Yes it would indeed take several of the 18" inch drivers (sealed) to match an F-20 in terms of output, but, the sealed 18 inch drivers will likely go lower than the F-20, assuming that they have plenty of power, right? Of course, in terms of output, it would be hard to beat the F-20. With that being said, there are a lot of folks out there, who, like me, prefer to have a deeper responce that gobs of output. I will say that I have not heard an F-20 in my room, so I may very well love an F-20, perhaps even more so that the sealed 18's that I am building. Heck, I may even build an F-20 anyway since I already have the MFW-15 driver and a spare Yung 300 watt plate amp. I personally think the F-20 design by lil-mike is an awesome design, plus it is super easy to build, especially with the way he has laid everything out. I am looking forward to being in bass heaven soon!
