lol I haven't heard a lot about their new subs since they came out, or maybe i'm missing out on something. |

i was genuinely surprised yesterday to find that what i had assumed for a while of seeing them out and about were f118's were actually f121's, not in terms of output, lots and lots of noise, but they were damn punchy in the upper bass for a 21" driver, not sure weather i can specifically recommend them over the competition but depending on the crossover they do sound good.

I installed a club in a basement, quite low ceiling. After moving the subs about to find the right place for them in the room, we chose a spot. 4x F121s in one pile from the floor to the ceiling, brutal. Love 'em. |

freaking awesome loudspeaker... i remember their debut at glade's origin stage a few years back, all the speakerplanners who'd got together were speculating over the possible loading when we'd seen them stacked, a gesticulative conversation across the dancefloor with john newsham (conducted by various eyebrow inflections, pointing at speaker stacks and holding up multiples of fingers) confirmed they were 21s... multi voice coil drivers leave the car audio world and enter pa with a bang! or rather, a bang, whump and thud, for yes indeed these cabs kick beautifully high and drop pleasingly low. i've only heard them playing dance music, but they do that with gay abandon. james. ------------- mardy hippy. |

It is but I believe its basic origin is the PD neo 21" which then got pimped by the farm. They are stupidly nice bass bins though, just a pity about the size/cost for us mere 218 using mortals  |
Posted By: Sound4hirecouk

The PD21 is Tony Andrews-Turbo design which was re-used for the F221. The chasis on the early F121 & F221 is the old flood and flashlight 21 with a Neo magnet. The Chasis has since been re tooled with a Funktion-One tool at great cost to Funktion-One. A picture of the tool is available to see on the website, under Misc pictures. So, its a F1 driver, Neo magnet and dual voice coil. The F121/F221 is the most Musically sounding Bass bin availabe on the market-in my opinion. Brown stands for L-Acoustic. Hope this helps, |

I had purchased four last week and used them for the first time last Friday in Piques in Cannock and Saturday at the Revolution Bar n Club in Walsall.
Absolutley stunning, had the police at the venue to turn down the bass on the Friday gig and on the Saturday we pissed the Dj's off in the club next door to the bar I did... also the club over the road WS1 was curious what the hell was going on and the whole of Bridge Street, walsall wondered what the hell had hit them..!!!

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. Cheers D |

i doubt very much that a bandpass horn is the most musically sounding bin available. terrible phase response is unavoidable in a bph design. and 40Hz cutoff isn't great either. they are efficient and play high but for their size they don't go that low or sound that great. Phil |

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 ------------- music is god |

yeah, read through and agree the 21's are lovely sounding. F1 has a good nact at taking large cones and making them sound very musical (res 1.5 for example).
i will agree with rich on his above comment. There is no right in this industry, its all down to personal preference.
also, theres no such thing as a 'perfect' speaker. Everything has its uses. I dont like hearing horns in small <150 type venues, i have always had smoother warmer and generally better results with reflex/bandpass type cabs. Then theres cases of discreet installation, or people wanted pretty 'arcitectual' speakers (like voids airsys), people needing really compact rigs, etc etc.... ------------- ''Remember that the object of a subwoofer is to enhance the output of your main speakers, not overpower it'' ''Dubstep - an elongated electronic fart'' |

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. |

my point is that NO speaker can faithfully reproduce the input signal to the amp, or rather/ideally the source signal. in that sense every driver/cab/system available is a compromise. you could go out and buy 10 top end systems and each will have its own signature sound. i personally have found fk1 to be one of the systems that comes close to my perception of what sounds good, regardless of how it measures. bp horns have phase issues, bass reflex has group delay, horns get honky, scoops....meh, you get the idea, arguably for the past 20 years with the drive to make cabs smaller, availability of hugely more powerfull amps and spacky processing sound has generally taken a back seat over things like convenience. fk1 is one of the companies that has taken a more oldschool aproach and benefits from it in my opinion. ------------- music is god |

The FK1 gear does go low in large numbers (F-218s will hit 40hz pretty well). FK1 boxes aren't perfect but they are clear and smooth to listen to at high SPL.
I don't think phase response is of that much importance when you hit the low notes, your ears cannot hear absolute phase.....
Group delay is a different matter but nearly all bins suffer from some sort of group delay issues.

The X are an all round bass bin - the psychos are pure long horn sub. Different bins, different applications. Overall output per number of cabs, the X is phenominal - but for pure, effortless sub, Psycho every time. As long as you have a venue big enough to hold them. |

I normaly dislike the bandpass horn sound but I must say that I have been massively impressed by the 221 bin. It sounds much more polished than any other BPH I've heard; I had made exactly the same judgement as you before I heard them.

Hi everyone, I'm replying to this topic and taking the opportunity to ask a question. I have to set up the stage of an event with an F1 sound system consisting of: 3x RES50 on each side, so 6 in total 4x F121 and 2x F221 A band is to perform on stage and only after the band has finished will a DJ set begin. My idea was to use a single central bass stack set up as follows: 1x f121 front 1x f121 rear in cardioid mode 1x f221 front 1x f221 front 1x f121 rear in cardioid mode 1x f121 front For greater accuracy, I've attached a PDF image of the front view of the stack Given that I can't increase the number of subs and I have 2x 221s and 4xf121s available, I had thought of this configuration. In addition, by controlling the f221s with 2 channels each and having the right amount of channels necessary to make an electronic arc on the subs facing the front to maximise the coverage of the array, which would otherwise become very narrow. I accept your advice. Unfortunately the stage is 80 cm high, which means I can't tighten the stack by placing the subs above a first line. With a little effort I could replace the F221s with another 4 F121s. I await your news and thank in advance all those who will reply immage of the config: https://files.fm/f/gt9axdtdrw |
