Who loves their mid-bass?

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.

Alpine SPX-17MB, had them for a lil while, did a nice job keeping up to the subs

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:
Speakers by Morel

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?

I used to run a pair of a/d/s/ 336is.2's in my car.  In fact they are still sitting in my closet till I finally sell them.  Although they were great sounding speakers, I can see why you need some midbass.  They really did lack the low end.

BTW, I don't know if you are still considering them, but the Extremis mids will run just fine IB.  Also, I doubt you will have to run a high pass on them since they have so much throw. 

Vas is pretty much meaningless by itself.  You will generally need other parameters to tell what type of enclosure to use.

The Extremis woofer is larger than the Morels. The Morels will drop right into my stock location. So unless there is a really good reason to go with the Extremis over the Morels, I'm going to stick with either the H6.1 or the MW-164.

So am I to assume that I do not need to build some sort of enclosure for this speaker. Use the door as the enclosure?

I'd go with the Extremis drivers if you have don't have that steep crossover that you would need for the Morels. You also could use the doors enclosure instead of having to build a box inside of it so it would be alot easier in the long run.

It looks like the mounting depth is 3.63 inches so you would probboly have to just make a MDF riser (1/2 inch MDF) so that the Extremis drivers would fit in your doors depth wise.

customsuburb, are you suggesting that the Extremis is a better choice? My issue with the extremis is that it is 7" overall in diameter. I dont think this will fit in my stock location without modification. I am not against modification if the Extremis is the driver I should go with. Also, I've determined the my head unit can be set to run a 18 dB slope.....

I will run my sub from 80 Hz down, the mid-bass from 80 to 350 Hz, and the seperates from 350 Hz and up.

My Cadence comps are okay when it comes to low frequencies, but you can tell they have a hard time. None at all for frequencyies higher than 40 Hz. Anyways, the CDT Euro series has fantastic midbass. Extremis is great too.

You've heard them?  In what kind of installation?

My concern now is that these drivers are 8 ohm. I wonder how they will perform. I was going to use an amp thats rated at 100 W @ 4 ohms. So that would be 50 W @ 8 ohms. And these speakers want to see 150 W rms......crap. I need more power for these speakers, dont I?

run them parallel. You are going to have two of them i guess, so you would achieve a 4 ohm load, in which you can find an amp that will do 300 @ 4 easy. If you are getting 4 of them, one for each door (i don't know the car), then you would get one monster 4 channel amp that can do 150 x 4 @ 8 ohms, or bridge it and do 300 W x 2 @ 4 ohms. Either way your okay. Give US Amps a call lol. I never heard the extremis, but based on what i've seen of it, and what i've heard, it should be like all other adire products - nothing shy of fantastic

If I run them in parellel then I will be giving up my stereo imaging for the midbass frequencies. Would that be noticable? I think I will just use my MB Quart 6" from an old component set. That way I can maintain the 4 ohm load as well.

Parallel is an awful idea. Midbass should not be mono.

Frequencies above 80Hz are directional, so placement of midbass drivers is crucial for proper imaging.  Stereo or mono will work, but yes stereo is better especially if the high cut Xover point is in the midrange bands (I believe yu are planning 350Hz?  I'd go stereo.)   Why do you think they need to be 4 ohms?  8 ohms (or any load, actually) is just fine.  Choose and setup your amps and crossovers properly and the impedence of the driver does not matter.

you'd be amaze at what those drivers can do with that power. the rating is typical the thermal protection level, above which you will damage your speaker, you can usually get a lot of sound from a driver with that power, I also think youd get more than 50 watts, probobly closer to 60-65. go with the adire's though, get some koda 8's. modify your door, you will be very, very pleased. I'd run those up to 400 hz too. good luck

Thank's for your input guys....

I just took a look at the MB Quart speakers that I already have, just to see if they would be a good choice for the midbass. I am not sure how good they are. They are QM 169TX-3.

What do you think? Should I give these try and decide or is it not worth it? Also, does anyone know about the availability of the Adire Extremis? Are they only available directly from Adire?

i've just ordered mxt thunder 404 for for my 4 speakers, but thinking about using components in the back, for more bass. the amp listed to put out 50W per channel, but a lot of people say it's underrated. can i still get something decent out of that much juice?

bump^^^^

spilot, I am not familiar with the components you are talking about, perhaps posting a new thread with your questions may get more of a response.

I am still contemplating on weather or not to stay with the MB Quart or go with the Morel's. They are the same size speaker. The MB is 4 ohm, the Morel is 8 ohm. I will be using an Orion Xtreme 3752 to power them. I cant find any wavelength analysis for either speaker to see how they may perform....any sources out there for this information other than the manufacturer?
