Yep, the Reverb
Injection is a very cool thing. I insisted in the past that it is practically
impossible to get good sound under 40-45 Hz in a listening room less than 600
sq feet. If you do have a very large room, then it is very hard to properly
reinforce the room with LF, and it hit a whole other set of problems. So, the
best result is to have a moderate size of rooms, let's say 500-600 sq feet with
Reverb Injection. We need a reverberation time of 60hz to fade to the
background level (or let sat -60db) to be somewhere around 1.5 -2.5 seconds which
would be over 2k-3k sq feet with sealing of 14 feet. It is VERY hard to get
good sound in this room size.
I usually laugh
at the “big-name reviewers” who report a “stunning” bass from a new turntable, cartridge,
or new loudspeaker of the month while they are sitting in a listening room with
0.5-second reverberation. It is like discussing a “great bass” with my local
guy who does car audio. He uses a 10” hard-rubber suspended, long throw drivers
in ultra-small enclosures and drives them with 3-5kW of power, and he is
listening to it in a car with reverberation time under .01 second. The “big-name
reviewers” also idiotically staff the rooms with ridiculous sound absorbing
room treatments that eats the reverberation time even further. The sad part is the
speaker makers very intentionally make their product work in exactly this type
of environment, and the “big-name audio opinion makers” do not even understand how
far they are from any sensible bass on audio. I assure you that practically no “big-name
reviewers” understand what bass tone is, and the only thing they know is what is
bass sound pressure. Proper audio bass is a very difficult subject, and it could
not be approached by the morons whose objectives in audio are just to move UPS
boxes at warehouses.Rerurn to Romy the Cat's Site
