IA flatlyne still one of the better SQ subs out there?

380 for the ia

800ish for the ultimo

650ish for the w6

???? On the diyma these were a small batch if drivers made a few years ago for a select group of people but the show up used from time to time

The Dayton ho is another good one

Blues car audio has an Iso-10 that's pretty awesome but expensive

The hertz Mille sub is great as is the high energy

Arc audio black is good as well

Bad part about sq is its expensive

lol, w6's aren't that much anymore, around 300 give or take 50 bucks, thats more w7 price which is sql... man those are some good subs you guys are naming, wish i still had my w6s...

 
My suggestions,CDT Audio QES-1220

Diamond SX124 or Hex Pro HP12

JBL W12GTi-MkII

I'm considering sonic performance as well as power handling comparable to the Flatlyne.
That jbl is very nice I just don't like the dual 3ohm voice coils

And I was quoting new in store prices on the w6 if I could go to a local shop drop 350 on a w6 I'd have 3 10s in my car right now

 
Constructive recommendation?
Ignore rldriver he evidentially has no clue what this sub can do. The flatlyne is a very well put together sq sub. The only thing that makes it peaky is a bad box design

Ddtc has his dd9510s playing **** near flat and that's something most people would swear to be impossible.

If you want true sq go with that jbl above in an infinite baffle application. It will sound great and still take a good bit of power.

I wanted a pair of ia flatlyne 10s for a while but they stopped making them from what I understand and my ultimos are hard to beat sq wise.
