Stitched-on double “XL” tinsel leads
This SA-10/12 v.3 series is the next generation upgrade to the v.2 series. We stuck with the 2.75” coil diameter and added another 5mm of length for additional linear x-max (22mm now). We are able to perfectly balance the mass, motor force, and suspension stiffness for the intended power level. Compared to the v.2 the v.3 features taller cones and wider spiders to enhanced linearity and coil stability to the next level. We also utilized full 3D FEA to further optimize the spider packs for this generation.
The motor also features a large magnet shorting ring (faraday ring) & pole cap faraday ring to reduce distortion and deliver smoother response across the entire acoustic spectrum. With the v.3 upgrade we integrated a completely "locked-in" faraday ring that is physically held in place by the T-Yoke. The motor & coil setup is mated to an extremely robust multi-layer spider with fully tied-on & doubled-up “XL” tinsel leads. A competition-grade paper cone, strong foam surround, and custom-tooled aluminum frame (same frame as the bigger brother U v.2 series) are used to complete this masterpiece. On top of the ~22mm of one-way linear excursion we have an x-mech limit of 41mm one-way before coil bottom making it nearly "bottomless." The new motor was designed as a "little brother" to the U v.2 series so you will also note the updated venting system with a solid pole piece from the back and channeled pole on the inside

Perfect Lightweight Sheets for Sensitive Hot sleepers
Color: Cream, Size: Queen
These sheets are soft, thin, and absolutely perfect for me. I have advanced CRPS and erythromelalgia, so I deal with severe nerve burning and heat sensitivity and cannot tolerate being overheated at all. I keep our AC between 56–64 degrees constantly, and since our studio is small, it usually stays around 61–63.
These sheets have been a lifesaver for sleep. They are lightweight, breathable, and don’t trap heat, which helps me avoid extreme flare-ups and the intense burning pain I deal with. I'm bedridden so I need to be comfortable. They feel comfortable against my skin and don’t worsen my symptoms when I’m already in a lot of pain and look nice, wash nicely.
For the price, they are also a great value. I’m genuinely grateful to have found something that helps me rest more comfortably. Will be buying more for us and gifts.

Solid edger for the price!
Easy to assemble and works well for my needs edging the driveway and sidewalk! Reasonable price and seems fairly well made so far! I’ve only used it a couple of times but does the job well!

Great Yard Helper!
So easy to use and affordable! This edger is a great time saver, easy to operate, and relatively easy to adjust although you may need a pliers or screwdriver to help with the adjustment levels, but its not difficult. I would have given this 5 stars but just one thing that is a sticking point for me is I wish this had its own stand or hanger because of its odd shape, it doesn't necessarily balance upright too well. It’s long and the guide wheel in the front sticks out. So, it is always awkward to get it tidy in the garage when not in use. Now maybe this is what it's like for landscapers…I’m not a professional. Just a homeowner doing my own upkeep. With what this costs, I’ll figure it out, and is worth the money.
