PSW10 Modification

skrolskrol Posts: 2,596
I just picked up a mix and match sub (PSW10) and surrounds (4x RM7s and RM7 center) at CC that I though would be fun to start an entry level HT system with. I figured I couldn't go wrong at $97 for the package. I have read good things about the PSW10 with the only real complaint being some port noise at high volume.

I was wondering if anyone has tweaked theirs up any? The PSW10 looks to have good potential but I have noticed some possible areas for improvement.

First is the lack of flaring on the inside end of the tuned port. I'll likely add a flare.

Also, inside the box there is a board (support) between the driver chamber and the amplifier that has sharp corner edges. I plan to round over the corners to reduce turbulence.

There is also little cabinet damping material. What is there is glued down but not placed directly behind the driver. I plan to line the walls with material and specifically behind the driver.

Lastly, I may replace the feet with spikes to improve stability.

Any other suggestions?

All these mods should be fairly inexpensive and will hopefully result in a killer little sub.

FYI. The driver is a RD1018 and appears to be very similar to the Polk car sub DB1040.

    Youre luckly!.. I bought the same sub in CC for $109 alone on the clearance sale for my bedroom. I have AccoustiMass Bose System at room, but that Sub Bose its not enough, so I add this little baby. Sounds pretty good, and helps the bass sounds on movies and music for my bedroom.

    But I think its not set as I like. The manual says to connect to the Left or Right RCA, or use a "Y Adapter", and move something counterclock full, Its that moving the crossover to 250?, or to 80? to get the LFE Effect as manual said? Please help. Also if you found anything to improve the sub, let me know. Thanks

    I would strongly recommend the y-adapter idea mentioned by the previous poster- worked wonders for me

    Sorry to resurect an old thread, but I have been experiencing quite a bit of port noise on my new PSW10, and I wanted to see if there was a result from skrol's modifications.

    I have added some polyfill, and without testing too much it seems to have made a slight difference (but I'm nopt sure how much to use on this sub, there seems to be conflicting advice on Polyfill in a ported enclosure) but I wanted to know if there is more I can be doing to reduce this port noise.

    Thanks very much!

    I really have not gotten around to playing with the PSW10 yet. I agree that there is port noise at higher volumes.

    Put a sock in it. No I'm not kidding...though it will reduce the lowest bass you can get from this sub...just block its port with something and see if that gives you a bit more control over the sound it puts out! Not recommended if you have a big room?

    Thanks for the suggestion. I am going to keep playing with the polyfill, including in the port (can't hurt to try) and then try plugging the port to see what it will do.

    I noticed while testing the sub that my seating position makes the bass produced from the sub sound/feel very weak. Walking around the room gave me a stronger sense of the bass, so I think that if I can get a more optimal position of the sub, I can turn it down a little, and the port noise will reduce as well. We'll see!

    Thanks!

    Somebody knows the TS parameters of the RD1012 driver?

    Gents, everything has a purpose. The psw 10 sub was meant for small speakers, in a small room. Trying to get the volume out of it that you may want is beyond it's capabilities. While there are tricks and tips for better performance, the sub is limited at what it can do.

    Try putting the working sub in your primary listening position. Then walk around the room until you find where it sounds the best. Switch places with your sub and you should be getting the best the sub can deliver in that room.

    As per another forum thread, I would like to direct PSW10 owners to the following video, which shows how to remove the internal "rat guard" from obstructing the port opening, thus almost completely eliminating the famous "chuff" which has ruined the reputation of this subwoofer - with this simple 10 minute mod, the personality of the PSW10 changes dramatically, for the better:
    HT1: Polk CS175i+ L/Rs with Vifa 1" dome tweeter
    Polk R10+ surrounds with Vifa 1" dome tweeter
    CSW Center Channel Plus with Vifa 1" dome tweeter, dual 1 inch bass ports in back

  • Will this mod damage the sub at all? Just wondering.

    Maybe just a smidgen where they screwed and glued the rat guard. Some report that the glued pulled a little MDF off but other than that no damage .....well that unless you have a rat problem

    As a followup to this. I purchased a PSW10 to go with my Vanatoo T0's per their recommendation. Initially I was pretty unsure about the sound. After about 15 hours of break in and removing the rat guard I am quite pleased at the value. Note the rat guard is no longer glued. And there appears to be more fill and and wrapping of the cables internally then some of the earlier images I have seen. Great deal.

    +1 on that xophere. Welcome to the forum :smile: . I saw the video as well and removed the "rat guard" from my 108...great results :smile:

  • I recently decided to build a Surround Sound set up and focused on POLK speakers since I came across some great deals on Polk equipment, including two PSW10 subs. I am quite happy with them so far since I get plenty of bass out of them with the little I have been able to figure out so far and I don't have any port noise from them. The only negative I have with the PSW10 is that they aren't matching with one being black and the other being cherry finish but that is no big deal. I have purchased a used PSW505, which I am yet to physically get, thinking I would need it due to reading so much negative feedback in the internet with many stating that one 12" sub is better than two 10" subs. I obviously have to keep an open mind and wait until I install the PSW505, but so far I'm thinking I might have jumped the gun and was premature in buying the PSW505. I might still use some combination of the three with this set up plus I am still looking to put a Surround Sound set up in my bedroom so I am sure I will want to use a PSW10 there. Any input on one 12" vs. two 10" vs a combination of three.

    Hello ultrasound first and foremost welcome to the forum :smile: . When it comes to your sub setup it depends on what you're looking for. the one 12" will dig deeper in the bass than the 10", but if you want a more even response in your room the use of two or more subs is best.
