Eminence Delta LF's were the standard for high end bass cabs for a long time. These days the Eminence drivers of choice for bass cabs are the kappaLites 3012 LF,3015 LF and the 3015 for a 'vintage' bass cab kinda thing.  I do have a very small, over stuffed ported 1x10 with a delta lite 2510-ii. Voiced deep, super small and volume limited.  Jazz gigs with a fretless ABG.

I have heard a 4x10, canted baffle with the 2510-ii that was pretty nice.  Light, loud within reason on and   a nice cone rolloff...

IMO - very important to remember. Unless you just want to mess with me at FOH, the sum bitch is a MONITOR...  Ok, backing off the caffeine and preaching to the choir ;-)

Adam,

The Eminence bass guitar speakers have about half the Xmax (only 3-4mm linear excursion) so will start to distort at about 6 dB less SPL than many their pro drivers. While that may be a good thing for "growl", you can easily put harmonic distortion in with your tube pre, but you can't take distortion out.


Art

In reality the basis for any 10" bass cabinet type driver.  It's "the sound". 

One rig I rebuilt for a workmate waaaay back at Intersonics(with some input from Tom Danley, who also plays bass on his days off) involved tearing apart a Peavy rig that used a BW 18" and a pair of 10" Scorpions.  We came up with a bandpass design for the 18, and a waveguide for the dual 12. It all wound up a tad larger than the original rig, but it went at least a half octave lower, and had some real "punch".  It was really only good at large bars, and he had to tone down the low end most times anyway as it was "scary".  Might of overdid that one...;>)

Best regards,

John

Haha. Who would have thunk it?

Those Faital 10s are really expensive!

Yep, but they're some of the best in the business. If I was going to do a "one cab forever" build, it'd be a pair of those Faital 10"s. I've used them as the midbass drivers in my main PA system for years, and they never fail to impress. Despite having a kilowatt per driver on tap, the amplifiers have hit the limiters before the sound turns bad from over-driven speakers.

That's a very good point to make.  If it's a show with a real PA including subwoofers, then it's much better to go with a small bass amp onstage and let the subs do their magic. 

You know that thing about how the bass is always louder in the audience?  It's not because it takes distance for the "long wavelengths to be heard" or similar BS.  It's because out of all the loud things onstage, it's only the bass that really couples with the architecture and carries out into the audience.  Everything else is more immediately affected by the inverse square law.

Bingo.
Any show bigger than what a 2x10" cab would manage should have a proper PA and monitors.

I dunno, Scott.  Somehow I think Jim Marshall "repealed" the inverse square law for his 4x12 cabinet... If you're on axis - at almost any distance - it's too damn loud... except for the guitar player who'd like "a little bit more".

I always tell them "If you want to hear your guitar on the board tape, don't point that thing at FOH..." :o

Almost verbatim part of my standard introduction to a new band. Comes right after “We’ll put shields in front of the (guitar) amps and close mic them”.  If the bassist seems interested I’ll go on to explain that the $20,000 worth of 2” & 4” acoustic panels they see everywhere are transparent to bass frequencies and that they’re essentially playing in a concrete corner.  Some seem to care.

You have to have it loud for the knee-to-ear bone conduction to work. ::)
