I am closing the beautiful road to the perfect clone of the Sibelius for myself and am posting the final dimensions including damping material.
Can you summarize what are the differences between your project and the previous one posted by @Hondasnl ? A note about the impact of each type of the damping material as well as its amount on the sound would be very helpful to fine tune other individual projects too.
 
Hi qbas, I have determined the dimensions very precisely by means of many photographs of the original Sibelius. Furthermore, the measurements show that after application of a measured amount of damping material, the Voight pipe is exactly tuned to the 10.2 driver.
 
Hi!
Yer, I just watched the Sterephile YouTube from Axpona…
Harley seems to get good reviews.. probably the first time for a lot of Americans to hear his speakers..( they are not easily available to listen to in Australia 🇦🇺 either)

Have any of you DIY guys had a chance to listen to them, and are they much better than your diy speakers?

I see his price has gone up to $9000 USD… ouch 😓!
 
hi Wil_NL!
Great work and great result! And thanks for sharing your design and details!
Have you had the opportunity to hear if there is a difference in sound between the Birch ply and solid Oak boxes?
I’m guessing that as the material is so thick, that the difference is minimal?

Hi JohnnyDee, a friend has build the Sibelius with birch ply and there is no difference in sound. the point is simply that the cabinet itself is dead.

@wafflesomd, the Sibelius is made of solid oak planks of A-quality, without knots and such. They leave these in their workshop for a long time to prevent warping. then they are made by hand under miter to a super tight cabinet. That may cost a bit! This year the price has been increased, because they want to enter the American market and spend a lot on promotion. and the Sibelius sounds better than super expensive speakers (with lots of drivers and expensive filter component) that cost many times as much!
