I have tried several subs in my system. Original sub was a KEF HTB2SE wireless (the Minicooper wheel). That is one amazing sub but I wanted one that goes lower and has more power. I tried SVS SB16-Ultra, Bowers & Wilkins PV1D, Martin Logan Dynamo 1500x. Probably 90% two channel music thru Tidal and Spotify. 10% movies. Setup is in living room. Want all equipment to blend in with eclectic modern decor. I chose the Dynamo 1600x because it checks almost all of my boxes. I just wish they did these in a gloss piano black finish like the Dynamo 1500x gloss option. Don't get me wrong, the finish on the Dynamo 1600x is amazing. If this one didn't work out I was going to try a REL S-5 SHO. I have heard the RELs many times and I think I just want a little more power from my sub. Yes sometimes I like to really push the system. My search is done. I didn't think the 1600x would be so much better than the 1500x but it is. Much more tuneful and toneful, very very fast. The different connection options allow me to use modern and vintage amps and I can set it up for two channel and movies simultaneously The two apps work so well and are so easy to use I honestly feel like I have been cheated out of the process of setting up my sub. Just in case you are wondering why I didn't stick with the other subs I will explain now. The SVS SB16- Ultra was a little "out of control" at certain moments in movies and music. It would flap and flutter around. The Bowers & Wilkins PV1D is incredible. Surprisingly it goes very low and is visually stunning. It is like a Devialet Phantom without the extra tweeters and stuff. I just wanted more volume. The Dynamo 1500x in gloss is beautiful, sounds beautiful, and checked almost all of my boxes. The 1600x is more powerful, way more flexible and much easier to use and set up. I'm done, Thanks.
