Need a Freq. REsponse Chart for a 288-16K Driver

[Cut-Throat]

I am constructing a Crossover and would like to see a Freq. Response Chart for a 288-16K - I am using 1005B horns on them.

The specs say 500 - 15,000 - But I was wondering how they measure.

Thanks in advance.

Altec rarely included a response chart on HF driver data sheets. The problem was; many driver/horn combos are possible. Here is a graph of the 288L on a MR94B horn. It should give you a general idea of the 288 response . . .

Cut-Throat, be aware that unequalized plots of drivers on constant-directivity horns (like the MR-94s shown) display the inherent falling HF response that won't show in on-axis plots of the same driver on non-CD horns (or EQd CD horns).
