Rhythmik lv12m experience vs RSL 10smk2

Well... the ongoing subwoofer saga, sigh. A couple months ago I introduced a Rhythmik lv12m, a 12" ported model, that is in place of my (beloved, as you may know if you've seen my other praises of it) RSL 10s mk2. I've had the Rhyth in there for a couple months now, after becoming persuaded by reviews and forums that it would be superior to the RSL, particularly in the lower reaches... not that I really felt deprived by the 10s, but hey if you can have it all...

OK, so here's where I'm at: yeah, the Ryth gets down lower. A little bit. But I'm not sure I care, yet. I've been using the peq, and my REW w Umik, trying all sorts of settings, from flat to rolled off to... well you get the drift. I still can't get it to integrate as well as the RSL 10s mk2, w my Q Acoustics Concept 50 mains; the 10s was effortless in that regard. And, the Rhyth doesn't sound as dynamic, or "quick," and impactful without over-heaviness, as the RSL. And, with video/movies, the Rhyth declarifies vocal dialogue, unlike the RSL which clarified that critical range. And finally, and here's really what motivated me to instigate this thread:

I was cranking Boston's first album while lifting weights in my listening/living suite... and I'll be damned if I didn't detect what I think might have been port noise or port distortion (or something) with the Rhyth. I'm only measuring about 88 db or so, give or take, so that shouldn't be too tough to handle. No matter how I cranked the RSL 10s, I never heard anything that I even suspected was port noise, and in fact hardly even knew the RSL was there at all other than the impact it was providing as it just disappears.

What's going on here? Is it really possible that I'm hearing some sort of port noise from the Rhythmik? And, would that also explain why it still won't integrate as seamlessly and even be occasionally localizable, which was never a problem with the RSL?

If so, that'd be the nail in the coffin for that Rhythmik model, and back to the trusty 10s I'd go... and maybe I shouldn't have ventured off that 10s ship in the first place since I already knew I liked it.

Thats a tough one.
Old rock like Boston has no low frequency content to speak of. Certainly not enough to cause audible port noise on a quality sub like the Rhythmik.
I would say what you hear is something else.

But, it's real hard to say anything bad about RSL subs....I have 4 of them.
Maybe a 12S is in your future ?

Do you have a 12s in the same system as your stacked 10s ?

Sure do....I have another 10S I don't use. It's in the same room though.
I use the high pass crossover in the 12S to run the stacked 10S's at a higher point....upper low bass if you will.
In my room, this works extremely well.
Using the third 10S creates problems, as can be expected...so it sits waiting to be used somewhere someday.

nice... I like the white 10s w the black cloth, looks cool. Is that a Q Acoustics center channel?

Thanks, I wish my 12S was white, but white wasn't available when I bought it....I will probably paint it this summer.
That is a Q Concept center.
I have a third RSL CG25 for a center, but for some reason I prefer the Q.

I don't buy that any of these subs could affect dialogue at all unless there is a major set-up problem.
