<h3>Isobaric Subwoofer</h3>

This is a small, fully printable subwoofer <b>to be used in a 2.1 setup. e.g. with https://www.thingiverse.com/thing:4743037 </b> and is mainly intended to help overcome some of the limitations of printed full-range designs. In essence this is a 3 liter enclosure, which, thanks to the isobaric design, performs like a 6 liter enclosure.

Printed designs have a few <b>inherent limitations</b>. One is simply the size of what can be printed on a standard 3D printer (e.g. most back horn speakers you will find are rather room-filling, both in terms of sound as well as size), so all my horn speaker designs are very much down scaled versions of the "real" thing. Second is the material. Printed surfaces are very reflective (so add some damping) and although at high infill (approx. 60%+) their properties are similar to MDF you may not be keen on printing a large piece with 18 mm walls at 60%+ infill (this design has much thinner walls and I print at 20% infill / 3 wall lines). So yes, printed speaker enclosures are always a compromise and are best suited for use in 2.1 setups, which really helps with bass performance. Then again it is possible to print such beautiful designs (like folded horns), that would otherwise be extremely hard to implement.…
