That would be funny, if it wasn't tinged with a knats grain of truth!

I am all for vintage. I would guess they sound fantastic. And look brutal. I think it depends on what you grew up on. I love that old in ya face kick. Much respect to mr francis. I totaly get his thinking. Just wouldn't want to lug them. I bet it's worth the pain however. Please keep posting to keep the dance stack off the top.

Teenage me stood in front of a huge pile of F2B and that was the first time my jaw dropped from sound, so I have a soft spot for this sort of design. There’s nowt wrong with it!

I don't overstand you think these are heavy , they aren't 115kg with the changes , anyway I don't do venues with stairs , If a venue has stairs they can carry the stuff on their own or pay extra for movers . work like a pro ,

I would think that three of these are about the same size as two lab horns. Push out alot more sound I would think. So well worth the move.
Bob I only take the labs to out door and big Gymnasium type events now. Have done stairs not any more. Trying to move on from them. Just need time to build something else. Got 12x18inch drivers waiting.

I am fairly sure if you stood in front of it today, with all your experience, you would still be impressed - 2x15", 500W (peak!) each driver, essentially flat from 40-200, and 107dB 1W/1m!

If you wanted more,

Martin FSX, 2x18", 101db @1 W @ 1m... in big enough stacks "...full output is maintained down to 28Hz..."

As I keep bleating on about, the laws of physics haven't changed; just our fashion for systems measured in MWatts (despite still only making 135+ish dB) and able to reproduce 20Hz like 100Hz.

For live music, the instruments haven't changed that much, only the keyboard and electronically synthed noise will ever create 20Hz, so what is the point?!?

Our desperation to produce that 20-40Hz octave is really distorting our attention away from efficiency, as much as sound quality in other pass bands.


There is a lovely bit in the Martin F2 User guide, where it compares Box A, Box B and Box C.

Box A - 107dB 1W/1m 1000W, Ten cabs in 3 foot of truckspace

Box B - 102dB 1W/1m 1200W, 12 cabs in 3 foot of truckspace

Box C- 102dB 1W/1m 1600, 9 in 3 feet of truckspace.

To produce same SPL as 10x Box A, you need 26 Box B, or 20 Box C. And amplifiers...Twice as many lorries for same SPL...

Obviously Box A is the F2B!

One of if not my favorite all time bass sections, lovely sounding with phenomenal impact.
