Many have upgraded the crossover's on the Adagio to good effect. Many sell them, because the stock x-over's are garbage! Very veiled still after long burn in. I could just dump them. However, I am selling some bookshelf Speakers an my old Gen Genre II's today at Midwest Spkr. I am inquiring about new x-overs, crossover points, an Clarity and/or Mundorf caps with Erse foil inductors seems to be the way to go on these.

So, these have become my new project! Midwest will do the work...I can't solder. The Adagio's have a wonderful transmission line and great driver's. I think it will be worth the effort! Other accounts of the upgrades ability to produce clarity can't be rubbish.

Meanwhile, my Vintage Polk SDA1's in stereo are kickin' it well. I have a pair of ERRx coming by the end of April too! I look forward to placing them all over the Room-Radial's baby....~Radial's.

Then the Adagio's after rebuild...........and burn in!  Got's to have toys....an more than one pair of Speaker's to rotate through the Listening Room!

The Adagio's are in the Shop getting Mundorf mcap supremes. Joe will work his magic. Probably crossed somewhere between 5 an 8K. I'm calling it the MG944/ERRx mod Supreme! Veiled no more I tell ya!

My Custom Adagio's are done! I pick them up today and will have them in tonight. Party on Wayne......party on Garth.

PM me your number and I will send you pic's:
-of the incredible crap that came out of these Speakers (x-over's)
-and the Mundorf Mcap Supremes that went in.

Acoustic Zen Adagio's:
great fit and finish = yes
great Transmission Line design = YES!
quality underhung made in Germany woofers = yes
quality tweeters made in house in CA, by Mr. Lee = yes
X-over's?  AH.....no!
Even Mr. Lee stated in a thread....they could use an upgrade.

I have them running full range on the woofers. Crossed at 4.5 kHz with the Mundorf's.

SOUND?  I've had them hooked up for an hour now. Whahoooooooooooooooooooooooooo! .....and the Caps are new obviously. Musical Musical MUsiiiiiiiicalllllllllllllllllllll!

You bet Lon. I have Bob sending my ERRx's with Mundorf Mcap Supremes too. Have a great weekend.

I'm now off to take pictures of my daughter for the grand March/Prom. Another one of my babies is all grown up pretty much. She starts college at St. Thomas University in the Fall. Beautiful 65 degree sunny day as well. We deserve it.

Stone...it's awesome that these speakers worked out for you.  I have never heard the Adagio's in person, but the overall design seems very similar to the 944's, which I think are an awesome match with the ZMA.  

The transmission line is special and I think an underutilized design (probably because it is more complicated than building a ported box).  I feel like I can hear "ported" bass from a mile away, and it doesn't resonate with me.  I can't recall the last time I heard a ported speaker I really liked.  Other speaker standouts for me are Volti, Magico, Pure Audio Project, Scaena, Acoustic Zen (all non-ported designs).

Also, I have always liked ribbon microphones for capturing detail and nuance when recording instruments.  I guess I like ribbons in speakers too.  I have always liked Magnepan speakers (well, many of their attributes anyway).

No one said you couldn't buy a set of speakers and tear the crossovers out.  Just like no one said you couldn't buy a car, tear out the lame V6, drop in a V8 (and cut an exhaust pipe back).

Sleepers are more fun anyway...and this forum knows that all too well!  

Enjoy the music!

Stone...I wonder if you are thinking about the 945's vs. the 944's.  See specs for the 944's below:

94 dB with 1 watt at 1 meter
28Hz ~ 22kHz
4 ohm nominal impedance
Driver compliment - MTM
Crossover - none on woofers / 6dB on tweeters
Size 10" wide, 16" deep, 42" high
Solid 1.5" thick cherry baffle
75 lbs ea.

Stone…I wasn’t implying anything, but that doesn’t mean that I’m not delusional.  :o

Stone, I didn't take any offense.  I didn't read the entire post, but it seemed to me you were talking about a speaker that was much smaller than the 944's based on your description (dwarf, 78 lbs).  

I have no doubt the Adagios are great speakers.   I have heard the Crescendos on multiple occasions and they are fantastic.  I spoke with Robert on the phone about the differences between the Crescendos/Adagios, and he would only recommend the Crescendos if you had a large room (25 ft long min) and could get the speakers 7 ft from the front wall.  

Otherwise, it's Adagios all the way.  I'm not sure how much better, if at all, the crossover is in the Crescendos (vs. Adagios), but they are at a very different price point.  Anyway, sounds like you are very happy with the speakers/mod, so Enjoy!

Hi Wiaudiophile,

Welcome to the forum!  Great speakers from Stone of Tones descriptions.  What are you pairing the speakers with?

Steve

I would also love more info. If anyone has got the cap value and wiring scheme from stone, I would love to see them.

I had a pair of these paired with a Torri VCap years ago. I sold both and worked in the industry for years. Always missed the combo and just picked up a new pair. I'd love to increase the clarity a touch. I love the speakers and they are also sentimental to me as my wife and I listened to them for hours every night for the first year we were together. She fully supported me getting another pair once I found a set come up. Any help would be appreciated!

Hi Adrian....this is what I had done to them. WTW config (as you know). I looked over at these (now sold) Parker Speakers and said ahaaaaa! The rest is history.......... enjoying the Adagio's single capped since March 31, 2015.

Top notch Tube Amps only with this config. SS can't do it/cut the mustard.

Glad you have a pair again. You know how good they are............. .

stone_of_tone

Yes 2.2 MCap Supremes. No problems. I've been tempted to change the caps ...but, nope....if it ain't broke.......don't.

My Zen Select SE84CS was not enough for them. However, a Rachel on up should be fine. Go Torii.

Ubet, you're welcome.

Great thread over there Dominick/Err. I've been tempted by MiFlex going back 2-3 years ago, now. The Mundorf MCap Supremes stay. Just to pleased with them to try the Mi's.
