I used the Monacor SPC-515/WS cable for rewiring some acoustic enclosures (indoors). The original cables had a much smaller diameter than the one I purchased. An advantage of this cable is its high copper content, it's quite flexible, and the price is okay.
Since most cables you find online, with a thickness of 1.5mm2 and a composition of 99.99% OFC copper, are over 8 lei/meter, this cable is more than enough for some floor, center, or bookshelf speakers. Honestly, you don't even need expensive cables if you're not a hardcore audiophile. I'm using it with a 5.1 Taga Harmony TAV 606 V3 system. I recommend this cable, it's of good quality and very flexible. The white rubber coating is very soft and the thickness of the cables is sufficient.
Delivery was fast, about 2 days from the moment of placing the order.
