@christoforos: "Hi All,
I'm looking for a midrange that sounds good, is as small as possible,  and
with sufficient efficiency and power handling to complement an eminence
delta 12 LF for bass guitar.
I'm really stumped and the nearest thing I can come up with is a B&C 6"
driver that'sjust on the low side for the power handling.
Any ideas?
Thanks.

    @christoforos: "Thanks Liquidator.
I'd prefer something a little smaller or multiples that are a lot smaller.

LV, Care to point me in the right direction for a NG for this sort of stuff?
AGA seems to react negatively to bass guitar speaker questions and there
don't seem to be a lot of people there that are into bass anyway.

That is much appreciated. There seem to be a lot of PA related questions
here which is the sort of thing that I'm after...
The Alpha mentioned is a good speaker and one I've been considering although
not in the MR package. There also seems to be a fairly uneven response in
the range that I'm after. The straight 8" or a pair of them seems to be more
like the ticket but I was hoping for a 7kHz rolloff rather than a 5kHz
rolloff - which the 12" already has mind you - hence an argument for smaller
drivers and maybe multiples of them.
Maybe here's the right place to pose the question: For bass guitar, what's
the relative power ratio required for 40-600Hz V 600-7kHz? Is there any way
of calculating that? My thoughts have been that driver and midrange should
be of equivalent power handling i.e. 400W woofer and 400W midrange (assuming
the same efficiency).
Unless the only venue you ever work is your
A new box is what I'm considering - for the midrange only I'd only consider
throwing a horn in to the existing design and I'm not too fond of those for
bass guitar.
Most bassists use a 1x15" + 2x10" drivers or similar (2x12" +2x10" for ex.)
for their primary rig these days for smaller stages and practices. The PA
IMO should take care of the rest as deaf musicians are pretty useless to
anyone. These also tend to be powered with the full range signal which to my
ears sounds wrong - especially when the bassist is hitting much lower
frequencies than his cab is tuned at. That's why I'm using a 12" that is
flat down to 40Hz - not -3db @58Hz, usable low frequency(-10db) 40Hz(Ampeg).
Where the 12" doesn't seem to cope well with reproducing my bass is above
1.5kHz where I have a small PA driver handling the upper end at the moment.
What I'm worried about is that the PA driver can't handle the power I'm
throwing at it - hence my request for more information on drivers in that
range. The delta 12 LF is a 500W driver @98dB. Other considerations making
me want to consider say a 2 or 4x5"-8" enclosure are off axis sound levels.
LV, are you a little more civil round here? It's sure to chat on this tone
with you. No matter what you may think, I have no beef with you.
Thanks.

Well, cheap is relative. One suggestion I had was for a pair of $450
midranges (that's each!) - realy out of order. Sub $100 for a driver pair
I'd jump at, $200 for the pair and I'd be very very tempted with some good
recs.
Agreed! Also thanks for pointing out a couple of things that I didn't
consider. My 12" has a active low pass filter before the amp set at about
400-450Hz. I'm using a tiny (3 1/2") fullrange for practice with it at the
moment that I'm scared I'll blow if I put any serious power through it. I've
set the crossover by ear - where it sounds sweetest slightly off axis
looking at my 12"  with active crossover, I was thinking to myself that
2x10" cabs don't really shake the bottom end much - probably because of a
high Fs and 60 something Hz tuning frequency that makes the drivers have
that bit less control at the bottom end. Instead of getting myself a 2x10"
and getting a case of the flabs, I thought that I might let the 12" take the
full bottom as it's doing now and get a 2x something smaller in a separate
cab to handle the midrange and get even less beaming.
I'm really wondering how I can check for power content above say 600Hz with
my bass. I guess an RMS VU meter will do the trick and then compare values?
vary.
It's probably close to my best bet.

I'd probably want the non MR version for a smoother response as I have to
build another cab anyway for it. the 12" will end up having a tweeter at
some point though.
Thanks.
