Single 20" T39 first Time Out

[biodad]

Greetings

Saturday I performed a casino room that was pretty big and packed out. I used one 3012LF loaded 20" T39. Got one more to build yet.
This is not your typical casino, here we have to pound a bit and get them dancing. We are a dueling piano team. One T39 now replaces two front loaded eminence 18" thiel small subs. This review speaks more to the quality of tone and how dang low it seems to go, and how light and easy it is to move. The tone was a "soft and open" deep, not a "hard boxy" deep.

I had the T39 about 14 inches from the back wall about 7 feet to my side facing in at about a 45 degree angle. That sounded best throughout the room. At set up my partner played for about 20 minutes while I walked the room and checked the placement options. Corner loaded was louder but my partner sits there. Side walls at this place are booths and stacks of extra chairs and are not an option.

I am a synth programing fool and run a split point on my 5 octave synth which gives me 2 octaves of left hand piano for bass. On a couple songs I shift these 2 bass octaves an octave lower. Granted I wasn't hearing the fundamental but as one reviewer mentioned, it sounds like a freight train. On the swing section of the song "Shout" I do a walk down from "D" (one whole step below open "E" on a bass guitar) to "D" an octave lower ( 2 "D" notes below open "E" ) and back up. Nice effect. On the 2 songs I shifted it that low, people were looking at me like "what is going on". They may have never heard anything live that low and evident. I ran the T39 from 40 hz to 100 hz. I think 45hz is recommended but we weren't anywhere near pushing this thing so I knew it was safe.

Sometimes we do weddings and fire up DJ music midway through the event. Short of a million pound refridgerator sized sub that costs too much, the 20" T39 will replace or beat any sub you can purchase from a typical music store, just as others here have said.

I'm not seeing any work coming up soon where I'll pound this thing but when I do, I'll brickwall it and may post an update. I can see why folks say a small T39 crossed to a decent mid / high bin is great for bass guitar. Bill has birthed a great design here.

I can't even begin to explain the horrible imagery this invoked .
