I will stick to a sealed line array design but this time the ribbon tweeters will be monopoles instead.
I may or may not design a center speaker (with same drivers) that will suspend from the ceiling (on top of the screen) and point to the primary seating position.
8 x Aurum Cantus AC-130F1s. Carbon fiber / polypropylene composite. These drivers are wide bandwidth (7kHz) and have a very smooth midrange. There is a 2dB dip at around 4kHz but otherwise very flat. I find them very fitting for what I want. They will give me flexibility in Xover f point and slope.
6 x Aurum Cantus G3 Si. Silky smooth sounding ribbons with xover point at around 2.5kHz and up.
With the above driver combination I have the luxury to move the xover point by at least an octave.
I'll experiment in my room until i hit the sweet spot.
You can't do that with passive crossovers unless you have the patience of a camel and $$$$ of R L Cs laying around...
Active crossovers are unbeatable in that respect.
This is where I'm venturing into new ground: Class D amplification.
I'm planning to use Hypex UCD modules
for each tweeter and midwoofer line.
This is just at the beginning of my research so my plans may change multiple times...
I was originally planning to use some TPA3106D1s for each driver but the whole module design and power supply design would become exceedingly complex before long. I'd like to focus to speaker design and not amp design at this time.
Hmmmm... do I go the classic MDF route or do something really out there?
Internal volume is not that critical since I'll be crossing over at 80Hz anyway and the cabinets will be sealed.
I may do something crazy like a fiber glass enclosure with sound absorbing foam and stuffing.http://www.soundprooffoam.com/acoust...d%20Absorption
This is still up in the air and will be an interesting exercise in organic design.
Crossovers and Parametric equalization:
I intend to buy another DXC2496 but this one I'll fully modify before using.
These are my thoughts so far, I'll be posting more (with pics) as the project moves on.
