<h1>PMC Loudspeakers ci140sub Custom Install Speaker</h1>
<i>The PMC Loudspeakers ci140sub is the ultimate in on-wall loudspeaker design. The ci140sub is the perfect subwoofer in a Dolby Atmos mix room where space is limited, and high SPL & rich sound is needed. </i><br /><br />The PMC Loudspeakers ci140sub is complemented by the dedicated and identically sized ci140, for the apex in on-wall home theatre performance. Employing the same four bass drive units used in the ci140 and operating with the ATL, the sub reproduces additional low-frequency energy, perfect for home theatre installations and full-frequency music reproduction in high-end home audio and professional studio situations.<br /><br />The PMC Loudspeakers ci140 has a complement of four 5” LTX™ long-throw woofers, the Laminair-enhanced Advanced Transmission Line, a 2” soft-dome mid-range unit and a 27mm tweeter, it presents an audio soundstage as big as the movie you’re mixing (or just watching). Powerful bass, ultra-clear mids and exquisite highs all combine to put you right in the heart of the action, with all the detail and nuances the director imagined brought to life by this sublime speaker. For added depth and power, the identically sized ci140sub, provides high-definition low-frequency information.<br /><br />
<h3>The PMC ci series</h3>
	The ci series are ideal for playback of stereo and immersive formats, and the largest models provide the greatest headroom, bass and dynamics. All models apart from the ci140 and ci140sub may be mounted in- or on-wall, thanks to their Qikfire™ fittings, bezel-less grille and stylish cabinet sleeve.
<br /><br />
<h4>On-wall mounting</h4>

<br /><br />
<h3>ATL - Advanced Transmission Line</h3>
The source of PMC’s legendary natural, realistic sound is the Advanced Transmission Line (ATL) bass technology, professionally proven all around the world.
<br /><br />
ATL uses energy generated by the bass unit in a much more intelligent, efficient way than speaker designs based on ported or sealed boxes.<br />
<ul>
	<li>Greater detail & more natural</li>
	<li>A full, rich sound at any volume level</li>
	<li>Deeper bass from a smaller cabinet</li>
</ul>
<br />
<h3>Laminair Vent</h3>
PMC’s Laminair™ aerodynamic vent takes audio performance to the next level, by applying ATL aerodynamic principles from high-performance engineering used from F1 to Le Mans and creating an even smoother, laminar air flow at the exit from the transmission line.
<br /><br />
ATL designs involve air moving at high speeds and under pressure.Reducing turbulence and drag at the ATL vent reduces resistance, increases efficiency, eliminates air noise and provides bass with supreme timing and the widest possible dynamic range.The combination of ATL and Laminair takes audio quality to unparalleled new heights:<br /><br />
<ul>
	<li>Faster, cleaner bass and higher definition sound throughout</li>
	<li>Turbulence is eliminated, increasing the efficiency of the ATL</li>
	<li>Removes air noise — only the music remains</li>
	<li>Higher maximum output and bass with supreme timing and dynamics</li>
</ul>
