I've heard and been beguiled by Fujitsu Eclipse TD712z (http://www.eclipse-td.com/uk/products/td712zmk2/index.html) speakers at two Bristol Hi-Fi shows.

So when @daws0n put a pair of the smaller TD508 MKII (http://theartofsound.net/forum/showthread.php?53692-Eclipse-TD508-MKII-Nearfield-Full-Range-Single-Driver-Speakers) on sale recently I couldn't resist the opportunity of getting my hands on them.

To be honest, I was thinking I would either have them for a short while and then sell them on or perhaps have them replace the Heybrook HB1s I have in my home office. I wasn't expecting to be seriously considering having them replace my Spendor S3/5R2 speakers (https://www.stereophile.com/content/spendor-s35rsup2sup-loudspeaker).

When I first put them into my system, I was a little confused by the result. It didn't sound right. I listened to a few albums with them in place and then went to bed. The next day I put the Spendors back in, listened to some of the same albums again. Then I put the Eclipses in again, and they've stayed in place since.

Swapping between the two identified the difference between the two. And it's timing.

Both are small speakers, that concentrate on presenting a detailed uncoloured sound. Both have limited bass (I have a sub-woofer to add in more bass when I miss it too much :) ) So a lot is the same. If anything the Eclipses are slightly sharper at imaging.

So how does the timing differ between the two.

Well with the Spendors the music feels as a whole. The details of each instrument are clear and I can easily follow each through each piece of music, but the overall effect is that all the instruments are travelling together though the music. The results is lovely - The Spendors have given me hours of pleasure, and I fell in love with them the moment I heard them.

With the Eclipses it's like each instrument has its own line through the music. On initial listening, it's can sound wrong. But the more I listen, the more I like it.

If I was to summarise the difference between the two it's that the Spendors travel the sweetest path through the music, whereas the Eclipse produces a more warts and all presentation, which often (though not always) results in what sounds like a more real experience.

Currently, I'm thinking of keeping both sets of speakers and alternating them. I really can't decide which I most want to live with in the longer term. Eventually, I want to get bigger alternatives. I have been dreaming of getting some larger BBC style speakers (Larger Spendor classics, Harbeths or Grahams), but now I wonder whether the next speakers with be some Eclipse TD712z.

So in some ways the Eclipses have given me a problem - I now have more speakers than systems to connect them to. But its a good problem, and one I'm thoroughly enjoying having.

Interesting speaker. Uses a fibreglass full range driver. Not surprised it sounds a lot different to the Spendors.

Nice write up Rob, glad to hear you like them. I think you've described what makes them special - I too was a little sceptical of their presentation for a while, but once you adjust to their presentation their qualities shine through. I did wonder how much of their speed and fluidity can be attributed to single full range drivers in general, or with the speaker suspension / enclosure design... This video is really worth a watch:

Now I have put a set of traditional 2-ways in their place the sound muddy and boomy in comparison - I do rather miss the beautiful mid-range and will be looking out for a set of bigger eclipses also!

It's a shame they are somewhat of a niche product as they produce sound like no other speaker I have heard... I believe their "time domain" theory is patented, I wonder how many other designers would use it if opportunity allowed?

I fancied these as well for my study system as an alternative to my little Tannoy DC6's but did the measurements and wasn't sure they'd fit in the small space I have in there. I've enjoyed them at shows where the clarity - which exists without shrillness that often passes for clarity in 'high end' setups (ribbon tweeters and solid state amps can give this effect - ugh) - has always impressed.

A less substantial presentation to my normal Tannoys (of whatever size), these aim to satisfy the ears rather than engage the whole body. But there's a definite place for them I think. Like the new Hecos in the Pure Sound trade thread, this is a modern take on single driver that finds technological ways to avoid the compromises in older single driver designs. Highly commendable.

Thanks for the link Dawson. Very interesting.

I've been so smitten by the Eclipse sound that I've now tracked down and purchased a pair of the 12" Eclipse TD512. So if you're interested in trying some TD508 there may be a pair up for sale shortly - along with a pair of Spendor S3/5R2

supposed to be excellent speakers.

Ah nice congrats :) Let us know what they are like in comparison please? I still have my wee td307s hooked up to the tv, they are great for dramas etc where human voice is at forefront. Not so much for big action movies but really shine at 100hz and above.

Interesting that he just wibbles on about box vibration in that video, given that, on appearances, the box is shaped to mitigate edge diffraction.

Reggie, are they very directional (does the sound change much as you move your head about)? Or do they have quite a wide sweet spot?

ReggieB

I haven't noticed any need to be in a sweet spot.

Personally I found them best up close and tilted to ear height. They are not fussy with regards to room boundaries so can be placed near a wall. I've read that the larger models need more breathing space.

Interesting, I find that whilst point source speakers give great image they tend to have a smaller sweet spot than multi-driver arrangements - maybe the lack of baffle aids this here?

Hmm not sure that's universal. Certainly applies to Quad 63s. Not at all to any Tannoy I could mention.

Yes. I agree.

Fair enough, there's always more speakers to hear!

I know they're not 'real' tannoys but the 609s I had were pretty location specific.

The TD512 speakers have arrived! They are significantly bigger than the TD508s:

The extra size makes an obvious improvement at the bottom end. I don't think I'll need to turn on my sub-woofer very often.

Initial listening and the clarity and natural sound is just wonderful. At the moment, I've got them on my existing stands. I need to get hold of some spikes before I can get them in place.

One very obvious thing about these speaker is how well they are made. Really solid and beautifully put together.

Considering the drivers are only 4 cms extra those cabs are much bigger than I expected!

I was a little surprised when the boxes arrived. It's silly really as I've seen the TD712z often enough, so I should have realised just how big they'd be.

Their black colour suits my system better than white - and my wife likes the look of them - so management approval!

The stands are very tall. They don't look that substantial, but looks are deceiving. The top and bottom plates are solid aluminium, and the central tube is full of acoustic sand - so very solid and well made. I need some cones to sit them on before I can use them in place on my wooden floor.

For now, the speakers seem to be fine on my current stands.

I'll get my Isotek system disc out over the weekend and have a play with positioning.

I use spiked stands on a wooden floor also. Try granite chopping boards underneath them to protect the floor. It's a cheap fix and makes them easy to move about when sat on the slabs.

I've put the TD508s up for sale (http://theartofsound.net/forum/showthread.php?54659-Fujitsu-Eclipse-TB508-II-Speakers). Very tempted to keep them, but I don't think I'd use them now I have the 512s
