JBL M2 Vs 4367

It is hard to find amp to run M2 that is quiet with out selling my legs and arms :/

The JBL M2 is essentially a PA speaker priced higher for the glossier cabinet finish perhaps.

If the main goal is sonics, the Yamaha CZR12 (~2k/pair) or the Pioneer XY-122 (~4k/pair or lower) are really well engineered, incredible sounding speakers, for a lower price. The Pioneer XY series has some TAD hands in it, but without sky high TAD prices.

You should be easily able to find an amp for these without selling your arms and legs. Get any hifi-ish amp, 100W/channel @ 8 ohms, clean class AB. Try something like a Schiit Vidar.

P.S.

The minute you let audiophiles anywhere near speaker, price will go up. Some of these secret high performance speakers with affordable pricing stays with the Pro Audio guys. Just don’t tell too many audiophiles about it.

My guess is that the active crossover for the M2 includes protection circuitry which makes it safe to power them with 1200 watts. For instance the woofer is probably protected from damaging over-excursion caused by high-power signals below the port tuning frequency.

And my guess is that 300 watts for the 4367 is a conservative rating, quite possibly based on the excursion limits of the woofer rather than on the thermal power handling of any of its components, including the crossover components.

Good advice.

The 1,200 watts JBL M2 "rating" is really a reference to the Crown iTech5000HD power amplifier (with built-in DSP), that’s intended or certainly recommended in pairs for use with the M2’s actively, and which is power rated at 1,200W into 8 ohms.

The important takeaway here for using such powerful amplifiers in conjunction with the M2’s (who’s continuous power handling, like the 4367, is ~300W) is both for the reasons to maintain headroom as well as the nature of dynamic power delivery and handling. Also, their intended use professionally will necessitate higher SPL’s for longer durations, and so effortless delivery is paramount.
