Extra Info: First owner, bought the pair new some three years ago. These are the low-impedance, low cone mass version of the L26 subwoofer/woofer driver that's suitable for both home theatre and music duties. I really like these as they have decent oomph but are not impossibly large. Don't be fooled by the subwoofer-wise diminutive 10-inch size, a pair of these will shake the slab in our house when Tom Hanks arrives on board of the Polar Express... extremely stiff aluminium cone and subber surround ensure cone break-up modes are both well controlled and north of 1 kHz, so also could be used as the low-frequency drive in a 3-way or 4-way set-up. They're not claustrophobic either, will happily reside in a sealed box of 40 litres internal volume, one of which can be offered as an option for the preferred local pick-up, in a beautiful (!) raw mdf finish; the model ship or the alarm clock are not being offered as part of this deal. I do have the original boxes so could ship these, however they are something like 12 kg a pop when packaged. Could arrange drop-off  in Geelong area or western suburbs of Melbourne.

 

A couple project builds where this driver is used:
