BIB for Fe206e

gunnet · 13th September 2007, 01:43 PM

Hello, I want to build the BIB for the 206e.
The internal dimension are:

25cm width, 219,2cm height, 34,9 depth. They are right?

I already have a 203x25 MDF panel that I use for paint, could I use it for internal baffle. For the rest of the enclosure I could use a nicer wood, but mdf is cheaper.

thank you

Looks OK to me.

MDF should do OK for the internal & rear baffle (chipboard would probably be better though). Birch ply for the rest.

oh I forgot, 2,9 meter height of the ceiling is enough to use the BIB?

I have near 4 meters of 4mm ofc copper cable to connect the speaker. So I will use near 2 meters for BIB, is Ok for the sound?

thank you

Should be fine. What amp are you using?

harman kardon 675, I have alsto the t-amp, if it sound good I could use one t-amp for channel

You might want to add a resistor to the wire (about 3 - 3.5ohms), or shift to a thinner, higher resistance wire with your HK SS amp, or the bass will be a bit weak.

So I could use thin cable for external connection to amplifier, while using the 4mm for internal connection. OK?

Of course. Or you could just use thin wire for both. Thin cable for speakers has its own issues (such as the clipping of transients when current demands are high) but these are outweighed by actually having some bass.

As I say, an alternative is to add a small resistor in series with the driver. I prefer resistive wire though as it's two less connections per side (connections have caused more problems than wire ever has IMHO), and a ceramic won't actually behave in quite the same way as resistive cable.

Assuming these are internal dimensions…

The box volume: ~191 L

GM’s formula suggests: Vb = 20*Vas*Qts^1.25

For 206E: Vb=20*54.53*(0.18)^1.25=127.8 L

Seems like a significant difference.

It's almost impossible to have too large a cabinet. You can always damp down what you don't need.
