Some of you have a lot of sound knowledge, so here goes...
I am renovating my house (hence no electronics projects lately) and I would like to fit self made speakers flush with the double ceiling while I am at it.
My idea is use the two “speaker out” at the rear of the TV. No amplification.
The vertical void space is about 7cm, 10cm max driver depth, the space between joists 60cm.
The ceiling is plasterboard, 18mm OSB, 70mm void, concrete.
As for the intended use, TV and radio while cooking. So no HiFi pretensions.
I was thinking of a single full range driver per speaker, of the kind teen drivers retrofit in their rustbuckets.
Any ideas on the driver size, speaker volume, port or batten to make this sound no worse than a car door would be appreciated! No need to go too much in detail!
