Looks amazing.

Are you using vacuum infusion when making lamellas ?

No I am not using infusion to make these laminates. I am just using a vacuum and a proper technique for the lay-up and post process. I really like the matt Finnish in these that matches the mbl look. This is due to using frekote as a release agent. This One I feel is pretty close to mbl quality I still need to work on a couple of things that if I decide to make another It will be simply for the purpose of making a perfect mbl quality driver. All others will be made for experimenting to achieve better than this control measurement.

It looks great, and the care in making and assembling is very evident in both the descriptions and photographs. I would not be surprised if at the end you end up out mbl'ing MBL..

Thank you guys for the kind words. I would have never thought you guys would say the things you have to a wannabe MBL builder so it means a lot. No commercial benefits so far, maybe in the future. Any ideas what you guys would want? Let me tell you guys, this speaker is very challenging to build.

This is the first speaker with no audible voice coil rub and buzz from any distance just clean sound a landmark which any builder of this speaker can be proud of. I will post videos later. Measurements will be done later when I get the stand made.

Default Recording

Here is the recording hosted on sound cloud. Recording doesn't do it justice I think omnis are hard to capture as they sound different from room to mic. adjust volume as mic position changes.

Yes. I would want enough parts made to assemble two myself!

Full plans (after all it's diyaudio) with comments ? ;-)
Ready made parts (such as lamellas, metal parts) ?
Full kits ? Partial kits ?
All of the above ?

On the other note, if you're going to make bass driver, do you plan to use thicker carbon fiber for lamellas or aluminium as on original MBL (it's probably next to impossible to diy them) ?
