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.

BTW, don't drop the bucks on the Morel units. Your tweets will do just fine. A few different values of reasonable caps on hand will let you dial it in with a little experimentation.

Hello,

Are you in Ohio? I moved to Columbus after developing the MicroWalsh series with John at Ohm Acoustics. I'd be happy to meet with you to talk about speakers, if you'd like.

B.t.w., I'd recommended the slightly larger 1000 model.

Default Updates on the Pencil?

Most likely the drivers used in the Pencil speaker are no longer being made-- do you have any suggestions?
Do you have any plans using an 8 inch driver?

Ohm uses an 8" driver in the 2000, but I prefer the 1000 model, even though it's a smaller speaker - it's particularly impressive for it's size.
