DIY 200W Active Subwoofer from Old Logitech Subwoofer

[@fondu-design]

I picked up the EXACT same sub woofer from hard rubbish and, after I figured out it was originally part of a Logitec-only set, realised a separate plate amplifier might save it: I'll be following your steps to the letter (although I might respray the cabinet along the way). Thanks for this!

[@DonnyTerek]

That's a great find! These subwoofers are amazing to this day, hope yours turns out great.

[@tomatoplot]

Cool project! I recently got this same subwoofer for cheap at a thrift shop. While it works fine, I decided to turn it into a sealed subwoofer, to get more even frequency response, and a tighter sound. Tore out the port, added some foam padding to the interior walls, and covered the port hole with a piece of plywood. Sound much better than before!

[@DonnyTerek]

Thanks! Would love to hear the difference to the ported enclosure!

[@tomatoplot]

@@DonnyTerek Would be hard to record it directly with my equipment, but as you'd expect, it's a flatter and punchier response. Loving it!

[@zedingk9764]

Looks great! a lot better than before, especially that carbon touch, was really worried about the volume knobs hitting the wood but turned out the be great.

[@DonnyTerek]

Thank you a lot! Yeah I was afraid myself that the knobs would hit the panel but it turned out great.

[@ВладимирПутин-е7м]

Carbon Vinyl Wrap looks excellent. Should have done the whole thing in the wrap. I'm going to fix up my speakers with that wrap now.

[@matthewj.hullbasbmf5001]

Outstanding repurposed subwoofer. I’ve done similar with an old Bose Acoustimass and a Polk subwoofer. These new inexpensive Chinese plate amps are great for projects such as this one.

[@DonnyTerek]

Thank you! Exactly!

[@slimjim1104]

Only downside is they dont have the dsp tuning made for the driver but still a great way to bring a good little sub back to life.

[@primecost1881]

These oldes Logitech z2300, z2200, z680, z5500 was using very good and really powerfull amps.

[@paulogilvie7072]

Thank you, Interesting build. I have one of these also but the sub channel stopped working (was down to a whisper. Tried to figure out what was wrong but have no idea so replacing the amp seems like a great idea, make it blue tooth also. Any reason not to rebuild a bigger speaker box and put everything into one rather than using the original sub box? Interesting to see the comments about the original satellite speakers not being up to par.

[@DonnyTerek]

Thank you for watching! Glad you liked the video. I guess you might have a dead chip on the amp just like I did. That's why I got this sub for real cheap. Though I decided to go with a 2.1 Bluetooth amp to be able to connect a pair of speakers as well. Personally I don't see a point of rebuilding the sub enclosure since it has a great and compact design. It could use new paint or veneer on the outside though.

[@vdochev]

Good job. I'd suggest you try adding some damping material inside that sub, it'll make it denser and will have the effect of having a larger cabinet.

[@waltergeldof4923]

What a great job that you and your colleague are doing together to restore all that old active sound box with amplifier. When I see how you work, it gives me the feeling,,,, This is also something for me to restore all those antique sound boxes in no time to almost as new. Good job my friend.

Great conversion! I have a Phillips SPA5300/10 pc speaker system with 10" subwoofer that I use to connect to my phone while working in my little mancave. Sometimes it muffles down after some playtime (hours) and after a while it goes up to normal again. Any recomention to new ampboard to replace the current one? The system is rated at 100w by Phillips. Love the sound btw. Due hearing loss and hearing aid useage I do not like sharp discant sounds.

Recycling, that is the way to go. The Logitech Z2300 subwoofer still has a lot of life to it. I was thinking of using mine, alas I gave it away. Lots of second-hand units around, cheap, buy 4 units make them 2 woofers in push pull, and 2 separate subwoofers in stereo mode I believe the sound will be awesome.

[@DonnyTerek]

This is definitely still a powerful sub and can pack a serious punch.

[@UmbreWolf]

I still haver mine but i'm still trying to find the orginal remote for it, hard to come by and pricey for a working one, ive considrred converting mine for just that reason.

[@miketownsend927]

How did you hook this up to your stereo L & R speakers?

[@Divyesh_Sinha]

Bro That sub is just running at 75w cause the tpa 3116d2 only gives 75w for 4ohm sub Use a different amp like the 1943 5200 type

[@Durkhead]

I thought it was dependent on the power supply he said he was using 8a most of those only come with 4a maybe it's a different version it had a pretty big heatsink

[@momfiethehunter504]

@@Durkhead he used a 4amp powersupply but the text on screen said 8amp. He could have used a 8amp psu later on in the video but we dont know that

[@DonnyTerek]

That's a great point. To me 75w is plenty for this sub. I was aiming for a wireless amp like this one, but I could definitely get more power using the 1943 5200 type.

[@DonnyTerek]

Yeah I did not have an 8 amp supply on hand, still waiting for it to arrive.

[@momfiethehunter504]

@@DonnyTerek are you gonna link that other one if you find one that is similar to the one you used now

[@Domaudeo]

Great job! I love the "carbon fiber" finish! Could you keep the original internal toroidal transformer with bridge rectifier to avoid using those noisy switching power supply brick?

[@DonnyTerek]

Thanks! I guess it is possible to leave the internal transformer, just not sure how it could be converted to DC.

[@Domaudeo]

@@DonnyTerek you can do a very simple bridge rectifier with only two cheap electronic parts: a diode bridge and a capacitor. Also some amp board sometime can take ac voltage directly as they have the bridge rectifier onboard.

[@DonnyTerek]

Hey that's a great idea. I might use the old amp for a different sub or vice versa.

It's a Logitech Z2300 subwoofer. 8 inch, 8 ohm driver, 120 watt RMS. Nice Class AB amplifier in that thing. Shame he didn't reuse it.

[@DonnyTerek]

Thanks for making that clear. I would have a hard time rebuilding a blown amp and making it to a 2.1 system without the wired remote control.

[@dbyoltech9225]

Great work super. I'm also tried it double subwoofer 👍

[@DonnyTerek]

Great 👍

[@micling2199]

my Z636 Logitech sub has a RCA L/R aux input on the back. Could I 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?

[@GiulioZelante]

is there a way to do that with the logitech z5500 and a 5.1 stream?

[@slimjim1104]

Def done similar to old subs myself. With cheaper subs the amp is always the weak spot. Although it looks like it used a solid torrid ab design in the og setup.

[@WarmSpringsWarriors]

I have a old THX logitech 5.1 and its still working. I tried upgrading to the newer version of sub with controller but they removed the extra line in, so I went back to the old system. Mostly because they downgraded the subwoofer design. Paying more for less sound quality was the products Logitech was making before they left Fremont to Newark.

[@ToniLixSim]

i have 6 of them logitech :) they are super,, but again i open and make it with new cable to connect other bigger subwoofers with their amp. and stereos edited, they are just nice and strong amp on it

[@DonnyTerek]

[@vantum8471]

I have a set of Z2300's, and I'd like to say that this is a cool mod. However, a few things I wanted to say: 1: You're replacing a Class AB amplifier with a Class D amplifier. The sound is going to have MUCH different characteristics. I get that it is cheaper to get a Class D amp to mod it, but I would have personally found it cheaper, easier, and better to replace the parts that broke on the old amplifier. 2: MDF is a great and cheap material, but if you ever planned on using it for a while (Which I assume you aren't), I would have used a harder and real wood. Other than that, awesome build! Creative repurposing of an old sub that still kicks like no tomorrow.

[@DonnyTerek]

Thank you! Really appreciate your input on this build. 1. Since the amp was burnt and it didn't come with the wired remote control, it was a lot easier to just replace the amp with something different that would also allow me to make it into a 2.1 system. 2. Actually a lot of speakers are built out of MDF, even the Logitech sub boxes themselves.

[@endall39]

@@DonnyTerek 1. I’m very familiar with this sub and amp, and I would bet that class D is putting out more than twice the clean power of that cheap A/B, especially with a 24v 8 amp power supply. 2. I agree with the use of MDF, but I though it should be thicker for such a large panel. I’m thinking it will flex a bit.

The amp spec shows it runs 100w at 2ohm on the sub. How much difference is there compared to the stock power output of the sub on the stock amp? And would 25w 6ohm speakers work well? Thanks

[@DonnyTerek]

Hi! The sub of the Z-2300 is 8 Ohm as I remember. I wasn't actually able to test the difference since my stock amplifier was blown, haha.
