I am going to install a pair of CDT ES-02 mid/tweeter units in the doors of my 06 BMW 330ci. It will replace the existing pair of BSW mid/tweeters.
1) Does it have to be "sealed" in the rear as I have read ? Some say yes,
some say no. It looks like all that would be involved in sealing it would
be to attach and cement a 2" id plastic pipe cap or end. Is is that simple?
2) Can this be used without adding a tweeter ? Is lack of a tweeter glaringly evident ? It will be powered with either an ADS 50w x 2 or an Xtant b2100 (also 50 x 2) through a JBL MS8.
Anyone running these as both mid and tweet, and like it ?
