[QUOTE="Don J Davis, post: 138805, member: 248"] Re: New DIY Mid High Here is an update based on Peter's response. I changed the horn panels to match more closely to his and refined some other details. Basic volume calculations are as follows: (if my math is right) Main chamber is 59.34 Liters before deducts for drivers and HF950. After deducts would be about 47.7L. I had to guestimate the 950 since there are no published specs on its volume. No bracing has been taken into account. Horn paths: 24.83 Liters each. No bracing has been taken into account. I've included some shading to show how volume was calculated. The interior width of the cabinet is 346mm. Peter has truly managed to squeeze a lot into a small package. I'll update it further once more info is available. [/QUOTE]
