The '412 HWTT BOXY CONBINATION' is an impulse response product based on the HIWATT™ SE4122 speaker cabinet equipped with the rare and vintage Celestion™ “ROLA” G12H30 Blackback speakers, renowned for their exceptional quality.

Refers to a specific technique in guitar amp cabinets where different types or models of speakers are alternated within the cabinet. It is sometimes referred to as the X-Pattern, as in the case of the Bogner Uberkab™. Generally, this method combines the unique sound qualities of each speaker type, producing a richer and more diverse sonic experience.

This cabinet IR exclusively records with mixed microphones to replicate the combined resonance of different speakers. It does not include single-mic IRs, which are available in a separate edition.
