MTM with TC9fd

Prototype boxes mocked up.
Parts on order.

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

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) ?
