choose the best loading for professional woofer

[zedda]

those figures aren't real bad for half space - its 15.5" deep by 17.75" wide by 48" tall. Ask some of the guys real good with hornresp in the subwoofer forum to model some tapped horns and tapped TQWT-s for that B&C - if you already own then might put it to use - it looks like a high fidelity unit as a direct radiator.

here's an old thread at Speakerplans where I got the idea for the pipe and the aperture - look at the simulations - they should help you get an idea on how to use hornresp for this case.


Plan ! - D-20 (hz) Macro Sub ..tapped horn by moi. - Speakerplans.com Forums - Page 1

thank you freddi

is very compact

high fidelity unit naaaaaaaa
I am doubtful because until now these woofers have been disgusting...
I really hope that this woofer will suond better with these boxes

however, I want to do a test and throw 45 euro to build a test box...

I keep you informed

thanks to all

I do this test:
2.36 meters lenght Tline
if the box works I paint it and I will build the second.
otherwise transform the box in a tapped horn or other.

very destructive.... with 200watt the dishes in the sink begin to dance
drumming with the hands it seems too resonant ...
but when it starts to play you fall in love...
clean and deep bass...

incredible...

new photo!!!
This is the place where we will do aperitif this summer

Saturday I spent a day to pass a cable 3x10mm^2 (26m lenght) for powering the amplifiers
the cable is directly connected to the differential relay
from the relay to the main cable of 20mm^2 there is a cable of 6mm^2 (0.5m lenght)
the cable passes in a corrugated under tiles
I intercepted it in a well and I made a cassette with an industrial socket

Now the subwoofer has a sound much more clean and precise
Now the 12" mid-woofer are not keeping up with the subwoofer

.................Now the 12" mid-woofer are not keeping up with the subwoofer

A pair of 12" Mids can't keep up with a pair of 15" bass speakers ?

 

[simsons]

what are the dimensions for the box?.

truly incredible, the excursion becomes too much of the mid-woofer and amplifier goes into clipping frequently (only the led lights, the sound is normal)
evidently the sensitivity of the sub is too high
