bass speaker help

[tinitus]

and it works

I will call it The Antiressonator 😀

many years ago, Hi-Fi magazine had construction plans for a CONCRETE woofer cabinet. it was an effort to eliminate resonances from the cabinet materials....

... it was an effort to eliminate resonances from the cabinet materials....

good point 😉

built a crappy proto, and now being punished with this rework job

front is sorted, and decided to look at the cabinet back
first step, to make the woofer hole slightly bigger, and improve edge shape

big heavy woofer, and I wanted to support the chassis, taking some load off the screws

working inside a limited space, new circle router tool needed
and then some work with file and sandpaper 😱😀

 

[tinitus]

just to let you know I'm still alive, my new and final bass project 😀

Now that looks like a woofer.
Phwoar.

Get a 6" driver to cover the mids (>500Hz) and you'll have a killer system there. You could probably get away without, but I like the extra "twang" you can get from a decent mid.

Chris

was my plan
but next step might be a mini-dsp 😉

found 4 pieces of 30mm MDF on my attic
with some additional improvising, it fits nicely

Looks like a tight squeeze - will this be open backed, sealed or ported?

Pictures/sound clips please 🙂

[QUOTE=chris661;2911718 open backed, sealed or ported?


sealed 😉 about 55liter brutto, minus 10liter(driver) = 35-45liter netto

 

[tinitus]

and it goes like this, layer by layer 4x 9mm 😛

 

[chris661]

Wahey, looks like that ought to do the job.

More pictures please!

 

[tinitus]

that was quite tough

 

[chris661]

I'm liking the lines.

Made any noises yet?

 

[tinitus]

getting closer

 

[tinitus]

need to consider speaker cable connector
noticed a speakon which also accept a 1/4" jack
but I dont know much about this

btw, theres a really nasty ressonance when talking into cabinet
but if inserting a small bucket into the hole, it disappears
which also ought to happen with the woofer mounted

need to work on front baffle design now

 

[tinitus]

despite 40mm thickness, the rather big backplate appeared a bit too ressonant
bracing added

front baffle design is more or less sorted

Nice build !

 

[tinitus]

thanks
going to paint it black now
and sure hope its playing soon
my guess is sometime in the weekend

bullocks, forgot I need speaker wire connectors

 

[lduarte1973]

that looks so nice in wood color why not just varnish ?
