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!

[@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.

[@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.

Legendary subwoofer from Logitech!!

[@DonnyTerek]

The best!

[@primecost1881]

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

[@hardystein114]

Very well thought out and built to a high standard , nice !

[@DonnyTerek]

Thank you! Much appreciated.

[@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.

[@HectorDomino.]

Man! The level of detail on your work is Insane!

[@Undar8ed03]

I agree! And that Akuma logo is the ish!!

[@DonnyTerek]

Glad you think so!

[@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. Thanks for sharing this interesting video 👍👍👍😎

This is Z2300, one of the best Logitech subwoofer's. But you transformed it

[@marcelogastonmanulak5075]

Muy lindo trabajo!!! Se nota que sabe de electrónica.

[@krisraps]

i did the same, i made an actibe sub, changed the box to my Z2300 in a huge 20hz tuned box with 500W Sub and it shakes my house appart with my other z906

[@0u1canc1v1c]

It was beautiful. Good project as a Z2300 user. Spectacular.

[@DonnyTerek]

Thank you very much!

[@khairulamilin9687]

i hv z906 for years n broken last year. recently i bought a pair of klipsch 620f n i thought the bass is already too much, until i hook my old z906 sub together.. damn it sound more awesome n ground shaking with sub

[@MrCrofty1993]

Nice work I would have done the from with the carbon fibre vinyl to

[@hilurmohammed2023]

I like that you have every tools and parts👍👍

[@yttean98]

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.

[@deadpoollocomydude7842]

Very cool and good that you reused any old sub and make it new but you should have put a bigger amp in it but that is my opinion

[@bilexperten]

I still have the original subwoofer use it every day. :)

[@DonnyTerek]

Nice!

[@KingMinhvuong]

Excellent work. Very nice subwoofer!

@@DonnyTerek your project was great 👍👌😀 I have one laying around the house but mine still works. I have a Logitech Z5500 subwooer only it works I just have that. Can you do a video on that or have you try to make the whole part you did an just sale them pre-made an just have ppl do plug an play 😁👍

[@JCMDRHProductions]

Whats the music you used at the end of the video while testing the speakers 🔊 🤔

[@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.

[@BootJamesOut]

Information very important do you know the clip that is known to go? Where to look on the plate amp?

[@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.

[@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]

Very nice!

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.

[@nothingmuch100]

Hey donny I'd like to ask what are some pro tips you could give

[@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.

[@PaulBeetge]

I have the exact Sub. Would love it if you could convert mine like you did yours.

[@DonnyTerek]

Sure, give it a try. This sub does really pack a punch.

[@trunggiangnguyenfamily8923]

Thank you so much

[@DonnyTerek]

Thank you for watching!

[@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?

[@scottwalley2090]

I too have a z2300 New from like 10 + yrs ago , good to see a referbished good old system rebuilt, i dont know what it is but these old z2300 sub amps are like bullet proof as in i blew me sats a while ago, and have used many speakers current panasonic bluray setup front l/r mains that are around 100wat, But really this sub drives the original 8 " sub driver and a 12" Boss 1000w chaos extreme cxx12 in paraelle , to some real low and powerful bass in me custom Sealed 12" 16mm g&s mdf Box, so dont underestimate the power of these bad boys , and even drived a old 15" sub!

[@miketownsend927]

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

[@bazrazin1]

i have a z5500, using its sub with PAM 8610 & my custom 2 stage LPF using lf353 from google to watch tv at low volume, made 2.1 system using this & another 8610 paired with a tube preamp for the satellites, all this powered using the set top box usb power to which a dc boost to 12v is connected, opamp PS is a 15-0-15 v dual transformer, using this for the past 3 years.Also i have that 3116 D2, 2.1 module whose sound i did not like, cause maybe the ne5532 were operated on single supply 24v.

[@DonnyTerek]

That's great! Good work.

[@ВладимирПутин-е7м]

Totally impressed. Noob question. Why did you not use the toroidal? Seems a waste of a nice toroid.

[@DonnyTerek]

Thanks! The class-D amp uses DC voltage, so I used a DC power supply instead.

[@MrCaprinut]

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.

[@DonnyTerek]

Thank you! I would go with a 2.1 amp, something like this: s.click.aliexpress.com/e/_DErjxkl . Plenty of power for most setups and easy to connect.

[@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.
