I'm buying a used sub locally here in Ottawa and I've narrowed it down to the following 4 subs due to size constraints in where I plan to put it. a) PSB Alpha (8" front ported) , b) Nuance S-100 ( 10" dual ported down firing), c) Athena (8" down firing) sub, and d) Energy XL-S8 (8" ported in the back).
I;ve narrowed my choices down to the following two, Nuance and Energy.
Nuance which was a Canadian company that doesn't exist as a company anymore. There was a lot of controversey as people thought it was a white van company. It wasn't. It had a half ass backwards sales structure, a next to useless web site and its products were overpriced. This sub I can get get for $150 ball park. Its very difficult to find information about this unit as well.
The Energy I can pick up for $85. Its claimed advertised frequency response is down to 29 to 100 Hz but I think I will run into problems integrating this sub with the Alpha mites as their -3db point is a relatively high 72Hz. Energy subs like their Mirage counterparts were underated in their capabilities and IHO built better subs than PSB.
