I am not sure they want me listing their name and company title. That's for them to do (if they choose) Rest assured my friends have spent many a time listening to each others gear including mine, and also at shows.
Everyone has their own thoughts, and I was chiming in as I have a ton of experience on this topic and brand, and can give reccomendations based on my "own" experience and opinions. You can dismiss it or not.
Not many folks have tested each of those GE models I listed with the same equipment in the same space for hundreds of hours. I still love the brand and the house sound, just cant be convinced on the Trefs.
As for cheaply built, that is my opinion on all the Tritons, and dont mind it per se at the Triton 5 price point or a little higher, but I definetly REJECT it at $8500 for the references and a whopping 70% premium to the Triton ones. Also- the reference grill wasnt even seated properly in the tabs when I got the speaker, it was bowed out on one speaker from the factory and had to get a diagram sheet from GE to take off and put back on and screamed cheap parts when shined a flashlight and was up close with the drivers and parts. They do offer amazing customer service BTW and I have even spoken to Sandy during that time.
So to recap, overall love GE and the house sound, and think they over deliver bang for the buck for some models, but not at the higher price point. As per the orginal poster's question, I would say to stay with the 7s or 5s and use a serious sub.
