ADS-910's

Yeah, I have the knobs but no stands. They do make good handles for moving the speakers. Those suckers are heavy. I assumed you need the knobs to seal the cabinets, but that could be wrong. I'll have to take a closer look.

I did try running the 910s with the Dahlquist DQ-10s and that sounded pretty good, but I did not have much time for listening.

I would guess the 910's would over shadow the Dahlquist's, such big sound out of the 910's.
 
Two different speakers the 93dB sensitivity ADS and the about 85dB Dahlquist. The ADS unless used on an amp with reduced gain (input level controls turned down to match the DQ-10 level) will be playing loud enough to kinda keep the DQs from being heard.

Since the ADS are 6Ω nominal, 4 Ohm minimum and the DQs are 8Ω some amps don't want to see both pair at one time in parallel.
 
Often stacking, or listening to two pairs of same branded speakers sounds best. Once in a while odd brands can sound great, but usually just ok.

I was running the ADS and DQs on two different amps, so no problem there. I had not realized the DQs were so inefficient. They are pretty new to me. The ADS amp can be adjusted so in theory I could better match the volume levels. Unfortunately, I am 200 miles away in CT now.

I had hoped the ADS 910 and L710 would have sounded better together. It was a disappointment. Still love the 910s on their own. They kick ass, and don't need any help.

Yes they do!
I would assume the 710's stacked with 710's would sound great though.
 
I think the issue with Stacking is in Imaging, the high frequencies emanate from multiple places. For example on Richard So's website there is a picture of what appears to be stacked ADS L1590s BUT that is not what they are it is a single cabinet with a single tweeter with the midrange domes in an MTM configuration, I suspect if some of the people with some solid speaker design background show up they could do a much better job of explaining it than I ever could, but for what its worth, why would he not just stack 1590's it would have been a lot easier and i suspect its the issues i have had with detailed imaging at high frequencies becoming a bit diffuse

With regard to the Stacking of KLH Six's, and Six's with Seventeens and the Advents none of these have amazing imaging to start, the fried egg tweeters and the small cones on the KLH simply are not sharp enough to image as well as the dome tweeters of the Dahlquest (and super piezo) and the ADS but that's just my opinion mixed with enough knowledge/experience to be dangerous and maybe naive

That makes a lot of sense. Also when I stacked my Six's, I had them tweeter to tweeter, recommended in many threads on AK.
 
Yes tweeter to tweeter but still, the tweeters are give or take maybe 6 inches apart edge ti edge and 8 or so center to center? but these tweeters are diffuse not laser sharp imaging to start with and also assumes perfect phase (same length signal paths etc) , so you just add to a wall of sound

When I had my Six's stacked, I didn't notice any weirdness or phase issues with the highs. They sounded very good.
 
Yesterday we had the family over for a Father's Day BBQ. Had a great day.
I brought my brother down the hear the 910's, he had not heard them and didn't know the ADS name.
I played one song before they headed out, "One Chance" by Eric Clapton. If you don't know this song, do yourself a big favor and listen to it, loud!
For the first time with these, I had the volume at the 12 o-clock position. OH MY GOD! Together, we stood and listened with our eyes closed. Eric was in my basement, live! We were dumbfounded at the incredible sound and performance of the 910's. Yet again, these deliver! They were barely breaking a sweat, the woofers barely moving, yet the bass was do deep and tight.
Just more praise for these incredible speakers.
 
Woofers are really supposed to be moving when you are looking at them. That is an indication of very low frequency info usually from the turntable. That 20Hz stuff is 20 times a second for the movement of the woofer. Hard to see that so that is why woofers aren't generally seen to move with other sources.

A woofer making large excursions is an indication of a need for a subsonic filter to save the woofer and the amp power wasted to make that movement.

Good tune to get your brother introduced to the sound of great ADS speakers.

The woofers were moving, but excessive excursion was not. I would say I was seeing maybe 1/2 inch movement if that. I'll have to check, but I don't think the sub-sonic filter was activated on the preamp. The source was digital through my Mac Pro tower through a DAC to the peramp.
The power of the M-7050 drives these easily, and barely gets warm, even after hours of playing.
And agree, a great tune. He and his wife live in a condo, so he cannot crank tunes at all. They are looking to buy a house in the next year or two, and will be very happy to have a place where he doesn't have to worry about neighbors.

Had the opportunity to demo the 910's to an AKer this weekend. He came up from NYC and bought my KLH Twenty Threes and Pioneer TT. After listening the KLH's and TT, I brought him to the cave to demo some gear, and speakers. He was quite impressed with the 910's. Played just about every set of speakers I have there, and he also liked the Angelica's a lot, but the 910's were the star again!
Happy 4th everyone!
 
I hope everyone had a great 4th of July weekend.
It sounds like the 910's are hard to beat. Did the AKer try to purchase your 910's? It was a good opportunity to demo some great vintage speakers. Did you play the KLH Fives?
I haven't really had a chance to listen to mine because we made a trip to Southern Cal. to visit with my daughter. We just got home last night.

Hey Curt,

Yeah, the 910's are at the top of my lineup. I'd say the Angelica's are next.

He came up from NYC to buy the Twenty Threes, and the TT. He did hear the Fives and loved them as well, and was impressed with the collection I played for him. I was taken by the difference in sound from each speaker too. He didn't make any offers to buy anything else, though he was looking for a CD player and Tape deck.
I set up the Twenty Threes in the same room the Fives are in as his apartment has a nice open floor plan and wanted him to get an idea of how they sound in a large room.

All that is missing is the L810, and you would have some kind of mutant Wilson.

I've thought about that. L810's would be sweet, and I have been watching for some locally. Something would have to go, they are decent size speakers.
 
See Glenn, you should have bought my tape deck at the fest. You could have flipped it for big $. ;)

What are the Angelicas? Sorry if it was explained earlier in the thread.

Hey Glenn, I know what you mean. It's really hard to let go of a good set of speakers. What would you part with for the
L 810's ?
