Peerless SDS-160F25PR01-08 6-1/2" Paper Cone Woofer Speaker
What is the "horizontal" overall width of this speaker compared to the "vertical" width, since the sides are sliced off?
The frame of this woofer measures 6.45" across the flats and 7.165" across the round edges.

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.

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.

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.

usable for vented? recommended volume?
It looks good in a vented enclosure, usable from about .6 to 1.5 cuft tuned to 35-40hz.
