2309/2310

[dino]

Hello. I was thinking of building a three way system using the jbl 2309/2310 with a radian 951bepb but not much info on the roll off hf on this horn. I read about a roll off hf of 12khz but that was using the jbl 2440 driver. Will this horn extend up to 18 or 20khz. Thanks

Hi Dino,

The HF rolloff is really determined by the driver ( not the horn ).

Here's the frequency response of that driver;

You can see that it only goes up to around 12K-13K before rolling off up in the top end .

It's low end reach/range does looks good ( the low end is largely determined by the size of horn ) .

I'd be using a tweeter with that driver.
