Default Compact Enclosures for Alpair 6M

The goal for these was the smallest size enclosure possible with at least a modicom of bass. Sims suggest <80 Hz (volume limited by size/excursion).

Neither of these have been built yet, The slot port version is the 1st cut at a nMar-Ken6M. drawn with 12mm material, good multiply recommended.

If it only goes to 80Hz, wouldn't it be better to leave it sealed and cross 1st order with a sub ?

Depends on the goals & needs. These do get you low enuff to XO to a sub.

If sealed a sub wouldn't do it, you'd need a pair of woofers. They should be excellent as a mid-tweeter.

Nice Dave! 80hz would make these excellent surrounds or even as mains in a smaller system. Very cool!

Looked at the sims again... 80 hz might be a bit optimistic, 70 Hz F10, slot port should get you a bit lower with a bit less bump than the round port. The uMar-Ken6 (which accomodates either A6P or A6M) is about 60% larger should get you to the magic 80. The full-size miniOnken for A6M looks like it will be based on 3.5-3.6 litre (still in development)

Chris is working on a set of sealed rear surrounds....less than a litre. To be used with (existing) Pensil7 LR & dMar-Ken7 centre

well, he's still looking at the drawing and brainstorming* the easiest way to fabricate an mirror imaged pair of enclosures with compound angles

I bet no nails and the 12" slider figure into it somehow

(*considering the remaining computational power, you'd only need a windbreaker )

BTW, an all Alp7 front row with dual woofer arrays, XO'd at 90Hz is is pretty nice little set up for a smallish (320sq ft) room

We built the big enclosure (3.6L) for the A6M. Works well.

320 sq ft is smallish?? Maybe in the North American continent , but most places elsewhere it would be considered largish I guess.

Edit: Probably we can lose the "ish" is largish
