  • Looking at bjorno's work it looks like the stuffing will alter response below 40Hz for a leaner response.
  • I would use the dowels between the free ends of B3&B4
  • Very lightly fill the line from the throat down to at least the bottom corner below near S4/B3
  • I don't think you need to remove the drivers.
  • I'd go in through S4

Too bad the MCA2550E is NLA.
Is MCA2550E discontinued, or out of stock?

PE shows it due in on 2/9/2012.

Hi ODougbo,

More like the attached side view. Also, from bjorno Post #105: "...Stuff evenly to half-ways of L counted from the S1 area: Total Amount of Stuffing = 0.461 lb = 0.209 kg."

Okay Oliver, crystal clear now.

Sorry about the basic TH 101 questions, this is all very new and trying to catch up.

Cool Graphic!

Thank you, Doug

The PE High/Low level amp might not have the aggressive bass rolloff.

Hi Oliver,

I tested with progressive Stuffing too but kept the weight of the Stuffing as earlier = 0.461 lb = 0.209 kg:

Hi Odougbo,

"...this is all very new and trying to catch up..."

That's why we're here, just trying to learn. By the way, when building speakers of this style with stuffing it is always good practice to leave one side plate removable until at least the initial experimenting is over. Naturally, that can get you into trouble with air leaks. So you need a good seal between the dividers and the removable side panel.

Regards,

Can one use weather stripping to help seal the side that is removable, or does it cause other problems?
