The Sanway did 15kW at dual 2-ohm of the 14k it was supposed to do.
The XBS 22k did 18kW.
The 22k blew up on NotNyt at 4-ohm near the 8 to 18kW mark.
I would stay away from the XBS 14k, it is questionable.
I would recommend the 20k over the 22k as it is more robust, double the transistors of the 22k in the area that blew up on NotNyt (probably there for a reason me thinks!)
The Smiths did a bit less burst, but more RMS than the Sanway.
If I understand the test results correctly, the XBS has more RMS than the Smiths, because of having 2 power supplies instead of just 1, but not officially 2-ohm stable. Although I run 1 of my 20k's at quad 2-ohm and it is doing just fine thus-far.
Will be testing my 4 XBS 10k's this weekend, although only at 8-ohm and low power, as I need all 16 channels to stay working...
The SpeakerPower amps cost about 8x the price of the 20k for comparable power at 4-ohm.
Two SP2-12000 vs 20k etc, but the SpeakerPower is quieter and more power at 1-2ohm.
The SP2-12000 also requires two 240V breakers.
No risk though.
I think 8 20k's would smoke it pretty good in terms of channel count for the same price.
Higher risk of DOA or failures, but they will send you parts for self-repair, or you can paypal it back to them.
Whatever makes you happiest...
