Peerless SDS-160F25PR01-08 6-1/2" Paper Cone Woofer Speaker
usable for vented? recommended volume?
I entered the specs in my bassbox program and suggested a vented enclosure with flat response. It says to put it in 1.665 ft3. Use a 2'' round port tube that is 3'' long and it will have a f3 of 47.39 Hz. It calls for minimal dampening material. That's quite a large box for a 6.5'' speaker, which is probably why PE suggests sealed. My program suggests .442 ft3 sealed for a flat response with a f3 of 74.3 Hz with heavy dampening. You could have almost 4 of them sealed for the same size that one vented would take up. I hope this helps.

the details say a 20000 upper limit, what is the real number??
PRODUCT SPECIFICATIONSPower Handling (RMS) 60 WattsPower Handling (max) 120 WattsImpedance 8 ohmsFrequency Response 35 to 20,000 HzSensitivity 87 dB 2.83V/1mVoice Coil Diameter 1"
If you look at the frequency response in the specification PDF it starts to rolloff above 5 kHz on axis. However I would go no higher then 2.5 – 3 kHz with it as it starts to beam around that point and you want to cross below the cone breakup at 4.5k.

What size enclosure for 2 of these? vented or ported. If ported what size port.
A sealed box volume would be .7 cubic feet for both woofers, this will provide an F3 of 80 Hz. Vented is quite a bit larger at 3.2 cubic feet with a 3" diameter port that is 2.5" long. This provides a tuning frequency of 33 Hz.

I am going to build a 3 way floorstanding speaker with double Dayton Classic 8" woofer as bass drivers, and a planar tweeter. Is it a good choice as a mid range driver for the frequencies around 800hz-8khz. Is it covering 35hz - 20khz as written?
The stated frequency response is a bit ambitious and based on the response graphs in the spec sheet, it is not accurate. I will have this updated online. The highest I would cross this driver is about 2.5kHz.
