Here is a rule of thumb - if you can hear male vocals out of your sub you have bad bass period end of discussion - and I have heard awefully expensive ones do that. hen people will talk about where they're crossed over - but IMO this should not even be an option.

The problem with most full range speakers is that when you find a good spot for the midrange and treble you might get boomy bass. I think the main reason Audio Note is able to succeed at getting tremendous bass from relatively small cabinets and one 8inch driver is that they take into account the rear and side walls as well as the floor bounce and will get very similar results from room to room - presuming your room has 2 corners in it. Most do. But again Sir Terrance notes that it's not cheap.

Now i have heard some very deep(or 35hz very powerful and very loud) subs from Paradigm which whenever I build my home theater(very low priority for me) I would be extremely happy with and only cost about $800.00Cdn. Musically It wouldn't cut it for me.

I had that option of going with a $1k sub and my Standmounts which were good to 36hz. Or Spend that $1k and get a bigger standmount which is good 25hz. There was no doubt that the latter option was and is the better option musically. Having bass come from a seeming front source point source is indiscribably better in my view. Even big floorstanders with similar bass depth sound as though the bass is thudding from the floorboards. Imaine 25hz coming from ~2.5feet off the ground - projecting up where the stage is. Non Directional subs my ass.
