Funktion One F121

how many F121 do you need "enough" for this space?

chest pounding way back to foh position around 30-35 meters

area is 60m wide by 80 long.

I agree with Phil, 60x80 is a big space and 16 x 21" in total with the right amp should give a very good result. 60m is very wide so you need a lot of top boxes to get proper hf/hm coverage.

The f121 has a very useful wide operational frequency range and can can be used 20Hz-125Hz no problem, with  the right power amp they also can produce massive and exceptional sound. We have 12 of our own and the single driver version is easy to transport and load in. The F221 is very large and I would say only suited to companies whom use Trucks or articulated trailers.

As stated above the driver is manufactured by PD and has a new  chassis designed and tooled by Funktion One (as a side note I believe Toby at Funktion One designed the original 50p precision devices chassis which has has been used for many years now). This chassis is also now used for 'standard' PD 21" neo drivers. The driver has evolved since first being used 2yrs ago as there where a few early mechanical failures so the suspension and surround have been strengthened. The voice coil assembley can take a lot of power and at times last summer ours where tested to the max.

maybe terrible phase response is what the people dig....see scoops for example :)

with audio 'right' is impossible in my book, however there are some types of wrong i quite like

a speaker should reproduce the input signal delivered by the amp. what it sounds like subjectively is the most important thing but it has been established that certain measurable things corelate to how good it sounds to the ear - level response, power compression, phase response, impulse response etc. i agree some speaker distortion sounds okay for some music but if you want loads of harmonic distortion  then change the input signal.

btw are there any measurements online of any fk1 bass speakers?

It's all about the F221!!!!! Heard these at boom festival, 2 stacks with 4 a side, with 10 res 5's a side and 2 delay stacks with 3 a side, with 3 res 5's a side. Never heard bass like it not bone shaking but f**king earth shaking bass absolutely unbeleivable.
