If someone would like to build a pair of HIFI -speakers
for home audio, would he better look at the newer 2227
than the 2226 when wanting a 15" from JBL that would
go as high as 1200hz ?
Or would the 2206 be the best choise, towards 1200hz
Or, does anyone have a better idea?
Why run a 15 that high? Use a 2118 or one of the 10's as a midrange driver.

Couse maybe wanting a 2-way loudspeaker..
Where do they cross the K2 s9800 ?
Uh oh, better ask Giskard again about his beloved 4430's..............Originally posted by Robh3606

Hey! Those goofy JBL 15-inch 2-ways can be fun!
These days, the 1500AL and H9800/435Be seem to work ok.
9800 is at 800Hz. The 4430 crosses at 1K. If you want to run a 2 way with a 15 fine but 1.2k is pushing it. For home HiFi I would look into a 2235 based set-up. Using either a 2226/2227 or a 2206 in a 2 way will require a sub on the lowend. JMHO

Yeah, the 1.2 kHz systems sounded almost as lousy as the 500 Hz systems. Sorry Rob, I didn't read this whole thread, I just saw Mike's post.
In my parallel universe I am currently listening to a 15" two way. I am using a 2235H up to 700Hz crossed over to one of my Westlake horns being driven by a TAD 4001.
I can't stop playing music! It is the most compelling system I've listened to in years. There are no passive components. It is a simply two way actively crossed over and the resolution is like my electrostats. I am not sure how much of that is due to the simplicity of the system and how much is due to the Be diaphragm being powered by a bigger motor than a 2440. It is something else though.

With the right 15, two way systems have the uncanny knack of sounding very real, and extremely resolving!
Its been said that less crossover points, especially in the critical lower mids are whats at work here!
My experience in audio has always been that Less is More!
I have used the 2225H in a 2 way system with an 800 Hz x-over for the past 20 years. I would not go over 1K at the cross over point. The 2425J/2370 and 3110A in a 4507 cabinet makes for a very dynamic 2 way system.
The 001 system was (and is) a cool sounding 2-way system.....
I can't pass up this thread, though I don't have a lot to offer. I just have an emotional attachment to these incredibly classic systems, 15" woofer and horn tweeter. The original Lansing Iconic was like this, with 1200Hz crossover, and it has never died.
The basic facts of psychoacoutics and physics are against you. You do NOT want a crossover in the voice range, roughly 300-3000Hz, because the human ear is especially sensitive there. But, if you allocate equal ranges (in musically important octaves) to each driver, the crossover will be right in the middle, at 800Hz more or less. A serious dilemma!
The usual solutions are single driver and three-way systems. Secondary solutions are to try to run one of the drivers over a wider range. For "serious" work, I am pursuing 3-way systems myself, and for fun I have some single drivers in work also.
But in spite of all that, for my own home system right now I personally use a 2220 and 2441 crossed at 800Hz. Sure, I hear the horn honks and the crossover anomalies, and the old 2441 is really wheezing in the top octave, and the poor 2220 isn't really giving me much below 60Hz. Don't care, I like the punch and the clarity. I have some potato mashers and D130s that I'll put together at 1200Hz someday, they will probably sound like (really dynamic) crap - and I'll love them!
The problem with the 2220, and by exension its grandchildren 2226 and 2227, is twofold - they have sacrificed the deepest bass for efficiency, and the light cone gives a rising response. Both problems can be addressed - heck, every approach has some problems; pick your favorite and work on the problems, and you can end up with something quite nice.
Looks (from the spec sheet) like the 2206 has given up a little efficiency for flatness. But it's still a high efficency 12" driver, and there's no way you'll get it down to 50Hz short of a gigantic horn. Personally, I'd work the problems with the rising response of the 15" driver - but your interests and talents may lie in different areas, and you might rather want to work the deep bass problem and benefit from the greater flatness.
I built a pair of Pi-4 speakers, a bi-way based on the 2226 or 2227, and got good results, but I agree that a subwoofer is needed for full-range.
