The 10" Deltalite goes with the SEOS-12, it was a typo because I was working on the page too late at night.
The newer designs are geared to fit better for dedicated home theater use. Lots of people ask if speaker 'X' will sound okay when used with speaker 'Y'. Or that they have plenty of room for width, but not the depth. Or what kind of stands do they need to hold a 75lb speaker.
So the goal for the new speakers:
One designer knocks out the whole line up and voices them to sound nearly the same. That way you can mix/match for center channels and surrounds without worrying about timbre matching. There will be an 8" and 6" model coming as well.
No one really complains about a speakers width, just the depth for theater use. So I wanted to do something shallow like the 88-Special but with a more traditional look using a single woofer. After drawing things up, the waveguide that was one size bigger than the woofer fit just fine and allowed for a very shallow speaker enclosure. The 12" model is about 9.75" deep. That's really shallow for a speaker than can do over 120db.
The speakers weight was very important on these. About 2 months ago a friend I know at a cabinet company went to some industry show and while there looked at different types of light weight MDF. He found a company selling a high grade MDF that was Carb 2 compliant and ultra light weight. These are the first kits to use it. The cabinet without the front baffle weighs......like 16 pounds. The baffle is cut from a very dense highly refined 1" thick material that is not light weight. It's the heaviest "mdf" I've used and think it's actually hdf. The 12" Deltalite woofer is super light weight and the entire speaker should come in somewhere around 33 pounds.
