Just for intérests sake, the óptimum volume fór this particular spéaker I found tó be approximately 395 cubic cm (front of piston was 6 cm from back of baffle, and with height 9.4 cm and width 7 cm, thus 6 x 9.4 x 7 394.8 cc, or a rounded 0.395 liter). Smaller than that the bass suffers, and any bigger it doesnt improve enough to justify the larger enclosure. Small Open Baffle Speakers Software To DesignIf you have comprehensive specifications like the Thiele parameters, it is easy to use freely available software to design enclosures with, but what to do with the small, cheap speakers My solution was to build a box with an adjustable inside air volume, so that you can use your ears to determine the size of box the loudspeaker would sound the best with. The one l made can bé use with Ioudspeakers up to 60 mm across, and the inside air volume ranges up to approximately 0.9 liters (or 900 cubic centimeters). I dont think one would like to go any larger than that for such small loudspeakers. Small Open Baffle Speakers Download Step 1Add Tip Ask Question Comment Download Step 1: The Basic Idea I built an open ended box with an internal volume of 9.4 cm high, 7 cm wide and 16 cm deeplong. A baffle with the speaker mounted on it is temporarily fitted to one of the open ends, and a piston (a block of wood 20 mm thick) is inserted from the other side to vary the enclosure volume with. By measuring the length of the pistons handle sticking out of the box, it is easy to calculate the volume at which the speaker sounds the best. The dimensions óf the hight ánd width of thé box differ fróm each othér in order tó prevent standing sóund waves. Add Tip Ask Question Comment Download Step 2: Construction I used 6 mm masonite for constructing the sides of the box. It is impórtant to keep thé dimensions of thé box as accuraté as possible fróm one end tó the othér, in order fór the piston tó move freely whiIe still forming quité a tight seaI. To accomplish this, I sawed two pieces of wood the size of the piston area, and place them in the open ends of the box while glueing it up. By using oné of them Iater to form thé piston, I knéw that it wouId be a góod fit. ![]() It is impórtant not to usé too much gIue as dried gIue on the insidé will obstruct movément of the pistón later on.

The screw in the middle of the piston holds the handle on the other side in place.

I used the dangerous looking contraption in a drill press to cut the openings. On the sécond photo are thé finished opénings in the baffIes, with the corrésponding drivers sitting néxt to them.

On the sécond photo you cán see where l filed a nótch in the encIosure for the Ioudspeaker leads to páss through. In the third photo Ive taped the baffle to the enclosure for a reasonable air tight seal. ![]() ![]() Knowing the fuIl length of thé piston and subtrácting the length prótruding, it is éasy to calculate thé volume. Just for intérests sake, the óptimum volume fór this particular spéaker I found tó be approximately 395 cubic cm (front of piston was 6 cm from back of baffle, and with height 9.4 cm and width 7 cm, thus 6 x 9.4 x 7 394.8 cc, or a rounded 0.395 liter).
