What matters here is the \u003cstrong\u003ebuilt-in phono preamp\u003c\/strong\u003e, a phono input with a Phono\/Line switch and a proper earth screw terminal. A moving-magnet cartridge puts out only a few thousandths of a volt and needs RIAA equalisation before anything else can use it, which normally means a separate box or an amplifier with a PHONO socket. These do it internally, so a turntable connects straight in.\u003c\/p\u003e\n\u003cp\u003eThat makes them one of the shortest routes from an \u003ca href=\"\/collections\/turntables\"\u003eentry-level turntable\u003c\/a\u003e to sound in the room: deck, speakers, done. No receiver, no separate phono stage, no amplifier. If you are still deciding, our \u003ca href=\"\/pages\/record-player-buying-guide\"\u003erecord player buying guide\u003c\/a\u003e explains the signal chain and what each part actually does.\u003c\/p\u003e\n\u003cp\u003eFlip the switch to Line and the same input takes any line-level source, so a deck that already has its own phono stage works too.\u003c\/p\u003e\n\u003ch2\u003eHow they sound\u003c\/h2\u003e\n\u003cp\u003eA 1\" aluminium LTS tweeter sits in Klipsch's 90° x 90° square Tractrix horn, which gives the brand its characteristic directness and keeps the stereo image stable across a wide seat. The spun-copper thermoformed crystal polymer (TCP) woofer uses steeper cone angling for a smoother response through the crossover. The cabinet is MDF, bass-reflex via a rear-firing port, so leave some clearance behind them rather than pushing them flat against a wall.\u003c\/p\u003e\n\u003cp\u003eDynamic Bass EQ lifts the low end at lower volumes, where the ear is least sensitive to it. A low-profile magnetic grille lets you run them covered in black, or exposed with the copper woofer showing.\u003c\/p\u003e\n\u003ch2\u003eIn the box\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eTwo speakers (the right one is the active, powered unit)\u003c\/li\u003e\n\u003cli\u003eRemote control with 2 x AAA batteries\u003c\/li\u003e\n\u003cli\u003e4 m speaker wire with soldered tips\u003c\/li\u003e\n\u003cli\u003e2 m power cord (region specific)\u003c\/li\u003e\n\u003cli\u003e2 m USB Type A to Type B cable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe internal power supply is rated 100V to 240V, 50\/60Hz, so it runs on Indian mains without a converter.\u003c\/p\u003e\n\u003ch2\u003eWhich one is right for you?\u003c\/h2\u003e\n\u003cp\u003eChoose the R-40PM if the speakers will sit close to you, on a desk or a shelf within a couple of metres, or if the room is small. If you want more output and lower bass for a living room, compare the \u003ca href=\"\/products\/klipsch-r-50pm-powered-speakers\"\u003eR-50PM\u003c\/a\u003e, which has a bigger woofer and roughly double the power.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eCan I connect a turntable directly to the Klipsch R-40PM?\u003c\/h3\u003e\n\u003cp\u003eYes. The R-40PM has a phono input with a Phono\/Line switch and an earth screw terminal, so a moving-magnet turntable connects straight in with no separate phono stage or amplifier. If your deck already has its own phono preamp, set the switch to Line instead.\u003c\/p\u003e\n\u003ch3\u003eDo I need an amplifier or receiver with these?\u003c\/h3\u003e\n\u003cp\u003eNo. These are powered (active) monitors. The amplification is built into the right speaker, and the left speaker connects to it with the supplied wire. That is the point of the design: no receiver, no separate amp.\u003c\/p\u003e\n\u003ch3\u003eWill they work on Indian mains?\u003c\/h3\u003e\n\u003cp\u003eYes. The internal power supply is rated 100V to 240V at 50\/60Hz, so no step-down transformer is needed. The power cord supplied is region specific.\u003c\/p\u003e\n\u003ch3\u003eR-40PM or R-50PM, which should I buy?\u003c\/h3\u003e\n\u003cp\u003eThe R-40PM has a 4\" woofer, 70W total system power and reaches 60Hz. The R-50PM has a 5.25\" woofer, 120W and reaches 55Hz, with a higher 104dB maximum output. Pick the R-40PM for a desk or small room, the R-50PM for a living room or if you want more low end.\u003c\/p\u003e\n\u003ch3\u003eCan I add a subwoofer later?\u003c\/h3\u003e\n\u003cp\u003eYes.
