Svs sb 1000 one of the smallest 12 inch sub in the world, size comparison

Svs sb 1000 compare to gaming pc medium size (normal motherboard atx size) , a 5 inch studio monitor ( prodipe pro 5 ) and a portable bluetooth speaker( harman kardon onyx 5 ). The gap between edges and the driver of the sb 1000 in front side was about 1/4 inch or 0.6 cm which is extremely small so the woofer takes all the front panel (13inch) and all the sides of the sub are the same size (13 inch=33cm). It&slightly bigger than a z906 subwoofer but smaller than a logitech z5500 sub . I bought the sb 1000 for 400 euros in second hand a year ago with warranty until mid 2021 and a the pair of monitors 100 euros which is very cheap but nice for their price .
