On Wavtech's figures (Fs 26 Hz, Qts 0.46, Vas 42 liters) that is Qtc 0.851 with system resonance at 48.1 Hz and half power at 41.3 Hz: firm and punchy, a little above maximally flat.\u003c\/p\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"po-section\"\u003e\n\u003ch2\u003eTwo Fully Separate Chambers\u003c\/h2\u003e\n\u003cp\u003eA bonded 3\/4 inch MDF divider runs front to back at mid-width, so each thinPRO 12 has its own 0.61 cubic feet and neither cone loads the other.

Chamber A's leads pass to it through a small sealed hole in the divider, so the two chambers stay separate. The thinPRO12-4 is rated 750 watts RMS; aim for roughly 525 to 750 watts per driver at the impedance you wire. The cutouts are 11.125 inches under the 13.06 inch frame. Wavtech publishes no bolt circle, so the woofers are mounted with a threaded insert kit and stainless machine screws, marked from the driver.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"po-section\"\u003e\n\u003ch2\u003eBuilt in Tennessee, Backed by Audio Intensity\u003c\/h2\u003e\n\u003cp\u003eCut and assembled in Tullahoma, Tennessee on our own CNC equipment from Langboard Elite MDF.
