mmm... Didnt know DLS Iridiums are priced at 1.5k or so...
MS6 at 1.5k is a bit high... was quoted closer to 1.2k previously.
Alpines 177A's are also about that price...
other options u can try CDT CL's at abt 1k (got 1 set 2nd hand for sale)
Personally I dun like Focals... Tweeter a bit too sharp to my liking... MidBass good tho
MBQ even worse than Focal... not my thing
Dyns are nice but have high power requirement so big big amp need to be installed
I kinda like the Helix cuz for the price I get it at its really a bargain... normal shop price will be much mroe than this... Just go ask how much an A4 competition amp is these days.. :) Once I am free I will install a full Helix setup for demo purposes.
Additionally, before we continue on.. whats the total budget you are looking at? This way we can help recommend stuff to you to meet your budget rather than recommendign 10,15,20k amps and speakers...
