Tang Band 25-302SH 1" Shielded Neodymium Dome Tweeter
tweeters added in series for SPL?
If an additional unit is added in series, does the crossover need to be modified?
If two 8 ohm tweeters are used in series, the result total impedance will be 16 ohms. Depending on the crossover design and the location of the component in that crossover, values will differ from those selected for a single 8 ohm tweeter.For example, a series driver pair with 16 ohm total in a first order crossover will require a series capacitor of 1/2 the value of the same network with an 8 ohm single tweeter total. Other types of crossover may be different. the two in series will likely be 3db louder or more efficient.

Off axis response and within a car environment?
I would be running these in a 2-way setup, crossed at 2.5-3Khz. The woofer has a sensitivity of 89dB and is 8ohms and will be wired in parallel with the tweeter. The amp is 4ohms and has 87watts RMS per channel. First, how is the off-axis response of this tweeter, and second, would this tweeter do well in a car environment within this type of setup?
The off axis projection of this dome is not given however traditionally these are very open. This would be improved in a car because of the reflective surfaces. Remember the lower the frequency the less firectioal the sound is. Your tweets can be installed anywhere you desire to maximize your sound.

Would recessing this tweeter affect quality?
I came by some great cabinets that were covered on 3 sides with cloth and all "bad" rear mounted drivers.I would like to front mount my new drivers and recloth the cabinets I would imagine that I need to find an 8ohm tweeter that will not rub or protrude into the tightly fitting cloth? I have used thes before with great success but i'm not sure if recessing the flange slightly to flush mount will change the tonal quality? Thanks.
No flush mounting these Tang Bang tweeters, should make no difference in their tonal quality. The only difference I would suspect could be in phasing with the other speaker in the cabinet and that would be absolutely minimal.

ECI Image II (Minimus 7's?)
I have a pair of ECI Image II's that appear to be exact replicas of the Minimus 7's, I was wondering if this tweeter would replace the original SD-60 8 ohm without needing to change the crossover? The mounting mod is not an issue.Thanks! Joe
Your Minimise 7 speakers first appeared. At Radio Shack in 1978 and have continued to be loved by those who own them. They use a simple 50mfd electrolitic capacitor as the crossover so not much hi-tech going on for tweeter protection. Yes, I think this would be a good replacement assuming mounting is not a problem. I don't remember the frame.
