Default New 3" Full range TL

Hi All,
I follow this fantastic forum from many years
Now I would like to realize a new project with yours help

Frome some years I have two full-range speaker made with the TB W3-871 loaded in DCAAV, these are the speakers dimensions's and the simulation:

Click the image to open in full size.

I am very happy from the results.

Now I would like to realize another two monovia but loaded in trasmission line/back loaded horn. First to try another type of load and second to take better care of the design/color of the speakers.

I'am thinking about somethings like this:

Click the image to open in full size.

The speakers shuold be for a desk, therefore the speakers dimension of the previous image, 400x235x100, should be OK, but not bigger.

Now, the budget for the speakers is not too high, therefore I don't know if remain on the w3-871 or another driver like this.
3" or 4"?
Can you suggest me some speakers in the same price range of the W3-871?

I'am trying to understand how works hornesp to simulate this type of load, have you any guide or tips to start the simulation?

I prefer to simulate and realize my own project, though maybe works worst than other projects

Excuse my bad english, but it is not my first language

Thank you very much in advance for your time and help!!

Some little questions

For the Hornesp simulation, I choose:
- Quarter Space
- Loudspeaker type: Horn loaded
- Horn Load:
At this point there are the first problems, I don't know these types of loads
I think that I should choice, in my case, beetwen Back loaded or Offset Driver. Now, Which are the differences?

- Number of segments: Also in this case, How I can choiche the number of segments?
- Flare profile: I think that the conical is the most easyest to built, therefore I will choose this.
- Throat Chamber, Thoart Adaptor: What are?

Thank you very much

Doing a little TL is difficult (TLs tend to be big). Have a look at teh Woden Baby Labs for inspiration.

Little “horns”, as you have shown, are really just badly designed TLs — they are not big enuff to supply any real horn load.

I put my W3-871 into a 1.5 litre sealed box.

A folded TABAQ is another possible candidate.

Hi Dave,
Thank you very much for the information.

Could you please explain me the differences between the transmission line and the horns?

I search in internet but i don't find what is the TABAQ. It is a mass loaded transmmission line?

Ale

If you want to try an easy to make and fun back loaded horn with a 3in driver, try a Cornu made of foam core.

Ever think of building a Cornu Spiral horn? Now you can!

For 3in driver scale plans down to 20in to 24in x 2.5in to 3.5in deep. The little W3-871 will probably work in a 20inx20in x 2.5in deep Cornu. It is a a fun speaker.

For a TL, try a 5in driver - in something like this:
Low-Cost PMC-inspired TL Monitor with DC130A and DC28F

Best to do a simulation though.

Hiii xrk971,
Thank you for the information. The Cornu Spiral Horn seems to be funny but very very ugly xD Probabile the WAF (Wife acceptance factor) is -inf. ehehehe.

I think that whit a 5in driver the speaker become too large for a desk

EDIT:
I have do some simulation with a the W3-871SC, this is the result:

Click the image to open in full size. Click the image to open in full size. Click the image to open in full size.

I think that I can put this TL with mass-load in a box of dimensions arround the desidered max value.
What do you think about this simulation?

Thank you again

Try a 0.40x scale Karlsonator with 3.5in TC9FD or 3FE25 or PS95-8. Its a folded mass loade TQWT TL with an acoustic lens. Great desktop size and sound is wonderful.

It’s the white box in photo.

Thank you, I will read the thread!
In the previous post I add a simulation, what do you think about it?

The bass peak to too sharp - try rolling it off slower and less peaky. Take a standard Tabaq MLTL as your starting geometry and go from there. I think your volume is too small for the driver's Vas and the tuning too high so it is peaky. Try increasing vol/length and lenght of vent. If you want a compact TL, pick a driver with a powerful motor (Qts in mid 0.35 range), and smaller Vas. Only one in 3.5in range that comes to mind is Scanspeak 10F/8424, Faital 3FE22, or FR88EX. But tune them to maybe 75Hz. They won't go deep like a moderate Qts 3.5in driver in a MLTL but will sound cleaner in a tapered TL.

What do you intend with Standard Tabaq MTLT geometry?
I try with another driver!

Thank you very much!
