Copenhagen Loudspeaker Company is now shipping the\u00a0CLC65 loudspeakers for \u20ac9,490 per pair<\/strong>, with the company\u2019s U.S. storefront currently listing them at\u00a0$10,853 per pair<\/a>. Worldwide shipping, duties and taxes are included, along with a 30 day home trial. That is not inexpensive, but at least the price should not develop several mysterious growths while crossing the Atlantic.<\/p>\n\n\n\n

The CLC65 made its U.S. debut at AXPONA 2026<\/a>, where pricing had not yet been announced. The Danish company describes it as the first commercially available three way loudspeaker built exclusively with Purifi drivers. Plenty of manufacturers use Purifi woofers, but CLC has handed the tweeter, midrange, woofer and both passive radiators to the same Danish driver specialist.<\/p>\n\n\n\n

Purifi Everywhere<\/h2>\n\n\n\n

The front baffle contains a\u00a033mm Purifi PTT1.3 tweeter\u00a0mounted within a substantial 147mm waveguide, a\u00a06.5-inch PTT6.5M midrange driver\u00a0and a\u00a010-inch PTT10.0X long stroke woofer.<\/p>\n\n\n\n

Around the back are two more 10-inch Purifi PTT10.0PR passive radiators. Those replace a conventional bass reflex port and are intended to extend low frequency output without introducing port noise. CLC rates the system from\u00a028Hz to 20kHz<\/strong>, which would give the CLC65 genuine full range aspirations in most rooms.<\/p>\n\n\n\n

The crossover is fundamentally a second order design with transition points at 250Hz and 2kHz<\/strong>. CLC uses air core inductors, ClarityCap ESA capacitors, copper foil bypass capacitors and a Jantzen C core inductor in the bass section. WBT Nextgen copper binding posts support banana plugs, spades, bare cable, biwiring and biamping.<\/p>\n\n\n\n

That collection of components will appeal to listeners who spend their evenings studying crossover photographs. The rest of us are more interested in whether the drivers behave like one loudspeaker rather than five highly accomplished engineers talking over one another.<\/p>\n\n\n

This Is Not a Bookshelf Speaker<\/h2>\n\n\n\n

The CLC65 measures 28.3 inches tall, 13 inches wide and 16 inches deep, with each cabinet weighing 88 pounds. Calling it a bookshelf loudspeaker would be technically convenient and structurally reckless.<\/p>\n\n\n\n

Dedicated CLC65 stands cost \u20ac990 per pair<\/strong>, while the curved magnetic grilles add another \u20ac290<\/strong>. Without the grilles, the large exposed drivers give the speaker a distinctly retro studio monitor appearance. Add them and the design becomes more domestically acceptable, assuming nobody notices the pair of 88 pound Danish refrigerators sitting beside the equipment rack.<\/p>\n\n\n\n

Satin black and satin white versions are available. The satin walnut finish is currently sold out, with additional inventory expected in December and a \u20ac500 preorder discount being offered for that version.<\/p>\n\n\n\n

Your Amplifier Needs Some Muscle<\/h2>\n\n\n\n

Sensitivity is rated at\u00a086dB<\/strong>, with a nominal impedance of\u00a04 ohms<\/strong>\u00a0and a minimum of 3 ohms<\/strong>. CLC recommends at least 100 watts of amplification.<\/p>\n\n\n\n

That does not automatically rule out every tube amplifier, but this is clearly a loudspeaker designed for an amplifier with meaningful current delivery and control. A lightweight 25 watt integrated amplifier purchased because the faceplate looked charming on Instagram is probably not getting invited to this particular sm\u00f8rrebr\u00f8d party.<\/p>\n\n\n\n

The large woofer and two passive radiators also suggest that room placement will require some experimentation. CLC says the passive radiator design reduces sensitivity to placement compared with a traditional port, but two rear firing 10 inch surfaces still need room to interact with the wall behind them. Physics may not write marketing copy, but it remains annoyingly involved in the final result.<\/p>\n\n\n\n
