which 10" drivers

[subwoof]

I have one 4688 sitting in storage taking up space and know of 2 more available nearby. ALL are NOS but have minor moving around scratches. they were purchased from JBL at the *first* sale in 1997.

I have a pair of K151 ( alnico mag ) with new 2240H kits installed and would be willing to sell it loaded. I have a mini-van and can travel a few hours to meet. PM with email address if interested - NO tire kickers please.

Nogo on the tech note ( yet ) my library stops at 15 then goes to 22 in the vol. 1 series. I *know* I saw it somewhere....

I can do plans but other projects prohibit the time. The box is not that complex.

I would LOVE to find the dual 15 version of this to make dwgs from..... anybody know of one???

did not expect the wealth of info ...seems like my project is quite feasible, but maybe not in the volume enclosure size i want. may just have to go with a single high powered 10" in a reflex design. i'm still sticking with 10's, i have (4) 2241's vented gap in dual 18" cabs (sold to facilitate this project)...sound great but, they are huge...this is a home application.

just for the record, sound is a multifacted thing...you can't know everything. my forte is mixing...been a pro sound engineer for 20 years (semi retired...or maybe i'm deaf!) though speaker design is merely a side interest i have built many systems using simple bass reflex designs using JBL drivers as my "B" system. i thought they were better and certainly more durable than the "turbosound" designer system i had, which set me back $4,000. x 16 boxes...but, contract riders are the rule or you don't work.
now i'm down to a pair of 4412's and the original century 100's which started this obsession 32 years ago...thus the sub.
my past inventory:
(2) L100
(2) 4412
(2) 4425
(4) 4663 3way (2205/2470/2x2405)
(8) dual 18's (2241)
(8) dual 12's/2" (E120/2241/2245)
(4) dual 15's (E140's)
(4) single 12's/1" (E120/2420)
(11) 4602 stage monitors
(1) dual 15"/2" drum fill (E145/2441)
...maybe i should have bought a house instead

You could find some sub1500's and put them in a 2.2 cu ft sealed box and (rock) out!

Or maybe a warehouse. Someday you'll need that room.

Yeah, that's a more "practical" size:

4682 = 23.5 x 39.25 x 20.75 (Think "B460")

4685 = 29.5 x 49 x 20 (Think "dual B380")

4688 = 29.5 x 59.2 x 29.5 (Think "refrigerator")

[I now notice that tuning frequencies are actually given on the data sheets. ]

O.K., who's got access to ANY of these they can make drawings from, please?

I take issue with a couple of assertions there:

1) That "Push-push" arrangement "reduces mechanical stresses and minimizes third harmonic distortion through cancellation of nonlinearities." Isobaric "Push-pull" arrangement (4 drivers) would do that, which this ain't, or alternative mounting of 2 drivers could, as well.

2) "High performance in a compact size." Yeah, well, compare to 4645C.

[I am not deterred, tho.... ]
