Venatus 2 Report post Posted March 13, 2008 (edited) Are you actually able to buy grills for subs, I like to actually use my boot, and dont want anything ramming through the cone accidentally. At the moment I just have a ghetto as one, made from some auto mesh that was lying around and a coathanger. Its fairly strong though... I cant notice any difference, but does anyone reckon it would effect the sound having bits of wire right in front of the cone?

3 SERIES 93 Report post Posted March 13, 2008 Yip, you can get grills for subs. Just do a search on the net for the type of sub you have. Im getting a nice Alpine 10" one for mine for the same reason. Quote Share this post Link to post Share on other sites
Venatus 2 Report post Posted March 13, 2008 Sweet, yeah I found a few but theyre all overseas so Id have to pay shipping. Thus the ghetto one can stay for a while Quote Share this post Link to post Share on other sites
3 SERIES 93 Report post Posted March 13, 2008 ha ha, fair enough. Buying stuff off ebay is good at the moment as the US dollar is pretty close to ours. Wont cost that much! Quote Share this post Link to post Share on other sites

Remember to watch the polarisation of the wire, and take into account the magnetic deviation for where you live By aligning the magnetic polarity, the free-space particles excited by the subwoofer will be enhanced, rather than degraded, by the faraday-effect of the grill as they pass through. You can also improve you performance by de-magnetizing the tyres : "Magnetic fields emanate from radial tires due to the presence of reinforcing belts which are made of magnetized steel wire. When these tires spin, they generate alternating magnetic fields of extremely low frequency (ELF), usually below 20 Hz. " So you can see the negative effect the magnetised tyres will have on the subwoofer performance To avoid these problems, use non-metallic grill material, and ensure the immediate surrounding area (ie: within 1/8 of a wavelength @ 50Hz) contains no magnetic materials. You can effectively achieve this by mounting the subwoofer on a fibreglass boat anchored 10kms of Rangitoto Island ... :-) Quote Share this post Link to post Share on other sites
Neal 545 Report post Posted March 14, 2008 (edited) Try http://www.jaycar.co.nz for your sub grills. The key is to have a fairly open weave , or just at more power. Edited March 14, 2008 by Neal Quote Share this post Link to post Share on other sites
