Posted March 29, 201114 yr I was going to get a DCON 12, ported around 30-32hz. I plan to run it off the bridged rear channels of a 4 channel amp. Was going to get the Crescendo 1000C4, but it doesnt have the option to use the HPF as a subsonic filter. Will it really be needed? I like to listen to Bass Mekanik and other artificial bass heavy stuff like that.
March 29, 201114 yr You need a SSF .... you will damage your speaker fairly quickly if you don't.. Without the filter you will end up playing notes lower than your tuning and that will damage the Dcon..
March 29, 201114 yr If you're going to port the box at that frequency you really should run a SSF. Is it necessary? No of course it isn't. I personally would never run a ported enclosure without a properly set SSF. How low does the HPF go on the Crescendo?
March 29, 201114 yr specifically because he mentioned "artificial bass" tracks I will go ahead and say YES.. he needs to have a SSF in place... Otherwise go sealed with a second Dcon???

March 29, 201114 yr Well it seems as if he hasn't chosen his amp yet so I would go ahead and say either choose a different amplifier or get a stand-alone filter.
March 29, 201114 yr Well it seems as if he hasn't chosen his amp yet so I would go ahead and say either choose a different amplifier or get a stand-alone filter.Yes very true... OP, are you looking to save money, or space, or both??? Using the rear channels of a 4 channel amplifier is not a bad idea but going ported is for that particular setup...
March 29, 201114 yr Author I have a DSC-480 left from the setup I had. Was going to sell it too and just get a single amp to save space and money, and make it easier. Wouldnt really want to spend over $200, other wise Id just keep the DSC-480 and get a mono amp. I had two SA-10s and a ZRS-C65, but sold them to pocket a little bit of money and not take up as much room. Normally I wouldnt have even asked about the SSF, as I know its good to have. But I remembered when I had my RE SE 12, I didnt have a SSF on the amp, and it was ported, and never had any issues. The HPF on the Crescendo is 60Hz, so no way that will work as one. I also was looking at the Hifonics ZXI-150.4. No idea if it does rated or not, or if its a good or bad amp, but its about $200 shipped, same as the Crescendo.150 x 4 @ 4300 x 4 @ 2600 x 2 @ 4rated @ 14.4v3x40 amp fuese, HPF 10hz-15khz 12db octave (can be used as subsonic filter, high enough to cross for active if I wanted to later on), LPF 30hz-150hz 12db octave
March 30, 201114 yr Author low pass on the amp and high pass on the hu? sort of like a ghetto bandpassSub out only has a LPF on my HU.
March 30, 201114 yr crap2 of these could workhttp://cgi.ebay.com/US-Acoustics-USX-2150-amplifier-/180641112122?pt=Car_Amplifiers&hash=item2a0f0ca03a1 would give u 150 x 2 for your comps and the other would give u 450 x 1 bridged
March 30, 201114 yr Author Whole point is to save space by running a smaller sub box and one amp.Thanks though.I think Im just going to keep my DSC-480 for now, since it has a SSF. 70 to my comps, 300 to the sub untill I want more or it dies.
April 11, 201114 yr I'm very glad that stumbled upon this thread because I'm in the same boat. I already bought the crescendo 1000c4 and I was thinking of using two channels for components and the other two channels bridged for a 10" DCON but after seeing this thread I'm a bit skeptical about getting the DCON. I wanted to build 1.0 cu ft box and tune it to 30. I did some research and some people say you need the SSF and others say you don't need it because most regular music doesn't have crazy lows that can damage a sub. I listen to rap(Eminem), dubstep, some pop and rock. I will most likely keep my gains down because my car has a 70 amp alternator. Will a DCON get damaged in my situation? Thanks in advance.

April 14, 201114 yr Will a DCON get damaged in my situation? Will one get damaged?maybeCould one get damaged?Yes
April 17, 201114 yr Will a DCON get damaged in my situation? Will one get damaged?maybeCould one get damaged?YesThanks for the reply. I guess I'm gonna have to stick to sealed enclosures.
April 19, 201114 yr Look for external subsonic filters. It's cheap, small, and efficient for your sub. Maybe parts-express or madisound.com have some. Take a look there. It's too cheap to run a sealed box and loose output !A 4 ch for sub and speakers is a good idea if you don't want big power.
