Finished mini speaker with TB W4-1337SD - Page 2

domtw · 29th December 2010, 07:58 AM

Hello,
Sorry, I haven't seen these posts before today.
Those speakers are now 12000km away from me but I will try to find the notes I have about the correction network and the sketchup file for those interested...

I am very interested ... I have a whole bunch of exactly these drivers here and I want to use them to make small satellite speakers for rear channels in 7.1 surround.
12000km wow

Thanks in advance for your help.

How is the off-axis response? I am considering them for 7.1 dipole surrounds.

Dipole?
These speakers aren't dipole you know.
To make them dipole you'd very probably need a complete redesign of baffle and crossover, right?

You could put two of the cabinets next to each other, facing 90 degrees away from each other, wired out of phase.

Worked for the surround sound I use (admittedly, the drivers are different, but the spaciousness of the sound is pretty impressive).

You mean like the typical little Bose speakers?
I'm afraid you'll need to find another term to describe those than "dipole" as the term "dipole" already has a meaning when it comes to speakers.
A "dipole" speaker doesn't have an enclosure and radiates sound to thze front and to the back simultaneously.

No, that's an Open Baffle. There's no rule that a dipole has to have no enclosure.
What it does however mean is that you have to radiate sound to the front and the back, with inverse phase.

If the speaker radiates sound out the front and the back in the same phase, it's a Bipole.

And those are an artifact of when the surround decoders were really bad.

If you are thinking of a dipole as a surround speaker, forget it. They are an HT artifact worse than the sideways MTM for centre.

I've never liked the double satellite speakers either but what exactly do you mean by "sideways MTM centre", Dave?

Bump.
DomTW? you still here?
