- How to convert your Logitech X530 subwoofer module into a separate active sub without needing the plug-in control speaker (the one with the volume knob and power button). You'll need, a Philips head screw driver and some modest soldering skills. Take about 30-45 minutes. Will accept phone input levels (say less than 100 mV), or small speaker levels as an input signal. I've also done a full frequency test (at 10 min 45 sec) - works down to about 15 Hz.

God, I finally found what I was looking for Thank you so, so much for making this video ! Definently gonna fire up mine. People love to sell the subbs alone, and then you have to mess with exactly what is shown here. Again, my logitech sub would be useless without this video. God bless.
Exaclty the same here.
Logitech is good. I have this same set of speakers i brought so long ago i cant remember. In 2022 these speakers still are rocking and kicking for me !
That mod was waiting to happen! took 1h and the sub is working stand alone - excellent!
Awesome work, well done!
Great video . Exactly what I was looking for a I just got this sub from an outdoor market for like 2usd and thought I can bypass it . I like how you did it but I do think if you have a spare cable from an only PC monitor you maybe able to build a little box for the power and input . I really liked this video perfectly explained
Thanks Man, You amazing work!
Nice hobby bro👍
hey mate thanks for sharing so much gold dust know how and its a great presentation. Could I ask you, what does connecting 12v to the switch do exactly (I know it puts the system in standby or idle but how does it do that and what is the easiest way to accomplish this so I can use the amp actively, and how do you add that charge? is it just a case of the switch connecting the two pins by running a wire into the circuit somewhere, or do you have to hook up a 12v psu and add a 12v charge directly to those pins? Sorry for my electrical ignorance. One advice I can offer, though, is never to drill holes in this type of cabinet, as it is finely bass-tuned at the factory and making physical alterations to the structure is known to drastically alter the sound. There must be a cross over in the circuit already so I dont think that is your sound issue, as long as a tweeter is added to the speaker connections the whole hz range should be covered, as I understand it anyway. Just thought I would offer 2 cents ; ). Thanks for any advice you rock!
cool I just hook up a 12v battery into the standby pins through the VGA for example and leave it on permanently when using the active sub?
Can i do this with the Logitech X230 sub too? Can i connect it to the PC Sound Card Sub Output? Im rocking other speakers and i have a sub left in there. It will be great to mod and use it again. Thanks bro!
awesome video!!! question - how would you connect/convert a home theatre sound system of 5.1 speakers to a laptop that has only input for 3.5mm jack. is a amplifier needed? whats the best and cheapest way to connect it without needing to buy a separate hifi amplifier
Short answer is that it's not possible. The logitech speakers can't decode, they can only amplify weak headphone level signals. Laptops only have 2 channel output from their 3.5 mm headphone socket. So that's all you will hear/be able to amplify. You need a PC (Mac??) That has separate channels outputs from the sound card. Also, the source must also be decoded as a 5.1 signal. 99% of stuff on TH-cam is 2 channel only. Only streaming services contain separate channels. Cheers
Nice . I'm having an issue getting that power chord loose even with clamping it . Youre looked fairly easy to remove. Ive tried all types of methods . Any advise?
No, it wasn't super easy. It's pretty tight (not much cord slack). I used an adjustable pipe wrench with the jaws open one notch (so teeth stay parallel), clamped it, and then wriggled it gently side-to-side to crack the binding glue on the back. Rock it back and forth - it'll come free.
👏👏👏👏👏
I acquired a Logitech Z506 Sub alone with no control speaker, similar to the X530 but not quite the same. Do you know if it's possible for me to insert a shorting wire to connect the switch pins of the DB15 and activate that way? I would like to use the RCA inputs if possible.
EDIT: Ah, it's a DB9 connector on this model. I guess I need to find a diagram.
Not sure. I'd need to sit down and think about this for a bit. If you're sure of the switch pins, then try shorting it out, otherwise, be careful if they connect into the IC. good luck!
Could you theoretically use a Y splitter to connect to the L and R aux input on the back of the sub and then run to the LFE output on a receiver and use this sub for home theatre use? Just disable the speakers by unhooking the negative wire on each internally yet still use the volume control on them. This way the LFE signal is only being output by the subwoofer. Do you suppose this would work?
Yes it might (if I understand you correctly), but you could have to ask why? This is a bit of a toy, and not suited for home theatre. I'm not happy with the LFE frequency cut of this project, but haven"t played with it enough to understand the issue fully - it just sounds a bit flat (obviously missing the higher frequency outputs which would normally go to 2 x satellites). Also, all sub outputs are mono - as you know. This project was to prove the concept (to stop me binning it). I would suggest you just buy a dedicated cheap sub on Gumtree of FB marketplace, they sell for between nothing and $50.
@@pescado99 Just connect to the mono pins going to the sub as shown in video. If you go through the satellite speaker outs you would send audio into the high Hz range in the cross over circuit, also I think there would only be a parallel connection through them and not a series one since the cross over needs to separate the two (three) signals (mono to sub, plus LR to tweeters), so as I understand it you would not reach the sub woofer this way. But you could still send a high Hz signal though the sub is not intended for that (but it will still sound). Again I'm just adding my interpretation here... cheers.
Y con esos puentes se habilitan también para los parlantes pequeños.
Si ellas son.
Amazing speakers, used mine for over 15 years. Is there a way I can use the woofer to supplement my monitors (Edifier R1280DB)? I have no idea about electronics and I'd hate to just throw out some old veteran speakers.
That's what this video is all about! The R1280DB's don't have much bottom end, so thus hack may help you, but you need some basic electronics to at least be safe around mains voltages.
@@pescado99 if I had the tools and the know-how I'd be following along with your video step by step. Almost exactly what I needed haha. Love you vids dude
@@robeywanThanks mate, always great to get some +ve comments! This whole YT thing really started out as a bit of a laugh really - and I had low expectations. So I get a real buzz when I get some good vibes back. Understand where you're coming from, like all things, this stuff is easy if you've done it before!
do you think you could make a tutorial for the logitech z506?
I don't have one lying around... Otherwise, maybe :-)
I am having an awful time finding a diagram for my goodwill Logitech z625. I can only fine the one for the z623 but it doesn’t seem to work
Keep looking. I actually use the Z623 on my PC and it really hammers. A quick Google for 'Z625 circuit diagram' shows lots of results. Perhaps refine your search? Good luck.
@@pescado99 do you recommend looking on any specific websites? To me it almost seems easier to get a new z625 set and a multi meter to figure out which pins control power
After making this changes, if we connect a small speaker into the subwoofer should it work normally?. Cause I have the same one and I don’t know how to use it
Yes, you should still be able to use satellite speakers like this.
Bro tengo un problema con un equipo de esos, cuando subo mucho volumen en una cancion que tenga mucho bajo se dispara me podrías ayudar?
Sounds like it could be a capacitor in the power supply. Have a look and check for bulged capacitors or burnt components. Bueno suerte!
Hy, nice vid. Do you know, where to find an circuit plan for this?
Hi, mine has long since gone. I searched on line and found it pretty quickly using the model number. Good luck
@@pescado99 tryed this already. nothing to find. :(
Hello friend, I have a Logitech z313 I bought it second hand but it does not bring the mouse where it turns on and the volume is raised, what can I do, help
Hi, have you tried to Google the issue? Do you mean your Z313 does not have the remote? I'm not sure if my fix applies to the Z313. All I can suggest is to open it up and check to see if he pin connections look the same as the X530 in the video and try a similar fix. Good luck and remember to do this safely, with power turned off.
So I don't need to open it at all actually? Just solder a power switch and input to the specified DB-9 pins?
Yes, you could do that.
Tengo una que le farta el cable VGA el
Modelo z623 trae el de vulumen del bajo y el de speek
Bueno, no hay problema con esta.
@@pescado99 cuáles son la línea del power
Can l make same on soundbar wireless subwoofer?
No idea.
Tengo una encontró 506
can i connect the periferals speakers with this mod? or do i need the control speaker.
You need the control speaker with this mod for satellite speakers to work. The whole idea is to be able to use it (in some form) without the control speakers. Good news is, I've tested it and it sill works fine with control speaker attached.
@@pescado99 ok i see thanks, can you show how to create a control module for replacing the control speaker, i need to find out a way to make the 15pin a volume, on off, and aux cable for my setup.
I just purchased the Yamaha HS8, but I still want to use my Logitech Z623 subwoofer.......could anyone help me out?
Assume you mean the HS8 active satellites? You could use this mod from your Z623 sub, but haven't checked the circuit board for this mod. Do you now have the Z623 satellites? If not, I'd bypass the active connection in the yamahas and connect them to the Z623 via RCA plugs. Good luck - should sound nice.
My Logitech z623 vga male 15 pin connector is broken bro can you help me please 🙏 15pin new connector change connection please 🙏
What do you mean broken? If you've broken a physical pin from the connector plug, there's not a lot you can do because the plugs are potted (sealed). You need to give more information.
😃😃😃😃😃🥇🥇🥇🥇🥇
What would an active cross do, and why is it desirable?
It allows selective frequencies for amplification, as well as matching the amplifier and signal source to the frequency response of the speaker.
@@pescado99 oh, I thought the internal electronics would do this already.
Somebody tryed chaged power supply to 12v dc and connect this subwoofer to car radio using mono Jack > 2 RCA cable??
Yes, there is a comment further down on how this might be done (using secondary windings from transformer).
The input of this board is AC, I want to run it with DC, how can I do it?
Yes it would be possible, the supply is 240 VAC. The transformer on the main board has a secondary winding that steps the voltage down (not sure, but typically 6v to 9v), it is then rectified with a diode bridge rectifier, and filtered with capacitors. So technically, you could pick up the secondary winding from the transformer where it connects to the diode rectifiers - you could measure it and replicate it. Make sure you get polarity right. Would suggest at least 2 Amps on DC supply.
@@pescado99 thanks
@@pescado99 Is it okay if I give 12v to the capacitor in the input section?
Input volumes too low that why the sound is low.😂
that is really dumb, why would you not cut off the power to mains to make a hard power switch and leave the internal always on, so it would not be in standby
Yeah, you could do that, but isolation of the power supply wasn't the point of this video. As always, all comments welcome :-)
чел болтает абы.. 99%
Falso no se olle
Por que? No se falso. Esta cierto.
En algo la habras cagado estimado Mr. Mora o ya estaba así antes de llegar a ti... Ya que acabo de realizar el procedimiento que nos comparte este man, con lujo de detalles, en un equipo del mismo modelo y ahorita ya lo tengo funcionando. Thanks Mr. Pescado99!
