## Description

qtx Subwoofer Filter for Hi-Fi & PA Loudspeaker Systems 600W : desertcart.co.uk: Electronics & Photo

Review: cheap way to fix or create a subwoofer - used in conjunction with a pioneer S-SLW500 passive subwoofer, a box made by Sourcingmap (158mm x 90mm x 60mm Waterproof Plastic Enclosure Case DIY Junction Box), a gluegun, some copper cable and 8 spade terminals. Note : This subwoofer is stupidly cheap at Richer sounds (£5) because it's a very poor design (it's frequencies cut of is around 1.2KHz???) I trialed this on a normal speaker first and the drop in high frequencies was as one would expect/hope. This filter adds around 0.6 Ohms of imedence which is no big surprise, the main thing is, it corrects the subwoofers bigest design flaw So for about £40 all told I now have a pair of awesome subwoofers correcting the shortcomings of a baseless set of bookshelf speakers (wired to a second channel on the amp). Happy days!
Review: Works like a charm - If your getting full audio through your subwoofer and not bass only this is what you need.
