Dear audiophiles,
recently I was trying to build myself a Subwoofer. As ist turned out the amp (Monacor SAM500D) I got for the build died prematurely (see my other thread
), so I will have to start over. So far I have a 12" ScanSpeak woofer and an enforced closed wooden box with a volume of about 120 liters. So I will need some amp to power it now. I might have to add, that this is my very first DIY speaker, so maybe I didn't plan the amp part well enough in the first place. I just got the Monacor since I got a "good deal" on it. During the process of building it I got thinking that maybe it would be even more reasonable to not add a classic subwoofer amp like the Monacor to my cabinet but rather use an external one.
A few words on my current setup: I am using a Wiim Pro as a streamer feeding optical to a Quadral A10s amp. The amp powers a pair of Quadral Galan (or Heco Direkt) and I use the Wiim's equalizer settings for basic DSP. The Quadral A10s has no subwoofer out, but it does have a "pre-out" which I was intending to plug the Subwoofer to. Obviously I will need a crossover of some sort to feed the low frequencies to my sub. So the question is how to proceed now. I can think of several options (maybe you guys can even add a better one or help me choose):
- Get a classic Subwoofer amp which brings a crossover and maybe even DSP and add it to the box. Just one that works (better than the Monacor
). Which one? Maybe even the low frequency DSP part can be done well enough by the wiim
- Get an external amp. Which one? I recently found the Yamaha px5 which looks interesting since it has enough power and DSP and should do the Job. I could not find any reasonable reviews on this particular one. It would offer the possibility to add a second subwoofer later on if necessary.
- Get a basic internal/external amp with no particular features (which one?) and add a "reasonable" DSP to the system like a MiniDSP Flex to provide signal to both amps stereo + sub(s). I was considering to add some better DSP to my system anyway. Maybe it is more reasonable to have such a "central DSP system" as opposed to add several components that somehow do DSP
- Something completely different?
