Martin-Logan Descent or Rel Stadium Subwoofer

I have a pair of Quest Z's & a Stadium II between them. I have tried numerous subs & sold them all because I didn't like the sound. When I bought the REL;theML sub was not available. The REL is seamless in it's presentation vis a vis the Logans. Larry W

I have to respectfully disagree with Gtejr; the stadium III is a major step up from the storm III (which I have owned also) in both extension and authority, giving an overall impression of much greater you-are-thereness. A lot will depend on the size of the listening room; if you are only loading a small room and don't need to reach into the 20-Hz range then the strata/storm will work fine. If you have a larger room and/or value what 15-Hz extension does for the soundstage, impact, and presence of the system (not to be underestimated, IMO), the stadium is a minimum starting point, and the stentor is definitely worth a listen as well.

Skip the Stratus III. It is a great sub for what it costs, but is a closed box design and does not go nearly as deep as the Storm III or the Stadium III (which is deeper still).

I am not sure what Karls is saying. All REL subs have High-Pass adjustments. Their high-pass side is what makes them great for audiophiles. If he is running off the amp speaker terminals, then he is running high-pass and I assume he adjusted it to blend/integrate it with his system. (Maybe not?)

Sugarbrie, in filter design the term "high-pass" refers to a filter which "passes" the "high" frequencies, i.e., blocks out the low frequencies. Similarly, "low-pass" is a filter which blocks out high frequencies. Thus the RELs have no "high-pass" filters whatsoever; they allow the amp signal to run full-range to the mains without any interruption or filtering at all. They do, of course, have the best low-pass filters on the planet.

I have the Descent and it seems to match very well with my ML Reqeusts, Areius I's and Cinema. Once I put it in the room it just disappeared.

It puts out a ton of bass, I think I have the volume set to around 2.5 and it is not corner loaded.
