GIK Vicoustic and others

Use the long axis ( placement on room width ). 

Find out what the radiation pattern is for the Sonus Faber Ellipsa and you will have some idea where to start.

No Loudspeaker should overload ( be unusable ) for a reasonably sized room.

Work out how to treat for low end response and the rest will be less of an issue.

Once low frequency is addressed moving out of close field is possible.

I’d insulate because it’s the basement, but no need for double drywall. Another place to put insulation is in the ceiling, it will definitely cut down on the noise complainants from upstairs 😁

All the best.

I ordered from GIK and was not pleased.  It took two months for the products to arrive. And when they did, they were poorly packaged and all four pieces were damaged. Took close to another 2 months to get replacement pieces for the damaged pieces. I could have overlooked the delays if the products had arrived in good condition, but based on my first experience with the delays and damage, I am unlikely to go back to them for any future purchases.

@ bjp9738 My friend had a similar experience, long wait for poorly packaged damaged panels. They did not replace the entire panel, just the front plates, and he had to fix them himself. Sounds like Vicoustic is more professional and higher quality. 

I had the same issue with GIK. They took over 3 months and when the panels arrived, one of the front plates was broken. They sent me a new one pretty quickly. The rest of the panels were pretty good though. However, the second shipment had panels with with very visible creases all over, corners not cut properly, and an overall looser fit. The fit and finish was not indicative of the prices they charge. They told me it would be another 3 months to send the replacements. I was tired of waiting so just kept the panels. It seems GIK is now hit and miss depending on who works on your panels. I won't be ordering from them anymore.
