Advice needed for replacing tweeter in wharfedale diamond 8.2

[availlyrics]

Dear All.
I'm planning to turn my old wharfedale diamond 8.2 bookshelf to tower type. with active crossover. As those tweeter had been repaired for coil damage, I'm planning to change its original tweeter to something different like -

Option A-
Mcm Audio Select 53-1080 - 1" Soft Dome Tweeter
Impedance: - 8 ohm
Power Rating Nom: 30W
Sound Level SPL: 92dB
Frequency Response Min: 1.5kHz
Frequency Response Max: 20kHz
Power Rating Max: 60W , RMS 30W

or Option B-
Doogesound DE17N-06 NEODYMIUM TWEETER
1) Material : Iron & Plastic
2) Sensitivity(1W/1M) : 89db
3) Nominal Impedance : 8 Ohms
4) Power Capacity : 15W RMS
5) Frequency Range : 1.4KHz-20KHz
6) Magnet Size : 30mm
7) Diaphragm Material : Thin Silk
8) Voice Coil Diameter : 35mm
9) Voice Coil Type : Round Aluminum Wire
10) Size : H/66mm, L/90mm
11) Mounting Hole Size : 60mm
12) Magnet Material : Neodymium N38
13) Frame Thickness : 3mm

Above are the only specifications /details I could find. Imp parameters like resonance freq. , freq response at what +/-db are missing. My only reason for opting is that these are readily available in my area.

Please excuse me . I'm taking baby steps towards designing speakers , Please help me to decide between Ferrite vs neodymium, 26mm copper vs 35mm aluminum voice coils and 30W vs 15W power handling.

Thanks in advance,​

Please help me to decide between Ferrite vs neodymium, 26mm copper vs 35mm aluminum voice coils and 30W vs 15W power handling.

You are obviously looking for a budget tweeter, but the low price MCM driver does not inspire me.

I would go for the neodymium magnet for its combination of strength and compactness and the aluminium voice coil for its light weight and large diameter. The 15W rms power handling is adequate for a tweeter which will only have to handle a small percentage of the total system power and is probably the more honest figure. The sensitivity of 89 dB seems the better match of the two.

Without the specifications of the original Wharfedale tweeter, matching a replacement is rather hit or miss, but your active crossover should be able to compensate. The lower end of the tweeter's useful frequency range of 1.4 kHz is probably at or close to the tweeter's resonant frequency.

Thanks for clearing my confusion , I will go for neodymium Doogesound DE17N-06 .
