Thanks for explaining thing in layman terms. Rythmik was on my short list...hence my curiosity when I heard about the upcoming 18" designs.

Unfortunately...a single sealed 18"...was not in the plan at this time....so I had to focus on those mfg who offer the compact design I need for my current needs.

I'd like to experience a Rythmik product one day...in hindsight...I could have waited I suppose, given the current delays, not sure on when the new 18" will be coming out.

Unfortunately, most of the local folks I know are into DIY designs.... thankfully...I have not gone down that rabbit hole, nor do I have any future plans in doing so.
