Default who can make a flat pack for Alpair 10.3 ?

Hi, I'm looking to make this design for the Alpair 10.3

"Erich's Hartmann's bookshelf box"

which can be found here
Alpair 10 Gold | Markaudio

I don't have the tools / space / expertise to make it myself so I'd like to hopefully but a flact pack of it premade.

can anyone point me to where I could obtain one ?

Thanks

Where are you located? Iíd be happy to make you a flat pack, but preferably if youíre local. Mainly because I think shipping wouldnít be very affordable.

I donít have a CNC machine but I can definitely cut a sheet using my tools and test fit the assembly before delivering.

Would you like Baltic birch plywood, MDF or something else?

Regardless, Iíd use a different approach than the design for the back relief on the speaker. It would be a 45deg bevel instead of just 20deg. The 45deg bevel would be applied all around, except where the driver screws are located for support. Thatís similar to what is employed on the frugal horn.

Hi anorphirth,

Not sure that the Eric Hartmann bookshelf is optimized for the Alpair 10.3, and it was originally designed for the older Alpair 10.2 driver.

More info here:

Compilation of Alpair 10.3 designs

P10 might have an updated design with same dimensions:

Bumping this thread. I'm also looking for a flat pack or preferably a premade bookshelf cabinet for an Alpair 10p. I know there are flat packs for floorstanding cabinets available from the UK, but these exceed my budget and size constraints (small NYC apartment). Any ideas?

I also don't have the space, but i know a company that supplies good wood and cuts the wood for me. I give the designs in pdf or audocad format and they cut it clean with an CNC exact right. You should probally do the same where you live.

My own designed subs (big oldskool ported speakers) costed me 150Ä for the wood (18mm MDF) and the cutting for 2 speakers, so it's not that expensive over here in Belgium. I just had to assemble them, paint them and add the driver and so...

I made this design a few times, first for myself (and used it in a small appartment for years) and also for a few others who were very pleased with it. It's very good sounding (especially powered with a tube amp), only the bass is a bit vague and undefined (but very good for a 6.5" FR speaker). I now still use mine, but in combination with a big subwoofer with an 10 Scanspeak driver and a 1st order CR at 180Hz

It's designed for a german company who sells all the stuff needed but the wood as a kit:

Mark 4

As you are in NY, it's probally better to source the components where you live as importing it from Germany will be expensive.

You can check with Planet10.

AFAIK he does flat-packs of a few designs and from time to time has a few finished items in stock too.

Scott has a simple bookshelf design for the 10p that works excellently. I used it recently until switching into Pensils, and i was amazed at how good a job they did with the 10p.


Bass reflex standmounts 10.3 / 10P


I had a local carpenter make the cuts for me, costing the equivalent of $120 (18mm BB ply). I glued them up myself which was easy enough. If you have a carpenter local to you he might also help out with routing for the driver.

Zia - Dave may have a few flatlaks left in stock for smaller MA and Fostex drivers, and certainly some fully assembled speakers - mostly with drivers included- Just too much stuff, almost giving it away, part 4 , but is no longer in a position to produce new kits.

There are more than enough enclosure designs for these drivers that would be fairly simple builds, and while when building speakers I certainly took advantage of a CNC for rebating driver cutouts and non rectilinear cuts, many of those designs require no more elaborate woodworking equipment than a well equipped table saw and hole cutting router jig.

Iíd definitely suggest that high quality plywood - Baltic Birch, etc - should be considered essential for such a build. Due to the combination of thick frame and shallow cone profile, the original Alpair series require both rebating of driver cut-out for flush mounting, as well as chamfering of rear side of opening. The Pluvia, and new MS models have a much thinner frame - designed to eliminate need for rebate - and more open basket leg design, but even shallower cone profile so they still need the rear of cut out to be chamfered.

Lastly, to repeat what Iíve said many times before, given the availability of (floor)space, Iíd generally choose a floorstander such as Scottís Pensils or straightline MLTLs over a bookshelf/ standmount design for the same driver. The difference in material costs between the two would likely be less than that of a decent pair of stands, the net amount floorspace required would be the same, and unless poorly designed/built, the larger enclosure should deliver better bass extension and dynamics. Of course, there are numerous exceptions to that rule - Iím currently running systems with three - a very nearfield computer desktop, and centre channel & perimeter surrounds in a 7.1 HT system. Then thereís the ďSub/SatĒ modular concept, with small enclosure operating anywhere from low 100ís Hz on up, supported by separate woofer/s - either mono or stereo, depending on chosen XO frequency.
