    Posted: 21 February 2017 at 2:39pm
Hi Guys.
I am working on a "SONOS-Killer" project, and have come to the subwoofer part of the project. I have 2 pcs 8 inch units for the job. Is there any chance there is a plan for a compact enclosure, ported, bandpass or the like that will fit my project?
All suggestions are welcome! Clap
Just remember that the "wife factor"Cry is in play, so "the smaller the better"! 
(I know it poses dificulties getting bass from a small cabinet, but isn't the life all about finding solutions?)Wink

Oh, got it... Had to delete the "%20"...
That's a lot of text...Cry Was hoping for a more specific concrete suggestion for an enclosure

Watch out for drivers with really high Qts values of 0.6 or above, these would require such a big box to work correctly that in normal size boxes you don�t get much low end. They are better of being used on the rear parcel shelf of your car, where they can enjoy a massive rear chamber

Hi padde.

I'm a novice here too so here's what I had to learn:

Either there is a plan for that driver, or you can build your own or mod an existing plan to suit.

If you want to build a cabinet specific to that driver the best thing to do is download a programme called winISD.

Google how to input the ts parameters.

Open two or three projects in winISD and mess about with the box size and tuning frequency until you get an idea what looks good.

Then come back and once people see you're serious they'll help you make sure your cone excursion and vent mach are ok.
