For those who have followed the subwoofer wars, about 15 months ago, Hsu Research announced their new VTF-3 HO. It was touted as being competitive with any 12 inch subwoofer, and was promised to have a "turbo" option which would extend the bass without the usual loss in SPL which port blockers caused.
After a few delays, we received a pair of VTF-3 HO's last week, complete with Turbo.
Last June, we purchased a couple SVS PB12-Ultras.
Now that the Hsu's have had a few days, it is time for a blind shootout.
For the system, they will be paired with the Emotiva DMC-1/MPS-1, a modded Denon 2900, and ACI's Sapphire XL's.
We can do some pretty quick swap outs ... and tonight we will start the listening impressions "blind". Both subwoofers are level matched, and have comparable in room response curves.
Right now, Steely Dan's "Two Against Nature" is playing on subwoofer "A". More later ...
