In Reply to: Is there any audible difference between speakers going down to 30H and others at 50H? posted by D.D.C. on September 28, 2001 at 23:39:51:
that everything else is equal and only the lower cut-off frequency varies between 50Hz and 29Hz.The first problem would be with comparing the 2 specifications. The exact same speaker could have a spec. of 50Hz @ 0dB and 29Hz @ -6dB for example. So firstly be sure that dB is mentioned along with the frequency.
Like everything else in this hobby, the extra frequency extension can bring huge benefits, but also disadvantages.
First the benefits:
A speaker with deeper bass will have more slam, weight, body and obviously extension. But in addition, assuming the bass is really clean, the extended bass will also add air and space to any large, reverberant recording venue. 29Hz will be beneficial to most music but especially rock, organ and symphony orchestra. But not all about low bass is sunshine and light:
Golden rule number 2 in hi-fi.....too much bass is worse than too little. The extra extension to 29Hz can excite a whole lot more room nodes and could cause some difficulty in dealing with room resonances. The lower the bass, the more critical the speaker positioning and the more difficult it is to balance room acoustics.
Low bass, if not executed extremely well can make a speaker sound subjectively slower and lacking in pace
The larger and heavier a speaker's woofer, the more demands are placed on the amplifier's ability to control the driver, so the combination of speaker and amp play a decisive role in choosing between alternate speaker models with different bass characteristics.
In theory, 29 Hz is going to cost more to produce than 50Hz (all other things being equal, which they never are). Drivers need to have greater area and larger motors to move the additional air, while enclosure size needs to be increased to accomodate the larger driver.
So as you see, there's no easy answer....but if I had to choose between a well set up speaker with 50Hz @ -3dB and a more extended model with uneven room response down low, I'd go for the former, EVERY TIME.
