Key Features
The 0261 is a 25mm aluminium dome tweeter housed in the distinctive oval black plastic faceplate used throughout the Profile Sixes range. The aluminium dome offers low mass and high rigidity, giving clean and extended high-frequency reproduction. Within the Profile Sixes range, the 0261 is partnered with first-order crossover networks, with the 631 and 632 crossing over at 4kHz; specific crossover points vary slightly by model. The unit is rated at 8 ohms nominal impedance with sensitivities in the 87–90dB region across the range, consistent with the full specifications of the models it serves.
Replacement tweeters for this range have become increasingly scarce. This NOS example, in its original labelled packaging, represents a direct like-for-like replacement for a failed or damaged unit in the 631, 631SE, 632, or 633, and is of particular interest to owners wishing to maintain their speakers in original specification.
