Small desktop TQWT speaker with TB W3-871SC

[Flops]

Hello diyaudio community,

I had an idea for a small desktop speaker which should work using the TQWT principle:

An externally hosted image should be here but it was not working when we last tested it.

What do you think, will it sound ok?

Technical stuff:
The pipe is nearly 70cm long so it should amplify 122 Hz. I want to get a little bit of bass out of it but I have no idea how I can make the pipe longer without over complicating things.
The slot is 3x100x30mm, is this alright?
I plan using the TangBand W3-871SC.
Is it possible to simulate the enclosure before building it (I'm on a mac)?

Thanks in advance

To simulate it you'll need the MJK worksheets. The MathCAD to run them only works in Windoz. I have yet to see if it will run in CrossOver Mac, but if i have to i do own WinXP and VirtualBox is free (althou Parallels is a lot slicker).

Thanks, I will simulate it later and post the results (I can probably borrow my brother's latptop and use windows nonetheless).

Is it possible to use Akabak or ABEC2 to simulate my speaker design? I don't want to spend money on MathCAD, yet.

I just did my first simulation using AkAbak, here is what I did:

Can someone check if I did everything right? Here are the TSP of the TangBand: http://www.tb-speaker.com/detail/1208_03/w3-871sc.htm

Shall I add more parameters?

Thanks in advance
