...and let me preface this by stating that I have absolutely NO doubt that the subs from companies like SVS & Hsu etc. are worth every penny! My question is this: where do the prices from subs come from? obviously a reasonable amount of $ goes into the engineering of a sub, but what about actual physical material costs? the cost of the drivers/amps used etc.? the cost of the beautiful finishes? the reason I ask is that I may never come to the point where I could spend 600$+ on something like a sub, but would love to have the great sound (or something close) to what the "better/best" subs sound like, & would love to build it myself...I have little to no concern w/ how the sub LOOKS, but a lot of concern w/ how it sounds! am i foolish to think that I could even come close to the sound of an expensive sub w/under 300$ worth of material, a lot of research, and some hard work/creativity? are the drivers/crossovers/amps etc. found in these wonderful higher-end subs really so much better than say a PE premade Xover/ 250 watt all-in-one amp, reasonably priced sub driver? I'm sure the companies everyone loves use awesome materials/drivers etc., no doubt...but one day when I decide to build my own sub, am I going to be disappointed (assuming of course I built it correctly )? any & all opinions are welcome!
