MTM with TC9fd

[lordglum]

Prototype boxes mocked up.
Parts on order.

Version 2. I like the ported box with half open baffle.

 

[adason]

some of you were badmouthing me about ugly speakers with unfinished back I am building so I decided to put back grill (3d printed) on three bookshelf speakers and repainted some
remember, I am only using these from 150 Hz up, in biamp system, so I do not need them to go lower than ~100Hz
I like open back free from reflections, that's why...

How do you acheive that sizzled bubbly burnt skin creature from the La Brea Tar Pits look anyhow?

Good idea on hexagonal grill 3D printed backs. Minimal fiament for those.

 

[boswald]

I don't know, Ed.
I think I like them better unclothed and 'in your face'.

 

[adason]

no worries, plenty of speakers like that around here

you mean this surface?

 

[xrk971]

Yes - blistered frog skin, for lack of a better description.

I think the official name for such a texture is "toad skin bumps," at least according to a Google image search I did.

That texture is used brilliantly to enhance the gestalt experience of listening to adason's speakers -- you don't even need holographic imaging or life-like sounds to give you the chill-down-the-spine experience. Just looking at the finish of the speakers would give you goosebumps already.

 

[xrk971]

I wasn’t very far off. Toad skin not frog skin.

 

[ewollowe]

I think the texture is kind of lunar looking?

 

[xrk971]

Good one - pock marked with craters.

Adason still hasn't revealed the secret of how he makes this finish.

 

[adason]

its a neat trick I do with gorilla glue
no secret, just very hard to describe

 

[lordglum]

One step closer

Man these tiny boxes turned out to be a pain for something so small.

 

[xrk971]

They look nice though - but they are not MTM?

 

[lordglum]

Thanks for the compliment.
They are not mtm. I moved the tweeter purely for looks with the front port.
They do sound better with offset tweeter and MTM but I am happy how they sound as is.

xrk971,

do you think 10F/8424 would be a direct swap for tc9fd in your version (with 2nd order filter phase coherent) ?
