Your sub experience: Easy or hard?

I don’t have much experience with subwoofers so my contribution may be worthless. Easy or hard? I suppose the question is closely correlated to expectations? To me, proper integration means the sub blends rather seamlessly with the main speakers and nothing sticks out like a sore thumb. I don’t know, but for a seamless integration the impact of the sub is usually small so as nothing sticks out like a sore thumb. A small but appreciable difference. In my case, I would say easy but as mentioned above, the impact of the sub in my system is not very significant or earth shattering.

I’m still trying to figure out if a superior sub will bring a more significant difference to the system, and whether the integration of the sub will be equally easy or require more effort. I will soon find that out..

I use two Velodyne HGS-15s in the front corners with an SMS-1 acoustic bass manager that makes integrating them pretty easy.  The surprise for me was a third HGS-15 in a back corner that takes LFE from a Bryston SP3.  It's not used for music, but often adds an interesting effect for HT.

Easy (REL S/510).  Suggested corner position? Nope.  Put sub in listening position, crawl around, find optimal, set level and crossover.  Enjoy.

I have a single REL T5i accompanying a pair of Janszen P8's.

Integration was pretty easy.

The T5i (8" down-firing) is about the smallest sub I could use and still make a difference. With room-coupling, it's enough to level out the frequency response from about 10hz to 35hz.  I used REW (frequency response analyzer) to help find a good location.  

I tried a much larger , more expensive REL sub but returned it.  I found it a little overwhelming.  It did not seem to make the system sound better overall and was too heavy to move around easily by myself.  Still, I'd like to try one of the smaller Rhythmik subs, just to see if something larger could pressurize the room better without adding distortion.

I am surprised that the MJ Acoustics subs aren't more popular. Once you decide on placement, everything else (gain, x-over, phase etc) are all adjustable by a small remote. Made it very easy to integrate into my system all by myself.
