CrazyBlue,

Don't you ever sleep? Just because I am awake, it doesn't mean you should stay up too. I am organizing the Subwoofer review threads.

I like the idea of the separate sub manufacturer threads. This will be very helpful for those like me who are stuck and do not know which sub to go with. The most difficult part of my decision is that I can't find a place to audition most of the subwoofers that I am interested in.

Anyway, I hope to see someone who owns a DSW Pro series and another person who owns a DSW Micropro series post in here and share their thoughts.

So to the owners of Polk Subs and to those that own other subs, what are your thoughts on this? Should I take advantage of the price drop? Would it be a good value for performance?

My room is small and either a 10" sub or a dual 8" would work out great.

Default Couldn't wait for my "weekend" PSW125 polyfill project.

Edited after some corrective measures:

I couldn't wait, so I did it tonight. I bought two 16-ounce bags of polyfill and carefully added about 2/3 one of the bags to my Polk Audio PSW125. I bought two bags because they were only $2.47 for each bag (Walmart).

I have always enjoyed my PSW125, and now I enjoy it little more, with a detectably smoother, more "settled" response, and without a doubt it has to do with a reduction in enclosure coloration. I also added a little less than 1/8 of a turn of gain on the sub's volume control dial.

However, today, when I was able to turn up the volume appreciably, I noticed the very lowest response of the sub was clearly missing. I figured that, although I didn't pack the enclosure tightly with polyfill, I still added too much, and it was affecting port conduction. I removed all of the fill, returning the equivalent of about ¼ of a single 16-ounce bag. I was glad for the downward-firing port, which allowed the neat placing of the polyfill on the exposed MDF floor of the enclosure.

My lowest response was restored, and I feel that I am still benefitting from the polyfill treatment of my PSW125!


Like CB, I also took photos to document the process (love doing that). The initial addition of polyfill was rather easy to do and was completely done in less than 15 minutes. My removal and replacement process took about five minutes.

Interestingly, I added polyfill to my Polk Audio CSi25 center channel as well, and it's interesting how the response of the speaker has changed - again for the better.

I've been wanting to upgrade to a CS20 center channel speaker, and am waiting for a good deal on one. In the meantime, my CSi25 is not a bad center channel, but at times the dialogue sounded a touch "boxy." I used my Pioneer Elite SC-05's 9-band channel equalizer to compensate for the spike in the low-mid range, where the occasional "boxiness" occurs, but it's hard to escape enclosure-related resonance problems completely.

Adding the polyfill to my CSi25 has essentially eliminated that phenomenon. It hasn't transformed it into the perfect center channel, but it most definitely moved it up a few solid notches.

I still won't be dissuaded from upgrading to that CS20 when a sale is ripe, though!

Thanks again to CB and BD for all the inspiration and accurate information!

Rob, do think the "boxiness" sound you were getting from your center was more to blame on the cabinet or it's location? I ask because DonRSD put some pollyfill in his CS1 to get rid of the same thing in his center due to it being located within an enclosed part of his entertainment center. I see your entertainment center is quite open as mine is, so I wasn't considering doing this because my center being in the "open". However, if you think it had more to due with the quality of the center and not with the location of the center channel, then perhaps I will reconsider and add some pollyfill to my center.

I added some Polyfill to my Onkyo center channel when I was hearing some port chuffing in my living room and noticed a pretty big difference overall in sound with it. You should all do it.

Driver_King, you just stuffed the port right? Or did you actually take it apart?

Forsberg,

Thanks for your input.

Indeed, the build-quality of my CSi25 is the culprit. It has always been a touch "boxy" on certain low, male vocals (Tommy Lee Jones is a good example). There is some sort of low-mid resonance which comes up on occasion, and although few people would notice, I do.

I have kept my center on both the top of an entertainment center (from my setup a few years ago) to where it is now. It has always had its curious resonation. Again, it's not bad by any means, but a noticeable mark of the CSi25's limit of quality.

As you have alluded, I would say that an unconstrained location for a center channel is the best way to situate it. I have mine pushed very far ward to thwart potential cavity-resonance coloration.

I looked at DonRSD's gallery, and yes, the baffle of his CS2 does seem to be back a bit far. Even that little bit of distance tucked in can create cavity resonances - likely more noticeable at off-axis listening locations. I would suggest bringing the front baffle of his CS2 at least even with the front of the cabinet. Maybe even further out if possible - even if by only a half-inch. If his center channel resonance-issues are caused by it sitting too far back, then the polyfill won't help, as the cause of the audio coloration is not inherent to the speaker itself, but because of augmentation of the sound after it is radiated.

The polyfill has put a huge kabosh on the undesired box resonance on my CSi25. I am more pleased with how it sounds now, but as I mentioned, I'm sure I'll jump on a good deal for a Polk CS20!

I have the PSW-111, anyone ever added polyfill to one of these? Yesterday I took a bit of advice from Big Daddy and bought a Y-adapter for my sub & it did add a bit more sound to my system.

Add polyfill to it, but don't over stuff it too tightly. It only costs a few dollars and 15 minutes of your time. If you don't like the results, you can remove them. Make sure you buy the fire retardant type. Try Wal-Mart craft and fabric department or any craft or fabric stores where they sell material for stuffed pillows and dolls.
