Hello All,
I have a medium chamber scoop loaded with Eighteen Sound LW1400s. The issue is boxes play deep and full although, they do not have a lot of pressure or hit you in the chest hard. Would anyone be able to lend some knowledge as to what is being done wrong whether design or speaker? |

Yes.... its a sub cab not a bass cab.
Your scoop plays 80hz and dowm. Kick is about 70-200hz. You want it to THUMP, then build a short horn that plays 70-200hz. Job done!! Edited by mini-mad - 12 April 2017 at 4:43am |

If it sounds like a gorilla is trying to escape, turn it down.

Try to reduce throat/chamber size, could be too big for T/S of the driver.

Support the scoop technology, larger mouth plays louder!

Reducing the chamber size would be the reducing the airspace between the front baffle and the baffle behind the speaker? Would you suggest adding another baffle behind the front? It would not be possible for me to add to the rear baffle as the speaker needs the depth to fit. I could also add wadding?

Unfortunately, I do not have the exact dimension of how much space is between the magnet and the second baffle. I do not think there is enough space to add to the baffle on the back side. I would have to add it on the inner side of the front baffle. The inner dimensions of the chamber is roughly 24" by 24" by 8.9" if that helps. Now when you say throat issue can that be fixed?

the lw1400 is a nice driver but not my first choice even for a cheaper end of the range driver.

We all know that the PD, Void, and Turbomax are the most respected and best. With that said those are diffidukt to obtain here in America. What would be you choice for a speaker in this class?

I do not have the full design either. The cabinet designer / building wasn't a nice guy hence my issue. You are correct. This design is similar to a super scoop without the dogleg, and braces behind the second and third baffle, as well as no brace in the mouth. I do have the 45 degree braces on the rear panel and behind the second baffle. Dub would you happen to have any pictures of the modifications you have done to the first baffle?
