That should pin you to the back wall.
I ran EN5's with S22 components for awhile.
They could hurt someone real bad.

Yup, that'll work.
[You'll be wantin' a supplemental sub or two soon, tho, I betcha....]
Not Hi-Fi, but if loud and willing to take punishment is the goal you are on the right track! You may decide to add a sub if you like deep bass.Originally Posted by joe
DONE ! The plans have changed ever so slightly but I believe I may get results that are well within design parameters for a rockin' pair of speakers .
step one: acquire en5 cabs
step two : acquire 4628b cabarets
step three : swap speakers/componentry into the "pretty" boxes , and retune the port for enclosure
step four: rotate volume knob to the extreme clockwise postion , DIME IT ! WFO !
step five : GRIN as in

No not hifi that's what the century's are for
So I can differentiate the klangfarbe of a delicate string quartet arrangement with the utmost clarity !
Yes klangfarbe goddamnit ! look it up !
No seriously I may do up a set of 250's some day if I still have
"the sickness"
Alas, I don't know klangfarbe from a hole in the ground.
[I'll certainly listen for it, now, tho....
Do you know bullshit when you smell it ?
These 2118's ain't doing much for me.
Part of the problem is probably the crappy amp I am driving the cabarets with but the 145's and the tweeters sound great !
The tweeters are intense ! had to roll the L pad all the way back .
The 145 will deliver bass unlimited in their useable range , they are very quick but not necesarilly as full as an aquaplassed cone . Anyway I like em !
I hooked up a graphic eq to get the things to sound loud without as much actual SPL . When this was done I noticed the following .
1 : the top 2 and bottom 2 faders acted just like volume knobs ! When I say "jump" the tweeters and woofers say "how high ? "
2: the 2118's just seem to be outgunned by the other drivers , they too would react when I slid the faders but not like the other drivers.
3: The 2118's always sound shadowed . No amount of messing with the eq will fix it you can only make tradeoffs .
4: I finally gave up on the 2118's and used only +1 db or so at 4k .
5: I'm hoping I'll find that one is out of phase .
6: I need a better amp .
7: If that don't do it I'll be looking for something else to replace the 2118's like maybe the 2108 , sadly they are all but unobtainable
Kinda hard to trace through the jack switching in the schematic, but looks like BOTH 2118s supposed to be outta phase with the woofs and tweets in 4628B.

I was hoping one of the 2118's was out of phase with the other 2118 but that was not the case . oh well !
What size port should I use on a 4.5 cube box (subtracting .5 for the 2118 housing) with a 145 woofer ?
BB6P suggests:
1 X 6" @ 6.88" = 33.87 Hz
or
2 X 4" @ 6.69" = 37.83 Hz
~ 700 dollars later , TAH DAHHHHH ! the JBL Cabaret V .
I could have called it the jbl cabaret 4628b en5 , but that doesn't roll off the tongue now does it ?
There is no port tube yet , sounds good anyway ! the efficiency seems to have gone up a notch or so as well .
Killer Kool!!
[How'd ya spend the $700?]
Firstly I'm sorry for doubling up on te photos ! This is the 1st time I've put a photo on this site and I messed up , it won't happen again ! When I try to edit it I perform an "illegal action" somehow so I'll let it ride .
The bill goes something like this
4628b cabaret $500
EN5 cabs $100
gasoline , 3/4 mdf ,black satin paint ~ $100
Now when I went to the wal mart to pick up a new cd of van halens 1st album for these speaks I noticed that I could have gotten a COMPLETE SONY STEREO W/ CD PLAYER for 300 ! Oh well ! I'm a slow learner I guess
It's time for phase III I believe .
The sound of the 2118's improved in the new enclosures , but they are still being outdone by the other drivers and are a little shadowed on their own anyway.
The improvement may have come from the fact that I used 3/4 mdf for the subenclosure as opposed to 1/2 in the 4628b , or it could be because they are now mirror imaged , or both.
They still seem shadowed though and I think it may be a byproduct of the mids having to do too much work reproducing signals that are just below the cutoff freq . I think maybe if I used a higher order Xover on the bottom of the 2118 it may help clear them up slightly , go to more of a brick wall so to speak .
I'll let them roll out on top ,same as before ,that doesn't seem to be an issue.
The 2404's may benefit from the lighter , more sensitive diaphragm's used in the ??? as opposed to the heavy duty unit it now has . What is the part # of the diaphragm I'm looking for ? Anyway that's later on... gotta clean up the 2118's 1st .
D16R2405. Don't worry about the "16." It's really an 8-Ohm diaphragm.
Compare the results I'm currently getting in VHF response in DIY Minis with "H-1" (top) vs. standard "H" with the lighter diaphragm (bottom).
