Strangely enough, I think this type of "My CURRENT Sub is BEST" thinking is quite common and why shouldn't it be. We generally only change subs if we think were moving up.
I have heard most of the "big boys" in subs. The VMPS (of course) the SVS, the REL, the Bag End, the Velodyne, the Earthquake, the M&K, the Paradigm, the Krell, the and many others.
Most are very good and most can certainly play with depth and authority.
That said, the argument then goes to "stunning impact" to "musicality".
While Impact is nice, musicality is generally "my" prefered quality.
Can both be had in the same sub? I think so.
There are many "very" expensive subs out there. I think even the SVS flag ship, the B-4 lists for $2550 (with grill) plus shipping in a "passive" version!
Compare this to the fully loaded LARGER:
LARGER $699
MegaWoofs- $140
Souncoat - $75
==========
$914
SVS website states:
There really are no subs that compete. Not 15" subs, not 18" subs, not anything designed for the home market. In fact, we know $25,000 subwoofers that should be afraid right now.
I have no doubt that this is a very impressive sub, as well as a well built one.
But for $2550 (includes $50 grill) plus shipping (say $100) you are sitting on $2650 shipped.
If you go through a VMPS dealer you can get "THREE" LARGERS Subs for that price and have a few hundred left over.
Would three loaded LARGERS equal the performance of a single SVS B-4? Who knows? I have a feeling that both would make even the most extreme "Bass Head" extremely happy.
I do know that I would have a lot of fun using three subs with two being set up like Doug S.'s system in "stereo" and the other run off the LFE or Mono signal for the deepest bass.
As it stands, I have a single LARGER in a 20' x 30' room and it gives me all the "excitment" I need, while being very good musically, at the same time.
Brian has always been known for his "low end"
I mean Bass Performance.
His speakers have also always scored high for musical bass accuracy and impact (just read Anthony Cordesman's reviews)
So it doesn't mean that other subs or designs won't do the same, but I have found that VMPS subs do have those qualities, and that "fills my bill".
