Cab Pack “PR-H75” 是基于老式英国 4×12 箱体的脉冲响应 (IR) 系列，带有极为罕见的 pre-Rola? Celestion? T1217 Greenback 扬声器，带有重磁铁和 75Hz 铅锥。这些扬声器具有与 T1221 相同的音盆和与 T1281 相同的磁铁，因此它们是杂交经典。
Cab Pack “PR-H75” is an impulse response (IR) collection based on a vintage British 4×12 cabinet with extremely rare pre-Rola? Celestion? T1217 Greenback speakers with heavy magnets and 75Hz lead cones. These speakers have the same cones as the T1221 and the same magnets as the T1281 so they are crossbreed classics.
