Need help with sub selection


Downsizing to monitors (monitor audio silver 3's) for a while,
with a buget of $500 (used) any recommendations on a small sub
no larger than 10" driver.

Thanks in advance

Bob, you are using the amp in the sub. Because of the very different impedance the main amp will not send any power to the sub, only a signal.

Bob, I think that disturbing the signal to the mains with a high pass filter or external crossovers usually introduces undesireable grain in the mains-- short of rather high $ implementations. There is no problem with bass augmentation mode with LFP in the sub as used by REL or Vel DD-- provided the system is set up carefully.

The Rel Storm 3 that I own has been set up quite meticulously, and the crossover is set at 27 hertz. It integrates quite seamlessly with the mains, which run at full range. It augments the lowest of the low frequencies but apparently does not take any bass load off the mains. The result in my system is excellent, for now.
