I'M confused about the choice of CHR70's over the EL70's...and I've always loved paper. As many people in the FR forums have been talking about graphed performances and values but not much about the sound of their music, it's really tough to choose a good jazz/classical driver. I read a review of the "Tybone" speaker, called by Scott the Saburo and the Madison (Sachiko). Does anyone know which drivers were used in those reviews AudiogoN Reviews: Cardersound Tybone Speaker ?

Thanks! I made these out of MDF and simply did butt joints for everything. There doesn't appear to be any stress at the joints so they seem to be holding up just fine.I had never heard ANY single driver speaker before building these and since MDF is so cheap and easily milled/painted I chose to do my first build out of it. Now that I know I like the sound doing more exotic cabinets is next. I do want to do wood for my next build and want to do solid zebra wood sides with a black front baffle. Think that'd look good.

I don't listen to classical music so I can't state how these do with classical but I do listen to jazz and these are exceptional with jazz. I would highly recommend these drivers and enclosure if jazz is your music of choice. I've never heard any of the other MA drivers so I can't comment on the two you're looking at. Lots of people really like both though.

Ive never heard Sachiko or the Derwints or the drivers in question so I really can't comment. What are the Derwints? I wold love to put my 12's in a double mouth horn like Sachiko though!

Hey Skeeter, thanks for the info. I am encouraged about the 12's. Go to the Woden design LakeDistrict design series to see the Derwents (BVR). They are smaller, for the CSS EL 70's or CHR70 (Mark). Small pensils.

The zebra wood on the sides with Ebony front! Better have a really sharp router. They'd look super $$$$ and resonance would probably be low. If you made the Sachiko's with the 12's I think I'd love to drive to hear them! Probably others too.

I'm going to use baltic/Russian birch for the Derwents and then like you see how it goes for the next build. I am liking what I've read about the Fostex 126E in the Saburo and the 206E in the Sachiko's: The Spawn Family of Double Horns then read the reviews!! The owners are extatic.

Ok I found them, they weren't on Scott's site:http://www.creativesound.ca/pdf/Lake...aps-080909.pdf. They look cool.

Yeah I think the zebra wood would look cool. Pricey but all my others speakers are finely finished so they'd fit better. I dont think you can put the MA drivers in Sachiko as here designed for a totally different driver. I do want a double mouth horn though!

I'm sure your Derwents will look cool in that wood.

Hi Scott:
Can you tell me what thickness your MDF was that you used to build your cabinets?
I see in the plans for the Super Pensils that 3/4 inch plywood is recommended.
I have a bunch of 5/8 inch MDF, but I suspect that it probably should be thicker.
Thanks, Bill

Do keep in mind that 18mm (quality) ply has about the same stiffness as 1 1/4" MDF, so a double layer of MDF would meet that, but energy storage would be higher than the thinner ply.

Bill,

I responded to your PM but thought I would post it here as well. Definitely do use at least 3/4" if your using MDF. Panel resonances will be too high otherwise and definitely at least do the recommended holey bracing plus I'd add extra bracing up at the top as well. I used dowels cut to size and they worked well.
