Acapella ion tweeters

We are a dealer for the Acapella line here in Colorado U.S.A. The tweeters are indeed available separately (at least in this country. I am surprised it is different in your country Detlof). They are $6,900 USD a pair (though the Euro/dollar conversion fluctuates a lot these days). They can be connected to your system using standard RCA connectors. They come intheir own separate, attractive and mountable enclosure. They do not have any ozone problems.

They are very, very good and they will improve any speaker out there (except other Acapella speakers, of course, which already have the tweeter :-).

We are at: www.audiofederation.com. There is another dealer in Texas and another in California (both U.S.) and one in Toronto (Canada). I do not know if there are any in Asia.

The California dealer has some really cool pictures of the tweeter here on Audiogon at: http://cgi.audiogon.com/cgi-bin/cl.pl?spkrfull&1036312491

Enjoy!

Detlof: What kind of equipment are you using with those tweeter ( Preamp, speaker and amp.) Do you know if these tweeter are wideband ( like the 54 Khz Tannoy) Do you think that those tweeter would be great with JMlab mini-utopia and a REL strata sub ?

Thanks for the reply

Sean, only read about the Ionovac, never heard one alas.

Travis, they have a built in amp and Acapella uses them without external amplification. The user has to fine tune the tweeters to the rest of the system which is a cinch. 2.5k would indeed be a steal, but audition them first. They need an overhaul every 4-5 years or so with normal use.

Justacoder, Switzerland is tiny, less population than greater NYC. There is only one importer and a very small market and I had to twist his arm very hard to get my pair. He of course wants to sell complete Acapella systems.

Dysmalonyx, I have a separate amplification chain for them in my system, consisting of a Spectral DMC 20 Mark I preamp and a pair of ancient Spectral DMA 50s switched for mono, all wired with the apropriate MIT cabling. This makes for an excellent match. I decided for this setup, because it gave me the advantage to really fine tune for every bit of software that I play. This is especially important with SACD. The tweeters are very wideband, go far into bat territory, like the Tannoy you mention and through them you can easily discern that something is strangely amiss with SACD in the highest spectrum of the soundfield, (apart from the hiss, which with some discs is really a bitch) some strange sort of constriction, difficult for me to describe, which redbook CD's do not have....and yes, they will go with any kind of speaker. I placed them at ear level, with their opening aimed at the point of my nose, so to speak, to get the best results. That's at least what sounded and blended best with my wall of stators, putting them at the outside, at each end, right next to the walls and aimed at ye old red nose. The effect is amazing, not only the pristine and complete effortless rendering of the high end, but the improvement in the soundstage, both in width and depth, as well as instrument placements therein. These tweeters pick up so many subtle cues, which simply were not there before, that you simply have a tremdous increase in threedimensionality. But be warned, once you have heard them, it is difficult to listen to music without them. Things become unbearably veiled....and they are so fast, they merge effortlessly with the stators. Cheers,

The ion tweeter has been around for many years. The plasmatronics was the first I became familiar with from the late 60's or early seventies. There were environmential questions and also the problems of heat and maintainence. Can't comment on todays models other than hearing them for the last 4 years in europe before the importer brought them to Canada. Is there service in the U.S or does it go back to Canada?

At an audio show years ago John Dahlquist demo-ed a system with Ionovac tweeters. Sounded very cool and open .The hotel room was also cool with the windows open to exhaust the ozone buildup..
