You came here to get some advice;
The JL is quite impressive. It's very well built, aesthetically beautiful, and the driver is top notch. However, as stated, there are higher performance-to-cost ratio subwoofers available,...even at the $2k range. Optimization of a subwoofer system to both the room, and the mains, is absolutely key, and facilitated much better with an eye on multiple subs, and some acoustic treatment. So regardless which avenue you pursue, be mindful about those items.
The BDP-95 is a tour-de-force without much competition. Even at $1.1k new, they possess killer value IMO. I own one, and it's blown me away from day one,...simply superb.
I've never had the pleasure of listening to ML loudspeakers for HT. There are those that would argue that they're best suited for music, and I'd agree. The conditions would need to be right for them to render a highly realistic HT experience. That said, anyone should have the good fortune to listen to a set of ML's properly set up and implemented for music. I've listened to essentially all their wonderful stat offerings all the way back to the beginning, 25-30 years ago. As recent as last year while attending Cedia, I spent several hours, all the way up until the show closed, listening to a variety of loudspeakers in the Sound Room section of the show floor. I heard Tannoy's killer 12" coax plain, black cube, install version. I listened extensively to Def Tech's, JBL's big room, Pro Audio Technology, Procella, all of these in well sorted out rooms with very high quality ancillary equipment. Yes, many of the HF drivers were compression drivers. But some of the finest, most well executed examples around. No one does the research and driver R&D that JBL does. Procella's mains are world class. Tannoy has been producing and refining coaxial compression drives for decades. The presentations were impressive.
I supply all this context because the last room I spent time in was Martin Logan. The show was an hour away from being entirely over, so the crowds were gone. I was the only attendee inside the ML sound room. They greeted me, we briefly chatted and they offered up some nice music as I took possession of the front/center money seat. The material started and I was slack jawed in dis-belief. This combo of McIntosh powered ML, me in the sweet spot, was one of the most pleasing, nice, musical listening sessions I'd ever participated in. Just simply smooth as silk, three dimensional image that was wonderfully detailed with not a bit of unwanted edge harshness or any perceivable issues whatsoever. The stark contrast to the admittedly killer demos in the other rooms was clearly evident, and 180 degrees out of phase. Yes, just what the doctor ordered, for sure.
Now, can a electo-stat system like that provide the best dynamic realism for HT? It be tough and depends on the conditions, such as room size, listening distance etc. I know one thing, I'd love to have a secondary, ... music only electro-stat system in just the right room. There are those that absolutely love their ML loudspeakers for HT, and I'm sure it would be very, very enjoyable.
Best of luck
