I've read some issues with the CSiA6 being very power hungry, so wondering if my receiver would adequately power this...
Also, that CSiA6 I note is very huge, especially depth wise, so if crossing a sub around 80-90hz, does the extra low end of the CSiA6 compared to the A4 really come into play? Obvisouly the CSiA4 is more easily to fit, so just would love to hear people's opinions. Thanks!
The CsiA4 and A6 each have their own advantages and disadvantages. Also attempts to match driver sizes between the center and mains/surrounds doesn't always make sense. I've run the Csi3(A4) and Csi5(A6) with every Rti speaker up and down the line, including the Rti6's (A3's) and Rti4's (A1), up to the A5, A7 and A9's. At the height of my Rti phase, I was running a smaller system in the family room (for TV and casual music) consisting of RtiA3 mains, a Csi3 center and Rti4 surrounds. Everything worked together well. For HT I had A9 mains, A6 center and A7 surorunds, with Rti6 rears. Again, they all got along together very well.
The Csi3(A4) has a sealed back and given its smaller size is easy to place in a video cabinet where venting is not an issue. Conversely, the Csi5(A6) is HUGE and HEAVY. The rear ports confound the best made plans to house the beast. Yet the sound quality is amazing. Where the Csi3 sounds fine for female voices, the larger A6 center really delivers on male voices and "beefy" audio demands, such as strings. The difference is notable. In direct comparison, the Csi3 sounds somewhat weak, especially for HT duty.
One might think that the Csi3(A4) might blend well with the RtiA9. After all, they all depend upon twin 5" drivers. But again, the smaller center is easily overpowered. I once tried using a third RtiA9 as a center. Disappointing. The CsiA6 still sounded better. I have also tried Csi3's standing on end as rear surrounds. Again, too weak. The beefier Rti6 made far better surrounds. Similarly, the Fxi4's sound fine in surround position on some lesser material (like TV), but the larger (and bulkier) FxiA6 handle theater duty far better.
So much comes down to 1) the size of the room you need to fill, and 2) the type of material the speakers are expected to handle. The smaller speakers have the advantage of easy placement and being unobtrusive, but for heavy duty theater use (exploding helicopters) you can't beat big towers.
