Can the FP14000 run on 115VAC? How do you order from Sanway? What are most people running on the LMS 18 these days?
I can only comment on the FP14000 clone vs EP4000.
There is significantly
more usable power from the Sanway when powering an LMS. I had one ep4000 per driver for about a year, then moved to a single clone to power both LMS 18's (sealed, 4cubic ft each), and it is truly remarkable. I can't say I was ever displeased with the ep4000 - I just felt the drivers had much more to give so I went for the clone (which was always my goal... sometimes it takes a while to get around to it). I knew it would be louder when needed, and having one less amp in the stack is always nice. What I didn't actually foresee was:
1 - How much deeper the clone would go. It is unreal to watch the LMS cones hammering away at 5Hz and lower. The ep4000 was not even in the ballpark. It is so much more that a highpass filter is needed for driver protection, I use the mini dsp.
2 - Sound quality improving. In my fairly uneducated view it is from available peak power that the ep4000 did not have. Bottom line is no clipping the FP14k vs easily clipped ep4000. Sure you could
clip the clone with the LMS, but it is not common as far as I know. I also know there is more to sound quality improvements regarding the design and type of amplification the FP14k uses, but I am not in a position to make a fool of myself and try to impart those facts to you
3 - It actually makes me crave more. More drivers, more amps, more clean deep bass. It's hard to explain, but I feel it must be the effortless low distortion of the system. With the ep4000's I liked it... even loved it. I never really craved more though. I am wondering if I was picking up on distortion/anomalies brought on by beating on the ep4000's too hard and clipping them. Now that I am using the clone I feel I can tolerate and in fact enjoy more dB's of bass. Who would have thought an upgrade to the bass system which I was satisfied with has left me wanting even more of an upgrade... even though I am much more satisfied than I was...
This was all using a 15amp 110v power outlet. I have since moved and am in the process of setting things up again, now with a 20amp line. So far no difference has been noticed, but it has only been a day and I have no projector screen yet.
They can be ordered directly though the dealer, all info was very thoughtfully put in this thread
