Dual subs and or speaker uograde


I have Monitor Audio Gold 300s as my front mains. All Gold speakers 100s for surrounds, 300Gx center, Gold GX rear surrounds.
Paradigm Sub 12 Reference as my sub.

Room is 10'w at front, and 18' wide at rear. 7.5'H, 22' long and 13' from front wall I have my 3 theatre seats,

I feel I need a little more umph for watching concerts on DVD.

I have about 15k to spend.

I am considering dual Persona subs or dual B&W DB1D subs to augment bass.

Other option is Persona 3F with 1 Persona sub ( a little over my budget) or Persona 3F with 1 B&W DB1D sub (on budget) or Persona 3F and 2 SVS Ultra16 subs.

Another options is GoldenEar Triton Reference, but due to 10' front wall with 100' screen, I'd need to put speakers fairly close to front outside walls 10-12"


Appreciate your opinions.

My audio store sells all except GoldenEar. They have given me great service.

My amp and preamp are NAD M27 and M17. I'm happy with the quality of the sound of my Monitor Audio 300s. Great sound. Not enough umph.

Thanks Roger

Just FYI:

There's no truth to the idea that smaller subs are faster.  They just won't exacerbate the lowest octave as much.

I strongly encourage you to play around with REW's room simulator. It will help you understand placement, and options without lifting and shifting.

@musicaddict - I've never heard a system, crossed at 40 Hz which didn't sound better crossed at 80 Hz when properly done.
PS _ You can also use REW to help you place your single sub more ideally. That is also a good thing to do before buying anything.
I would absolutely not attempt speaker changes for this. Those are fabulous speakers, but maybe a second sub.

The very first place to start is room acoustics:

ATS Acoustics
GIK Acoustics

Wall panels will reduce mid/treble hash and output, and improve clarity.  Bass traps will make room correction work better.

Regardless, seal the main ports and re-run the room calibration. You are allowed to raise the bass level by the way, if you don't like the end result.  This will reduce amplifier strain, Doppler distortion and driver excursion.

After you have done the room calibration, a second sub could be really good if you have flexibility in placement.  If you want to simulate this, try Room EQ Wizard's room simulator.
