I do believe the PL-200 is an excellent sub as I have one ( and another arriving monday or tues) esp. if you take in the amount of $269! Just to be fair thou as you had posted thr quote of the Axiom not going as low as the PL... (in which I do believe that as I'll explain it below) but the Axioum's are better matched with thier line of speakers as they tend to be for music rather than HT.
Just going off what I have experianced within the past few months...
As comming from an older Onkyo HTIB ( HT-SR800 set up... since replaced now) my first purchase for a sub was the PL-200 and LOVED it ( still do by the way). I was able to compare the older sub to the PL as there was no contest at all! I always read "muddy" in reviews but never quite herd or understood it untill I was able to compare. Once I was able to compare TEHN I realized what they ment as the older Onkyo sub sounded "muddy". Of corse a quick note here, I can make the PL sound a bit muddy and boomy if I set it up incorrectly or place it to close to the wall as I found out at first ( works best at least 12" from the wall BTW) buy not as bad as the Onkyo sounded. I never realized it produced that sound until I was able to compare the PL to it.
Since owning the PL-200 I was in the "mood" to add another sub to my system in the back portion of my room to equal the bass out. Not that I really needed to add another sub as the PL-200 does VERY well all by itself ( as my wife would say "good lord, the whole house is shaking!
) but in all respect "its a guy thing" I told her as I love action movies and I want to be "into" the movie when thier is "action" I guess.
So when I was about to get another PL-200 it was out of stock ( quite a while actually) as I came across an Outlaw LFM-1 used for sale so I purchased it for a good price. When I first introduced the LFM-1 to the system the two subs did not work good at all as I would say "they didnt get along very nicely". After about a wekk of trying differnt postions, setting and etc. I was able to get the setup to work out pretty good, not perfect but to where it worked well.
As I was able to compare the Outlaw to the PL I was able to pick out the differnace in sound, not a drastic differance as the PL vs the Onkyo by no means but to where I could tell/feel it per say. The Outlaw seemed to have a more balanced bass or should I say "smooth" as compared to the PL but not to the point that would make the PL sound bad just a differnt puch is all. I do realize there is a differnace between the two such as rms, porting & size goes. The PL has 250 as to the Outlaw has 350, the Outlaw has a downfiring dual port and is a little larger cabinet to where the PL has a single rear port and front firing... I just thought I would point this out in case some where not aware of the Outlaw subwoofer.
The outlaw did sound a bit tighter with music then the PL but the PL excelled in the HT department. I still believe the PL sounds great with music btw but I give the edge to Outlaw on the music department. I am selling the Outlaw to a good friend for what I paid for it as I am getting the PL to replace it. Dont get me wrong here, I do believe the Outlaw is a fantastic sub that is without a doubt but if I were to look at buying a new sub ( as in someone looking to replace what they have that is ) it would be hard to justify spending the extra cash for the Outlaw LFM-1 plus ( newest model to replace the LFM-1) since the Outlaw is $549 to where the PL can be had for as low as $270 ( as I am writting this that is ).
I do also realize that everyone has thier own opinions to which I say " thats excellent" as to they should! Some value thier SVS, HSU, EPIC's, Outlaws and so on ( the list can get LONG here) and I think thats great as I do believe they are all an excellent line as well, it's just a bit harder for me to justify the extra money for what I know works well for me.
The main reason I am replacing the Outlaw is only for these facts:
1) The PL has a smaller cabinet and looks so much better then the Outlaw as the PL has a very nice piano black gloss finish to it as the Outlaw has the flat black. Since I have this sub in the open ( cant hide it due to the layout ) it looks much better to acomadate the surroundings ( as the wife would agree )
2) I was able to get back what I paid for the Outlaw and save a few dollars ($100 in fact). The Outlaw sub was 3-4yrs old to where the PL is brand new.
Just as a reminder...
This is my experiance with what I have done within the past couple months. By no means am I trying to "down play" any other line (esp. the Outlaw ) and this is just my opinion. I feel the PL has performed excellent for my situation!
