Description
audison APS 10 S4SPrima compact subwoofer family expands with the introduction of the new 25 cm (10 in.) APS 10 S4S, optimized for enclosures with a reduced volume starting from 10 liters. The configuration of the single 4 ohm voice coil makes it ideal to be driven by the new AP F8. 9 bit amplifier with built in DSP that delivers an outstanding 260 W RMS with two channels bridged. Also interesting is the possibility to create custom enclosures with two APS 10 S4S

Features
- Ultra-low profile (4.7 in. / 120 mm) for maximum installation flexibility.
- Designed to deliver maximum performance in a sealed enclosure starting from 10 lt.
- Special-designed cone-dust cap-basket geometry guarantees a long linear excursion capability (11 mm, one-way) while keeping the mounting depth to a minimum.
- Air vents on the basket underneath the spider, eliminating the need for the central pole vent allowing mounting close to the rear wall of the enclosure.
- Massive motor assembly, optimized with FEM (Finite Element Modeling) for perfect control under high power, high excursion conditions.
- Water-repellent treated paper 10 in. cone, featuring a profile developed with FEM simulation and optimized with the Klippel Scan Vibrometer.
- Single voice coil design specifically developed to be combined with either AF M8.4 bit (2 CH bridged 260 W RMS) amplifiers taking advantage of the bass boost feature and integrated parametric equalizer of the built-in DSP.
- Steel mesh grille and plastic gasket included. –

Good Fit Out of the Box
Size: 9, Color: Black
The shoes came with the correct size and is a good fit. They were originally pretty stiff, but are much better now after breaking them in. They look good. but as other's have said, they are made of synthetic leather and in my opinion have kind of a plastic look to them. The quality is good with ridged rubbber soles. I thought they were kind of expensive, but then again I haven't purchased these type of shoes in a while. A family member told me that if they were real leather, they would have been a lot more expensive. For what the shoes are I would recommend the purchase.

I wanted to love these
Size: 9, Color: Black Leather
These are very good looking in person, especially the buckles and the pop of red on black.
Alas, I have another pair of Marc Joseph shoes to compare comfort and fit, and this pair simply hurts my feet.
