The easy way to do it is to just use a 12Ω resistor in parallel with the driver, then use an 8Ω L-pad.

Can I also use a T-pad where I use the source impedance (amp) as say 8 ohms then the load impedance as 16 ohms or 24 ohms and compute with 15dB attenuation?
I wouldn't bother with a T-pad.
I would do the 16Ω L-pad, adjust it with test equipment, and then fine tune it by ear, then measure the resistances and replace with fixed resistors.
Calculators and test equipment get you close, your ear gets you the rest of the way.
