2 small subs or one big sub???

[chris661]

Hi all

I got 2x21L boxes, with 8" drivers in, with Linkwitz, goes to 28Hz@-3dB.

I would like to know if there are any advantages/disadvantages of 2x21L boxes vs 1x42L box.

Both will achieve same frequency response, but I tried the two boxes with full-range speakers on top, and it created a "bottomless" sound, I can't, however, recreate that sound by putting the two together. Is there a reason for this???

The boxes I mentioned above are just test boxes to see if the Linkwitz works, messing with placing them etc, before I build the proper thing.

Thanks in advance,

Chris

This has been discussed pretty extensively. There are vibration cancellation options with a single box, but there are placement optimization options for 2.
