pretty cool.
these are almost 6' tall (1800 mm) giving them a very low tuning. with the driver Fs of 90 hz, what is the lower limit in these enclosures?
Loving the curvy Chang. They look smaller than I imagined. Which drivers are they? How do they sound?
Drivers are Fostex FE207E. I dont have plenty of experience with different FR speakers (as matter of fact- this is my second project), but I love the sound they produce- very clear and detailed, no disortion which could disrupt the enjoyment of music.
207Es, then your TV is much bigger than I thought.
My next project is something similar. I love the BiBs but I want to try some rear loaded horns with double openings...they look great.

Beautiful job with these, must make for an amazing combination!!

The lower limit in them is about 30Hz.
Derwent cabinets with CSS EL70 drivers
Here are a few pics of my Derwent speakers with CSS EL70 drivers. The design is from the 'Lake District Series' from the frugal-phile.com. Thanks to Dave from Planet10-hifi for his help with all my questions I kept emailing him with.
They are made from 18mm maple ply and stuck with polyurethane glue.
I haven't run them in yet, but after half an hour of listening, they sound as good as Dave said they would. I can't believe the low end these speakers can produce in these cabinets. I am running them from my LM4780 Gainclone 🙂

Well done!
You should have a very satisfying combination of driver and enclosure(s)
Having heard those drivers, I agree they're not bass shy!

Lovely! I was very interested in that design. Glad to hear someone had a good experience building then.

Kind of a sucky picture, but my camera is packed away or lost or something.
Uses two Silver Flute W17 8ohm woofers and an FE83en. 4 component cross over. Sealed cab. Meant for home theatre use as a centre channel speaker. Does what it's supposed to do, provide good horizontal coverage without reflection aberations.
Attached measurements are an outdoor smoothed (red) and an outdoor gated combined with a nearfield (green). Impedance also attached. I left the hiccup at 2khz alone. It sounds fine. The peakiness around 150hz is more audible actually, at least in my room. Easily corrected by receiver eq. That peak is my doing in the cross over. Was necessary to get the woofer stop band low enough to not screw up the midrange.
Planet10 outfitted the drivers with his handywork. They look great. I really owe this one a better picture. The cab is walnut stained black. The chamfer trim is birsdseye maple with red transtint. Matches the enable dots 🙂
