The tweeters on my Podium Pro 15DJD speaker have been damaged. I can't find the same replacement for them so it looks like I will have to put in different tweeters. The speaker is 8 ohm, 800 watt RMS 1600 max. What specs do I have to look for in a compatible speaker? It has to be the same resistance but how will a difference in wattage affect the speaker? I am new to speaker repair, thanks!
