| "Even at the lowest fundamental frequencies the IDMAX effortlessly reproduces the music faithfully with transient detail and tonal accuracy that is the result of very low harmonic distortion. Combine the musical abilities of the IDMAX with its ability to produce truly violent SPL levels and this subwoofers popularity is quickly understood. Several mechanical design difficulties had to be conquered to attain the performance goals established for the IDMAX subwoofers. Keep moving mass as light as possible to MAX-imize sensitivity. Do not give up cone area to increase excursion, to MAX-imize volume of displacement MAX-imize thermal power handling to reduce power compression and MAX-imize output at high power levels. Motor and Suspension design with very long linear excursion for low distortion very high output operation. The IDMAX conquers or MAX-imizes all of the above difficulties. The IDMAX12 has 90.5% more linear displacement than an IDQ12 V.2 while it’s moving mass is over 20 grams lower (IDMAX12 = 141 grams versus IDQ12 V.2 = 165 grams). This is a real feat of engineering that truly yields MAX-imum output potential. With the patent pending RaDiaToR© System we MAX-mized thermal power handling and reduced thermal power compression. The RaDiaToR© effectively increases the subwoofers ability to remove destructive heat from the voice coil increasing thermal power handling while virtually eliminating thermal related failures Massive excursion engineered in the IDMAX boasts a SPL producing 24.9 mm one-way linear excursion (Xmax) with a 3.70"" peak-to-peak (Xsus) suspension excursion. Larger piston area results from the Unisurround V1.1 allowing the IDMAX to achieve very long excursion without reducing cone area. Since very little of the surround of a long excursion subwoofer actually contributes to the displacement of the subwoofer their reduced cone diameter results in lower displacement requiring a substantial increase in linear Xmax just to equal the displacement of the IDMAX. To MAX-imize performance hundreds of hours were spent utilizing the latest computer aided engineering methods and Models built to design the parts necessary: cone body, suspension, voice coil, motor assembly, basket and surround. Rather than choosing to utilize the same parts common to most long excursion subwoofers, (and the limited performance that they are capable of) Image Dynamics has invested in tooling all of the proprietary parts necessary. You won’t find this performance or these parts in any other subwoofer. The IDMAX performance is truly unique of long excursion subwoofers as they achieve high SPL even from small amplifiers. The reason for this is the IDMAX is like a Formula 1 Race car where advanced engineering, materials, and assembly techniques are utilized to maximize performance. From the Structural cored composite cone body to the high-tech voice-coil winding methods every part of the IDMAX was engineered to be extremely strong, yet super light in weight. The low moving mass of the IDMAX requires less suspension stiffness to balance the mass to the compliance for proper cone control at high power levels. Lower moving mass in a speaker results in higher efficiency because more power is being used to create sound rather than overcome weight. Softer high compliance suspensions also result in higher efficiency because less of your precious amplifier power is being used to overcome the stiffness of the suspension. So even with moderate power levels as low as 100 watts the IDMAX subwoofers will produce high output levels and with very high power levels up to 1800 watts they will produce truly explosive and violent levels of clean undistorted sub-bass.
