Midrange for Morel-based system

[mindbomb]

Hello

Upgrading to 3Way... Will be working semi-active.
I am looking for a recommendation for a mid-range driver which will require no special box (either infinite baffle cone or simply a dome mid).

It should integrate nicely, sound-character-wise in my Morel-based system (Supremo midbass/MT-23 tweeter), and also be readily available for purchase and international shipment (ebay/parts-express/etc), lastly it should be budgetary as much as possible (sub $180 for pair). I should mention that it'll be initially installed without any pillar/fiberglassing work.

Please see attached picture for my configuration - the midrange driver is marked as "CDM54?" - which is also a consideration (I can get a used pair).
another note: I am not sure the MX22.2 xovers I have truly xover-point at 1.8Khz, it's probably a bit higher.

I'll be glad to hear your recommendations

Thanks
mb

looks like the CDM54 would be a perfect match and if you can source some local and in your budget ??
that's where i would start

CDM54 or 88 seem like the obvious choice here.

I agree, especially if you can get them for $180 a pair. I auditioned an older version of the Morel 2.5" dome and I was impressed. As long as you keep the high pass crossover from the midbass around 800 Hz they are very good. Expecially off axis, in fact they are a little hot on axis. My frind choose the WR4 which is a cone mid but it is harder to install.

CDM54 is dome driver and can not play lower then 500-600hz. LPF should be at 3.8-4.5k.
The higher he play the better.
Try to find 3way morel crossover, like MX-33

Ok, since I am totally unsure if I will be able to get the CDMs for that price, any other recommendations we can think of?

also, the 300 hz I put in the diagram is absolutely flexible and can be upped to 500-600 hz in the HU with a click of a button - no problem here.

Anyone knows what is the _real_ crossover point of the MX22.2 (which I already own)? Would it fit and sound right under the configuration I described??

Dayton RS52's are cheap, the Morel CAM558 is cheap for morel but I don't know much about it.

careful running midbass up to 500hz-600hz in a 3-way setup. All depends on your install and mounting locations as to whether that's going to work for proper imaging. Better bet is to limit midbass to 200hz-250hz and let midrange go from there. Again depends on install. Where are tweeters/midbass located? I love the sound of dome mids but their limited on the low side of things and need to be mounted next to midbass if at all possible.

The MX33 has a 6db/12db lowpass on the CDM-54 at 315 Hz.

depends also on the distance you have between the midrange and midlow.
if you want/need to run the Supremo in the lower end, you may want to use a Dotec/ Hybryd instead
at least, I replaced md88 and I'm doing this but I have a Piccolo as Tw who will help

[mindbomb]

mmm... why is that?
Actually the supremo midbass's are mounted in the (sound deadened, sealed) car doors, and the tweeters and future mids will be located on-axis on the dashboard/A pillars (not much of a distance difference here).
Is that a problem?

Also - regarding the Dayton RS52 recommendation. Firstly, thanks for that. Secondly - isn't the fact that they are 8 ohms will hinder my configuration plan? (impedance mismatch from the cross-over?)

I too was going to upgrade the Elate for a 3-way active setup and looking for the mids. Obviously the suggest was either the CDM-88 or the CDM-54

But my setup kinda restricted my midbass to be crossed at 400hz, therefore, those 2 drivers are out of question.

I was then suggested the MW114s for that they're decently price and good. However, I'm still looking to see if there's any alternative before pulling the trigger.

I can score a few 3.5 inch cone midrange drivers from Audio Development. I don't know much about them but google takes care of that. Say $200.

The CDM 54 is a great driver, though. I love mine.

[rommelrommel]

I don't understand all these comments about the CDM-54 not being able to play down to 400/500 hz when the MX33 passive has a selectable 6/12db crossover at 315hz.

Where did you get that info?

Morel Loudspeakers - Mobile Audio - crossover Networks - Accuset MX-33.4E

their site clearly states 700hz for mid crossing...

he's referring to the discontinued 33.3... Morel Loudspeakers - Mobile Audio - Crossover Networks - Previous models - Accuset MX-33.3
