Dayton Audio DC160-8 6-1/2" Classic Woofer
Good Candidate with a PR? I have a 0.43 ft^3 enclosure for this speaker and the Dayton SD215-PR 8" passive radiator. Some free PR calculators indicate I need to remove mass to tune to 48Hz, what should effective PR Mms be? (75g stock) Bad idea?
This will be a good combination in that volume, but the tuning frequency will be slightly lower at about 42-43 Hz. This will not negatively affect anything however. Using the stock Mms of the PR (75g) will achieve this tune.

I flush-mounted this speaker, and want to peel off the paper/fiber/whatever ring around the outside of the speaker. Can I do this without hurting anything? The stuff surrounding my Dayton Audio 12" DVC subwoofer is already peeling off by itself.
As long as you do not detach the surround from the frame there is no problem removing the gasket.

What is the speaker displacement?
This displaces 0.0208 cubic feet, or 0.59 liters of volume.

would this be a good choice for a DIY in-wall 2.2 system (2 main spks., 2 subs.)
Yes, they will be fine. You will need a tweet and crossover, but lots of choices available there. Make sure your system includes a high-pass for the mains just to prevent excursion problems if you push it. Hope this helps.

88 SPL for 8 ohm, but only 86 Db for 4 ohm?
I'm planning to use this woofer with a Lepai 2020, and small bookshelf speakers mounted on the side of the sub enclosure. Debating between 8 and 4 ohm (4 ohm usually plays louder, right?) I see a 2 Db difference between them, with the 8 ohm at 88, and the 4 at 86. How can this be? I'd rather turn the bass volume down on the Lepai with an efficient woofer, that to use L-pads on the bookshelf speakers.
Not necessarily. A 4 ohm speaker presents a lower impedance to the amplifier (less resistance to current) allowing it to pass more power to the speaker. The primary advantage is in the use of multiple speakers. The addition of an extra speaker results in a +3db increase an sound preasure level. I don't know for sure, but the difference in vc winding between 4 & 8 ohm could account for the spl rating difference.Is it important? Yes and no. 3db is imperceptable. The typical human can't tell. Now, this is where it gets important: When choosing a speaker you have to balance your needs with the capability of the amp. The Lepai 2020 is a SMALL amp, and doesn't appear to be rated at 4 ohms. Trying to run a 4 ohm speaker on a small amp can lead to failure. The amp sees the low impedance as a black hole and tries to fill it. Not good.If you are planning to use the dc 160-8 in PARALLEL with the bookshelf speakers, you're allready in trouble. The only way that will work is with a subwoofer crossover like the260-220. The good news is you need only one. You can CAREFULLY cut the pcb in half--between the two 125mf 100v capacitors in the middle. Use one half in each sub with the sat. out feeding the bookshelf for that side. That way, you'll maintain an 8-0hm load and keep the amp happy while properly dividing freqs. and keeping your ears happy.With the 2020, if you want to push hard, consider springing for an upgraded power supply; 5 amps would really help.Hope this helps.

What is the recommended internal cubic feet for this woofer
I'm making my own ported inclosure and couldn't findThe recommended internal volume, thanks.
i came up with 0.45 cf (12.7 liters) with a 2" diameter 9" long port, with a roll off of 45 or 46 hz and a resonant frequency of 42 hz. sounds good to me! im thinking of doing the exact same thing you are doing with these woofers, lots of good reviews. hope this helps, good luck!
