50 ounce H (heavy magnet), 55hz bass response, 12 inch special design aged cone, small dust cap with vintage correct doping, spider, and voice coil tolerances. A close recreation of the 444 bass cone, with the more aggressive lower & upper midrange and sharper highs this speaker produced. This speaker is very similar to the tone produced in the checkerboard cloth Marshall cabs of the mid to late 70's. These speakers differ from my pre rola speakers by having a more aggressive upper midrange tone, with a bit more upper mids, and not quite as dark as H55's. Awesome for players who want a bit more bite.

50 ounce H (heavy magnet), 75hz bass response, 12 inch special design aged cone, small dust cap with BlackBack era correct doping, spider, and voice coil tolerances. Aggressive, detailed midrange enhanced guitar speaker with cutting overdrive and distortion tones that have more bite than the H75 series. Great sound right out of the box due to factory aging, design and break-in procedures. This is a superb tone and sound recreation of the G12H30 mid 70's era "Blackback" that was used in Marshall checkerboard stacks and combos, and many other British amps of the era such as Vox, Orange, Sound City, etc.

Same speaker as the BH75, but with a large dust cap. The large dust cap smoothes out (rolls off) the highs, and makes the treble silkier on the top end, and adds a bit more bass response, right between the BH75 and BH55 models. The large dust cap model is similar in tone to a G12-80, but with a more aggressive upper midrange response. It also handles higher gain better than small dust cap speakers, making it great for hard rock, and 80's hair band styles.
