What 5 1/4 component sets will fit front E93 conv. with custom modification ?

Why 5 1/4?

[cvsnowboarder]

Well I thought if my installer could somehow custom mount 5 1/4 I figured the more cone area the better . Would it be possible to fit Focal K2 5 1/4 in there ?

Sometimes its the quality
The Morels are some of the best.

If you really want a lot of cone area the Jehnert Panels
are a possible solution if you want to spend that much on your
car.

See the Jehnert site.

I don't wanna spend that much. I just want to know if a competent installer could squeeze 5 1/4 Morels/ Focals/ Rainbows in the front doors of a e93 conv.?

Only top-mounted, which means loss of OEM look and modifications to door panel (making openings larger and possibly cutting into the passenger-side door handles). It definitely requires an experienced installer. Mathematics mounted some Dyn MW152s that way. I would look up the mounting depth of the Dyns and that would be the not-to-exceed number for your search.

Only reason to mount 5 1/4s is to get more mid-bass, in the 100 - 250Hz range. Otherwise, they are inferior to 4" speakers because of "beaming", which means the higher frequencies emit from the speaker in a narrower cone than in a 4" speaker, which may result in dips in the frequency response. A successful installation can be done, but it will probably require EQ and a tweeter that can be crossed over pretty low, say at 2500 Hz.

I was looking at some 5 1/4 sets lately, and I was looking for pure SQ with the addition of beefy midbass response. My three top contenders were:

JBL Gti 560
Boston SPZ50
HAT Clarus C51-2

Note, the JBL and Boston sets are long discontinued, but can be had second hand. Their grilles are big and would probably require some major creativity to make them fit.

okay, thank you.

I agree that it is not wise to put a 5 inch speaker in place of the 4 inch. You can get plenty of midbass from the under seat location

Sense the 4 inch speakers are mounted on axis pointed across the cabin. You will get flatter frequency response by sticking with them
