I am not aware of any religious fight. Over her in Norway I don´t see anything like this. It´s about the execution of the design.... A really well designed subwoofer will do the job, whether it´s sealed or ported, transmission line or passive radiator... (arghhhhhhh: I don´t have space for TL subs)
The one major tendency to disagreements I can see where I live is the controversy between DIY´ers and not-DIY´ers where some in the first camp insist that DIY is the only way to go while the latter claim they will not get close to the performance of a commercial design. I think, however this is more of a friendly fight than an ugly one. However there are some DIY´ers in here at AH that made simply stunning speaker and sub systems that you will just not find as commercial products... ref those stunning TL subwoofers
But this has nothing to do with the Monolith, so sorry guys if I am getting off track... The point from me jumping into the thread is that these subwoofers seem to be priced at a level where DIY maybe doesn´t really make that much sense, there seem to be not to much to save. The quality of the drivers and the execution seem to be astounding at this price level, but I can´t say for sure as I have only seen the photos and not in real life. But I would really like to see and hear them.... No overseas distribution though!
