Default Apogee Bass ringing

Here the deal.... the resion i got out of the Apogees was the bass ringing...after hearing the ringing, i heard it every time so i move on back to the ESLs...An have used A ribbions out of the Magnepans with the Acoustats....but after seeing the bass set up in these... thay have dealt with the ringing....with the rubber???
The more i look the more i wont....If you have not seen the Apogees....
The bass metel went under the wood....this made them ring....Now we no what thay did ....it all about the LOOK....well that was then $$ 5k for this look.

Double sided tape is a great idea it is quite sticky and should hold well I would think.


tyu, I know exactly what you mean,I haven't really noticed the ringing as much as the fact that my Duette's have lost their tension and now the sound like a rattling pie pan! He,he

If I do get to the point of messing with them I will try to save the original diagphrams and incorperate the rubbber band surround as well.
I am not impartial to their originality but rather make them sound good again as I love my DIY ESL's.

It is quite amazing the true cost of that $1,000,000 sound !!!

had apogee stages a few years ago, but power handling was a joke an you needed an arc welder to make them sing,they eventually blew the output stage on my amp, so went off ribbon speakers. i have made the mistake of thinking all these type of speakers were like that, not so! have had a few speakers since avantgarde uno,anthony gallo 3.1,various diy ones but i must eat humble pie these epsilons are a different class in fact i am shocked at how much better they are, really. notes start so much cleaner no overhang and power handling is in a different league to apogees,dynamics are astounding ,example fleetwood mac dreams mick fleetwoods cybal that he hits at the intro to this track is delivered with no compression at all and its not untill you here it reproduced properly you realise 99% of speakers fail in this task i dont think its possible for a conventional loudspeaker to do this, my uno horns were supposed to be dynamic not in comparison to these there not !

the thinner cpc tape would increase the sensitivity as the total weight of the diaphragm is important the lower the better! I have just started using 6um mylar with my 4.5 mm aluminium tape on my latest rebuilds. Although the thinner mylar makes it a bit more delicate to work with. I notice that the magnets are spaced, I have my magnets touching each other. This gives a stronger field and louder sound. All my speakers have 4,8, and 16 ohm inputs so you can drive them with any amp. I don't use any crossovers, which only waste power. I have built speakers ranging in size from 60 x 40 mm to 7' 2' in size, using ferrite and neo magnets, and I am still learning. I have many ferrite magnets left, so I will be busy for a while yet. I may even rebuild all my rebuilds as I learn more, wish me luck.!!!

63 magnets of that size, you could use more of a smaller size about a pound each? Cheaper than buying a new one and very easy to replace the tape although I would do it as a continuous length myself. and would get rid of the gap between the magnets!They look even more primitive than my designs underneath!!If you place the magnets touching you can use tape of half the width. This would increase the sensitivity.

Default Shame, shame!

In my experience, all the Analysis speakers do things no other panel can: however, they don't last forever. I've just had my Omegas and Omicrons repaneled in Greece because there's no-one in the UK (that I know of) who can do it.

We were hoping to resell them, but without the local backup, I'm a bit cagey about doing that, and I'm letting stock go at a loss. The shame of it is that nothing else sounds the same!

It's a shame the design isn't put into larger scale production. They're like Apogees and Maggies and Quads with all the problems fixed. Good luck with the double-side tape!

hi, yep the double tape is only temporary as all the rubber suspension is rotting away even in its present condition its the best sound i have ever had and i am afraid to say i have had more speakers over the years than i care to remember,once i get a suitable type of rubber i can effect a repair i only have to cut out the rubber from the diaphram as the panel itself is fine,none of this is rocket science just needs time and a bit of research. 3K to get a factory repair is beyond my budget and i believe i can repair them to a satisfactory level,the general layout and soldering of components leaves a lot to be desired so i will sort that out as well .time and a bit of lateral thinking and i believe these can be improved over the factory build as it looks like they were built in a hurry something i am not constrained by, i hope the current analysis speakers are built better my ones may have been early ones so they may have inproved quality control by now its quite amazing they sound so good in there present condition

Brian,

I used to own one of the first Analysis Omicron produced for about 10 years. I went through one set of ribbons during this time. It did not cost me so much, as far as I can remember. Have you tried to contact the manufacturer himself? (Mr Hartzis)
If I still had a speaker like like this, I would have liked to be in original condition.
