Subwoofers

If foam surrounds on Rhythmik subs are an issue for you, why were they even on your list in the first place?  Also, I’ve never, ever heard of anyone having an issue with a Rhythmik sub.  Crossing Rhythmiks off your list simply due to foam surrounds would be a mistake I think given the performance, value, and overall quality on offer, but that’s me.

I have heard and owned a lot of subs and the JL Audio Fathom series are super deep and powerful.  

Honorable mention to the SVS SB3000 which are app adjustable, have excellent impact and a very likeable tone.  

I didn't see that model had foam surrounds, excuse me. 

Maybe it's me but I find Rhythmiks site hard to navigate.

Other than adding new products, I don't think they've updated their website in the many years I've been visiting it, but all the subs are listed on the front page.  Click on one to get the specs.  Not hard.

Check out the reviews (e.g. Audioholics) of the Arendal 1723, they have both ported and sealed versions.

I have the smaller 1961 sealed version in my 2.1 bedroom system.  It integrates easily with my Magnepans but still has plenty of oomph for movies and the like.
