This is the difference between the L5 and L7....after reading it, might wanna glance at the author of this passage...
"I have been asked the difference in these two woofers - so I asked and this is the answer I received. If you have more questions, I will get Polecat to answer - you hear that Tracy?
The new 2002 L5's are almost identical as the 2000/2001 model L7's. They have the same power handling, and specs as the old L7's. The only major difference is the L5 has a steel basket vs. a cast aluminum.
Now the new 2002 L7's have a few small motor changes, they have a new re-designed back brace, have better low bass output,new titanium injected cone, with a few mods to the cone, new cosmetics, new front/rear gasket for better sealing,wider surround for more Xmax than before, and a few smaller cosmetic items. So to boil it down, we needed to make a woofer that people could 'step' into from the Comp VR, but was better priced than the L7.
So the idea of a woofer that can share the Solobaric name, yet come in at a great value, the L5 was designed.
