I have a logitech subwoofer....don't laugh

[GM]

Well, it could be used in one, but I was thinking more in terms of a simple inverse tapered pipe, though it too could be tapped like lilmike's TH.

Hi,

Fully agree with GM:

they did agree that they supplied W8-670C drivers for Z-560

Note: Normally people confuse this bass driver as used in Z-680, Z-2200 & Z-2300 with the Tang Band W8-670Q model.
Though both units look near identical, Z-2300’s bass driver is different from the W8-670Q in the rear section.
It became absolutely certain when my friend’s Z-2300 bass driver went dead and I have to personally contact TangBand via email to ask the model of the driver used in Z-2300 & its price. I also send them the above pictures of the driver to help them identify. To my surprise, they replied after inspecting the pictures sent to them, that this bass driver do not belong to them or in any way represent one of their models. But they did agree that they supplied W8-670C drivers for Z-560. So, you see Z-680, Z-2200 & Z-2300 are not TangBands. Prior, I was also the victim of this case.

Thanks guys...this is great.

Can you dumb it down a bit for me or point me toward the TL enclosure you were thinking of??

I might be keen to try such a project...

I was referring to one like bjorno's 3rd pair using the specs in the article you linked to, but hadn't time yet to do a sim: http://www.diyaudio.com/forums/atta...fer-dont-laugh-tangband_w8-670_c-versus-q.jpg

As you can see it has enough more low end to justify the size/effort plus once damped a bit should have better transient response.

I may need a crash course on what that link means...what would be the actual enclosure to be built?

 

[head_unit]

I had actually read that sealing the sub might make it go lower...I wonder where I read that???

Well, some speakers are ported up around 40 or 50 or 60 Hz. They die below that, because the wave from the inside can kinda leak out and cancel the wave from the front of the cone. Sealing those units might bring up very low stuff.

So, all I could hope to achieve is lower spl and higher bottom end? That doesn't seem like the best of trades...

What you gain is more faithful transient response & less ringing. How much that matters depends on your individual taste a lot.

as it stands now...I'm really happy with the sub. I think the Pioneer MCACC system is really quite helpful when setting up a theater room. When I had the sub up front under the center channel is sounded small...now that it's behind the couch, it sounds really big and smooth. I am almost wondering why I would need or want 2...yet, I will likely get another one.

Hi,

Your best bet is getting another one and not messing around with it.
Its likely EQ'd internally to suit the specific arrangement.
For $100 you can do a lot worse.

rgds, sreten.
