That last letter usually indicates the impedance.

My guess would be that they are the same driver, but the -H has its voice coils connected in parallel instead of in series as used in M2. Parallel connections of the coils would give ~8 ohm impedance, or -H as JBL likes to call it
Hi Zeljko,
It seems to that , even passive network can be applied to Your D2&M2 combo, using RLC network with Q ( =XL/R) about 0.5 with resonant frequency fo=3.6kHz, reducing sound level about 10dB on that frequency, so "only" proper serial resistor has to be calculated.
