In the Thread: Andrew's new 4-way horn using Stereolabs stone horns and DIY bass

Post Subject: It’s getting more warmer…Posted by Romy the Cat on: 6/17/2012

Ok, Andrew, this is allergy something. I would highly advise you in future before you post any discrete updates, questions, and ideas about what you to inform about the holistic objective of your project, sort of a view from 50.000 feet. That what I meant when I asked “what you do?”

About your project. I would encourage you to look for different location for your playback. The 6 feet is not the width where you will be able to host your inhalation of this topology as it will be underperform. Sure we all restricted by space but if you can find different location in your room them you might want to consider it.

So, the midbass rectangular horns are 100 to 500Hz. The lower MF horn from 500 to 5000 and the small horn cover from 5000 and up – let call it HF channel. The idea looks OK but the positioning of it very bad. If you have MF run to 5K and HF start in 5K then you shall not introduce any horizontal offset as it such high frequency you’ll have a lot of imaging smearing. I would very much advise to use the MF and HF horns in strictly vertical configuration. It might be a bit tricky in your case. You can drop you MF horn all the way down to upperbass and put HF above or you can locate the HF under the MF. In your configuration both will work but it would require some sensibility to do it in order to maintain the center image in right spot. I need more information to estimate HOW it might be done. The rate of the horns or the diameter of the mouths, the type of the drivers, the listening distance, the type of the crossovers, the high of midbass horn, the music you will be playing, the proximity to the back wall, the space behind your listening chair and etc…

Also, I would like to know what make you to propose to use the 500 to 5000 configuration but not any other configuration.
