The APS 8 D is designed to deliver maximum performance in a sealed enclosure with ultra-compact volumes from 7.5 lt. to 8.5 lt. It features push connectors for ease of wiring and configurations and has been developed with a primary goal: to deliver high output in tight spaces. Output is a matter of excursion; the more air the cone moves, the more output. However reduced mounting depth traditionally has meant low excursion. Prima subwoofers employ a special cone-dustcap-basket geometry which guarantees large excursion of the mobile group, while keeping the mounting depth to a minimum. The surround and spider have been carefully designed to prevent the rocking-mode phenomenon. The cooling circuit has been designed with air vents on the basket underneath the spider, eliminating the need for vents on the bottom-plate. This allows the subwoofer to be mounted close to the back wall of the enclosure, making the most of the reduced mounting depth.

Does the job but dangerous to walk with!
Does the job but dangerous to walk with: foot is sliding inside the sock if the foot was treated with cream or lotion prior. It is uncomfortable to sleep with but a necessary hurdle to heal your heels!

The really work!
Bought these or a friend with severely dry cracked feet. The change was significant and immediate. They wore them around the house for a day and that night they could already feel the difference.
