Subwoofer boom is too much for me...

Subs are good for one thing and one thing Only....Home theatre...........They are a Detrimate to two channel sound.....You say "but I have bookshelf speakers and need a sub...I say " Get a good pair of towers and you won't need the Boom"

Before we moved the listening room I had in our former home was roughly 24' x 26' and the room added a single bass note that had no relationship to the bass line of the music I was listening to.  I tried moving those 133# beasts around the room and the only place that the boom was mitigated was behind the sofa about midway between the 24' walls.  Though the boom was reduced, the "visceral" effect of the bass was that it was coming from behind and the rest of the music was coming from ahead of the listening spot.  I eventually had to purchase ten bass traps, which improved the sound about 85%.

The dimensions of my current listening room are great for integrating the subs with the main speakers, so my advice would be to sell you house and move 500 miles to a new home with a custom built listening room...  ;-)

I agree you don't "need" a sub as long as you have full range speakers. There are some advantages to monitor/sub setups vs towers. Generally the best location for bass output is different than the location of your front speakers. if you use towers you are locked in, if you use subs you can place them anywhere.

This is wrong.

A Sub is an enhancement to a two channel setup. It makes up for difficiencies in bass, dynamics, and clarity.  I think they are especially useful for a lower power, reciever-centralized system: where the owner has no desire to put up extra money for higher-end seperates.

A good quality and well set up sub should always enhance a two channel system's sound. My small towers are nearly flat to the low 30s and an REL Britannia B1 sub 'opened' up the room and subtlety made the lowest bass a solid musical foundation.

I've since move to four good quality subs in a distributed bass array in the 16 x 21 x 10 room and you'll never know where they are; they are so low. With a bit of room bass correction it works quite well. I still need to high-pass mains for better sound and dynamics by relieving them of the low bass load. My bad so far...

As for the 'boom', I'd sure try a sock, and positioning, and crossover frequency and level. I always had better success passing very low (30-40s) and using a tad more volume. It depends on the mains.
