My subs went from BDR Cones to Nobsound spring to Townshend Pods. The last was a big jump with 5 subs but the difference was a surprise. Instead of the obvious improvement in bass that was expected the difference was immediately apparent even in music that seemed to have no real powerful low bass. The whole room opened up becoming larger, the speakers disappeared even more and the sound stage became even more enveloping. I think this is because when really low bass is done right you don't hear it so much as feel it, and this feeling is expressed in the sensation of being in a larger space. I know that sounds crazy but talking to others who have done Townshend under subs that is what they hear as well. I haven't touched the level on the subs yet at times it feels like they are turned down, until something happens and I realize no there is at least as much bass as before only cleaner now. So yeah you are missing something. Pods are cheaper than bars, I would try Pods if you can.
I can save you the trouble, REL will tell you their product is so perfect nothing can possibly ever be better, except their next one. 🤣 That is not a knock on REL. That is what they all say. No amp maker will ever tell you their amp needs a power cord or a fuse and no speaker maker will tell you to use a Podium, and caps? Forgetaboutit!🤣🤣
