RE: Seeking Advice - 20,1s, 3.7s, subs

Posted by Satie on December 16, 2016 at 13:15:48:
A more recent 20.1 will give you long life and musical prosperity. A post 2005 one should last an indeterminate time in excess of 20 year The older 20.1s start suffering from delam at 15 to 20 years or not at all, depending on how they were housed. Humidity control and protection from direct sunlight will do the trick to avoid delam.

The 20.1 is a true high end full range speaker and out details, out dynamics out bases and generally wipes the floor with the 3.x models. The push pull bass and midrange are a tremendous upgrade over the 3.x and that is complemented by a better tweeter as well. Having redone my Tympani IV with a push pull midrange I think just that alone does more than enough to justify moving up from a 3.x.

If your room and budget extend to one then a 20.1 is my choice. And by a clear margin. And I do think you would want to biamp before putting money into subs. DWM augmentation spreads out the bass nodes to provide more uniform bass. You will also want to enhance the frame with good bracing like Mye stands.

Another thing to consider if you can live with the sheer size of the thing and willing to do some DIY work is a magnepan Tympani IV or IVa with the mids replaced with a line array of BG Neo8 drivers and the crossover modified to accommodate the extra performance of the new mids - biamp is very necessary in this case. The big plus is having the mid/tweeter units in a separate frame from the bass panels so avoiding the IMD. 2nd is that the drivers can be time aligned which contributes remarkably to imaging. Then finally, the twin bass panels have a midbass impact that is quite unique to this design.
