Better 12's for a sealed box
Hi all, I have another problem for you guys. I'm the kid who has the
Trans am and was wondering about upgrading my current setup. I have 2 12" Sony xplod P5's in a sealed box with two seperate chambers measuring 1.75" a piece, and they're being powered by a Kenwood 9152D amp. I know that this setup should be pushing the subs a little past their RMS, but when I turn it up about half way, the speakers themselves are distorting. I am wondering if maybe I change my input sensitivity, if that will help with the distortion, or if I should look at a better pair of subs, and if that choice, what kind would be best with that amp? The main reason I got those subs were because I can actually hear down to 18 hertz, and the difference between the usual 25 and 18 Hz to me is huge. I have heard from many people that Elemental Design subs are good, but what are some others that: A) Won't distort when turned up B) Hit at least a 20Hz freq. and C) Don't cost $400 a piece Thanks |

one of the biggest issues you have is that 1.75 cubes per sub is a bit large for most 12's, which reduces mechanical power handling. you may be experiencing some of this here, or it may actually be clipping of the amp (volume at halfway does not determine amount of amp output, the gain on the amp in relation to input voltage does). not to mention those sonys probably don't sound overly great in the first place. but one thing to try would be to put some wooden blocks or something like that inside the enclosures to eat up some space and get the internal volume down to 1-1.25 cubes and see if that makes a difference. After the results of that test are in and you still want different subs.......I'd first stay away from ED due to shoddy business practices. secondly........maybe post a more precise budget and we'll go from there. ps- you can also mess with the gain a little if you want to satisfy your curiosity in that regard. another thing to do would be to turn off any bass boost, as that can distort subs before they normally would. -- KU40 |

Also, that's about the right size box to be ported, if you're not bent
on staying with a sealed setup.. A piece of 4" PVC about 16" long in each chamber will tune you down in the low-mid 30's. If you let them stick out of the box a little, thereby increasing your chamber volume, you can increase your LF a little bit more. |

Id never buy any Sony products in terms of subwoofers, speakers, or
amps. Sony trys to get there nose into everything and just make **** products. I believe all of their products are made with polypropalyneI, which in a broad sense is close to plastic. Polypropaline has been used in for about the past 10 years in speakers and now is outmatched with Polycarbonate, Kevlar, and even aluminum. Currently I have full alpine, probably the most heard of and respected when it comes to sound systems. If ur under a tight budget I'd go for Eclipse. They make good quality subs and components, but they dont bang quite as loud as my expectations reach for. Also, Kicker is a very well known company that have a patient on their square subs.. They're hot and a little more expensive than the Eclipse. |

KU,
Got me curious. I've not heard anything about eD's business practices. Can you elaborate?
