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
