Default Anyone running 7" or 8" inch Midbass in door

Anyone running a 7" or 8" midbas in the door of a 3?

I am running Focal 165VR 6.5 woofers right now but with the Focal Utopia mids and tweets running passive xovers from my old Utopia 165W3 set they just do not seem to hold up. They get really muddy at upper volume ranges and I would like to put a good 7 or 8 inch midbass in the door. Maybe once I go active I can clean them up but if I can get a nice 8 inch in the door I would go that route.

I have the 7" scan-speak revelator in my door and the scan 12m midrange in the kickpanel. The mids fit in the door easily with a simple baffle. They are getting about 200w rms from a soundstream 1000.2. They are running from 50-500hz right now, although before i had the mids i ran them all the way up to 4000hz which they handled just fine

Good to know a 7 inch will fit. Do you think there is enough room for an 8 inch?

The main problem with using an 8" is that you may have a hard time finding something that large with sufficiently high Qts and 4 ohm impedance to work in a car door and with a car amp. A standard home-audio woofer will not work well. The other problem is that you may not get that much more bass, because even with the usual door leaks, the door volume may build up a lot of back pressure behind the woofer inside the limited volume of the doors.

Yeah I think you could squeeze an 8 in there. Maybe the kicker SS RMB 8?

doesn't that shake the ever living crap out of your door?

you'd have to dynamat behind the plastic and on top of it as well as under / around the driver entirely and have some lovely adapters!

even my freaking 6.5 Polk/Momo's running at 125w rms are silly!

there are a couple frequencies that I'm still working on getting rid of rattles, but for the most parts it sounds great. A lot of it has to do with how it's tuned also. And the fact that I've got well over 100sq feet of deadening in the car. I think i used 3/8 mdf for adaptors.

at what point does it just become inane though?

a properly powered set of components can deafen you if you please. 8" mid's sounds like asking for brain damage unless you just don't plan on using 50% of their potential.

it has nothing to do with volume and everything to do with frequency response. By having a midbass speaker that can play low, you can improve imaging by bringing the bass to the front of the car, add the snap and punch midbass frequencies that so many systems are lacking, as well as clear up your midrange by taking the strain off of it.

What speaker you pick is really just a function of the design characteristics of the speaker itself, not just the size. For instance I have a 15" sub - but I am not a basshead and have less bass than most people's system because of the way it is tuned. I use the larger speaker because it was the best choice for filling in specifically and only the deepest frequencies (50hz and down).

In general an 8" will help a little better with the lower 50-60hz frequencies, but it just comes down to which one meets your needs and will work well with your other drivers. A lot of midbass speakers would not work well for me because they would not play high enough to meet the fairly high crossover point of my 4" midrange driver.

Phoenix Gold used to make a 9" slim mount midbass speaker as part of their Titanium Elite set made by Morel. I haven't read many revies of the midbass itself, but I've heard a lot of great things about the Titanium Elite series in general - as I would expect of anything made by Morel.

Kicker branded some SS 8" speakers I know. Kicker is crap IMHO but their SS stuff is gold.
