I've had the Hornshoppe Horns and they do not need to be placed in the corner to get the best sound. They were great but I upgraded to the MG944s to get more bass and I never was satisfied. Something was lost in the trade: air and coherence, which are some of the dominant traits of single drivers when done well.
I've since graduated to Tonian Labs TL0-D1s which expand on the single driver theme with a super tweeter and are better executed (I get very convincing bass, tone and texture) The Tektons physically resemble the Tonians in that regard and from what I've read adequately address the lower mids and bass.
In all honesty, I think the Hornshoppe Horns or the Decware MG944s will be a step sideways and may not be your cup of tea if you really like the sound of the Tektons.
All the best,
