Need advice or guidance on full range drivers.

this is the sound bar system Dave referred to in earlier post

the enclosure volumes for the front row 3 were the same as for the separate rear surrounds - quite a delightful sounding little system for a small HT room

woofers are dual SDX70 per enclosure - the whole system was designed for wall mounting via Z-clips

I can get the A6 into 2.5 litre (what we used, 3 uMar-Ken6). The 5.2 can be squeezed into 1.5 litre

Fantastic, my initial box modeling for SBB4 alignment generated a default Vb of 3.3L, so I did try some custom values in the range of 2.5-2.8 and it still looked very similar to the book values, so it's great to hear that it's been confirmed in practice (seems it's not always the case). Looking closer, 2.5L could have better step response and group delay (at 80Hz) than 3.3L 😉

Very nice! Many thanks to you and Dave for your input and feedback, it's very much appreciated. I'll post photo's and measurement data once I complete my project. Not a slam dunk that my 1.5 concept will hit the mark...
