Sundown Audio - M-Series M8"800W Watts RMS 1600 Watts Peak Dual 2 or 4 ohm voice coils Optimized for small ported enclosures Aluminum 2. 25 voice coil former for superior heat dissipation High temperature copper voice coil wire Double stitched surround Carbon Fiber Cone & Dust Cap Heavy duty cast basket Spring loaded terminals accept up to 8 gauge wire Stitched on heavy duty tinsel leads High Veloctiy Vented Pole Rear gap venting 18mm one way linear x max by 70% BL The Sundown

The Sundown Audio M-8 is the big brother to the SA-8 v.3 model. Both the coil diameter and winding width are increased in comparison, resulting in higher power handling and more linear x-max. It features a Mid-Q which results in excellent vented and bandpass performance.

The specially designed motor is mated to a custom tooled and patented (US Patent D691595) frame. The smooth one-piece T-Yoke was FEA optimized for optimal flux transmission. The M-8 features a fully computer optimized spider & surround designed for low distortion and high levels of long-term endurance under demanding conditions. It features a thick magnet ID shorting ring to linearize and reduce inductance – thus reducing distortion even further. Every detail was engineered for phenomenal performance and pleasing aesthetics.

Good shirt
Size: Medium, Color: Teal 02
Love the color and the design of the shirt. The small threads it’s made out of starting to come loose though. Now when look down at chest and stomach area, there are 15+ little strings that pop out of the shirt.

Awesome shirt!
Size: Medium, Color: Blue, Size: Medium, Color: Blue
This is a nice shirt! Let me start by saying I am 6 foot 2, 195pounds with about a 40 inch chest, 42 inches on a good day! Ha ha. I ordered a medium because I wanted an athletic fit. The medium fits just right. For those wanting a normal, roomier fit I would recommend the large for my size. I’ll get a lot of compliments when I wear this shirt. What I like about it is that it is wrinkle free and looks great, I would not wear it on a super hot day with a snug fit. I do live in Florida, so that makes a difference. I also ordered the black one, both the blue and the black look very good for dress /casual. It’s polyester so it’s not super soft, which is OK. That also means it does not shrink.

Nice shirt but seems to be confusion over the color/pattern.
Size: Medium, Color: Teal 02
Nice shirt. Looks sharp and feels comfy. Lightweight and breathable. Definitely an "upscale" polo that looks like it costs more than it does - so very happy with the value. Fits as expected for the size. The only issue is that I ordered a color and style called Teal-02 and they sent me Navy-01. The color and pattern is different. It's not bad, just not what I ordered. I requested a resend of the Teal...and got the same Navy color again. Annoying.

Nice, but a bit transparent.
Size: X-Large, Color: Lake Green
I love the feel of this shirt. It is very cool and comfortable. The only thing I will add is that this shirt is a bit see-through. If I wear it, I do not feel comfortable unless I have an undershirt on.
