Hi all,
I'd like to built a small enclosure like a satellite speaker for my pair of w3-871sc because I don't need any bas,s I have a subwoofer for this purpose so Cyburgs and TABAQ are too big for me, where can I find a design like that?
Thank you in advance,

I use the very same drivers in a 70 cm high (28") small horn. It goes down to about 70 Hz, you still can use a subwoofer. If you want smaller, you can build them in a closed box of any convenient size.
Hi Oshifis,
Thank you foe your answer. This size still too big for my purpose (I want to move often the speakers from my house to my girlfriend house) so I think hte best option will be a sealed enclosure but I don't know how can I design it.
Thank you!

I have the W3-1364 in a 1.5 Liter Sealed Box. Your W3-871sc is quite similar. Should be able to work in a 1.5L to 4L sealed box.
Check out my post on the MICRO (W3-1364).

Hi Michael,
Thanks a lot for your desing it's really helpful for me.
What should be the difference (refering to the listening) between a 1.5L and a 4L sealed box? Less bass?

For your purpose, you could consider making a sealed box just a bit larger than the drivers themselves. The bass will smoothly roll off and you can dial in a subwoofer in the future to handle bass duty. I'd also consider aperiodic (just drill some small holes in the back of the box). Clearly you are not looking for optimal performance, but my experience with TB is that they work well in small sealed boxes.
The 4L box is optimal (ie Q=0.707). F3=131.8Hz
With a 1.5L box, there is 0.5dB hump in the mid-bass. More importantly, the increase in Q is not much. A slight increase in Q (from 0.707 to 0.855) for a reduction the box vol from 4L to 1.5L is a good trade-off.
Bass is only slightly less, from F3=131.8Hz to 136.5Hz. In practical terms, no difference.
You will need to support the W3 with your sub-woofer. The problem you will encounter is the mid-bass. Most active subs are designed for Home Theater use, hence they excel in the 40-30Hz region. When crossed at 125Hz, these subs have difficulty in producing clear, distinct mid-bass.

I was thinking also about that because I've found that the Logitech Z5500 has the TB w3-871sc in a very small satellite enclosure so I think it will work for me, I'm going to try to fin the specs of this enclosure.
Thank you for your help!
Inspired by this, i tried it out in a 1,5 l plastic bottle and a sock - it worked rather fine.
