Amiga or Helix? Push me off this fence

I am looking to start my living room entertainment project after weeks of lurking. My use will be in a 23'x11'x8' living room, centered at 9' on the 23' length, couch is against a wall of windows, 4' opening to the front door and a hallway 5' away from the edge of my tv stand. 60% tv/movies 40% music.

I want to start with a LCR set and cannot decide between Amiga/sunflower or the diysg Helix MT l/r and MTM center. I'd greatly appreciate a push in one direction or the other by the more knowledgeable.
 
What is the Sunflower kit?

Amiga Amiga MT Tower Speaker Kit with Knock-Down Cabinet
7" alu woofer / 1" soft dome, crossed at 2 kHz

Helix Denovo Audio Helix Dome MT
7" woofer, unknown material / 1.1" soft dome, unknown crossover frequency

If I had to buy a kit, I would like to have more information than given on the the DIY Sound Group Helix webpage. Other than that, MTM centres are a bad idea as they have a terrible horizontal off-axis dispersion. A 7" woofer will not do for home theatre, so you will need a separate subwoofer. Then the LCR speakers only have to work down to 80 Hz, so they can have smaller woofers than 7" for better dispersion.

I recently built a pair of Amigas for music and HT duties and have been immensely impressed. Great full range sound and strong bass all the way down to the mid-30’s, which meant I disconnected my wireless Klipsch sub and just stick with the Amigas.

Assembly was straightforward and they only needed 10 hours of break-in before they really came alive. The parts express kit has almost everything you need to build them except screws, binding posts, glue and polyfill for the bottom 20% of the cabinet.

Highly recommended - can’t go wrong.
