the 315 has for my ears too much highs, too sharp. good detail, but I can't listen to them for more than 15 minutes.
thanks Henkjan, is your tabaq already broken in? or you just started to listen to it, im thinking it needs hours or days of playing to break in. Or i'll just consider the W3-871S .

I listened to the 315's in the Lancetta for a couple of days, nothing changed in it's benefit.

The W3-871 really improves during the first ~5 CD's, especially the highs.

"My observation is on the stuffing. Doesn't such quantity muffle"

I tried the speakers without stuffing and the bass output went down to my ears. Also they were peaky sounding. Using the stuffing appeared to me to bring back the bass and smoothed out the response. I know what you mean about the stuffing "muffling" as my 1st project was the Cyburg Needles (with the W3 871's) which I originally had put to much stuffing in, and that did attenuate the sound to the point of making them sound nasally. After lightening up the stuffed front chamber the sound improved dramatically. On TABAQ I have left the top unglued (weighted down presently), so I can adjust the stuffing if necessary (I did weigh it as close as I could get to .23 lbs.).

"I have done som simulations to see if I could make a taller version of TABAQ, but has no solution yet."

Bjorn, where do the simulations show alterations in the TABAQ's performance when they are made taller, or the port raised up from the floor? Just curious. At some point I will get the software and equipment necessary, to measure these responses, however, presently measurements will be made subjectively with our older ears (wife and I) and younger family members when they visit.

In addition, the sand in the false bottom seems to be necessary, as bass response was less and more cabinet resonance was noticed when the chamber was left empty (cabinet clamped up for subjective test).

I hope to have the speakers inside (presently in my garage) today and will post some impressions.

Jon

Jon, I am still playing with this idea and would build a sample first.

I've gotten a lot of satisfaction from my FE127e MLTL build.

You mention the port desing as integral. I've found (and it's just
personal preference apparently) that an exterior down firing port
gives the best bass on small drivers. So wit the false bottom to adapt to ear heigh, what dims for a round PVC or plastic port would
work in this design? From reading what I could understand of Martin King, the terminus moves no air and the dispersion pattern is radial at the terminus or horn mouth. This, to me says a port constructed on the vertical will give port frequencies in the horizontal plane. This may be why I like it. Being a rank amatuer concerning theory, I'd enjoy hearing opinions on this.

Can you give the dims for a round port?

This is the best-easybuilt speaker with Tangband W3-871 or
like mine W4-1320!

Excuse my ignorance here - but would putting in the larger driver mean the dimms need to be changed? For example, the front of the speaker is only 10mm wide - same as the driver.

Cheers

Nickel, i started with the W3-871 and then just enlarged the hole
to fit the W4-1320, its tight but it works.
Nothing else need to be changed.

Hi Solve - that's a great looking speaker. I've just read Post #1 again - the attachment, and now see that no changes are required.

Many thanks

Hi Solve. How is the high frequency response of the 1320s? Do you feel the need for a tweeter?

G, there is no need for an tweeter.
The sound is very similar to W3-871 except that
here you have the bas!
Very good sound
I run it true an an cheap Matsui DVD player with DAC in the box
and AMP 6 Basic.
Im very satisfied!!
