Speakers with the most detailed midrange? (non-ESL/planar)

@woofer72

Not sure what you had in your old SCM 100 - there have been several tweeters over the years. The old Excel millennium tweeter was excellent - one of the best. The older vifa tweeter was sibilant but my quite old pair of SCM 100 may have lost ferrofluid (it dries out after a few years hard use with any tweeter). Not sure about the even older Audax...

The newest tweeter just integrates perfectly. It has no ferrofluid. I no longer think about a tweeter in a separate way like you would do with other two ways or three way speakers. It just sounds like sound even if your eyes know there are three drivers there ...the sound is just completely integrated.

I guess the tweeter was the last thing they eventually had to build in house to get the kind of quality they require. I find it surprising they could do better than Excel Millennium. I think it took ATC about 10 years to develop so it just shows you how very good Excel/SEAS products are!

Would like to upgrade to the new tweeter for the 150's. Have a version of it in the new ATC 12 and like it a lot (desk top system). Though of course not listening at the same SPL.... The Excel tweeter you are talking about is that the SEAS tweeter I got or is it a much older tweeter?

I actully use two ATC c1 subs to the Lipinski's. Functions very well, but again they are near-field and not sure designed for very high SPL's like the ATC. ATC subs are very musical and plays the bass lines very clean. No distortion to hear. Using them with the Lip's makes a very fine full-range system. The Lip's works best I think as a closed monitor crossovered around 60-70 Hz. The C6 Sub is on my list but expensive also used and not sure I need it. You sell me yours Shadorne :-)

I have the older yellow one's. Actually I got three (one read). 

Will hurry up the A/B test :-)

Have a look at the new XTZ Divine Delta speakers. Using Accuton and Mundorf. Nice price. Think I will try these. I bought their new Edge amp recently and am very satisfied with it. Cheap fine power. Sorry, no SALKs around here.

Shouldn't say this....... but will probably invest in some Infinity Kappa 9 soon. I mean they are legends. Also heard them in a store some time ago and thought the mids and tops were beautiful and very life-like and also worth a lot - you could stand up to them.

Why not some (new?) music to crank up your systems:

yes, son of Willie..

ATC EL150A...wow!

@gosta

Yes the Excel line is SEAS premium line. It has a copper ring waveguide - so rather unmistakeable. Used in Linkwitz Orion and by Joseph Audio. It is a very expensive unit costing more than most high end speaker woofers/mid range and 5 to 10 times what most dome tweeters cost - probably why it is so rarely used - most people have never heard it.

I'm not sure which tweeters were in my SCM100 either. They were a late 90s edition (home version), that the previous owner upgraded to SL spec. I don't believe he ever upgraded the tweeters. Thanks for the info on the tweeters. I knew about the Vifa tweeters, but did not know about the Excel tweeters. I'm guessing mine had the Vifa. I'd really like to hear the ATC tweeters. They surely do not release anything until it is as close to perfect as possible. 

I forgot to respond to your comment regarding the SL woofers. I agree that they are amazing and they contribute to a clearer midrange. When A/B comparing the bottom end on the ATC to Dynaudio, I found that I could hear the actual tone of a kick drum in addition to the punch. The Dyns would only reproduce the fundament punch, without the tone. I felt like I was sitting behind a drum kit and was able to hear the decay of the resonant side drum head. Truly amazing.
