JBL E250P and 'I, Robot' (1 Viewer)

[Kenneth Harden]

Chapter 18 - the one where the USR vehicals are in the tunnel (don't want to give away anything, being vauge)

My sub was in the corner, X-over set to ~90 Hz. and gain at about half way up (or is that half-way down ) - wood framed house with open crawl space. Room is large (15 X 30 X 9) and open to kitchen and beyond, so no chance to really 'load' the room like in a small, sealed bedroom. I was about 12' away from the sub.

Anyway, I have been spending a lot of time around a lot of hi-end subs (REL's, Def Tech SuperCube's, M&K's, etc.) and I have to say, for what I paid for this JBL (well under $200) it absolutly BLEW ME AWAY.

Bass was totally and utterly clean. It went very deep and this was at some very high levels. The louder explosions gave the good ol' shake the floor and compress your lungs, but there was no boom or distortion. Just like the $2,000 REL I played the same scene on in a SMALLER sealed room.

Listening to this sub at a place like Best Buy or CC does it no justice.

Compared to stuff costing MUCH more, this thing is incredible. I cannot imagine what a large SVS must be like - but I also cannot get a SVS for under $200

Ken,

I have the E150, always wished that I'd spent the extra $40 or so on the E250, but it's pretty adequate for my needs especially with movies even in a much bigger room (probably around 600 sp. ft. all told with 15' ceilings).

Tell me, what do you have the back settings on:

LFE or Normal?
180 or 0 Phase?

I couldn't really make heads or tails of what the manual says about those settings, have no idea what in the world they actually mean.

 

[Kenneth Harden]

LFE will play whatever the RCA cables send to the sub (probably up to 200Hz. or whatever the highest frequency output is) where normal will let you set the crossover on the back of the sub.

I have mine set to normal and the crossover is set to about 90 Hz.

The phase control is used to set the phase of the sub. 0-degrees if it is in the front, 180-degrees if it is in the back of you - but you can play with it to see what works.

I have it set to 0, or I guess that means set to 'off' or 'nothing' or 'no change'

Not to make you feel bad, but preformance aside, pull the grill off the 150 and 250 and compare the woofers - looks like a big difference, but it might add up to a moderate at best preformance gain. If you got the sub from where I think you did, you got a good deal. Enjoy. You can always sell it and upgrade!

I had to have some warranty service done because it would not go into standby mode. Rainbow electronics in Sacramento, CA did an awesome job fixing it.

Sheesh, JBL ought to pay you to write their manuals!

Does your receiver have a subwoofer crossover setting? I have mine set for 100Hz since I have tiny bookshelf speakers, so "LFE" it is.

Yeah, the 250 is a 12" woofer and the 150 is 10"---but the 250 has an extra 100wpc which I think makes a significant difference, esp. in the cavernous 500 sq.ft. living room I'm in. Good thing I don't watch too many action films or listen to rap music, I use my sub more for fill-in bass.

Well, it sounds like you might've paid about the same that I did for the better model: $167 shipped. Sigh!

> You can always sell it and upgrade!

Yup, in a year or two after I buy some decent tower speakers, I might just go for something in the $400-500 sub range like SVS or Hsu.

I knew when I saw this movie in the theater that it was going to give subs a good workout. Tried to pick it up last night, but it was sold out.

Very nice DTS track.
