I'm in process of trying to construct a subwoofer using two Fane Colossus 18XBs which will be good enough to provide quality low bass for my excellent hifi setup, but also have the muscle to provide decent performance with my home theatre kit. I've got access to good facilities and materials for making the cabinet, but I have had conflicting advice about the best way to proceed, so I was wondering if there was anyone out there who could answer these questions for me:
1. :frowning: Should I go for a vented box? If so, should it be about 200 litres?
2. :frowning: The three different software programs I have conflict about what size to make the ports, and indeed therefore what to make the resonance of the enclosure - I want the beast to go down reasonably to about 20hz if possible because I listen a lot to organ music.
3. :frowning: Instinct tells me that I should make the drivers downward firing, but am I barking up the wrong tree to think this?
4. :frowning: I'm going to need a really powerful sub plate amp to drive two Collossus 18XBs in parallel - about 600watts RMS+ into 4 ohms. Does anyone know of such an amp, which can operate at 240v? (I'm in the UK)
5. :frowning: I already have the two new Fanes, so I really can't afford to replace them, but are they up to the job, or was I badly advised even about them? I don't doubt their ability to produce the SPL required, but can they go down low enough for what I want?
I've got lots of other questions, but I would appreciate someone giving their learned opinion about the above. Cheers - JB
