^^^^^ I love the CDT es-6 mids, but they lack midbass vs focal or ID or even some raw driver like Aurum Cantus,Scan Speak,SEAS, even Dayton
The tonality of the es-6 is one of best i have heard.
SQL is subjective.
If i where to buy a good comp set i would look into Helix,Hertz,maybe HAT.
Morel & Dynaudio is hard to beat as well..
Placement,aiming,tuning,deadening will play a great or even greater part in your sound stage.
What amp will you be using???
Massive audio has been getting great reviews lately.
Please stay away from Rockford lower to middle line of speakers.
What type of music do you listen too???
oh Rainbow higher line of speakers are great, but well above your budget.
Are you adding a sub???
