Ok, thanks Ivan & all other that chime in.Think i am stuck with my stuffs unless they go poof...Really appreciated.
Dennis,i wen to test the single srx 718 but it failed, however the sound appear when srx 728 comes into play..i also try couple two piece srx 718 together to VS one piece 728 at the at the distrobutor...sounded different.So, why is the dual 18 cab go lower then using two 18 cab?coupling is +3db(extra driver) & +3(voltage to them)...assume they are hung in mid-air.
Dennis, Where are you located?
The SRX 718 is tuned higher than the SRX 728, about 40 Hz Fb (box tuning) vs 35 Hz.The extra box volume of the 728 (more than double the size of two 718) allows a lower Fb with similar output level.Ported boxes just don't do much below Fb (box tuning) other than flap.Few PA boxes are tuned much lower than 35 Hz, as the size vs output ratio goes down steeply.Room size, shape, and sub position and listening position also can make a huge difference in low bass sound.My home stereo uses a sealed dual 12", it rolls off at 12 dB per octave below 40 Hz, in room at the listening position is flat to below 20 Hz, but only around 100 dB. If you really want sub 35 Hz at very loud levels (125 dB or more at a one meter equivalent), you will have to do it yourself, or pay big bucks for the few manufacturers that actually do make things that go that low, DSL being on the short list.Art
Dennis....There are quite a few threads discussing sub-woofers. Some are about the gear, some are about the application (what gear for what purpose). If you can take the time to do some Forum searches and read as much as possible of what has been posted on this subject over the past several years, you'll probably get a lot of your questions answered...and probably have a few more!!!Welcome to the PSW and good luck.
, maybe i expect too much due to the price i pay as i am a miser. Or always trying to achieve something with lower price spent, which i guess in reality, cannot be really done. Just like when playing cars.
For VALUE you have to look at all the issues-freq response-sensitivity-wattage-distortion-physical size-amp requirements and so forth.When you do that-you will find that the "cheap products" are not so cheap anymore-as compared to real products.You may get louder with more cheap gear-but it will never sound as good as the real gear.
Too bad you feel you have to stick w/ single 18 cabs. What Mr Art Welter said about the SRX 718's and 728's is true also for the Wharfedales delta 118b and 218b. The double 18 box is tuned lower. As the 218b is down only 3 db at 30hz you might have your dealer demo a pair for you and see if it gets you there?
