Re: MiniByzy (Mini Byzantium) Build Thread

I guess the problem I have with all the isolation experiments is how do you really know what difference it makes. You would almost have to build one without to hear the difference.

Then I'll build a set without and we can all hear if there is a difference in Chicago(?) That'll be a fun experiment.;)

These will have no choice but to sound exceptional.

The power of science compels you!

outer baffles almost ready for paint.

You suck at interwebs ... fortunately, you sure put together a nice cabinet ;)

Speaking of, your inbox is full. ;) Just seeing if you got my last PM; don't want to be a bother.



On-T: Those cabs are really coming together. I can't wait to see the finished product. Another thing to aspire to.

Re: MiniByzy (Mini Byzantium) Build Thread

I'm sure we can. What I've found is the woofers need to be mounted to something solid for the energy to transfer to and dissipate from. Otherwise the energy stays in the driver frame. So that is were I came up with a sub structure to dissipate the energy and it is easier to decouple from the baffle then a driver. I'll send you picks when I take some. I'm also working on some very solid light weight cabinets that I think are going to help dissipate energy. I've done some sample pieces and have one cab almost built.
This is my first design trying to minimize vibration transfer. The woofer is pressed between MDF, and held in place by the heavy rubber on the Vifa. There's a very robust frame on this driver. The back of the "inner baffle" has Cascades' rubber/aluminum sheet plus their sprayed-on coating over that. The cab has the same layering inside, and a rubber gasket goes on the back of the "outer baffle" to seal and help isolate the exterior of the cab from the interior. It may just be wasted time,:eek: but I hope we end up with a good thing here. I think all the little benefits added up will make a noticeable difference. I hope we can sit back and listen to these experiments and make the next ones even better.

I'm sure these speakers will sound great. With Pete and Ryan working on them and you building the cabs how could they not sound great. I guess the problem I have with all the isolation experiments is how do you really know what difference it makes. You would almost have to build one without to hear the difference.

HA!!! I don't know how to "window" statements from other peoples comments, I guess. I tried to give a response to Dave Pellegrene.:o Sorry guys!

Risking sounding like a broken record, but the design and execution of this design is outstanding. Bravo to the designer, and the builder. These will have no choice but to sound exceptional.

Re: MiniByzy (Mini Byzantium) Build Thread

How are the baffles going to be attached? Sorry if it's been posted , I'm just curious.

EDIT: Nevermind , just picked up on it , inner baffles epoxied in place , outer baffles bolted to inner baffles.

Thanks Dave! I bet we could come up with something!

If nothing it's a lot of fun learning.

Re: MiniByzy (Mini Byzantium) Build Thread

Has anyone here tried to clamp drivers in place to reduce mechanical coupling to the cabs? How effective was it?

Yes, I've done several. Not sure if it really made much difference. From my experience so far any material that will hold the speaker in place has to be solid enough that it allows vibrations to get threw. To truly decouple them I've only found a couple of materials that will work. One is a thick layer of silicone. I'm working on a sub structure to mount the woofers to that I'm trying to suspend from the cabinet. So far I have one that seems to be working pretty well just haven't' had time to work on it lately with my ski season if full swing.

Here is a pic of one that I clamped in place with a rubber gasket to the baffle and rubber between the clamps. Not the best pic but the only one I can find that shows it.



Here is a pic that shows a constraint layer between the front and rear baffles. The clamp screws are only into the inner baffle. If you can find a flexible enough material to put between the driver and the baffle it would work pretty well. The rubber seems to transfer to much vibration. Something flexible like an 1/8 layer of silicone or a soft flexible rubber would work well.



Hope that gives you some ideas.
