With an impressive 2 x 95 watts RMS at 2 Ω, the little QUANTUM QS-TWO is anything but slim. On the contrary, it drives loudspeaker systems with 4, 3 or 2 Ω impedance without difficulty and remains very stable even under critical loads. With a mono bridge output of 190 watts RMS at 4 Ω, it can also elicit a lot of bass from subwoofers. Incidentally, it impresses with its high-end sound: thanks to the huge bandwidth of up to 60,000 Hz and a sensationally low distortion factor of <0.007% (THD + N @ 5W), the QS-TWO is way ahead.

ESX masters the construction of Class D power amplifiers so well that the QS-TWO can come up with a sensational efficiency of up to 90% and EMC interference-free. The modern technology saves electricity, relieves the vehicle's electrical system and protects the high-quality components from overheating. Thanks to the high degree of efficiency, no thick power cables need to be pulled. If you want it to be very easy, you can use the QS-TWO-ISO, which can be supplied via a pre-assembled ISO cable harness, e.g. can be connected behind the car radio.

Definitely not worth the money you pay.
Size: 14 Ounce (Pack of 1), Set name: Standard
The dogs love them and they are great treats. The problem is for almost $20 a bag. You only get a fourth of the bag hole sweet potato strips. The rest of it is just the scraps from the skin. These get stuck in my dog’s gums and then their teeth and they’re hard to digest. I stopped buying them and went to another brand, unfortunately. I thought maybe it’s a fluke and the back got shook up, but I’ve ordered at least eight bags.

First shipment was quality
Size: 8 Ounce (Pack of 1), Set name: Standard
Initial delivery was impressive. No odor no additives and longer pieces. Second bag was full of short, burned pieces. Expense would be worth it, if quality control existed.
