They are his mum’s old speakers. She is 102. I kid you not. It’s her Consonance amp for sale also. She upgraded her whole system. 

The eclipse are reference with the lead and felt lining. 

Great speakers.

My setup. Monuments with Elite crossover upgrade.    

Here they are with the first layer of sealer applied:       To see them beside what I would consider 'normal' sized floor standers really shows the scale of them!

More progress pictures - the veneer looks like it should be a great visual match for my rack 😍

The foam on the midrange in my Epitome went yesterday so they are off to Atilla to be refoamed. This should give them another 15 years. 

Expect some wear on the older drivers and as @gat474 mentioned you cannot get these drivers anymore so expect repairs when getting on 10+ years.

The midrange in Osborn speakers using Focal drivers doesn’t have a high pass so they get all the bottom end, must have been running them hard @jakeyb77!

15 year old foam. Not hard really at all. 

If they aren’t crossed over then that’s a serious design flaw. Why would you run all all the signal into that into a 7” driver when you have 4 x 10” bass drivers? 

@aussievintage had the same issue. 

Maybe they aren’t the speakers for me 😳

It isn't a mid-range speaker in the 3 way speaker sense. These are classed as 2.5 way speakers aren't they?

Yes. It's just age. Mine did well to live 17 years. foam should be here in a week Will post pictures of repair if I am successful in fixing them.

Yeah to be fair the foam peeled off like tissue paper. It was well due for change on mine.

While I wait for my new foam surrounds to be delivered, I didn't want to keep using the old drivers in case they damaged themselves, so I did this.   I removed them to prep for the fix, and put in these cheap Jaycar Response brand drivers (about $35 ea from memory) that I had in another set of tower speakers. They have similar specs, just a bit less efficient than the Focals. They fit in a way that doesn't damage the OSborns, and the screw holes will not be visible when the original drivers are put back.  You can see the alan key screws I put pack around the outside so I wouldn't lose them.

 

The sound isn't so bad, it's quite acceptable in fact.  Certainly has enabled me to keep listening.

Bidding has started on the Eclipse. I had to kick it off. Why not. 

Interesting mod there @aussievintage

I have two spare NS-1000 mids that seem to slot right in. Maybe I should try it. 🤔

I get my Tannoys back tomorrow so I’ll probably just use them

If I screw up the Focals, I could even live with these until I get something better.

I’ve been looking at drivers with the same footprint and better specs. If you can find the 7W2 it’s rated at higher wattage. But also too hard to find. 

Your purchase price helps also compared to mine. 😳😝

Real enjoyed the eclipse when I heard them years ago, really sweet and nicely balanced.

But they go lack the authority of their bigger siblings.

The  highs are very "sweet" - it's the same word I used.    The subwoofer digs in for some fairly tight bass when playing some acoustic double bass in jazz, and orchestral stuff.    Not sure about authority.  Have to listen to my brother's Epitome towers a bit more :)

Today I started to prep one of the Focals for re-foaming.  Just thought I'd post a few pics

 

This is one of the drivers.  You can just make out the cracks in the foam where it is ready to fail. (about 8 oclock)

 

DSC_0285.jpg.d351a8d88576b64331d4f7433f41941f.jpg

 

Firstly I scraped the outer edge with a small screw driver.  You can see the thin foam is a gooey mess, partly disintegrating and partly turning to glue.

 

DSC_0283.jpg.aad3bdd7627bdfca5d5ffac9d0b84a0e.jpg

 

Here's the driver after carefully removing the rubbery mess from the edge of the cone.  The cone material is called Neoglass by focal. It feels and bends like thin plastic.  Feels more robust than I thought. (good :) )  I need to find out what will remove the gluey remains, maybe alcohol, maybe one of those citrus oil based removers.

I’d use isopropyl on the baskets. Not sure about the Polyglass cone though 

I used De-solve-it then isoprop.       Found the best tool for cleaning the edge of the cone was my fingernail.  I'd spray a bit of cleaner on it, use my fingertip to spread it along the edge, then with the fingers of my other hand supporting the cone edge, I'd scrape the top with my fingernail.

Semantics.    It's "right" to call it the "midrange" seeing as it handles from 200hz (or wherever) up to the tweeter.

But that's not the case according to the post to which I was replying.  They were saying it handled everything from the bottom end up, because the crossover (at 125Hz btw) did not include a high pass filter for it.

 

I don't know if that's true, but that was why I ventured that it was 2.5 way and the speaker was really the woofer of the 2 way part of the system.

Ahh...  I see.   It's still right to call it the "midrange driver".....  or the "bass/mid".

It doesn't include an electrical high pass filter .... but the driver and the box themselves act as high pass filters  ;)

Depends on how you want to use the terminology.

 

2.5 usually refers to two identical woofers, where on has a low pass filter.    eg. two woofers which play from 40 to 1400Hz ....but one has a low pass filter stopping it from playing above 200Hz.

 

Here, it's really just a mid/bass driver, which doesn't have/need an electrical high pass filter.

Speakers packed up with paper and shimmed.  By raising the cone, the surround will sit nicely into the cone for gluing the inside edge.  Probably don't need to shim yet, but I did it anyway.

 

DSC_0291.jpg.33ad30afa4273a1371bde9bd3cdccbf6.jpg

 

Gluing using a small bottle of glue I bought with the surrounds. I suspect it's just normal PVA white glue.

 

DSC_0292.jpg.dcf04e573210ee3c40356feaae37e051.jpg

 

Both surrounds glued to the cones, but sitting raised above the outer edge while they dry.  I used the cotton bud to stroke along the edge to seat the foam edge to the cone properly.

I was hoping to just let the shims give me enough clearance all round.  They are a firm fit (just cut from an old record sleeve)

Has anyone compared the Eclipse towers to the Epitome towers? 

Also, anyone compared the Epitome Towers standard with the Reference?

I have heard the new Epitome Reference towers at my brother's place, but only for about half an hour.  I plan to visit for a longer listening session.  How to compare with the older Eclipse Reference (non-tower) that I have now?  

 

Bigger and better springs to mind.  Very big and heavy to move about.  The bass sort of fooled me.  On one record I thought it sounded a bit light, but on the next the bass blew me away.  I would say it's a case of not introducing any false bass if the recording is lacking, but making it shine if it is there.  I guess that's what is nice about having that extra subwoofer in the tower version.

 

The high-end is harder to compare, as it's a very different tweeter to mine which have the early focal tweeter that you can't get any more (that some say was a very special tweeter).   Overall they are highly detailed and very resolving of individual sounds.

There is also 20kgs of lead inside that help to stop any resonance. Although if you see inside the cabinets you’d wonder if there would be any cabinet resonance anyway. 

I was asked not to take a photo of the cabinets inside which is fair enough.

Thanks Aussie, good to hear your thoughts.  Yeah I've heard the Epitome towers a few times before, but only the old tweeters.  I won't get too caught up in the finite differences between models, so may look closely at the standard towers vs the reference and elite.  Maybe even the eclipse towers because they're still a fantastic speaker, but saving some money.  I doubt I'll spend on the Elite upgrade...

 

 

@Quark what towers do you have?  I remember listening to those and loved them...

Very true, well worth the extra $$$ though for the lead lining, IMHO.

I've got the Eclipse reference towers. No longer running the Stereoknight valve pre and mono blocs - I've gone with an Elektra Pnyx pre and HD300 amp.

That's very interesting.  I loved them, maybe a better price point for me.

Both versions I have heard were lead lined.   You can barely feel a vibration on the outside when they are working.

Being a longtime fan of the Elektra combo myself, just wondering what sonic changes you experienced going to the Pnyx HD combo from the Stereonight?

It's been a bit of a journey Joz. With the Eclipse towers and their beryllium tweeters I found the sound too bright initially when moving to the Pnyx. I've since changed out the crap Electroharmonix valves for some NOS ones and am much happier with the sound now. The NOS valves also have a much, much lower noise floor. The Stereoknight Enigma was also a little bright for my tastes until I swapped out the Electroharmonix valves for NOS ones.

 

I know Arthur reckons he built the Pnyx to suit the Electroharmonix sound, but I've always found them harsh sounding, noisy and unreliable junk.

thats the great thing about valve s can just change out like that to find a better fit.

 

@joz no harm in rolling some in to see what think.. can always change them back out if not really your thing :D

In case anyone's wondering, I'm running :

Valvo PCC88 7DJ8 in the rear sockets (these are a 7V heater)

Siemens A-Frame  ECC88 in the front sockets

 

Running the Valvos in the front sockets was way too dull.

My Eclipse Reference have the same tweeter, but I run all sorts of valves, especially 12AX7s in my various phono preamps. In one I have an Electroharmonix in first position, then a Mullard (original, not one of those new copies).  In another I have two Electroharmonix.  In a third, I just discovered, I have an unknown thing in first position.  Must have left it there last time I was trying out spares - looks like a Ruby of all things, followed by an Electroharmonix.    In my line preamp I have two lovely AWV 12AU7s.

 

Haven't found the sound to be overly bright on any of those combos.  Maybe they work better in phono preamps.

Job finished  AND successful.    Glued the outer edges of the foam down yesterday, and installed them this morning.  Working like new!!

Great job!  Are the new surrounds co trolling the extension better?
