Are any of you guys using this Hsu driver in DIY designs? I have a TN1220 that I believe uses the older 1201 driver. Has their been any significant improvements or changes to the drivers parameters in the new 1202. Also, is the ASW1202 the same driver used in the TN1220 and VTF-3. I know it states it's used in the automotive version which uses a small 1.5 ft^3 sealed enclosure. I am thinking I may be able to fit 1 or 2 sonotubes under an adjacent stairwell and vent the front of the woofers into the room. I'd rather not have big subs dominating this room. I'm guessing the space used as an IB will not work well as I'm sure the stairs and a closet door will leak like h*ll. The other candidate would be the Adire Tempest but I have no experience with it. I already know I like the Hsu for movies and it integrates well for music.
