I finally tried out the 24s. I have done absolutely nothing to them except wipe down the exterior. They both measured 6.6 ohms across the terminals, so I decided to cross my fingers and give them a gentle go in my new listening closet. The Sansuis in there just didn't have any bass, so I looked at the Jensens and said to self, "These have to have some bass."
Well, they sure did. But the surprising part is that even on the floor, they have a great vertical soundstage. Very unexpected.
