How to disassemble Logitech Z-340 sub-woofer

Anyone know how to disassemble the Logitech Z-340 sub-woofer. Apparently the speaker bezel, and then the speaker needs to be removed to get at the power transformer. What's the secret to removing the speaker bezel?

The speaker bezel can be removed in only two ways:

1) Somehow remove the grille in order to get a the screws which hold the bezel onto the cabinet. I tried to do this and couldn't get it to budge. Once I got the thing open I observed that Logitech used a LOT of glue to hold this thing together.

2) Drill holes THROUGH the grill above each of the 8 screws large enough so you can loosen the screws.

Once you get it open, you'll be shocked to discover what you thought was the subwoofer cone is actually A ROUND PIECE OF CARDBOARD fastened to the foam. The 4" driver is behind this fastened to a board halfway back pointing into the chamber containing the electronics.

You can get to the power transformer, but good luck removing it. The screws are nearly impossible to unfasten; more glue but more importantly incredibly awful access to the nut and screw (yes, a screw, not a bolt).

I wouldn't pay 5 bucks for this system. Luckily, I didn't.

You just remove the grille by prying it out with a flat head screwdriver. In mine sub it wasn't glued. Then you unscrev those black screws visible through the grille.

Where can i purchase the audio cables that connect the Logitech X 230 sub woofer to my laptop and mp3 player


Usually you can purchase audio cables for speakers and sub-woofers from any or authorized PC outlets.
Just explain to the dealership what you want to connect it to and they will shoe you the right "jack" to buy.

Only have the sub itself, Can I still use it and if so how?


Unfortunately you will not be able to use the sub-woofer by itself because the input for the Logitech X-530 has a special cable to connect to the sub-woofer. You could always try looking on eBay or Craigslist for replacement parts.

I recently purchased a new Denon AVR-391 receiver and am having a problem hooking up my subwoofer. It seems that the Denon has a pre-out RCA looking output and my subwoofer uses conventional speaker wire. ...


Hi,
Your sub-woofer apparently does not have an amplifier built into it. This type requires you to use your front left and front right speaker output to got through it to your regular speakers. It is called a passive sub-woofer for that reason.
To set it up, Connect your front speakers to the "output" of the sub. It should say "to speakers" on it.
Then connect the Speaker Outputs for the left front and right front on your Denon AVR-391 directly to the Sub. It should say on the back of the Sub "to amplifier".
Here is some theory you should know, if you don't already know it, that will help you get a satisfactory result in setting up this system.
There is a condition on setting up all speakers and subs that not everyone know. It's call "phase alignment". Phase alignment (A Good Thing) refers to all of the speakers in a system moving in the same direction (in and out) at the same instant in time. This gives you much clearer sound and better response from your sub-woofer.
Phase Cancellation (a bad thing) is when some of the speakers are moving out and other moving in during the very same instant in time. It causes problems in sound.
IN A SUB-WOOFER, IT CAN CANCEL OUT THE LOW NOTES.
Here is how to handle it:
On the back of the receiver the speaker terminal outputs are colored Red and Black. Black is considered negative and Red is considered positive. On the back of the Sub woofer and on the speakers the same colors apply. MAKE SURE THAT ALL OF THE CONNECTIONS GO BLACK TO BLACK AND RED TO RED WHEN CONNECTING UP THE SPEAKER WIRES.
The system will work either way. But you will have severe bass loss if the woofer wiring is out of phase because of phase cancellation.
Hope this helps,
Best Regards,
Mark
