Subwoofer for Tangband W3-871S

baxman · 26th January 2009, 03:31 PM

Hi all,
I am new to this forum, I hope you can understand my very poor English. I bught 2 tb W3-871S some days ago. I was very surprised how this small speakers sound. I was going to build a box with a side firing subwoofer (8'') and the tb mounted on the front panel.
It's a good idea? Suggestions?

Hello Baxman! I've built a pair of W3-871S monitors and I'm in the process of building an active sub/bass unit for them, based on a Tangband W8-740E 8" driver. Can't report on the results yet though, I'm afraid since it's not finished.

If you are listening to the raw drivers (not in any type of enclosure) they will always sound "small". In a proper enclosure, they will sound almost entirely different.

Take some time and learn a bit about the principles that define that "proper" enclosure. You will find that there are many approaches, none is necessarily more correct, but each is different. This is a good thing, as it allows you to pair driver and enclosure design to provide enhancement to desired properties and sometimes to minimize undesirable ones.

Hello,
thanks for you answers. I agree that a proper enclosure makes the loudspeaker sound in completely different way. I love the sound of fullranges, but I also like listen to the music "physically ", thing that I have never felt with any fullranges of contained dimensions.
My idea was to put together the two aspects.

I followed your suggestion and I mounted the tb in a little transmission line enclosure based on a project published on an Italian DIY review some years ago. Now it sounds in completely different way and I don't feel the necessity to add a subwoofer. I tried to make it play together with my subwoofer, but the sound loses magic.
I love it as it is now!
Thanks to all to have made to discover me this magic world of fullranges!

Hi Baxman,

Can you tell us more about the little transmission line enclosure based on a project published on an Italian DIY review some years ago.

Maybe the name of the enclosure.

Thanks,
Eric

Good to hear - fullranges can be really something very nice.

The project is on sale to the following address:

http://www.audiomaxitalia.com/kit/pr...ttproducts_pi1[backPID]=71&cHash=e20b6f1691

At the bottom of the page there is the link to the article of the review.

Hi Baxman,

Thank you for the link even though I do not understand Italian.

It looks like flat response to 100Hz and then drop quickly and you get 60Hz at -15db (if I read the text OK)

The Cybrgs Needle or Tabaq will give you more bass but of course a much bigger enclosure.

As anyone compare the Needle vs Tabaq ? My son's room has the Needle but maybe my daughter would be OK with the Tabaq...

Regards,
Eric

I can't say about the Tabaq, but I've compared Needles and BIBs. The BIBs won!
