Rockport Avior II's in 19x24.5 room?

The bass from the Aviors was excellent in my experience and they would pressurize my room depending on music type, volume etc.  It depends on what you mean by pressurizing the room as to whether you would need subs or not.  As an example, when I played electronic/House music they had no problem pressurizing the room.  If I played AC/DC, I would feel the thump in my chest but it wouldn't pressurize the room the same way, but it's not supposed to IMO.

If you're a bass head then I'd recommend subs as the Aviors play clean, accurate with articulation and detail - not boom.

Another option is to add some DSP somewhere to bump the bottom end.  I did this with my Weiss Helios DAC.  It's great to be able to fine tune your sound when the mood strikes!

While I do love classic rock, I would not say I am a bass head. I do love viceral low bass which when in the program material I feel in my gut (not kick drum bass but lower frequencies) due to pressurizing of the room, which for most would mean the addition of large subs, and it will likely be required for my objectives as well.

I am strictly an analog music listener for all serious sessions, but do have a digital system and do stream to find new music to purchase on vinyl.  

It is difficult to hear many brands of speakers without serious travel here in Texas.  I am trying to narrow some choices down to then make strategic trips to listen to speakers that are within budget and the type of sound I want.  I am not a lover of analytical speakers, preferring a more smooth and impactful sound.  The Rockport Lynx's I heard were exceptional and so were the Avior II's but they were set up in much smaller rooms than mine.

Room's treatment is half the sound . The equivalent of a preamplifier some say.

Maybe with appropriate room treatment , the Avior II  would be up to the task .

That is being addressed.  I have an acoustian working on my room treatment design.

I am very pleased with my Audiovector speakers

 But my room is smaller than yours.

But a lot more expensive than the R6 Arreté

I live in an appartment .....so nothing too crazy on the DB  side .
