I am tryin to select a mid-bass driver to complement my ADS 246is component speakers. The components will be mounted in kick panels, the mid-bass in the door. Size is not a major issue but 6.5" will fit perfectly.
Any suggestions?

Morel MW-164, Adire Extremis
Not necessarily in that order... Both are REALLY good drivers for that application.
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Why do you suggest the MW-164 over the MW-166,MW-167,or MW-168?
These Morel speakers will drop right into my factory door location. I'd love to get the Adires though....

I only said the 164 because it is really a neodymium motor structure replacement for the MW-162, a perennial favorite of mine, which I have used with GREAT success in car, home, and multimedia applications. All of the 6 inch MW series woofers from Morel are very nice drivers, though, and really, you probably couldn't go too far wrong using any of them. One quick word of advice, though... use a STEEP crossover on the hi-pass - at LEAST 18dB, or you'll beat them to death in short order in a car door... (also speaking from experience)

The frequency response of the MW 164 is 40-6K Hz. I plan on crossing around 350 Hz. Would I still need to crossover with an 18 dB slope? My system can only handle 12 dB slopes unless I add a passive inline cross.
The A/D/S will then see 350-20K Hz. Unless you suggest using the MW-164 to make up for A/D/S's weaknesses in the mids...

The Morels are very nice woofers.  12db slope should be Ok at 350Hz.  I use a set of Scan Speak 8545's with 12 db/oct at 250 Hz, but I'm about to experiment with the Extremis drivers.

OK, I had to re-read your last post a few times... If I understand, you are planning on adding a mid-bass to run 350 and down... is that right? If so, then yes you still need to run a high-pass crossover on the Morels, especially if you are looking to run down to around 50 to 60Hz - i.e. the midbass running 50 to 350, the mid 350 to (built-in crossover point) and tweeter (built-in crossover point) and up. I really would not recommend overlapping the Morel with the ADS... bad idea!

Okay, that makes sense, thanks!
I've been checking out the different drivers by Morel. It seems that the MW-164 is the one with ceramic magenets only whereas the H6.1 has a combination of ceramic and neodymium magenets for about the same price. the MW-164 is a poly-coated paper cone with a 3" voice coil wheras the H6.1 has a DPC cone with a 2-1/8" voice coil.
Does anyone have any experience between the two? Which would you suggest? Here is the site I've been looking at:

I guess my next question has to do with properly mounting these speakers. By comparing the MW-164 and the H6.1, the major difference is in the Vas. The MW-164 has a Vas of 0.39 cu-ft whereas the H6.1 has a Vas of 1.06 cu-ft. I plan on mounting these speakers in the stock location. Which would be better for my application? Or which will sound better? Or, what do I have to do to make either one of these sound good? Is an enclosure necessary?
