Morel CAT 308 1-1/8" Soft Dome Tweeter
I'm looking for a replacement tweeter for a pair of Bose 201 series II bookshelf speakers. These Morel Cat 308 tweeters are my first choice. What do you think? Pros and cons? What about the stock crossover, will it be adequate? Any other suggestions?

Will these tweeters handle a 400 watt per channel amp effectively? I have 3-way speakers with a 12" woofer and 6" midrange and my tweeters blew on me..... Thanks
Tweeters will only get about 10% of the total input power of a system depending on where they are crossed over. These have a high thermal limit so they should work fine as long as the crossover point is 1,800 Hz or higher.

Can someone explain the differences between the morel 308's and the 408's for a 3 way party speaker set up-market with morel soft domes as the mids. I like the enclosure of the 308's, but wondered if the 408's are better suited SQ wise.
While I cannot speak for sound quality between the two, they are very similar other than magnet type. The 408 has a slightly higher Fs which will reflect a slightly higher crossover point, as well as lower power handling. If you plan on cranking these up from time to time thie higher power of the 308 will probably be your best bet.

Do tweeters need Zobels? I'm matching these with the RS150P-8 in your .23 cu ft knockdown box, together running off a sealed sub with your 12"DVC woofer, crossed over at 135hz. I came up with a .33 cap and a 6.5 ohm resistor for the Zobel.
Tweeters generally do not need Zobel networks.

Are the diaphragms of these tweeters sealed from enclosure.
Are the tweeter diaphragms able to acoustically couple with midrange or midbass driver(s) that share the internal airspace of the enclosure, (acoustic suspension) if a separate internal enclosure is not built to isolate the tweeter?If so, (the diaphragm can couple), then what might a comparable ( BL product, Nom. Pwr. Handlg., Voice Coil Former & Wire config., B Flux Density, & BL Product ) Morel unit to consider in it's place ?Thanks Very Much.
There is an internal chamber with the Morel. It is sealed from the air space of the speaker cabinet. You would never want drivers of separate frequency ranges to share the same air volume. In this case, the mid or woofers excursion would literally blow a mid or tweeter diaphragm out of their frame if no enclosure was behind them

How well would this mate with a em428 4" midrange and a dayton st385-8 using a dayton260-152 crossover with a dayton st385-8 15" woofer
I would like to make a 3 way system with this using an adcom 555 amp to drive it the amp is rated at 200 wpc, like the ribbon tweeters due to the extended frequency response but they are pricey for the higher wattage ones and I can't find the formula for a woofer at 300 watts rms means you need a mid at such and such wattage and your tweeter could be this wattage to match. Any teckies have any thoughts on this?
As for "how well" something would sound, with or without something else, I'm afraid that is a matter of opinion. You may prefer one thing, I may prefer something different, and your neighbor may not be able to distinguish one from the other. As for power handling, in any system, the woofer is going to consume the vast majority of the available power, the midrange would be next, and the tweeter will have relatively little power left available to it. Unless you're bi- or tri-amping, I wouldn't concern myself too greatly with the power handling specification on the tweeters.
