I have an opportunity to purchase a set of JBL 4663 Enclosures loaded with
JBL E-140 15” Woofers
JBL 2461 HF Compression Driver’s with JBL 2345 Horns
JBL 2405 HF Super Tweeters
JBL 3110 & 3106 Crossovers
I was wondering how these would sound in my family room hooked up to a recently restored Sansui 9090DB? I realize these enclosures are essentially for live band performance but was wondering if I could rock the house with these as well, and how the clarity of these enclosures measure up to regular home stereo speakers. Any advice would be appreciated as I am rather uninformed about these particular speakers.
Thanks much,
Cykotic

Yep,

Loud & Clear / just not much bass ( below about 150hz ) .

That, you'll need to EQ in .

Great! Thanks much! I'll make sure I hook up an equalizer to it as well! I'm surprised that they won't go much below 150 Hz however since JBL rates the E-140 at 40 - 2500 Hz. Oh well.
Thanks again!

There are two primary issues as I see it…

First, these are PA speakers that are designed to project into an audience. If your room isn't large enough for you to sit back 30 or 40 feet you won't be getting a fully balanced sound from the speakers. Second, the reason there is not much bass is that the horn loading boosts the bass output about 6 to 10dB above approximately 150 Hz. Below that frequency the horn has no loading and the woofer functions as though it is in a bass reflex cabinet.

Thanks, Widget. I'll take this into consideration since I can only sit back about 15 feet. Unless I put them on the other wall and then I could get 30 feet back.
Thanks again!

Ciao, I have (now dismissed for a while) a similar system...

you can live with this system at home, bass can go around 50-55hz, ofcourse not flat due to the dominant 150h-200hz characteristic of the 4560.

I would rebuild brand new crossover for a better adjustment in home application, but the original one can fit (check the LPAD).



You can Rock your house with 1-2Watt, those speakers are > 100db/w/m....

If you want Bass, Just Add some subwoofer.



Sound is clear and crispy, precise and detailed. Of course you need space....
