Ive been out of the scene for a year or more, due to my daughter being born, but Im rebuilding, and have a set of image dynamics cd1e horns to install, I have some 6.5" midbass I can use, but want an upgrade and have tons of room on my doors. I need a midbass that will work in sealed (as sealed as a car door can be with working windows) doors with 100 wrms per side.
I need them to be able to handle from 65-1.5 or 2 k hz or so

mounting depth isnt really an issue either, ive got at least 6" if not more, if the driver is appealing enough Ill make more room

I can fit either 2 6.5"s, 2 8"s, or a 10" in each door, so hit me up with some suggestions

Ive looked at dayton rs 225s, the sls 8" and many more, but I dont know whats been going on since Ive been out of the game, so there may be some new, good, affordable options
and yes, price is an object, budget midbass only need apply


edit*****
i dont know the specs of the id cd1e crossovers, but Im assuming I need a 4 ohm driver here

I cant get IDs site to work properly for me.
I emailed them late in the week, havent gotten a response as of yet

if budget is an issue then you need to state a budget

its not too specific, lets say <$200 new, but like i said, if something seems perfect Im felxible

Peerless SLS 10" mid was the talk when I was looking.

I have a pair of the rs225's like new and they sounded great. ...hint

Kicker SSMB8's. I have them and they can pound!

those are dedicated midbass and i'm not sure if that is what the OP is going for. I have a feeling he's not running a 4way active setup.

this is for a 2 way, midbass with horns..
thats the plan
I have some really good 6.5" drivers that can fill in between the midbass/horns if needed, but with the horns rolling off around 1500 Im trying to find a really good midbass/low low midrange driver than can work

Im trying to keep this simple, but can go three way if needed

Ive looked at the sls, but not saavy enough to figure out how well they would work for me

the daytons have always been the first thing that came to mind for this for me :)

the 10" rs 270s look like a possiblity, but the fr being maxed at the horns rolloff makes me a littlwe concerned
I dont have the specs on the crossovers from ID, but Im assuming I need a 4 ohm driver to work here, Im going passive with eq at the moment, active isnt possible with my current non existent processing

from everything Ive found currently, the rs 225s seems like the best, easiest option

If this is for a 2-way, you should know that the Peerless SLS is best kept below 250hz. It CAN be run up to 500hz or so, but 250 seems to be a good number for them.

You may be better off with a pair of RS225's.

Here is some info on the horns from ID's forum. You may need to join to see it.
http://www.imagedynamicsusa.com/forum/index.php?showtopic=2152

The cross over is 700hz @24db it also states they work with either 4 ohm or 2 ohm

How efficient are the horns? I think you might want to look at some high efficiency pro audio mids, esp if you need them to play up to 2k. Look at the B&C 8NDL51....very low distortion and can pound....makes the SLS 8 look like child's play. ;)

I'd say RS-225 4 ohm could do some serious work. RS-270 if you really want to go that big could also it that job well.

thats great info, I did some searching, but never went to IDs forum for some reason
If this is what Im getting (havent arrived yet) then my ot\ptions are a lot more open than i though

I thought the cross was at 1500 previously

since you have a lot of mounting depth try these the will easily fill the range specified and are very very efficient. B&C sounds always pleases the ears. Dont let the low xmax fool you.

Like new RS225's $80 shipped. They're stored away and doing nothing.

Keep in mind the larger the cone of the driver, the worse the top end off axis. That means a 10" HE midwoofer is only good until about 1.4khz before it starts to beam. Sure you CAN use it, but it doesn't mean it will sound good. An 8" is good ~ 1.7khz.

Doors are terrible spots for any driver in a car, albeit an almost necessary install location. In a one-seater your side lower door is almost 90* off axis. :(

Im going to be making a fiberblass pod for these, that will connect the door panel to the soor frame, with hopefully more on axis aiming
Im excited about this, finally doing a real front stage in my car

looks like Im going to go with an rs225 per door, upgrades later if so needed
