The tweeters use edge-driven textile domes that deliver clear highs without harshness even at higher volumes, and when paired with larger Reference component systems they offer a tweeter output level control to fine-tune system balance. For anyone upgrading factory speakers who values tonal accuracy over artificial brightness, these tweeters are a compelling, well-engineered option.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAudiophile-grade tweeter:\u003c\/strong\u003e Edge-driven textile design provides smooth, detailed highs that resist listener fatigue during long listening sessions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable tweeter level:\u003c\/strong\u003e Larger Reference component systems include level control to optimize high-frequency balance for installation location or personal preference.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlus One cone technology:\u003c\/strong\u003e Harman's Plus One multi-element cones increase cone surface area for higher sensitivity and fuller low-frequency output in matched systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact design:\u003c\/strong\u003e Small tweeter size and form allow installation in tight factory locations without extensive panel modification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem-oriented engineering:\u003c\/strong\u003e Designed to integrate with Infinity Reference speakers for linear response and cohesive imaging across the soundstage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThese tweeters are best for car audio enthusiasts upgrading from factory-installed speakers who care about smooth, accurate treble and natural tonal balance.
