Thank you all.
I finally bought d' sub. And surprise, surpise, I ended up with JBL e250p.
Klipsch model were nowhere near as musical and so does Paradigm model. I wasn't able to try Definitive Tech since it run out of stock and the store is not a dealer of that brand anymore so no more definitive tech for a while.
In my humble setup, I manage to tinker the JBL e250p to add just the right bass, seamless and transparent to my front. I normally listen to stereo mode without a sub (before i sold my old sub of course) since my old sub just cant cut it. But with the e250p, it added depth and weight, subtle and never overbearing, just the way I like it. Its like its never there, but turn the sub off and you will definitely notice the changes. I have listened mostly to jazz and some light rock, maybe the muddiness that most have observed on this model is on some type of music that is very fast and dynamic, that I need to try later.
As for movie, its awesome. Just tame the volume knob otherwise it becomes boomy. I did notice that it does not seem to go very low. maybe just 28hz, not 25hz. At 25hz, its almost inaudible to be totally useless. I'm not complaining since I already noticed this at the store after 3 hours of auditioning X 2 visits.
Comparing with MK and Velodyne models I heard, this model bites the dust, but i'm not willing to pork out X 2 to 3 of what I paid for the JBL.
Again, thank you all and till next time. As for me, I'm getting ready to rumble, prime time.
Cheers.
