Re: Back loaded corner horn
Corner loading is pretty simple really. A corner confines the radiation pattern to eighth-space and in so doing provides 9dB DI. There are other issues to consider, such as crossover points and room modes, but those are specific to the design and the ro...

Re: How many subs are enough?
Outdoors, I would prefer the subs packed close together, ideally within 1/4λ from each other and from the mains. The idea is to create a single sound source so there is no cancellation interference between sound sources. In this case, a single sub would...

Re: Treatment for a cancellation notch - Multiple subs
Yes, we have discussed this before and I will admit to have a bit of reticence in adding more speakers to my rather small room for reasons of visual impact, more wires, which is why I'm still pursuing the passive route at the moment.....But I do have that...

Re: Treatment for a cancellation notch - Multiple subs
The best thing to do is to add subs. I think you and I discussed this before, but just to be sure I'll hit the high points. The idea of adding subs isn't just to augment the low end but also to smooth room modes. Having just two subs added to the two b...

How about multiple smaller subs?
I would opt for more subs, not larger. That will allow you to smooth room modes. My suggestion would be to use four smaller subs and position them where CARA shows will give you the smoothest bass throughout the room. An example would be four LAB12 woo...

Room modes
Sounds like a well-built structure, but it also sounds very rigid. I'll bet your room modes are very well defined. If that's the case then any speaker with some bass will energize the modes and they'll stand out.Best thing to smooth room modes is multip...

Re: LSAF 2008 - Show Coverage, Seminar Recordings, Slideshows and Handouts
Don't leave out Skip Pack and Bob Brines. They generally have very good sounding systems. I regret that I didn't get a chance to stop by and listen. Too much to do!About Duke's speakers, I was able to listen briefly and what I heard sounded very good. ...
