I just finished HENKJAN's design DESKTOP TL for the alpair 5, im using the ALPAIR 5 GREY.
I was able to finish it in 1 day, using glue and screw (its my first build and i want to take advantage of the holiday)
Its such wonderful sound. I feel no sub needed.
Thanks to HENKJAN & MARK

Hello Henkjan,
I was hoping that you would respond. I have a pair of Alpair 5, and would like to build your enclosure. However, my shelf is too short. Is there a way to make the enclosure shorter while keeping the bass output? Or am looking at a completely different design. Thanks.

how much shorter?
The shelf is about 30 cm tall or a little under a foot. I realize that a tl might not be possible. Have you built any other enclosures for the A5? Thanks.
so the max cab height would be just below 1 foot? how deep could it be? with a different 'fold' of the line, while keeping approx the same length and cross sections it will sound the same.
Depth is about 1 foot, so it would overhang the shelf quite a bit if the cross section and length remain the same. I was hoping that the length could be shortened and more stuffing added, but that might be a completely different design.
in theory lenght can be shortened by increasing the taper, but since it is already a strong taper I doubt if you'd gain much.
I was thinking more of a fold like this:
you could "play around" with MJK's allignment tables to see if you can make it fit somehow http://www.diyaudio.com/forums/full-range/163394-tl-alignment-tables-excel.html, maybe with a bit higher tune of the line you can make it fit.

well, its kind a embarrassing, no finish, just plain plywood and the alpair 5 not yet recessed mounted
but it still great sounding little beast
My speakers are plain particle board. Looks like sh*t but sounds very well
I think you should post a picture of them
just use the volume knob with care...Might have got this wrong, but isnt the Alpair 5 spiderless? I'm just wondering how it works in a TL.
No DC please
.. and don't act as silly as I did. While I was evaluating my preamp ( DIYHiFi.org • View topic - Preamp for BSC and fs notch filtering ) for these speakers, I wanted to know how it sounds on a NAD 306. I had bad luck and ripped off one power supply rail of my breadboard. The resulting DC offset went directly into a power amp fed by +- 70 volts... ... a little bit too much for the poor alpairs.. how long half a second can last...just use the volume knob with care...
but mine did not pass this unfair stress test. While the right one still seems quite happy, the other suffered heavily. Voice coil is still alive, but the cone now rests in a position that allows you to get an idea of xmax as well as of the polarity of the evil DC bump. Music is reproduced with 9db loss.
Interestingly I can still use it at very low volumes enjoying its typical sound, but anything louder than a heavy mouse click will cause distortions...
A new pair has been ordered. I never believed that DIY is cost effective
Of course I will put the NAD. Only my low power tube amp will be allowed to feed them...
