Thiel Owners

Don was an electrical engineer as is his son Dave, Michael's father.

Guys, can any of you help me with some basic information re the CS1.6?  I just bought a pair for the hot rod garage, but won't see them for a couple of weeks - I've never seen a pair. I need to know the dimensions of the slot / port. How wide is the slot and how deep from the inside / back to the start of the flare? Is the inside edge eased / rounded in any way? 

Any information would be helpful in developing some ideas around upgrading port performance. Thank you in advance.

From memory, the 1.6 front facing port is about 1.5” wide and maybe a foot tall. Probably about 2” thick and I’m going to guess the inside edge is square. Doesn’t seem like many 1.6 owners post here.

How wide is the slot and how deep from the inside / back to the start of the flare? Is the inside edge eased / rounded in any way?

The slot is about 1/2" wide x 12" long, inside the speaker there’s a about 1" thick x 2.5" height wooden wall around the slot (as port tube?), and yes it is rounded on the slot side.
Hope it help.

Thanks for the offer ;) but I'll stick with my Thiels - unless I decide to look for a pair of 2.4s/2.7s/3.7s. I still haven't made a decision because I haven't been able to get past the uncertainty of knowing how the newer models will sound with my current setup - which I see no reason for changing. 
I hadn't listened to speakers for many years but have recently been visiting some dealers to listen to newer models and hear for myself how speakers have changed in 21 years. Turns out I think my 3.6s are better (in what I look for in a speaker anyway) than just about all of the new speakers I've listened to -- and that's in spite of all the sales gimmicks and "creative marketing" which unfortunately is still very much alive and well among too many high-end dealers. 
What I've learned in my travels: there are tons of speakers out there, but very few that are really worthy of serious consideration, and-after price is factored in-Thiels were and still are unique in combining value and excellent performance. Other speakers just "don't sound right." 
Who would've known that I'd have made such a good purchase decision over 30 years ago when I bought my first pair of  03a's.
