The M6+
* The M6+ (cast alloy red frame) has a more massive voice coil than typical bass/midrange and leans toward the bass in the sound compared to the standard high-end mid drivers. The upper midrange is somewhat mellower than standard high-end mids which creates a very very smooth and balanced non-fatiguing sound with an extension in the bass region never heard of before from a 6.5 mid driver.

* Sensitivity: 83.8dB
* Maximum Power Handling: 240 Watts Peak
* Nominal Power Handling: 120 Watts RMS
* Frequency Response: 10~4000 Hz
* Nominal Impedance: 4 Ohms
* Voice Coil Diameter: 1.5"
* Peak Xmax: 12mm
* Magnet Weight: 30 OZ
* Surround Material: Rubber
* Frame Type: Cast Alloy
* Cone Material: Fiberglass
* Mounting Depth: 3.37" (top mount)
* Cutout Diameter: 5.812"

And if you don't get the whole specs of the speaker, the + has a bigger Xmax which means I think it can produce moar DBZ

... no it's not. stfu.
The M6+ has a larger voice coil diameter and a larger Xmax which means it has a bigger excursion. So PLEASE stfu

The M6+ has more output and the capability to get lower than the M6. However, for best performance it needs to be run sealed. The M6 is better suited for a regular door install. I do not recommend the M6+ for use in a 2-way set (unless you're using an ES-02 as a tweeter) as you'll be losing some midrange. Its best use is in 3-way sets or as midbass/sub driver.
