25W/8565-00
In common with other Classic range bass units, this woofer sounds very smooth with good bass extension.
The Paper/Carbon fibre composite cone has a high internal damping factor and gives a very natural uncoloured sound.
Used in various mainstream and many DIY designs across the years.
Ideally suited to larger 3 way systems. Low Fs of 20Hz.
