Started new box....

[BetchaCantRide]

Well I finally got some materials, and started my sub box on sat. 3/4" MDF housing 2 Kappa Perfect 12.1's - ported. I'm still waiting to get the other sub, but once I do, I will begin breaking them in on the home system, and hopefully the box will be done soon. I've also been thinking about getting a new amp. Right now I'm running a MTX 2300. I'm looking into something higher end like Alpine or Zapco (maybe even USAmps or Mmats). Just felt like blabling....comments anyone?

why? if you do, remember that home systems are 8 ohms. car systems are usually 4 ohms.

I'm gonig to wire them in series.

As far as why break them in - I honestly can't tell you. It's just that I've never had a problem with any installs untill I met the Perfects. I've smoke 3 of em and people at sounddomain.com say the need to be broken in first. I don't want to play my system quietly for about a month to break them in, so I'm going to run them continuously on the home system for a couple days.

i agree with breaking in the subs. but you can do that in your car. i was just wondering why you were going to do it at home.

also, be careful you dont feed those subs too much power. the rated power is 350 watts. your best bet is giving them 300 watts. lots of people blown their perfects by giving them too much power. they dont need a lot of power to sound good.

I'm breaking them in at home becuase they need hours of play time to properly break in. Which translates into a lot of driving time while keeping the volume somewhat low. I know that once I get them in, I'll want to bump them pretty hard so to avoid temptation and let get get a good thourough break-in, I'm going to do it at home.

As far as the power issue, I've hear of people pushing power in the 500+ range to the perfects with no problems. Hell, the 3 I toasted was in a SEALED enclosure pushing a clean 150 watts to them. I really think their failure was do the the poor construction factor. If you look at the newer models (rubber ring around surround, different venting mesh), you will notice that Infinity finally beefed up the glue holding the coil to the spider - even still though, I'm gonna break them in just to be sure.

The new Kappa subs have been very durable for us at work. the biggest problem we have is the guys who buy the 100 x2 amp amp distort the hell out of the subs because they do not have enough power and melts the voice coil.
I have a guy with 2 Perfect 12s in a sealed box 1.15 cubic feet per being run by a Xtant 1001. He has had no problems with the new ones. He did have problems with the old one because the glue holding the surround would let go.

i thought 2 subs in one ported box kinda got offset, like one got more air then the other....... i have no idea what im talking about

lots of people have multiple subs in ported enclosures..

 

[RoadEnforcer]

yeah hence the no idea what im talking about part

Well I'm still waiting on my 2nd Perfect - I need to make sure I get a "new" one and not old stock. I'm really hoping the new ones are better than last years design. Anyway, about the common enclosure - they're are some issues you need to look at when doing the box design, but nothing major. The two main things are that the subs are getting the same signal - same amp, mono signal etc...and the other thing is the length of the wires (rca's, speaker). All wire runs need to be the same length to be sure that the signals are being reproduced at the same time.
