Is anyone in the club using an Alembic strung with a low F# string?  
 
I've got a six stringer I've been thinking of changing over and am looking for feedback. I play in church and more and more music, especially orchestral music, has me wishing for a little more lower end.  
 
While we're at it, any recommendations for a speaker that would handle these frequencies? [I'm sure the church PA wouldn't! ] I've been looking at both Accugroove and Bag End.
 
Thanks,

I assume you mean F# a 4th lower than B. WOW that's pretty low. I wonder how the string tension would be?

Bloody hell..that is LOW!!!
I think the tension would be very sloppy and would any amp & speaker be able to translate that into a useable sound??
On a keyboard it may register but a vibrating string..maybe not

would any amp & speaker be able to translate that into a useable sound
 
That was my thought on the matter as well.

A low F# is within the range of Bag End Infra (Elf) systems.

You may want to check a Conklin Bass forum (if it exists) as they make a number of 7 string basses with low F#

Or go to talkbass.com and look up JAUQO III-X

Anthony Senatore a fellow Alembic lover uses a Warwick Dark Lord with that set up. Hit him up at www.senny.com

Accugroove make a 18 sub (the Whappa Grande) for these applications. Biamped or just in parallel with an El Whappo it is mental.

+1 Dave's comment on the Bag End Infra (or ELF for the older systems). Doesn't someone make a 21 sub that might do the trick?

Loch,  
That's it. I had heard and felt it when I was at the Chicago Gathering.

The Whappo Grande is actually 21 (even better!)

This low F#  = 23.1HZ  __________________
 
THATS A GROUND SHAKER!!!   maybe a ground pounder !!!!!!

Wow! Thanks for the quick [and helpful] suggestions. I'm aware of the El Whappo Grande and the Bag End Infra/Elf systems, but never actually heard from anyone who owned played through one.  
 
I did see the low F# on the Conklin basses, but again, haven't talked with anyone about its practicality.  
 
I probably will rarely hit the F#, but a Bb and an A would often be useful, especially as they would then appear further up the neck. I typically play there.
 
Besides, just imagine how many people in church would think they heard from God!
