Thiel 2.3 vs 2.4


I have 3.5's and love the deep bass.
I am tempted though to go with a newer and more modern speaker.
Im seeing some good deals on the 2.3's and Im wondering how much of a difference there is between the 2.3's and 2.4's
I have heard the 2.4's at Thiel and they are an incredible speaker!
I have become a devoted Thiel fan so please no other speaker recommendations.
My main concern is losing the deep bass of the 3.5's.
I understand the 2.3's only go down to 36hz or so.
Thanks in advance!

Irish65- The SS2 it was.
Go for the sub.
I could go on and on about the sub but you must (not)hear it yourself.It's a must have.

Shari is a straight shooter and rabid audiopihle.She knows good sound.
P.S. I'd love to take another trip to Lexington!
That Thiel room HAS to be experienced!
I live in NY but it was a beautiful drive.
Very nice state,'ol Kentucky! And the people there are all as pleasant as Shari!! :~)
How do those Thiel subs work? There is a very expensive outboard processor of some kind in their product line, but it's not clear to me if you need that to use their sub in a two-channel system.
