Anyone use the cheap Pioneer 8" Coaxial? Questions
Has anyone used the PIONEER B20EC82-51FX-Q Coaxial Ceiling speaker from parts express?
----------------------------------------------------------------------------------
Paper cone with poly foam surround. 2-1/2" tweeter. Full range coaxial offers great fidelity and sound. Perfect for P.A. and ceiling type applications. * Power handling: 35 watts RMS/50 watts max * Voice coil diameter: 1" * Impedance: 8 ohms * Frequency response: 50-18,000 Hz * Magnet weight: 10 oz. * Fs: 50 Hz * SPL: 94 dB 1W/1m * Vas: 2.83 cu. ft. * Xmax: 1.0mm * Qms: 2.51 * Qes: .61 * Qts: .49 * Net weight: 3 lbs. * Manufacturer model number: B20EC82-51FX-Q * Dimensions: A: 8-1/8", B: 7-1/4", C: 3-1/2", D: 3-1/8", E: 1".

I wonder how this would sound (compared to the other Pioneer 8"),mounted like an open baffle speaker, but used with a rear foam baffle like this:
Technically would no longer be open baffle dipole, correct?
This pjoject, I want this to be cheap and dirty, quick and fun. I want to build an open baffle-like speaker with reasonable midrange, and later mate this with subs
Wiill I get atleast reasonable midrange results using a low power T-amp, running an open baffle design , using either those Pioneers mentioned or Audio Nirvanas, or Fostex 6.5" varieties?
As I understand Open Baffle is best mated with higher power amps?
But is that mostly to achieve adequate low-end response and overall better dynamics?
Will those foam baffles improve any kind of performance using lower power and the single baffle board design?
thanks

An externally hosted image should be here but it was not working when we last tested it.

Those foam `baffles` as you called them are to keep dust and other junk from up in the false ceiling space from falling into the back of the speaker cone I believe. It sure won`t help the bass any and there usually isn`t much bass to be had in a hung false ceiling install anyhow. I don`t see why these should not work OK on open baffles with a T, you meant Tube amp right?
The frequency response shown on the PE website is really ragged in the top end and there is a huge dip at 6 KHz on axis. I`m sure I wouldn`t be able to listen to these and enjoy them. I think you can do better for low dollars with something else.
