I do recommend stands from Skylan stands out of Calgary. These are extremely well built and and sand fillable.
At this time I have 2 subs available. Both are low Q sealed self powered subs.
8" 150 watt, part of the Minimax system. This sub sells for $399
10" 250 watt, $899.
Both have variable crossover, volume and phase, and can be ordered with any of the standard finishes.
