Just how far are they really behind though?
Looking at the Data-Bass tests of both drivers in a 4.2 cu.ft. box, the Dayton is down 8 dB at 10Hz, 6 dB at 20Hz, and from 20-40Hz it only trails by about 2 dB average. Simply adding another Dayton for $250 gets you equivalent output at 20 Hz and +4 dB in the ever-important 20-40Hz range. Add 2 more Daytons -- for a grand total of $6.05 more for 4 than the single LMS
-- and we now have a 10 dB gain in that range! Plus, you have the added benefit of the option of distributing cabinets throughout the room for evening out room modes. But wait, there's more -- you also don't have to roll the dice and play the super-fun game of "Clone Lottery" to see if you will get one of the relatively inexpensive high power amps that it takes to drive this monster that doesn't blow itself up.
Yes, the LMS is amazingly clean in the distortion and sound quality arenas and goes in tiny cabs, but WOW is it ever expensive!!!
I would have to put my money on the 4 Daytons loafing along while still easily outpacing a single LMS 5400.$7406.96
for notnyt's 8 drivers from Parts Express as of today!
Holy crap, I don't even have that much into all of the sound and video equipment in my whole HT room! And it's no slouch either...3 Yorkville U15 Unitys for LCR, 4 SEOS horn kits for surround, 8 Stereo Integrity 18" drivers in quad IB manifolds, 4 QSC amps (2 DCA1622 2-channel, 1 DCA1644 4-channel, 1 CX168 8-channel), QSC DSP's (a Basis 922dz and 2 DSP-4's), and an Onkyo PR
-SC885 processor. This leaves me just shy of $2400 leftover to buy the yet-undecided projector, Blu-Ray player, and a Jamestown/Seymour AT screen -- which will be done because I have 100% light control and don't want 3D. Yes, all of the audio equipment but the IB subs was purchased used, but it is all in very good condition.
I'm in no way trying to undermine or take anything way from notnyt's system. I believe it to be one of the finest bass systems on the forum (70 liters of Vd!) and am sure it sounds totally incredible. I am also sure he is quite comfortable knowing how much he spent. The point is...damn, that LMS 5400 is expensive!!!
...and I believe less expensive drivers in multiples are a far better way to go for 98% of us (as I bet autox320 does as well; just wanted to illustrate it).
