The order of getting more/better bass

The TAS article is OK but there are a couple of points I disagree with. The first is room size vs woofer size. An 8 inch sub is not going to go very low. It just can not project. Multiple 8 inch drivers may be able to get down to say 30 Hz but still they will not make it down to 18 Hz where the action is. It is those low frequencies that give you a sense of venue size. In a small room you need at least a single 12" driver or multiple 10 inch drivers. As far as room size is concerned, you can make bass in a telephone booth. It is just hard getting in there with the sub woofer. Yes, larger rooms are easier to deal with but you have to work with what you have and I have heard some seriously good systems in 10 X 15 foot rooms. It is harder to get the bass right but it can be done just not in the short time you have to work with in a "show" situation. Next, a system Q of 0.5 is too dampened. You will never get the impact of really low bass. I like 0.65. You get detailed bass and super low frequency impact. You get more impact if you go higher but you start losing detail. The home theater subs do this. You can accomplish the same impact and maintain detail by getting a second sub. I use 4 12 inch subs with a system Q of 0.62 (hard to get it perfect). The bass is very detailed and I can make your vision blur with bass drum strikes, the best of both worlds. You also have to be careful to use high powered amplifiers with very high damping factors 500 or higher with subwoofers like this along with very short low gauge wires 8 gauge or lower. Good subwoofer drivers have huge inductive motors and throw a lot back at the amp. People who are silly enough to read my posts like cleeds and geoffkait know that I am not crazy about bass traps. I have never seen them work. Just place the sub is corners and if you can place a third or even fourth sub along the wall wonderful. You have just made yourself an infinite bass line source which will which seriously limits reflected energy to the ceiling and rear wall. The rest can be easily cleaned up with room control. You might need 6 dB of correction here and there. Nothing crazy. Mr Hartley is certainly correct in saying the best bass is expensive. Erik, you make speakers! Sub woofers are easy. There are a gazillion great drivers out there now. I think Dayton makes the best for the money. My personal favorite right now is the Morel TiCw 1258 but it is 3 times as expensive. 1" MDF is not enough. The thickest you can get it is 1.5". I like at least 2" so I laminate two 1" panels together with epoxy (System One). Glues like Titebond use water as the solvent and can make the MDF swell. You can make a real stiff and heavy enclosure because you don't have to worry about shipping and labor costs! |
