Looking for Opinions on Setup using 4 Sealed Mach 5 FTW 21" Sub Woofers

Hello Everyone.

Just a quick introduction. My name is Allen and I live in Ontario, Canada.

My system consists of this

-Anthem MRX1140 receiver
-Paradigm 8000F front speakers
-paradigm premier c600 center channel
-2, paradigm X12 Sub woofers
-paradigm monitor 7 V5 side speakers
-paradigm monitor 11 rear speakers
-4, paradigm PR80 in ceiling atmos speakers

The room is 27 feet long and averages 15-20 feet in width with a 7.5 foot ceiling and comes in at just short of 3600 cubic feet, with the listening position in the center of the room.

I mainly use this as a home theater setup(70%) but also listen to music(30%), so I do like a wide variety of bass.

Low frequencies down to 10-15 HZ are important to me, but so is the mid bass punch from 30 HZ to 80 HZ

Obviously I am not getting much mid bass punch with 2 X12's in a huge space and I have to over drive the X12's in movies and the bass becomes muddy at low frequencies.

So with some research and some products being highly reccomended, I decided to purchase 4 of the Mach 5 Audio, FTW-21" subs as I have heard very good things about them

They will be going into 4 seperate sealed boxes, 6.5 cubic feet and two placed across the front of the room and the other two directly behind the listening position.

The purpose of using 4 is becasuse I want to hit low frequencies for movie watching while still having good output and want to have massive mid bass punch.

Basically I want to cover 10-15HZ all the way up to 80 HZ(sub cross over) with massive clean output and not have to deal with the "muddy" bass of ported boxes.

I will be using a CVR D-1004 rack mounted amplifier that outputs 1700 RMS watts at 4 ohms x 4 channels

I will be using a Mini DSP FLex HTx to seperate all the sub signals, and also because I need to convert an unbalanced signal to a balanced(XLR) signal with no signal loss.



I came over here from the AVS forums and just wanted to get opinions/tips on this setup and possibly any reccomendations for changes moving forward

Keep in mind the 4, FTW-21" subs are already ordered, paid for, so I am at least committed to these.

Cheers

Allen
