Well, after putting this new system together I will agree with you. Of course these little 13's(12's) can't play as loud or as deep as a LMS 5400 but the key is the design of the driver! I have had good drivers and they all did things well. The Danley's were designed for the 12-54hz region and excelled at it but the 50hz and above was hard to smooth out but was possible. My CHT subs can go deep with LT boost but were very sensitive in the midbass so they excelled at that(they did both but the midbass was more natural). These little guys are better down low than up top and one can easily feel the difference(with many of them). It is hard to explain but I can give a short experience that others can relate to. I have always run my subs hot for the added effects I got with them, always. My older eD 190v2 system I rab 12 dBs hot, my DTS-10's were 5 dBs hot, my F-20's were 10 dBs hot, my CHT subs were 12 dBs hot. The DTS-10's were the only subs I did not run as hot and I am thinking it was because they were tuned to 12hz and that extra low end gave me the feeling I craved so I did not need to turn it up as much. I kept cranking the other systems to get that feel. So, when I created an LT boost for my CHT subs guess what, I only needed to run them 5 dBs hot like the DTS-10's to get my desired effects. With these little guys, I calibrated them to 5 dB's hot and ran my normal scenes and I immediately ran to the processor to turn down the subs! I ended up running my new subs at 71 dBs or cold, not hot for the first time ever! This gave me the same effects as the DTS-10's subs at 5 dBs hot. I don't know how else to explain this but that is what happened so far. I am getting graphs and pics together to start a new thread and I still have not EQ'd my subs yet. I need to flatten them out a bit around the crossover region and they have a little peak at 20 and 40 hz. They extend to 5hz without any LT boost but drop off like a rock due to gear limitations, mostly the mic.
