125 | 40.5 | Improved TL at low-bass range |
160 | 39.0 | Slight dip, but still good |
200 | 39.7 | Stable response in low-mid range |
250 | 42.6 | Strong performance starting here |

1000 | 42.0 | Slight drop, but still good isolation |
1250 | 44.9 | Rebounding TL values |
1600 | 46.0 | Peak TL, excellent mid-to-high frequency blocking |
2000 | 46.5 | Strong performance continues |
2500 | 46.5 | Consistent with mid-high isolation pattern |
3150 | 43.3 | Slight dip, but minimal effect on STC |
