If the HSU cylinder subs interested you check out the SVS site. They have active and passive cylinder subs in 3 sizes I believe. I have no experience with them but it's the first thing I thought of when you mentioned hsu.
looking for quality passive sub with 8" drivers
Anybody know if there are any passive subs with a pair of 8" drivers? Am thinking of this configuration as these drivers will be very quick and sound better than a larger driver. I would drive the amp with a custom built amp that only operates at low frequencies so there is no need for a crossover.
Hsu no longer offers their 8" cylindrical models; pity.
