what drivers are best? thinking of a DIY project

Morel, ScanSpeak and Seas all built very good drivers. Here's a good place to shop: (https://www.madisoundspeakerstore.com) Studying the very comprehensive specs, included in the descriptions, should help you best choose your combo.

Are you thinking a single driver speaker or multi-way?
Passive or active crossover?

DiyAudio.com is the place for that. I'm scratching the surface, looking at building a 4-way active system. I started a couple of threads there you might want to check out. I use the same ID there. Especially the Bass Section thread. A lot of reading.

Lenardaudio.com is a good primer on a number of considerations, but he does believe in 4-way active as THE way. Of course there are many ways, like everything it seems to be more about implementation and tradeoffs. But it's a good read/intro to a number of important aspects.

Cheers!

ooops sorry

I am building a single driver system nothing too complex

Lowther is too pricey but some feel the midrange on the Fostex is "shouty" so I am asking around

I will go to the sites you guys mention and thanks

I may post again as I have a long road ahead...
