In the Thread: Thoughts on midbass horn approach
Post Subject: More explanationPosted by noviygera on: 8/8/2018
Romy, thank you for your thoughts. First off, my further thought on the system and specifically the implementation of the high freq section: Yes, the time alignment would be a challenge but possible. This is the main compromise, in my view but the least objectionable compromise to use DSP delay on the high freq section. I'm not a fan of DSP and I say this because I know first hand of the drawbacks of inevitable compromise of sound quality. But out of all compromises, this one I decided to accept, as the least objectionable use of DSP, solely on the high freq section, and in the low bass section (subwoofer). To me, it is best to keep DSP away from midbass and midrange horn, and this configuration would make this possible, as the essential part of sound range would be without DSP.
Now about the midbass horn. I do not know the driver, throat, and profile. All I can say about this channel is my general idea, which is it can be 14 foot long folded horn and the size of the midbass box 32"x45"x40". This is the volume of space that will be "available". I do not plan to design it myself but have an expert do the design, recommend the driver, within those space constraints. Since you say any midbass horn will shoot above 120hz, the variable that is left is how low will it play. I'm not setting a goal freq of how low. This will be dictated by the volume and what the designer will propose as a good lower knee for the driver/horn combination based on space constraints and his design.
I do not have an expert designer but would be very thankful to anyone who can recommend someone competent.
So let's say this expert will tell me he can design something within those space constrains with such and such driver and it will be useable down to 50hz in the location of my room. I will be conservative in my expectations but if I get only 60hz, that is no issue at all.The low bass section will be on DSP and will be adjusted to meet the midbass.What do you think of this approach?Rerurn to Romy the Cat's Site
