If the GRS T/S parms are accurate, and you're okay w/40Hz (should be fine for music) they should do well enough. Dayton's 8" "Classic"... -
All other things being equal (which they seldom are), if you decreased the box volume by about -25%, I'd probably recommend making the port roughly +1"...Leave a comment:

Not so much from a tuning/FR point, but from a chuffing point, I'd say yes.
For my TM (in 0.09cf) I used a 1-1/4"id tube. For a pair that'd...Leave a comment:

The Lepai 2020 is a proven 2/ch amp (pretty good SQ for $25 or so).Leave a comment:

Paul's saying that instead of PAIRS for resistors R1, R2, R3, and R4 (made from 10n(ohm), 16n, 9.1n, and 25n resistors),

Looks really good for your 1st design. Box size/tuning is "reasonable", and XO SEEMs okay.

TTBOMK, the T20 (HiVi) is only offered as an 8n(ohm) tweeter.
In Paul's writeup, he says he didn't do a design (version) for the Dayton ND tweeter...Leave a comment:

Between 2010 (orig. release) and 2017, the DX25 tweeter changed from mod "09" to "59", and Paul felt a need to update the XO.

Adding your 2 sub "sections" together, I get 0.37cf (which is WinISD's "default" vented box size for that driver), and your vent should...Leave a comment:

Many (most?) designers here would run about an 8ohm resistor in series w/the tiny 0.6uF notch (tank) cap (across the woofers coil) UNLESS you had resistance...Leave a comment:

Your XO looks "okay" (for starters). Should get you into the "tweaking" range. I see about +1 to +2 dB of baffle-step, which should...Leave a comment:

Not to be a horse's patootie, but all those connections (technically) are "parallel" cnx.
The woofer pair are "in parallel",...Leave a comment:
