This is my favourite (up until 2023 of course) 2-Way stand mount speaker design yet. It features a tweeter in a waveguide for wide dispersion and a racetrack shaped passive radiator for deep bass. It's a great value for money build, and it sounds fantastic! Build plans for these are available on my website at the link below:

A 2nd order network on the tweeter at 1.5khz with a 3/4 in dome?! Excellent design work. The waveguide with a wide surround tweeter make that possible. Great driver selection. I'm happy to see some use of SB Acoustics and Seas in this project. Thank you sir!

Great to see you in action. In other vids I saw only your hands, but this one has the human factor well recorded. Surprising bass sound. I've always liked the way KEF use their ABR designs. They open out the sound without the over-excursions that some vented cabinets suffer from. I did wonder if some of the tweeter/waveguide section could have been speeded up to hold viewer interest and attention. Other than that I really enjoyed the vid.

Your most beautiful pair since the Dynamites! As you quite often use 3D printed parts to make your life easier, let me suggest doing this for the waveguide and tweeter as well - just a round piece with a "step", the smaller diameter being the one of the tweeter and the other being the one of the waveguide, then you could just place them perfectly very fast; drilling the holes, securing them, done :) if I ever build a 2nd pair of yours, it would be this for sure!

@@Dev_Everything I think you misunderstood what I was trying to say, so let me elaborate (which is hard without images, haha). Imagine that if you cut it open, it looks like an L The part would only be used to align the pieces, nothing else. Basically it's a ring that "clips" to the waveguide from behind, not sure how you call the area, the part that gets drilled later. And that printed part should have a 2nd "step", which has the outer diameter of the tweeter, so you place that one inside and and have a virtually ideal alignment as all parts should already be centered. I'm sure it's not perfect, but I'd bet it's at least as precise as doing it by hand - just way more convenient :)

I think you could use the 3D printer to create templates for cutting the oval shape openings and flange pockets. Also by measuring the tweeter hole pattern and the diameter of the waveguide center hole you can create a perfect fit drill guide (basically a circular sheet with the same hole pattern and a shallow cylinder in the center to align it with the waveguide). Maybe not worth it for a one off (or 2 in this case) but my OCD would not let me eyeball it :)

SEAS speakers always punch well above their "weight" class. I enjoy your content but in this episode I saw and heard a few things that I may, humbly, like to send notes from my life of home/car audio sales/instalation/fabrication and years of construction ending in a full blown contractor before becoming disabled. (I did not want you to think I'm just yappin from the cheap seats) .. now .. a little spray adhesive on the sides of the little fluff you put over the crossover will stop it from dancing with the bass up the wall.. big fan of super 77 for most any application of spray.. more .. a mix of water and just elmers glue 50/50 makes an excellent sanding sealer and helps big time with the "end" grain of the mdf sides. Just some thin coats and it sands great when dry .. more .. the binding post. I shed a little tear when you put steel binding post in that fantastic built and designed speaker. Ferious anything affects and effects the signal and ultimately the sound. I did not believe it untill a friend of mine quite a few years back replaced his home speaker binding post with copper "tube connectors".. back then very esoteric but today readily available. Those that know the difference between listening and hearing music can hear it with little effort and lastly a note from my construction side.. your air powered brad nailer. That looks like a Bostich 18 ga toi me. Should be easily rebuildable or taken to a service center. Nine times out of ten its a simple oring. And penumatic tools beat battery tools every day of the week. I have DeWalt 16/18 ga brad battery nailers, Passload/Hitachi battery spark butaine power framing and brad nailers and a large mix of the air types. In the cold and heat the battery ones suffer. They have a limit as to the depth of drive especially half power and down. Stick with the air. You will appreciate it. Subscriber for a long time and usually keep my "internet" oppinion to myself but today was in share mode. I hope I did not overstep and know I am not being a Karen of any kind. I say all this with humility. Your the one doing the work I'm just watching. God Bless and keep up the content.

@SoundBlab 11 ай бұрын

Thanks man, appreciate the comments. The binding posts are brass with a nickel plating, no steel. My brad nailer is new, so not sure it already needs a rebuild, but even one I had before was not great either, thats why I got a new one. But in the meantime I got a battery brad nailer, and I am much happier so far.

@Obsfucation 11 ай бұрын

JamesHobbs1460: What concept in physics would you accrue to this supposed difference in “sound quality” WRT the materials for your connectors? Also, could you fill me in to how you performed your ABX or, at least, double blind test that led you to believe that the sound was different? Finally, how was it different? FR, distortion?

@SoundBlab 11 ай бұрын

I have not performed any AB testing on connectors. I have never really been able to hear a difference to be honest. I think that these small differences are generally only audible in very very high end resolving systems in properly treated listening rooms. However, when it comes to steel connectors it is fact that copper and brass for example does have better conductivity rating than steel, so from that perspective alone it makes sense to use whatever has the better performance. That's really all I'm going by, but it's not a big deal to me. As long as I enjoy the music, I am happy.

Hello. I'm looking at doing a similar thing with the SB Acoustic 5" coax. It's for my camper where space is tight in the back area. I'll have a sub in there but i still need kick bass from the 5" and thought about using passive radiators to allow for a smaller enclosure. SB Acoustic do a radiator to use with the coax, it's the same size. I don't know whether to use this or the race track. I read that the radiator should have larger area than the driver. I could use two 5" radiators i suppose, even two racetracks on the sides but it's all guess work at this point. How do you select parts or calculate enclosure size or port size?

Hey SoundBlab, I love your builds, but i've always wondered, after extensive research i have yet to find an answer to my question about passive radiators, in this case i got 1 active and 2 passive radiators, is there an acoustical advantage to putting the PR's in the rear or is it better to have one on each side of the enclosure. i still have not found one who could give me an answer to it. i would understand with the single PR that it is better in the rear cause of vibrations.

@SoundBlab 8 ай бұрын

With 2 PRs it is probably best to go one each side to achieve force cancellation and thus damping enclosure resonances. PRs on the rear can make speaker placement more difficult in a room, since you probably don't want them too close to a wall. The placement otherwise has no effect on the frequency response other than what room placement and the room itself will introduce. It is similar to a port, front or back makes no difference, but the same advantages and drawbacks counts as does for PRs. PRs also work well when you have both on the same side of the enclosure. This way you have more freedom to swop speakers around to have the PRs facing either inside or outside depending on what works best in your room. It's probably more flexible than rear mounted. I am currently working on a 3-way floor stander with 2 PRs on the back, but as said before, it is similar to a port on the back.

Where did u buy the bass driver, tweeter and waveguide?

@jondonnelly4831 6 ай бұрын

Hi, i have a set of creative labs T100 speakers and to my ears they sound really nice, fast puncy and surprising amount of bass that hits harder than speakers 6 times the size. Only thing it lacks is clarity. Could they be reproduced in HiFi? Really impossible wtf physics breaking lows, im guess they are T line but seem way too small and light for that.

@SoundBlab 6 ай бұрын

I doubt if they are t-lines, most like ly they are ported enclosures with a single full range driver, which perhaps explains the overall lack of 'clarity'.

Good job. Why not Monacor WG-300 ? I think so that better and more universal when you choose tvi.

Hey all, I do have a question regarding the passive radiator. Can it handle two of the sb chassis or will it cause too much excursion?

@SoundBlab 18 күн бұрын

Off the cuff, I would say no. But I have not modelled it to confirm. However form this model I would suggest it is not possible without compromise.

What diameter did you cut the inside circles for the PR? I've bought some of these and I'm thrown by the supplied gasket foam on sonething that seems proud of the flange itself. I wasn't going to flush mount the outer flange but its not clear from the data sheet what the geometry is behind the foam on the back. Also to anyone reading: don't but the SB supplied 50g weights for use with these - they don't fit. Unless tou put them at the end of a very long bolt, and have lots of turning moment acting on the spider and surround. Better to just get short bolts and some washers, I got mine in a DIY store - cheaper too..

Looking good! One question, not to bash just for my information. Did you adjust something on the pr, to change the tuning? I have a floorstander in the works for a friend of mine with this waveguide combined with the vifa xt25tg-30 and dual 16pfcr. Tweeter combi borrowed from Heissmann acoustics, maybe you're familiar with his work. Keep up the good work :)

@SoundBlab 11 ай бұрын

Thanks. There was no need to add weight to the PR, it performs optimally as is. It can be extended slightly with about 10 to 20grams, but opted to keep it simple.

Serious question. I'm just getting into the hobby and I want to build many speakers... but what if people don't want to buy them... what do you do ?

@SoundBlab 8 ай бұрын

I can't really answer that, because I have no experience selling speakers, but I do know that it took me many many years to learn how to properly design and build speakers, and I am still learning. If you are only getting into the hobby, I would consider that you spend some time to learn all you can before committing to such a venture.

@hermangaviria690 8 ай бұрын

@SoundBlab I guess that my question also lies in, what do you do once you have too many speakers ?

@SoundBlab 7 ай бұрын

This is a problem... I try to be efficient in using various combinations of drivers, so often I end up with empty enclosures since I use the same drivers in different combinations across various projects. I have sold a few locally so far, but the market here in South Africa is too small to really be a viable option for this route.

I still can’t believe the low end I’m hearing over my headphones. I’m not usually a fan of listening to recordings of speakers, but this recording sounds amazing! I feel like there is little room echo. What microphone did you use to record these great-sounding speakers?

@SoundBlab 8 ай бұрын

Thanks. I used a Zoom H1 mounted to a tripod. Nothing complicated. Sometimes I will use two Behringer mics pointed at both speakers directly on axis, but its too much setup, so I am now only using the Zoom H1.
