Why is the ECS-10 so expensive. At $849 are we supposed to expect it to outperform the other LFM subs or is it price high because it fills a niche... because of its size. I need to get one or two subs when I purchase some LCR's. I do like their size because it would make them disappear in a room. I'm tired of large equipment. I would love to hear from anyone who has experience with this sub.
