The B3S is not balanced in the high end, and has a poor low end in the Needle. both the above are excelent drivers and suit the Needle very well.

Post #482 has this about the B3S.

The Tangband W3-871SC is available from Breitbandlautsprecher und mehr - SpectrumAudio at 20 Euros each and probably the same for the shipping.

I have tried the HiVi B3S in my TABAQ, and I can not reccomend this driver.
FYI, just finished a TABAQ cabinet with TB 4" driver, testing will be done during Easter. The T/S are different for TB 3 and 4 inch driver. By pure luck, the cabinet should work without any changes for both drivers. Looking forward to the direct comparison between the the two.

Over the past few weeks I have been contemplating buying some more drive units for my Needles, again :-)

And, as you do I have looked at other designs with 3" DU's and found in this thread the Tabaq which looks very good indeed.

My Needles are 830mm from floor to the centre of the DU's which is why I made them in the first place and why I like single driver speakers. I like to listen with the DU's at ear level when sitting, I think and this is just my personal opinion, that the stereo effect is at its greatest when DU's are at this height.

I also think that the port, and I maybe wrong about this, should also be close to the floor and if possible in a corner.

I now have my Needles in a corner in a 7 ft wide room and the increase in bass is noticeable over placement not near a wall or corner as in my previous setup.

Alas the Tabaq's DU's are 560mm from floor level and therefore well below ear level.

I think but am not sure about this, that if the Tabaq's were raised off the floor the corner effect would be lost.

I wonder if anyone has actually experienced this or anything similar.

Hi Jem
I have seen in the simulation that you will loose some bass response if you raise the cabinet from the floor. I know from others posts in this forum, that you can add some additional space at the bottom to make the TABAQ taller so the driver is in ear level.
This extra "box" in the botton is filled with dried sand.
The result skould be very good.

They still are without shoes, havent really decided on the size, they sound great for being so small, that frs8 isnt so bad as it looks.

Here goes:



Thanks guys!

Question

I like the looks of the speakers without the "shoes". Will leaving these out affect the sound quality much (and if so how)? I've tested them (on carpet) without the shoes and they sound pretty good to me.

so with the underside open? having a carpet close to the port would influence the low output somewhat I expect

Yes that's what I mean. I'm not an audio expert, but my guess was that the low frequency bass sounds that come from the underside would not be that much affected by carpet (or any other type of flooring). At least not as much as the mid- and high-tones. So that's why I'm thinking leaving the underside open would be ok.

easy to experiment I'd say. just try it on the carpet and then put some wood or other hard material under them

I've tried that and did not notice a clear difference. However because it takes some time to switch the material it was not easy comparing. Maybe I should test again, one speaker on wood, one on carpet, and switch speakers with the amplifier on mono.
