Hi all, As a follow-up to my last thread, I’m down to the following choice. Should I make the following: My only hesitation with this beast is that it will stand about 83” tall. The following is a cost estimation: 2 Tempest drivers$300 HS500 Amp$500 BFD$130 Sonotube$ 75 MDF$ 30 Baltic Birch$ 20 Misc.$ 20 Total: $ 1,075.00 I could probably find a cheaper alternative for the amp. Or should I make this: The following is the cost estimation for this sub: One Blueprint 1803 driver$280 QSC RMX 1450 amp$400 BFD$130 Sonotube$ 55 MDF$ 30 Baltic Birch$ 20 Misc.$ 20 Total: $ 935.00 I’m going to need a BFD either way due to room considerations. So I guess from a cost analysis, the price for each sub is similar enough. Of course, from what I’ve heard, I might have to live with fan noise with a QSC amp. This sub will be used for about 70% hometheater / 30% music. I am mostly concerned with hometheater sonic punch. So what do you guys think? Which one would you build and why? What amp would you use? Thanks again to everyone!
