AF companion amplifiers are designed to add powerful amplifier channels to AF bit processor amplifiers. A plug-and-play signal input harness is included to make connection to AF bit amplifiers straightforward. AF companion amplifiers are also perfect for use with systems controlled and managed by a standalone bit processor, such as a bit One HD Virtuoso. AF companions have a “straight wire” architecture, without analog preamp functions such as crossover filtering, and are intended for use with external processors. AF M4D boasts four high-fidelity amplified channels 90W x 4 @4?*, 150W x 4 @2?* with the audiophile sound of the latest generation Audison D-Class technology. Higher switching frequencies, steeper filtering, and higher-tolerance components deliver sound above and beyond the expectation of Class D – in an amazingly compact package! The audio band is extended up to 40 kHz earning the coveted High-Resolution certification. Bridging channel pairs results in 300W x 2 @4?*, guaranteeing flexible and powerful performance.
*Output Continuous Power (RMS) @14.4 VDC, 1% THD, all channels driven.
*Output Continuous Power (RMS) @14.4 VDC, 1% THD, all channels driven.

High Quality - Great Price
Size: Queen, Color: Blue
Great sheets. They are soft, wash up well, fit as stated. The fabric makes it easier to make the bed. I would recommend to everyone.

Maybe a bit short on sides?
Size: King, Color: Blue Chambray
Really soft, but the sides are short for a king size bed. Plenty of length. So I’ve had to turn it sideways. Maybe it got sewn wrong?

Wish the sides were longer
Size: King, Color: Blue Chambray
I love jersey knit sheets. They are comfortable in all temperatures. These do not disappoint particularly for the cost. Unfortunately the top king size sheet is too small, with only just barely enough drop, on the sides. Length wise they are fine.

Very Comfortable but NOT As Expected for Multiple Reasons
Size: Queen, Color: Teal
I purchased my first Briarwood Home Jersey Queen Sheets June 2018 and was very pleased with the quality and how comfortable they are. The 2nd set I recently received (Oct. 2019) is VERY inferior compared to the first set. So inferior I would consider them defective. The fitted sheet is very very small and "barely" fits on my standard queen mattress regardless of which way I turn it. This was not an issue with 1st set. I have to really pull hard in order to get it to fit over my standard queen mattress. Luckily I don't have a pillow top mattress otherwise it probably would not fit at all. Plus, it's so tight the fitted sheet does not tuck under the mattress. Very surprised since the 1st set I have had no issues. Also, the flat sheet is MUCH smaller compared to first set. only about 3" hangs over side of mattress where other flat sheet hangs almost to bottom of box spring. Minor observation; the 1st set had a Briarwood Home tag on outside of pillow cases. The 2nd set does not have that tag. I also want to add that these seem thinner than the first set since I can see mattress cover through them and pillow case cover,,, but the translucent appearance could be because the 2nd set is white and the 1st set was teal. Overall VERY disappointed. I was going to order a grey set but WILL NOT due to these issues. I did email the Briarwood Home customer service today and hope they offer a resolution. NOTE: The customer service phone number goes straight to voicemail and then states the mailbox is full. This is the 2nd time I tried calling with same results so your only option is to send an email. I find that to be suspicious. I will update when I hear back,,, or don't hear back. UPDATE 2-13-2020: NEVER RECEIVED RESPONSE FROM BRIARWOOD. I WILL NEVER ORDER SHEETS FROM BRIARWOOD AGAIN. INSTEAD, SINCE THE 2ND SET OF BRIARWOOD SHEETS BARELY FIT MY STD. QUEEN BED I ORDERED ANOTHER SET OF QUEEN JERSEY COTTON SHEETS FROM: Road Trip America Cozy, T-Shirt Soft 100% Organic Cotton Jersey Knit, GOTS-Certified, Solid Color Bed Sheet Set (White, Queen). They have not arrived but I will provide a review after I receive them.
