New Tekton Pendragons On The Way

I have 12X12 cathedral ceiling sunroom (on second level) and 12X12 office directly below at foundation level.

I've used diagonal setup in the office from time to time with good results. At foundation level, sound energy transferred to the floor is a non issue with both rooms there so nothing special needed below any speakers I use there.

On teh second level, with suspended plywood floors typical with newer construction, the floor transmits a lot of energy in both rooms there and isolation from the floor is key.

Can't use diagonal placement practically in teh sunroom, but the Isoacoustics stands with just a slight tilt up in a more conventional speaker setup otherwise does teh trick to a tee. Spiking conventional taller heavy stands to the floor on that level does not work nearly as well. In teh small room teh low placement with slight upward tilt and the isolation capabilities of the Isoacoustics stands in particular are the key. In my other second level larger room, I have the bottom ported OHM Walsh speakers there on Auralex subdude platforms for similar isolation.

I find with the upper level floors, you have to totally isolate the speakers from teh floor for best results in regards to detail soundstage and imaging. The devil is in teh details of the stands/solution used and how effective they are at isolating from as opposed to coupling with the loosy goosey floor.

In a small room in general, low placement with upward tilt essentially tricks teh speakers into thinking the room is larger and help with soundstage and imaging specifically, similar to corner placement.

Could effective isolation from the floors still be an issue in your case with teh Tektons? if so, might be worth addressing before giving up.

You should have kept the B word to yourself. If the moderators catch you pulling a stunt like that, you'll be ex-communicated for life.

I am a 3-D sound fanatic as well. But it's the SOTA mbl demo I heard a few years ago in a very well done custom showroom that drives me there. That and what I hear at live performances. I will never have any rooms like those to work with most likely, but have managed to do pretty well with a somewhat reasonable budget in the rooms I have, some more so than others. In all cases you have to take the room and acoustics into account and go from there. Each room is at least a little different, some way more so than others.

I have some vibrapods I can put under the M-lores to decouple them from the plinths. I'll give it a try. Although, the other speakers used in the same position have no problem being spiked to the floor.

lol. But I thoroughly enjoyed my time with them. They could really rock the house back when that was a priority for me.

Call me crazy, but these days I tend to believe that with the right setup, a lot of way more modest speakers can sound like mbl or Magico. If done well. I'm finding isolating speakers from interacting with floor is a must, however one gets to that. One way is build quality of speakers and stands but there are other ways as well. Concrete foundations and isolating speaker stands and platforms another.
