My New Line Array--It's a Modified CBT24
The sensitivity of CBT24 is only 87 dB. However, it looses much less dB per meter compared to a traditional speaker. With 3 m distance the loss with a CBT is 5 dB, whereas it's 9,5 dB with a regular loudspeaker.

Without room gain, 50W will play about 102,6 dB at 3 meters (9.8'). With 200W and same distance, you'll reach approximately 108,6 dB (still without room gain).

For each speaker, right? That's pretty loud trough the midrange.
The 50 watt rating is at 8 ohm and these arrays are wired at 4 ohm...
With that output it would be giving the pair of 10" subs a challenge to keep up, unless they have a pretty long throw.

Makes sense for the 2.5" drivers

My current 50 watts receiver is more than enough for the arrays as is. As Omholt and wesayso point out the arrays have virtually no volume fall off in the room akin to near field line array characteristics.

Once the 1200 watts matching powered subs are finished, I can use the 125 watts per channel vintage Yamaha R9 receiver that powers the 10" passive subs in the photos for the arrays. Power will not be lacking.

Hmmm, my Pioneer VSX D812 is going through thermal shutdown with my array. I guess I'm the one with issues.

Great looking speakers. How are you applying EQ?
