Diamond Audio TDX 15's or Kicker L7's

I have already purchased 2 KX 1200.1 Kicker amps for my Expedition but am having a tough time deciding between 2 TDX 15d4's or 4 Kicker L7 12". The Kicker route would give them a rated 600 watts a sub, but some local shops have warned me about some reliabilty issues with the solo's. Either way I go it will be the same price. I know the L7's will get loud, but I want loud and tight. Plus the magnets on the TDX's are beautiful to say the least. Any help...?Pioneer DEH-P980BT, Zapco DCREF1000.4,Pioneer TS-C520PRS, Adire Extremis, MTX TA91002, TC Sounds TC-3000 15"

Magnets??what magnets. TDX's use a heatsink design. Personally i've never heard the L7's, but i have the Diamonds and they are amazing subs. Good sq and spl, will just eat up all the power you through at them. I run their CM3 series and i love them to death so i guess i'm biased towards Diamond stuff. Also depending on the box design, you ought to see about the transmission line ports on the Diamonds, it makes for a killer combination.

Well, I know there is a magnet inside the die-cast aluminum basket somewhere, so that was what I was refering to. I've heard great things about both subs fomr many people, but just nothing bad yet about the Diamonds. Thanks for the replys....Pioneer DEH-P980BT, Zapco DCREF1000.4,Pioneer TS-C520PRS, Adire Extremis, MTX TA91002, TC Sounds TC-3000 15"

Honestly, im not sure about the magnet on the TDX's. I was told that instead of the magnet surounding the voice coil like on most all speakers it was actually on the inside of the voice coil with the heat sinks on the outside surounding it. I dunno, they have some cutaway pics of them on Diamonds website. Either way they are top notch speakers.

The TDX's are much nicer than the L7's however if you want something that is loud tight and clean, I would check out the Eclipse http://www.eclipse-web.com/products/speaker/sw9100/sw9152.html Titanium series subs.

Tdsteele: From what I can tell from the website, it looks like the magnet and motor structure are one. They are, like you said, all inside the heat sink. Thats the part that I think look good. bberman1: I haven't heard the Eclipse subs yet. The only shop here in town that carries Eclipse usually only displays JL Audio, Diamond Audio, and some Virtual Technology subs. They look pretty mean though...Pioneer DEH-P980BT, Zapco DCREF1000.4,Pioneer TS-C520PRS, Adire Extremis, MTX TA91002, TC Sounds TC-3000 15"
