Summary: I wasn't sure what to expect from this device. I have a Vizio sound bar, but needed something with a little more oomph. All I did was combine this beauty with the soundbar and it really made a huge difference.
Summary: I had and older JBL speaker system and gradually changed out the components. I changed the subwoofer the same time as the center speaker (JBL ES25C) and love both pieces. The subwoofer is a little more powerful than my older system, move stylish and the cross-over works better.
Summary: Purchase 2 in 11-2014 for an apartment's main combo dining/living/kitchen/halls---about 600 sq. ft.. I was very nervous about getting these. I wanted front firing 10 inch sub-woofers. These had the JBL reputation of flat response.
Summary: The sub woofer has power and can does what it needs to do. That said it works for a month then just dies and then you cant get commercial work done under warranty anywhere. I called jbl and they gave me a number that hasn't been doing work for them in 10 years.
Excerpt: I bought this subwoofer because mine new subwoofer that i bought in july 2014, it's not good. It make a very strong noise, and I can't use it. I bring this subwoofer to Brasil, and nobody,could help me wich it!
Summary: This is a very musical sub and digs relatively deep(about 24-25hz in room). I use it in a studio and its not flubby sounding at all, I can easily hear bass notes and transients that are lost on most cheapo subs.
Summary: The sub was awesome for the week that it worked. From the first play it started giving off a weird burning rubber smell and within a week it was dead. Never turned it up past half, or did anything that would lead to it burning out, it just decided it didn't want to work anymore.
