Design my speakers!

from Alden, page 32

ideal box volume 15*Vas*[qts exponent 2.87]
yields 31 liters. Spec sheet for woofer , vented reads 60.

Win ISD...error after error...

There are data entry orders that make the software happy. And watch the units, too.

 

[SpeedyB]

Aha! thank you.

does not the SPL level in the above plot seem low?

Not familiar with BB, but, after comparing swan, HiVi, PE, etc data, my take is that the BB values needs a couple corrections. Also consistency-checked them and they're good enough for what we can know.

If you are more comfortable using datasheet values, use those linked/same as PE html page, not the old 2k12 pdf. Suggest to correct the Sd, etc in your BB data and see what you get.

 

[SpeedyB]

Thanks much,
I did not get anything done today.
I’ll get back on it tomorrow, which is today lol!

 

[SpeedyB]

I give up with Win Isd. followed the info in the AVR forum links. hit save. acted like it saved. then no file found

Hopefully this helps...

404 no exist

similar results to BB. at the Vb on data sheet.

something in the datasheet must be wrong.

 

[SpeedyB]

I will need to build a test box per Weems, etc
which is a good thing lol

 

[grindstone]

If this thing really is Fs around 28Hz, that's how these are. FWIW, here's a couple screens (micka and ISD) and an ISD data file to drop into the /drivers directory (sometimes write permissions are the issue).

Not sure how old-school you're going, but it can be a little easier these years if use REW with a jig. Personally, I think you should float offers for a sixie for somebody to chirp those drivers on their DATS laptop and be hours ahead

 

[SpeedyB]

Awesome, thank you very much for the Data file !!
Have DATS.
I ordered True Audio WinSpeakerz .
will see how that goes. Tried the demo version. seems nice.
Micka was actually giving similar results to BB pro. huge peak at resonance, with suggested box volume. In BB the suggested port was TINY lol!!

Tomorrow, I will make a 1cu ft test box.

 

[SpeedyB]

meant to comment earlier, those changes in the screen shot.. rather different to say the least! Awesome of you to provide!

 

[SpeedyB]

I used the HiVi data sheet

 

[SpeedyB]

Things r slow going at this time.
Several mini projects. Health issues.
Hope to respond as soon as possible

Aw ! Take care @SpeedyB... I don't know if you determined what you want to go for ?

In waiting - as an example of "Vintage Studio Monitor" - here is my personal take on a 3-Way enclosure, with 12" Woofer, 8" Midrange and "blade" Tweeter :

Feel free to ask if you want more construction details !

Definitely interested

 

[SpeedyB]

I’m now just waiting on the true audio software

 

[SpeedyB]

I am Baackkk LOLOL!

WinSpeakerz cd arrived.
Learning it, etc.

Liking what I see.
