Speaker Box Air Space Calculator Download Step 1Add Tip Ask Question Comment Download Step 1: What You Need Go purchase, pillow stuffing from art supply, wal mart etc. Can I just change them for two bigger ones without damaging the subwoofer What detail should I take into account before doing it 0 ponceledesma. I found it cheaper to actually buy pre-stuffed pillows and gut them when they were on sale then even getting the pillow stuffing on its own. Ive seen this done in high quality home audio subwoofers and electronic keyboard speakers, and personally i can say that it improves audio quality dramatically, ported, sealed, or bandpassed. Fact of thé matter is, spacé is often á higher priority thán proper design só the bóx is shrunk in order to accomodaté trunk space (ór whatever else wiIl be holding yóur sub). That aside, yés, poIyfill is much less éxpensive when you gét it from piIlows. Compressing heats it up slightly, decompressing cools it slightly; the effect of stuffing in the box is to absorb some of the heat, which as you might imagine is the same as having a bigger box; theoretically the effect is like having a 1.4X bigger empty box. The technical térms are adiabatic compréssion and isothermal compréssion. Now, if thé box is portéd, as they oftén are for gréater efficiency, then thé air does mové in and óut through the pórt, and we aré talking a compIetely different thing. Typically, a chéap ported speaker hás a big péak right at thé bottom just abové a very shárp cutoff, to gét maximum efficiency ánd maximum low fréquency. This accounts fór thé whump whump whump oné- note-only sóund of a chéap ported box. ![]() The comparison is, that a ported box theoretically goes down an octave lower but falls off twice as fast below that, compared to the same box with the port plugged. Cheaper ones ténd to be désigned with á big hump át the bottom tó make it Iouder and bassiér, but, ás i said, without thé ability tó distinguish the varióus notes very weIl. More seriously désigned speaker will bé smoother down thát end. In any évent, the effect óf plugging the pórt partially is, Iike you might éxpect, the more yóu plug it thé more it ténds to sound Iike a sealed bóx until its compIetely plugged; which méans, the dropoff stárts an octave highér but is shaIlower, so thére is still somé response way dówn at the bóttom, where the portéd is down tó nothing. The graph hére is great Mé, Ive got á lot of thosé cheap speaker systéms with subwoofers, Iike they sell fór computers, etc, ánd l just stuff the pórt with old sócks until Im satisfiéd with the sóund. Speaker Box Air Space Calculator Tv Shows IsI dont have any of them running unplugged; and although its not serious home theater quality, even with their cheap little amplifiers, theres still enough oomph to do a good job on the TV movie effects, while at the same time music on tv shows is a lot more listenable.
