...That seems in direct contrast to my Ohm Walsh 5 speakers which don't appear to use the best of drivers, and have the signal passing through -WAY- too many components...
Appearances can be deceiving then, I guess. I'm not sure which version of W5 drivers you have, but the ones that I've seen and tested have significant advantages over the Peerless HDS woofers - particularly in terms of bass output.
I had some Walsh 5's on loan for about a year, few other speakers I've auditioned could play as cleanly, nearly that full range at in front of the stage rock-concert level volume. (I used my Onkyo TS-DX787 in "Stereo Direct" mode, playing CD music such as New World Order by Ministry and Sober by Tool with the volume set at "-0db")
I too have been fixated on the idea of "minimalist crossovers" for years now, without any scientifically tested basis - just a "gut feeling" that I want a simpler crossover. I haven't seen any testing, anywhere, that supports audible superiority of simpler crossovers (other than comparing different slopes). Some people prefer LR6, but general consensus (as much as there is one) seems to concur that LR2 is best due to superior even power response, when using drivers capable of performing well with those slopes...
I'm about to build the enclosures can someone help me with making adjustments to port tuning. The design uses a 57mm diameter port,105mm length. I have 1.5", 2.0 " and 2.5" diameter port material. Can someone recalculate the port tuning, based on what I have? My computer is a Mac so,I can't use the normal design software.
Thanks

2.5" dia. @ 5.3" long, or 2 x 1.5" dia. @ 4" long for stock tuning. What are the specs on the woof you're using?
So, 16L looks better.
Now,what dimensions for box and tuning?
You can do whatever you'd like for dims! But, if the original designer knows something that I don't (such as actual measured specs), there could be a little trouble brewing here. Let me through this woofer in a better modeler later on today...
fwater:I really don't know if the original designer knows something we both don't, like actual measured spec's. I have tried to contact Jusper about this design and so far no response. That is why I am posting here. Please, do check
another modeler and get back to me.
critofer:Just checked the design featured on Troels website for the Peerless HDSPPB830860. 8.2L, Fb= 58Hz, Port= 40mm (ID) x 70mm or 50mm (ID) x 120mm. Like I said above,I do not have any software to use for the enclosure or crossover design. If necessary I will purchase the Morel MDT-40's and use the 2.2 uF capacitor crossover Jusper used. However, the price of the MDT-40's
@ $81.00 ea. from Madisound is not what I really want to do if I don't have to
I really appreciate you guys!

Well, I've sworn off WinISD before because of inconsistent (with other simulators) results, but sometimes it's just so quick. Hornresp, which I trust, shows good results in 15 liters (-3dB @ 40Hz), but 10 liters is pretty good for this woofer, too (-3dB @ 50Hz, -10dB @ 40Hz). I say go with the stock enclosure to ease the build. Squeezing out a few extra Hz with a bigger enclosure might be worth it if yo want to shuffle the cab around a bit.
In 10 and 15 liters, this port gives both tunings.
