Nice built there! Is the brax exvibration the same stuff as the alfa blue from alfatec?

And i like those front speakers!

I know they are good, but look so creepy! Like somebody had too much aluminum foil layin arround!

then the external folder I have dealt more with isolmant (polyethylene foam closed-cell crosslinked physically)

with the same material had been isolated from the roof

Good job! I love Alfa 147's!

Post by **ttocs** » Thu Aug 13, 2009 7:38 am

I think I might have done the sound damping a little different and put the exvibration pro on first and then the sheets. Never seen it done like that.

Post by **Bfowler** » Thu Aug 13, 2009 9:47 am

did you make those distribution blocks yourself?

the whole install is awesome!

dwnrodeo · Post by **dwnrodeo** » Thu Aug 13, 2009 10:59 am

Excellent install! I'd be a little nervous about that distribution block being unprotected though. Don't want anything shorting out.

Misfire · Post by **Misfire** » Thu Aug 13, 2009 3:05 pm

Very nice work. Did I miss the sub??

qwerty · Post by **qwerty** » Thu Aug 13, 2009 3:43 pm

Thanks all.

All this work it' handmade by myself (and in same point isn't good

)

@Misfire: Hum, at the moment thw sub it's in this position

(sometimes I need to remove it)

@Bfowler: Yes the distribution block it's made with the help of my friend that have an CNC machine.

@joerg & ttocs: The structure it's

1 layer of Butyflex T250/AL link to the datasheet (sorry only on ITA)
2 -3 layer Brax eXvibration Pro

4 layer (only on external folder) Isolmant similar at the Vinyl product.
