The 950 was an original design developed by Outlaw with Eastech (the manufacturer) that Eastech later made "clones" of for several other companies (Sherbourn, Atlantic Tech, and Fosgate - although Fosgate's FAP-T1 had some modifications such as a front LCD monitor that made it very hard to recognize as a 950 clone).

As I understand, the multichannel amps are designed by Outlaw and the amp manufacturer specifically for Outlaw (they are also made in the US). I'm not sure of the exact lineage of the M200/M2200, but I know there's at least one other company (NHT?) selling an amp that is cousin to the M200/M2200. The RR2150 was developed by Outlaw from scratch, as was the ICBM-1. The LFM-1 and LFM-2 are a design partnership between Outlaw and Hsu. The LFM-1/LFM-2 are not the same as the Hsu STF-3/STF-1 subs - different port configurations (Outlaw moved the ports to the bottom), different amp on the LFM-1, and different cabinet style/finish - but they are somewhat related.
