New Mid Bass (mod rod pt. 2)

[GM]

It depends on the max power it will likely 'feel' since these horns at a ~220 Hz cutoff are way too short for true 300 Hz loading and barely long enough for their 500 Hz measured ratings [1 WL effective path-length]. Ditto 300 Hz multi-cells.

In short, the 300 Hz rating is about pattern control [polar response] over a wider bandwidth [BW] to a lower frequency [Fc].

Edit: My [failing] memory caught me out. Went back and pieced together the [assembled] dims and all the [3] suffix multi-cell horns have sufficiently long path-lengths for the claimed 300 Hz rating.
