What is Tight Bass?

@chayro 

Agreed mostly. I too am a musician (drummer). I never heard a lot of things put forth in the music world which is prevalent among audiophiles. I always took "tight bass" as a bass line that is quick & sharp. I never heard a bass guitar sound that way except on some funk. I was never able to get good bass from the audiophile SS amps. It was a tube amp which showed me proper sounding bass. Yet, I had always heard that SS was better. It is not.

the bass is stronger. maybe more sharp sounding. not sloppy. the opposite of that. clear and with nice resolution.

Here is the short answer, worth every minute of the hour and a half.

Keep in mind that many people prefer the general rumble, as in car radios and juke boxes.  Gives the sound a comfortable cushion and warmth that is pleasing to the ear. 

If you get the bass too tight, the music will sound too lean. 

Controlling the woofer after it has been put in motion by the signal. No extra bass caused by improper 'loose' movement after the signal.

i.e. My vintage 15" woofers, Electrovoice 15W's weigh 37 lbs each, very strong spider, rigid magnet enclosure, and a 5-1/4 lb Alnico Magnet to push/pull 'tightly' control the cone.

you could have an 18" woofer with a less strong spider and less powerful magnet, but longer throw, i.e. move more air, more bass (the iron law), but it would NOT be tight bass.
