I believe they are 125 rms nominal and I have no clue whether jl suggested 250 as a maximum rms or maximum peak.
I was under the assumption winisd modeled using maximum power?
The 600 watts was a bench test in a video I posted in the thread awhile back. Perhaps 600 was optimistic but they certianly seemed intent on attempted destruction of the driver with far more wattage than it should ever receive.
Cool, now i can stop tinkering with 6th order bandpass in a small box. 4th order does seem tempting due to natural low pass and hi pass, limited delay and distortion, and a few db gain at 30 hz compared to sealed but i can only imagine the difficulty of sealing the baffle inside the tube.
I haven't had much interest in the build lately due to cost to performance ratio but i've figured out a way to add a little extra volume to the tube without using a bigger tube (which I can't seem to find around here).
I have a bunch of thick walled pvc lying around and I figure it would be neat to create a stand out of it opening into the bottom plate of the tube and a second bottom plate sealing of the pvc piping.
I was thinking of using 4 3" diameter by 4" length pvc pipes to make up the 4 legged stand.
2 questions come to mind:
1) What effect if any will the enclosure change from the fiber tube to the pipes have on effective volume due to possible compression?
Just a quick update, I lost interest in the build/wasn't able to make use of the right tools for the job.
On the other hand I learned more than I would have imagined from the planning process and I just wanted to thank everyone who helped me out with this project.
I am currently planning a small set of pvc full range's, possibly with a multi directional design. Hopefully I will have better luck starting with smaller speakers and it looks like it will be a lifelong hobby for me.
