Thanks, Glitch!

I would like something a bit more substantial eventually, maybe I’ll find a piece of granite that goes with the look. A darker plinth would be nice that way I can do some different, richer colors for the printed pieces. Only thing is I need a few of them.

Ultimately I will have several of these on top of a shelf in approximately this arrangement:

The plywood was for sure not the original direction but it makes for a nice, warm and light-hearted version of the design.

If anyone would like to make their own, feel free to download here: evanbunner.com/downloads or reach out to me if you are interested in getting them printed.

I received some quotes for glass shelving and boy was it pricey. Seems like B&O negotiated a good price with its suppliers back in the day… the tinting and beveled corners seemed to drive up the cost a lot. Largely though there was a ton of polishing involved to get the edges smooth.

At any rate, I decided to just move on with some scrap ply from the woodshop. this is ~12.5mm ply with some white PLA printed ends. I made 4 shelf plinths last night, two in each length. Going to make a few different colors to see what works best with the birch ply visually.

As always, I am starting random DIY projects and this one *should* actually make it to the finish line in a few weeks. I have modeled up a clone of the A5/A6 CD rack! I am currently getting quotes made for the glass in both sizes like the originals. The end pieces will be 3D printed.

I am a huge CD listener and have a few hundred CDs that will be put on display in my new music room here at home. I plan on building at least four or five of these eventually. I like the idea of having a few groups of CDs to organize by genre instead of organizing alphabetically like I usually do.

Old thread but thought I would just share my most recent order of 3D printed stands for the BeoLab 4000. I continue to 3D print these for a small fee and am happy to try and build them in various colors to match the different colored BeoLab 4000s.

A bit of a “later gram” as I shot this about a week or so ago and the forum was “404 not found” so I couldn’t post it! Better late than never.

Here are my BV M100s in a new listening room / home office combo in the making. A bit of more mashup hifi with some fun bits thrown in. The Moment is to-be-integrated still and I’m hunting for an interesting CD player to add to this system. Might also swap in a different preamp as the Lexicon is total overkill for a stereo setup.

I think that the Beolab 50 is one of the best styled speakers that B&O has ever made. However, B&O may have done “too good” of a job making them look “not like a speaker”.

This is an interesting take. It is indeed elegantly styled however I think we are starting to split hairs (we is everyone in this thread). What I think is the distinction between all of these speakers and our comments above is the geometry.

50 is truly a unique animal in terms of B&O speaker design. There is not a single, slender, delicate, maybe even striking feature about them. It is a heavy looking speaker. The 5s have aluminum discs from outer space and a strange, slender neck with a step change from its conical base. 18s and 28s are packed with unique details like the acoustic lens, or moving frets and the floating column/sub combo on 28.

I can see how 50 would generate little conversation. I think generally speaking, most average folks expect speakers to be big and heavy. The 50 is big and heavy. It is a speaker.

I have almost no experience listening to BL2500s. If the bookshelf category is a constraint for this project, you could consider BeoLab 4000s, those are indeed very affordable these days. However, not sure how “close” these two speakers are in power and spectral capability.

If the speakers aren’t confined to a bookshelf then I would recommend a floor stander. 8000s are also great value these days.

I am trying hard to think of any working B&O items in my garage haha! Certainly nothing that is in use.

BS2300
Penta amp x2
BG1202
BG4002
BL Penta x2
BV Penta x1

…all busted or in some state of waiting on repairs.

I think the only working units are extra Beo4s! 😀

Hi Bogener,

Indeed, there will be a separate volume for the midrange speakers, just like the original Penta design. Overall, the plan is to utilize the extra volume (there is a lot in the current design) I have to try and do away with the port. I prefer sealed speaker designs personally so that will be the initial direction of the acoustic concept. However, all of this still needs to be verified with some measurements. Basic system resonance and overall response still need to be measured before I can make any concrete decisions. If I end up going back to a ported design, I will definitely lean on my 3D printer for it. Time will tell!

Currently the rest of the cabinet box design is… well…. very box like 😀 The box is intended to made from wood as it is currently modeled below.

Here is the current (but very basic) interior layout of the cabinet. You can see there are a few small vertical pieces that make up the midrange cabinet volume. The horizontal piece is simply there for bracing and stiffness.

 

I really need to get back into this project! Life has been in my way lately, stealing away spare time. Also the furniture rearrangement in the house has disrupted the need for this speaker altogether so there is currently not a strong household demand for this beast.

Working on a 1994 Trek road bike restomod project – but not without some music playing on the BeoLabs! I had two of these for less than 100 euro’s, stripped them and had the cabinets powdercoated. As they are centerchannel speakers I feed them 2xL and 2xR (tweak in the RJ45 wall outlet). They are connected to a BLC that gets the NL from an Airport Express. Happy with my (once) 6000 euro garage soundsystem 🙂

This is awesome! We clearly need to start a garage/mancave/workbench photo thread!

Hi Evan, I agree with Johan, that looks very good, as the „stripes“ (do you say something like that in English?) of the BV7‘s back are taken over into your design, really very nice. Is the apple tv getting on in that mount? Hopefully not very much. Edit: btw, congrats also to the BL4000 stands! 🙂

Appreciate the comments, thank you! Mission accomplished – I did want the mount to look like it belonged. Apple TV seems to be just fine in there, the ventilation seems to be working alright. Glad you like the BL4K stands as well 😀

Hi Evan, that looks very natural! There is this thread where a range of ATVs was listed for dimensions and IR sensor location: https://forum.beoworld.org/forums/topic/fitting-a-new-apple-tv-into-a-beoplay-v1/. Maybe useful. Regards, Johan

Hi Johan – thank you! I may release some other designs depending on demand, appreciate the link!

Here it is all done, a nice little weekend project! I plan on offering this for sale, if anyone would like one, please feel free to PM me. Not sure what other Apple TV versions might fit but this is currently designed for ATV 4K Gen 2. Also, if there are other 3D printable / CAD related challenges anyone has been thinking about, would love to hear them.

I bought my MK1 BY7-55 in 2022 for 1250GBP, with high motorized floor stand and a BeoLab 10 and a Beo4 included. The dealer even included a 1 year guarantee. I’m pretty sure, at the time, it was one of the cheapest in the UK. Unbelievable value honestly. The depreciation is staggering!

In US money this is apparently $22,140…?

Lately I’ve been trying to clean up my main AV setup – the BV7 and BL5 system in my living room. First task is to make a home for the ATV so I decided to design [and then print] a mount for it on the uprights of the floor stand.

Here is the design so far. Might change the appearance a bit but currently working on tuning the geometry to fit.

I’ve been inside my Beovox MS150.2s in the last day or two. A few years back, one of the midrange domes started distorting and, on taking it apart, it turned out that the voice coil had become partially detached from the former and was rattling around in the gap. Odd, but a replacement driver from Beoparts (now: Danish Sound Parts) fixed it. Then, about six months ago, I realised the other speaker was making similar noises. I took it apart on Monday and, yes, you’ve guessed it:  Well, another replacement unit is on its way to me, but I was initially taking this personally and wondering what the universe has against my MS150.2s in particular! However, lying in bed last night I had a sudden realisation. When I took the speakers apart to replace the first failed midrange, I noticed that in the past, someone had obviously re-capped the speakers and done a pretty shoddy job of it. Consequently, when I was ordering a Danish Sound Parts capacitor kit for some other B&O speakers, I ordered a kit for these and fitted it last year. During this process, I found that whoever had done the crap job had fitted a 33uF capacitor where there should have been a 3.3uF in the same place in both crossovers. Checking the circuit today, it turns out that this capacitor is in the high pass section of that very unit, so it would have dropped the crossover frequency drastically, and sent bass frequencies to the dome. No wonder the flippin’ coils keep cooking themselves and falling off! Hopefully, it’s not a fix I’ll have to repeat again. Meanwhile the next loudspeaker job awaits, but this isn’t a B&O one – sorry!

Interesting story, Adam. Cool that you were able to find the root cause! Who knew the capacitor values were so important! ;D

Hey BeoWorlders,

The final 3D model of the upright table stand for the BeoLab 4000 is now available for you to 3D print. I’ve tuned and tweaked my CAD model to create as accurate a copy as possible but with some notable changes to enable 3D printing.

Special thanks to Dick Andersson “Beomaster” for truly enabling this project by supplying me with an original stand to put my calipers and radius gauges on to make sure the model is as accurate as possible. Thank you!

You can now download the STL file from my website here:
https://www.evanbunner.com/downloads

I’m now printing units for those who have already reached out to me about getting some of these made. They will soon be in your hands! If you would like me to print them for you I would be happy to do so – please just reach out and let me know what you are looking for. I’m US based but can help ship them internationally too.

Enjoy!
Evan

Forgot to share the results! Pretty good for estimating from photographs. Soon I’ll have a real stand to put the calipers on and make a more precise clone.
