Suggest me a build using 2226J's

post #1 of 42
Thread Starter 
Criteria:

pair of speakers
JBL 2226J's (have a bunch of these already so don't say H's)
economical ($150-300 tops)
2-way design with compression driver and horn
passive or active - I have a Rane AC-23, not the best, it's good enough, or perhaps a passive kit (i don't have time or skill to solder all that stuff)
cabinet can be ~20" wide and 26-36" tall as needed
prefer sealed, they only need solid output to 40hz since I have an IB subwoofer
will be powered by my Parasound HCA-1206 (125 x 6), could also use my Dynaco ST-70 for the CD in bi-amp

thanks

I know this is a little bit big but what about something like the JBL 4675?

Dual 2226j's to reach an 8ohm load, under a horn / cd .

WHY / WHERE did you get a bunch of JBL drivers ?
post #4 of 42
Erich H might still have 2226j's. OP, there is a SEOS-12/ 2226J/ DNA-360 or DE250 crossover done already.

Those JBL's would be ridiculous for a TWW 2.5 way tower with a SEOS 15. That's what I would be building if I somehow acquired a bunch of $500 woofers.

Or you could do a Pi / De250

He has 2226j's not H's. Has Wayne done a crossover for that ohm?

Apparently he's had some people who've tried.

Seems it would work but hasn't been tested fully. Probably better off with the SEOS design.
post #10 of 42
I plan on building a trio of Seos-15/BMS-4550/JBL-2226 for my theater room. I think that would be a giant killer when it comes to movies.
post #11 of 42
I'd love to see a stacked MTM design using two 2226s and something like a SEOS 15. That would be monstrous.

be a task big or small...

you might drop a note to wayne parham
and ask if has a crossover worked out
for the -j. i don't know if he has or
not, but i wouldn't be surprised if he
has or knows of someone who has.

Wow, the sensitivity on those have to be incredible.

Thanks for the advice. The SEOS-12, DNA-360, 2226J combo seems good for my needs.

So the costs would be about

SEOS-12 - $28 x 2
or
SEOS-15 - $60 x 2

DNA-360 - $75 x2

What crossover are people using for this or does everyone do active crossover?

What advantage does the larger SEOS-15 have over the 12?
post #16 of 42
For the crossover I believe that Wayne Parham has developed a passive for the 2226h for use in his 4pi, but I am not sure if he has developed a crossover for the 2226j. There have been a couple of builds using the Seos-12 and the 2226h.


The main benefit for the Seos-15 over the Seos-12 is that it can be used with a compression driver that is crossed lower than the Seos-12.
post #17 of 42
I did the SEOS 12 / 360 / 2226J with Brad and also looked at the files for the 2226H with Matt. I can help you with the passive XO and give you active settings as well if you'd like. Since you already have an active dsp and all.

I would prefer a passive design for future simplicity - so the speakers could be used on any receiver without extra gear. How hard would it be to assemble the crossovers and about how expensive?
post #19 of 42
Do you have soldering experience. ? I can help walk you through it.

The parts will probably cost around $30/speak.

I bought 6 from Eric's big driver sale. Only using 1 pair but one day I'll make 6 speakers out of them.

I can do basic soldering. My friend could probably help if there is anything more complicated.

Thinking about it though, maybe I would like an active setup. I like the flexibility and control. With passive it has to be pretty much right and all you can do is tone controls or nasty EQ.

If you have the spare amp channels, and a devise to use as the active crossover, then I say go for it! But if it were me, and I was going to go with the added cost and complexity of an active setup, I would
recommend that you wait and get a Seos-15 in leu of a Seos-12 as I believe that with an active Seos-15 setup you can squeeze out a little better performance, sound quality wise.
post #23 of 42
Not bad advise. If you're desparate to build today, then active setting and passive cross over are already done. If you can be patient and wait for tomorrow, the SEOS15 should be done fairly soon and would likely be marginally better. You'll have to wait for cross over work to be done though. So I'd say you should expect to wait 6 months...

Given that the 2226 rolls of relatively smoothly it really isn't that hard to get it right. It has been done in many, meaning tens of thousands, 2 and 3-way systems.

Just build it! wink.gif

Would you guys bother with a 3-way setup? I have four JBL 127H drivers (10" woof)
post #27 of 42
Not with the 127H. If you had 2123 or 2012's I'd say yes. I used a 2225/2123/Ewave CD and DE250 system for a while, all active and I thought it was terrific. It was in a much bigger room than I use now so the dispersion not being controlled quite as low wasn't an issue. I use an almost identical design for my surrounds now, but using AE drivers instead of JBLs.

With what you have an active 2226/SEOS15 looks pretty good.
post #28 of 42
If someone was going to build some mid-bass cabinets with the JBL2226, what would be a good enclosure size and what would be a good way to power and implement them with an existing monitor setup? I would assume that using a plate amp with speaker in/out's would be a good way of doing this?
post #29 of 42

Marty-

that's my franken-setup now. I have a single 2226 in a cabinet about 20" square crossed at about 250hz to my JBL 8340's sitting on top as mains. They each get a channel of my parasound 1206, so the 2226's get maybe 75 watts since they are 16 ohm. Volume capability is still ample with the high sensitivity.

Jesse, how do they perform in this situation?
