learn how to solder, which I haven't done since metal shop in 7th grade. And maybe refoaming -- I don't know what the symptoms are for needing refoaming. Or they may sound good enough that I'll just let all that go for awhile. And I won't be paralleling them right away, I'll see first how they sound as-is. He said he never did that, hooked them up serially (not sure what that is, but probably means normally), but his amp is 150 watts, mine are 48 and 60.

Hook them up to either receiver, I'd use the Sherwood because I'm partial to their sound. Tell us what you think. Describing them as brighter than the KLH but not as much as the Infinities is what I would have expected. Live with them a bit and see what you think.
 
All four speakers are now playing from the budget Yamaha A-S301, which got some good reviews for its surprising warmth -- I'll switch to the (also budget) Sherwood S8900 tomorrow. On our (budget) KLHs and Advents, we're listening to a CD of "Alina" by the Estonian composer Arvo Pärt, on ECM. If you haven't heard it and like classical music, give it a try. It's not Bach or Beethoven. It's spare, and mesmerizing, a perfect antidote for these frenetic days we're living in. It could bore you or put you to sleep, though it woke me up when I first heard it: One night when I lived on Kaua`i, I'd gone to bed and left public radio on and fallen asleep; a shower moved in, as they always do, the raindrops were pattering on the ti leaves outside my window, this music was playing, it was as if the rain was set to music, and that's what I awoke to at 2 a.m. I will never forget it.

The music is a real test of the range and clarity of speakers because all the notes are separated from each other, like raindrops, from deep bass through mid-range all the way to the far right end of the piano keyboard. There are five sections, two of "Alina" with solo piano, and three of another work, "Spiegel im Spiegel", with piano and violin. The sections alternate. It's called tintinnabuli style, and the sounds truly are bell-like. And yet I have the high-frequency switches on all speakers turned to decrease.

And these speakers, the KLHs matched with the Advents, bring out these slow, lasting notes like I've never heard before. They rise and rise, and then the pianist gently hits a single, deep, resonant bass key. All these individual notes, up and down the scale, with wide spaces between them, I'm hearing them now almost like I heard them the first time when they woke me at early that morning. The next morning I called the radio station to ask what that piece was, and I've been listening to it ever since. I turned my girlfriend-now-wife onto it and she loves it just as much; she bought her own copy in the two years before we married. I'll give a listen to some of my favorite contemporary folk-roots artists tomorrow.

There are certainly speakers and amps that could do better, but probably not in my price range, so I'm really pleased with these and glad I took the drive (and that the fast lane on the 5 was 80 mph almost the entire 100 miles back home), and really glad that I first learned about these Advents and more about the KLHs right on this site, and thankful to people here who are so generous with their advice, suggestions and experience. The Advents sound so good so far that I may not even bother with caps and foam and paralleling -- I'll decide after I listen to other music. Anyway, thanks everybody.

...But I'm thinking of connecting the two sets of speakers only because of what I've read here about paralleling speakers, which I'd never heard of before and had to google to find out what it is. That it reduces impedance (ohms, right?) and lets the system produce better sound at lower volume. Yes? And less strain on the amps -- the Sherwood is RMS 48 watts x 2 and the Yamaha is 60 watts x 2. So not huge power, and driving four speakers like the KLH and Advent would be easier for the amps with lower resistance, and the amp specs also show higher wattage with lower ohms. And daisy-chaining does the same thing a different way? Tell me if I'm wrong -- I want to know. And I don't want to damage the amps or speakers -- the Sherwood specs are 4 or 8 ohms, the Yamaha 2, 4, 6 or 8 ohms. All four speakers are 8 ohms. Can I damage anything by paralleling the speakers?...

I would say parallel = more strain on the amps, while series wiring = less strain on the amps. If you go with parallel wiring or low ohm speakers, pay extra attention to the ventilation of the amp. No closed cabinets! Maybe even add a fan.

It isn't clear to me why you even want to run two pairs of speakers. Are the pairs in separate rooms? Is one pair making up for a deficiency in the other pair? Do you simply want more sound?
