which is the difference between the HOG SCOOP and the BASIC BASS SCOOP which is better?

I think MDF is denser and sounds better, but there are concerns about joints cracking under the weight of larger MDF boxes. Also, MDF is extremely moisture sensitive. If you built them for an install MDF would be fine. If you are carrying them around, I would recommend birch.

Can you use medium density fibre board for this box...I read somewhere that its better than ply...

That is just the area of the throat at specific points in the horn path. If you just use the measurements on the plan, you should not go wrong, unless you are trying to modify the design, and then you will have a fair bit of math to do. I would say just stick to the plan.

Yeah I know it's only calculated SPL and thanks for all the help! :)

it would probably come close if you put in all the numbers right. Horn Resp does not take into account losses from panel vibration so it would probably lose a dB or two there, but the driver would probably shred rather quickly.

Thank for quick response, but I'm just interested whether this design could actually achieve such SPL levels at these frequencies?

The red means it is exceeding xmax. Reduce the power in max spl until the problem in the middle goes away. Most of the time the max spl sim shows over excursion below cutoff so that is where I set my HPF, but the middle parts I try to eliminate. That will reduce the SPL of course. My Faital Pros in 1850s start having over excursion over 300 watts even though the speakers are rated for 1000 watts RMS.

I did the simulation in Hornresp with the numbers that bee provided and I get weird results for maximum SPL.
Could it possibly go that loud between 30-50Hz?

I'm new to hornresp so any help would be appreciated.
Thanks!

Hey guys, Do you think this would work with PD 186 or RCF LF18G401?
Thanks!
