Re: 2 pi's
And after mortar joints (grouting) and cap stone (limestone) it looks like this-
Try to see past the panel absorbers, I'll probably move those...
The mortar joints are still quite dark in these pics as it was still quite wet.

Re: I want to convert my basement
If your basement has all concrete walls, you will definitely want to invest in some room treatments. I would line the walls with panel absorbers. Otherwise, you'll have worst-case room modes and lots of MF and HF reflections too. The acoustics in a ba...

Re: Horns
Thanks Wayne.
They (PE) sent me a 16ohm and an 8ohm compression driver so I had to get that straightened out first.
I only attempted this build since the horns go from 300Hz to 20,000Hz. (Really 350-18,000).
I would never have attempted had I needed...

Re: Improving acoustics in living room
The "most valuable change" is the one that provides the most benefit. That wasn't meant as an impertinent reply, but rather to highlight the fact that different environments have different problems.
The most common problems indoors are rela...

Re: Damping Foam
There isn't much to acoustic wedges. You almost can't go wrong. It's not like open cell foam is tricky to make so even the inexpensive products will be made right. And it's most vulnerable to sunlight, so since it's used indoors, you can expect it to ...

Re: Custom home theater room
I've had the most consistently good results from rooms on concrete slabs with framed drywall construction. Drywall is pretty lossy and acts like panel absorbers. Rooms on hardwood floors over crawlspaces are often problematic though. Second floor room...

Re: Concrete Vs other types of wall
Would panel absorbers fully cure the dampening or would there still be at least some dampening issues? How much would it help if the ceiling wasn't concrete as well?

Re: What's your first move?
Plush furnishings can help damp reflections and help calm a live room.
If after setting everything up you still find it too live sounding, you can add panel absorbers.
Of course thick throw carpets or wall panels are easier to incorporate than ceiling ...

Re: Concrete Vs other types of wall
Concrete surfaces on all six sides (4 walls, floor and ceiling) are problematic because there is so little damping. Reflections are strong and room modes are terrible. Even if you tame the high-frequency reflections with absorbent materials, room mode...

Re: Room treatment for dummies
I don't think so.
The choir section I described was completely empty, except for a few folding metal chairs.
Even in most home settings, there is usually some type of sofa or coach for sitting, and often padding and carpet on the floors, also window ...
