2440 level reduction

[MikeM]

Hello all, been a few years since Ive checked in here.
New purchase (off ebay) Maybe you seen these a couple of weeks ago Here http://www.ebay.com/itm/JBL-PRO-TWO-...p2047675.l2557
Anyway these are pretty cool, 3115b Crossovers along with a 7K crossover. Take a look at the pictures on the post please. I need to reduce the output of the Compression driver 3-6 db. How could I do that?
Cheers
Will you believe that there is NO insulation in the cabinets?
Mistake these are the 3115A versions

First, looks like it may be a 3115 (no "a" suffix, and I'm not aware of a b version)

Next, you've turned the attenuation knob to note changes?

You could add an L-pad between the crossover and 2440, or an equivalent pair of resistors to knock the level down without changing the crossover frequency (or in-band response much).

fun set of parts and nice price

Thanks for reply, Yes they are the 3115A version. Crazy the picture don't show that but there is the 3 way toggle switch on there. So there is a 3 way switch in addition to the rotary switch. Like to still reduce the output a bit. Id dig into the crossovers and swap out a resistor so the toggle reduces the output a touch more.

Ah, couldn't see the switch.

If I recall correctly, that switch throws in a compensation for constant directivity horns, which you shouldn't need.

That said, the options are pretty much what I said before.

Many Thanks for the help! Would these be a good starting point http://www.ebay.com/itm/L-Pad-100W-M...YAAOSwd4tUBzo6

That's what I'd be looking at.

The incorrect knob on the crossover with the three-way switch is confusing. The four-position knob is used for the variable L-pad, not the three-way switch.

[grumpy]

Yup. Kinda assuming that had been tried.
If not, good time to try before spending $ on additional attenuation.
