Ligne Ceramique, 3-way TL with Accuton/ Eton

[Jan Deckers]

Hi,

nearly finished my 3-way TL with accuton/ eton drivers. All is playing loud and clear in my room.
On my homepage there is more to be seen.

Suggestions always welcome (on the woodwork?)

Regards,

Jan

Nice work, Jan. I built several TL style speakers in the 70's, they were a lot of fun, but driver selection for extended bass (as opposed to merely well damped bass) was a bit of a challenge; it seemed like higher Qts parts usually worked best, whereas the drivers I liked with higher sensitivity were overdamped.

Nice web site, too. My German is rusty, but my Dutch is non-existent - ;^)

How did you do your measurements? You're crossing over the C79 fairly low on the top end, which is probably a good thing, as they're not the easiest mid driver to work with.



Any plans for veneering and finishing the cabinets?


Best regards,

Jon

Hi Jon,

well, the veneering will come in a few weeks. First I wait for the MDF to "work"a bit. I think I'll take walnut, or some "Burl" veneer.
The graphik isn't really a measurement but a simulation with Speaker Workshop. I still have to measure the speaker (but still need to buy a microfone). Well, Il will translate the page soon in english because there are a lot people who can't speak dutch. As for now, the speakers are playing great. Lot's of detail and so on.

Regards,

Jan

Are two Dutch forums not enough . Still a great looking speaker, does me remind of those speakers of A.O.S. (German DIY ScanSpeak distributor).

Are those graphs, traces of the plots provided by the manufacturer? Also I can't detect any phase information. I would suggest some notches on those Eton woofers, in my experience with it's smaller brother (7" Hex), those units has some nasty resonance peaks.

Cute kids. The little girl almost looks like she's wearing a hakama.

As for what to finish the speakers in? I love walnut, but I was actually going to suggest differently. I'm assuming (the mother of all screwups) that this is the room and location where the speakers will be used? If that's the case, I was thinking something like a mappa burl would look nice in contrast to that wood floor that you have. Looks (from the color and what I can see) a lot like a Mahogany or Jatoba or something similar.

[Jan Deckers]

Love walnut too. and the mappa burl also (thanks for the link).
The floor is merbau, als a darker (little bit red) wood.

Chris, thanks for the link. That is one fantastic site! :T

You're welcome David. I wish I could take more credit, but all I did was point the way.

Jan, good job, and as Ten99 said, cute kids! One of my veneer samples is Mappa Burl and I really like it. Caution: burls have a very "busy" pattern, and on a large surface, may be TOO busy/distracting. They would make nice-looking bookshelf cabinets however.
Here's a woodworker's suggestion for something really exotic: Waterfall (quilted) Bubinga accents on Padauk. Very complimentary. I haven't worked with it yet, but waterfall Bubinga is supposedly strong, like maple.

Kids? What kids? I thought that was the construction crew ...:wink:

[Jan Deckers]

Well,

the cute kids can be sometimes very ...... exhausting :M , but they are a perfect crew/ :P :P
I love that veneer-page, and must say that bubinga (waterfall) is a very nice veneer. Only problem is maybe where to buy it.
