There is no port, so the bass is tight and predictable rather than boomy and room dependent, and KLH says the cabinet can sit as close as six inches from a wall. It slots between the Model Three and the Model Five, sharing the Model Five's midrange and tweeter with the Model Three's woofer. Sold as a pair.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eWhy You'll Love It\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eSealed bass behaves in real rooms.\u003c\/b\u003e Acoustic suspension rolls off gently instead of falling off a cliff below the port tuning, which is why these stay clean close to a wall where a ported speaker would boom.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eA tone control built into the speaker.\u003c\/b\u003e The three position Acoustic Balance Control on the rear panel trims everything above 400Hz by 1.5dB or 3dB, so a bright room can be fixed at the speaker rather than in the amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eReal veneer and a proper grille.\u003c\/b\u003e Three quarter inch and one inch MDF wrapped in real wood veneer, with a magnetic knit grille in a period fabric matched to each finish.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eUnder the Hood\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eThree way acoustic suspension design with an 8 inch pulp paper woofer on a 1.5 inch flat wire voice coil, a 4 inch pulp paper midrange, both on reverse roll rubber surrounds, and a 1 inch aluminium dome tweeter.\u003c\/li\u003e\n\u003cli\u003eSecond order electro-acoustic crossover at 380Hz and 2,500Hz, with frequency response of 46Hz to 20kHz ±3dB and low frequency extension to 35Hz at -10dB.\u003c\/li\u003e\n\u003cli\u003eNominal 6Ω load dropping to 3.5Ω at 120Hz, in-room sensitivity of 88dB at 2.83V and one metre, handling 150W continuous and 600W peak.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch3\u003eCHT Insider Verdict\u003c\/h3\u003e\n\u003cp\u003eSealed floorstanders are rare now and this is a good demonstration of why they should not be. The bass goes lower than the numbers suggest because the roll off is gradual, and the wide baffle gives it a big, unfussy soundstage that suits a lounge rather than a nearfield triangle. Two practical notes. It dips to 3.5Ω, so give it an amplifier that is comfortable below four ohms rather than the cheapest thing with the right power rating. And there is a single pair of binding posts, so bi-wiring is not an option.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePro Tip:\u003c\/b\u003e Leave the Acoustic Balance Control on MID to start, which is where KLH ships it, and only move to LO if the room is hard surfaced with glass and tiles. Moving it to HI is for heavily furnished rooms with rugs, curtains and soft furniture. It is a genuinely useful control and most people never touch it.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\u003ctd
