M6 8-inch Marine Subwoofer for Infinite-Baffle Use (200 W, 4 ohms) - Gray Metallic Trim Ring, Titanium Sport Grille

With appropriate system setup, the addition of a subwoofer allows your smaller main speakers to be free of the burden of reproducing low frequencies. This allows your whole system to play louder and to sound cleaner at all listening levels.

Purpose-engineered and built for real marine duty, the M6 infinite-baffle woofers are designed to operate without a dedicated enclosure. Long excursion capability and rugged suspension systems help produce deep, powerful bass response that will transform your boat's audio system.

The M6-8IB is best used with amplifier power in the 50W - 200W range and is optimized to operate with a large volume of air behind it (at least 1.5 cu. ft. / 42.5 l). If you prefer to use a dedicated enclosure, refer to one of the suggested designs located in the Specifications section for optimum performance.

Like all JL Audio marine speakers, this driver is built to withstand a real saltwater marine environment and deliver years of listening enjoyment.

Production of all M6 loudspeakers takes place in JL Audio’s Miramar, Florida factory, using global components and materials.

Sold individually.

USA Limited Warranty: Two (2) years from the original date of purchase.

An L shirt for a real L person.
Special Size: Standard, Size: Large, Color: Wine Red
I love this shirt! I have been an "XL" guy for decades. Got back down to "L" a year ago. Finally bought some L shirts, starting with this one. Nice fit. Good stitching, tight buttons, crisp fabric. The button-down neck is sturdy and keeps a classic shape to it after several times through the wash. Not much stretch, so buy it if you are *really* a size L. But if you used to be a size XL, and came down a year ago, get one of these. You deserve it.

Great shirt - tail could be longer - great color selection - No 1000 pins to remove!
Special Size: Standard, Size: X-Large, Color: Aroyal Blue
Favorite shirt, fits well, looks good, durable. I'd like if the shirt tail was longer. All cotton so they shrink a bit after washing and need to stretch back out. Overall, I'd like if they were a touch larger or I was a touch smaller. I love that they don't have a HUGE AMAZON BASICS label on them. And I LOVE that I don't have to spend thirty minutes removing tiny stick pins like other dress shirt makers force you to do - what a waste!

Reliable, well-made shirt with a slightly lighter color than expected
Special Size: Standard, Size: X-Large, Color: Navy, Special Size: Standard, Size: X-Large, Color: Navy
This Alimens & Gentle Oxford shirt is a solid, well-made option that holds up well over time. After roughly 20 wears and washes, it’s proven to be durable and fairly resistant to wrinkles, which is a big plus for a cotton button-down. Fit & Comfort: The fit runs a bit on the loose side, but it’s still comfortable and easy to wear. It’s not a slim fit, so if you prefer a more tailored look, keep that in mind. Material & Performance: The fabric is thicker than most standard dress shirts, which makes it a great choice for cooler weather. It provides a bit more structure and warmth, but it may not be as breathable in the summer months. On the plus side, it washes and irons well and maintains its shape over time. Appearance & Versatility: The shirt pairs well with both dress pants and jeans, so it works in both professional and casual settings. One thing to note — the actual color is noticeably lighter than what’s shown in the listing. In my case, I still liked the look and kept it, but it’s something to be aware of when ordering. Bottom Line: A dependable, slightly heavier Oxford shirt that’s great for fall and winter wear. Best for those who prefer a relaxed fit and don’t mind a small variation in color from the listing.

What A Find! Unbelievable Quality and Price!
Special Size: Standard, Size: Large, Color: Plaid-light Blue
I can't believe the quality of this shirt!! I ordered the blue checked one for my husband for a costume. The price was right and I didn't expect much, as it was just for a costume. It came packed into a little box, which I figured showed it would be super thin and cheaply made, but didn't really care as only needed it for one time. Woah!!!! I opened the box and was absolutely floored by the quality and heft to the material. It is crazy. I don't know how they get this shirt into that box, but it is baffling. This shirt is of high quality, with all the seems sewn well. The fabric is every bit as good as the brand of oxford shirt that costs 3 times the price of this one. My husband goes between medium and large. He takes 16" neck in dress shirts. We ordered the large and it fits well. Has a little room, but not in a too big type of way. I washed it once before wearing, and it washed well. Not much shrinking at all. It ironed very easily without a problem. Yes, it is 100% percent cotton. Because of the quality and fit, I will now order additonal colors. My husband loves this shirt. This is an excellent buy!!!
