SET (2PCS BULK) WOOFER 165MAdditional Details AP 6. 5 ohm2 woofer has been developed with 2 ohm nominal impedance with the purpose of exploiting all the power made available by the AP8. 9 bit amplifier capable of 65W into a 2 ohm load. To maximize the woofer efficiency achieving 95 dB, a 25 mm diameter 10 mm winding height coil, so a more lightweight coil, has been employed, at the same time also providing a linear excursion 2. 8 mm higher than the one of AP 6. 5 (4 ohm),
Additional Details
AP 6.5 ohm2 woofer has been developed with 2 ohm nominal impedance with the purpose of exploiting all the power made available by the AP8.9 bit amplifier capable of 65W into a 2 ohm load. To maximize the woofer efficiency achieving 95 dB, a 25 mm diameter 10 mm winding height coil, so a more lightweight coil, has been employed, at the same time also providing a linear excursion 2.8 mm higher than the one of AP 6.5 (4 ohm), therefore ensuring high SPL values with minimum distortion even at high listening levels. To extend the woofer's frequency range down to low frequencies up to 50 Hz a 75 Hz resonance frequency has been chosen, achieving excellent low frequency output even without the use of a subwoofer.
Features
- 2 impedance, to fully exploit the 65 W power per channel at 2 of the AP8.9 bit amplifier.
- 75 Hz resonance frequency, to extend the frequency range down
to low frequencies up to 50 Hz and increase the SPL in the low range. - 25 mm mobile voice coil to maximize efficiency achieving 95 dB.
- 10 mm winding height mobile voice coil to increase maximum
linear excursion up to 2,8 mm and minimize distortion, even at
high listening levels. - Water-repellent treated paper cone, featuring profile developed
with FEM simulation technology and optimized with the Klippel
Scan Vibrometer. - Reduced mounting depth, providing ease of installation in OEM
placements. - TPU (Thermoplastic Polyurethane) surround, featuring the exclusive “Triple Wave” shallow profile, for maximum excursion linearity.
- Compact basket, protected by abrasion-resistant and scratch-proof
coating. Damping epoxy glue provides perfect coupling with the
motor system. - High current fast-on terminal with double contact on positive and
negative poles for high flexibility and quick connection. The terminal
features a temperature resistant plastic cover, protecting it against
accidental short circuits. - Developed with the KLIPPEL suite.

Good sock but thick
Color: (001) Black / Black / Castlerock, Size: Small
These Under Armour socks are high quality and definitely durable, with great cushioning and a solid fit that stays in place throughout the day. The material feels supportive and they hold up well after multiple washes without losing shape.
My only minor downside is that they’re thicker than I expected. They feel more like a heavy-duty training sock, which is great for colder weather or intense workouts, but a bit bulky for everyday sneakers or warmer days.
That said, the quality is excellent, and if you prefer a thicker, more cushioned sock, these are perfect. Just something to be aware of depending on how you plan to use them.

Black Under Armor Socks
Color: (001) Black / Black / Castlerock, Size: Medium
They fit perfect. I bought them for my
Boyfriend & most pairs are too big or not
Really no shows like they say. If they have white ones, I will be purchasing more.

Fits well! XL is Real!
Color: (239) Elite Beige / Elite Beige / Halo Gray, Size: X-Large
As far as I know, these are the only XL no show tan socks on Amazon that actually fit a size 14 foot. I've tried a few other that don't fit after wearing them once. This is a regular feeling sock and not the thin hose type like other XL.

Awesome socks. Has little gel pad on top of heel for no slip. Thin and comfortable. Previously Purchased at Nordstrom rack and no longer in stock. Happy to find here
