SoundBlab Transmission Line Speaker Plans

[Rbertalotto]

I just bought the plans for the SoundBlab Tang Transmission Line speakers.....

https://soundblab.net/

Ordered all the Xover components and the drivers from Parts Express and a plunge router and bits from Amazon.

Will be building a Router Lift table for my old fixed base router......

Looking forward to see how good a full range speaker can sound....

similar plans for free

Hi Rbertalotto,



I had hesitated to do so myself, but then I rather went with a full DIY project based on the design of Bjorn Johannesen.
You can read my post <a href="!g6227027!full-range/88787-tabaq-tl-tang-band-post6227027.html">here</a>
A link to the plans is included.
I think the design by Bjorn Johannesen gives more bass with the driver.
Either way, you will also be very pleased with the TB W4 1337 SDF which has gread mids, and, what is less common, great heights !
Don't hesitate to experiment a bit with stuffing , after your speakers' break-in period .

Thank you for this lead, but I don't see a link to the plans.

Can you repost the plans link.

This one? Transmission Line Speaker – Build Plan | SoundBlab

It would be interesting to know what the inside of these exactly look like. Basically like this.

Just the picture shows at least 1 feature that suggests this line is “guessed” using classic design and not properly modeed and designed.

And 23 pages of drawings. I am pretty sure i know the general layout… end loaded, down and back up the top/back.

An elaborate set of drawings with notes & visuaizations would probably be 5 pages which does not say a lot about the authour's drawing skills.

Sorry for the downer, but TLs are often very misunderstood.

For a TB driver, i suggest, that the Tabaq TL is likely better thot out, and plans are free.

One thing about the plans from this site is that they are very detailed like a step by step build guide with links to every single piece of hardware or tool or supply possibly needed. Good for a total beginner who may not have all the tools handy. Price of $30 seems reasonable. I have not seen the plans but from website video seems well out together and substantial amount of documentation. Tabaq is great but I would discount someone else’s effort without actually seeing it.

 

[planet10]

End loaded, possiblly too small, the stand could certainly be eliminated, the plans might be very helpful, but if you are starting with a brick don’t expect it to go fast. It has all the classic earmarks of a “classic” design and as such is a non-starter for me.

$20 for plans is certainly in the standard range if reasinable pricing.

The plans are amazing and well worth the price. Fantastic photos and easy to follow.

Sorry the links got broken in the post, I hope this time it works better

Judging by its measured response, I'm not sure it rises to the [sub par] level of 'classic', though in room a pair might sound fine if the odd order room modes somewhat line up with its 'crater' dips.

Looking at the FR as well, we can see that the TL was not optimized for this driver.

 

[planet10]

Yes, one could get better bass with a simple reflex.

This driver is not a bass king. Still better bass extention. Tiny box.

It is a good folding geometry as it reduces the output of odd harmonics a lot as compared to the "3 fold" as per IMF and TDL

 

[planet10]

Huh?

At the frequencies the line works at it sees no bends.

But each fold, as long as sans deflectors, creates an expansion of the line acting as a high pass filter. Much more important in a horn with no damping.

Is that what you mean?

I would disagree on this one. I tried bass-reflex with the driver (simulation only), and never got it below 60 Hz. With the Tabaq design the box reaches down to 50 Hz, and the bass is cleaner (in my opinion).

Yes, MLTL does better and Dave suggested earlier that the TABAQ was likely a better choice, but we were talking about/referencing a simple BR was likely better also WRT the Sound Blab TL speaker.
