Woofer size for uniform directivity loudspeakers
Personally, I wouldn't go to a 10" driver. In my experience, there is too much midrange off-axis, and it makes a bad directivity match. Also, they usually don't have high enough sensitivity for my tastes unless tuned as a dedicated midrange. For ...

Baffle Step
In my opinion, baffle step compensation filters can be useful, but only for a fairly limited number of loudspeaker types. I think they are way overused in the DIY community. BSC filters are best suited for little mini-monitor speakers with small baffle...

Sound system installation and room treatments
Be careful when choosing contractors to build a sound room and/or treat an existing room and setup. Experience and ability varies a great deal, but of course, they'll all represent themselves as experts.
I would strongly suggest that you take time an...

Re: Advantages of getting a 3D speaker
If what you want is loudspeakers that create a very good illusion that sound sources seem to be coming from places matching what you're seeing on the screen, then I would suggest studying the topics of constant directivity, uniform reverberent field, Haa...

Re: 7pi Plans
Yes, that's true. I noticed that I mislabeled that a while back, meant to change it and forgot. It's been labeled like that for a while.
About woofer sensitivity, I'd pad the midhorn and tweeter to match. You might build it as-is and measure to fin...

Cornerhorn Ruminations
Nice looking midhorns! Congratulations!
We will have the midhorn flat pack kits back on the shopping cart in about a month or six weeks (finally!) I met with the cabinetmaker on Sunday and we discussed it at length.
You can keep stuff out of the ...

Re: 4 Pi and 7 Pi bass response- More similar or different?
SET is an abbreviation for single ended triode. FET is field effect transistor. I was trying to describe the difference as being like a high quality Class A tube amp compared with a high quality Class A solid state amp.
Both are detailed, both s...

Multisub explained
I'd probably generally suggest crossing subs below 100Hz but in smaller rooms, sometimes a little higher crossover is merited for specific setups. This is part of the multisub approach, which distributes low frequency sound sources. By "low freque...

Re: On axis measurements in nearfield listening
I think not enough people building line arrays depend on measurements like they should. Measurements are extremely important with arrays if you want the best sound.

Re: On axis measurements in nearfield listening
What I'm saying is that a loudspeaker produces sound eminating all directions from it, not just straight forward. This goes without saying, I suppose, and you're aware of it or you wouldn't have brought it up here. What I'm also saying is that I believ...
