Hi Guys,
I was planning to build Troel's 18W ()
Flat panel and crossover V2 sealed.
I know Troels explicitly writes that have to go ported because of the high Q, and I'd say that's right, but I suppose a sub could solve the issue.
They will be on the wall beside the TV (Stands are not an option) so the reduced bass may be a good thing.
Madisons suggests 6l sealed F3 100hz and it could work as midbass with dedicated 10" woofer, but directly to a sub seems too high.
Winisd gives me a Q of 7.07 at 12.5l and this is the max space I can spare, so that could work.
What size would work better in your opinion? (conected to AVR, No proper DSP) should I aim at a slightly higher Q?

Thanks!

I would suggest to make that cabinet vented (Fb=50Hz; 2" by 6" port) at 12.5 lit, or as large as you can to be able to use its bass capabilities if you should ever need these as a stand alone setup. Stuffing ports makes them sealed and ready to be used together with a sub. Q being 7 is not something I would worry about. It is just a sum of 3 different losses.
It makes sense for versatility, but I'd prefer to optimize it for closed box and eventually redo the box if I have to go vented. Also because I'd put the vent on the front and any plug will be visible...
To build it and use it vented in 12liters is still a possibility, not sure I really need it crossing to a sub and if not I'd rather have a slightly smaller optimized box.

Scanspeak recommend 13.5 litres, i doubt you will be able to hear a difference if you must go with 12.5 litres.
Give them two or three weeks for your ear to adjust to how sealed bass sounds and I am sure you will be happy.
