Eminence Alpha-6C 6" Midrange 4 Ohm
Eminence Alpha-6C 6" Midrange 4 Ohm is rated 4.2857 out of 5 by 7.
Rated 5 out of 5 by from 4 Ohm Eminence Mid-Range SpeakerMost speakers by Eminence are 8 Ohm and not 4 Ohm like these. Installed 4, or 2 per side wired in parallel, for a 2 Ohm resistance with a 4-way active crossover system in a boat. Band passed at 250 Hz - 3000 Hz and they blend in extremely well with all the other speakers. Guitar and vocal reproduction sounds great.

Rated 3 out of 5 by from Improved My Old SpeakersThese two speakers made my old Speakerlab 7C's sound better than they ever did before. The midrange is now clearer and crisper, not muddied like these speakers originally sounded. Also, these drivers appear very-well made.

Rated 4 out of 5 by from Works great in a guitar ampFew speakers fit a 6 1/2 inch cabinet. This one does and it sounds terrific.

Rated 4 out of 5 by from Works great in a guitar ampPut one in a Songworls amp and got a real improvement. Only complaints are I wish the bottom end were a big bigger but that's sort of unreasonable considering the size and target application! Didn't get a dust cover listed in the add but no biggie. Highly recommended for small guitar amps. Its just about impossible to find a 6 1/2 specifically voiced for guitar these days. This one come darn close!

Rated 5 out of 5 by from Great Drivers !!!I have these in the doors of my truck mated with a set of Image Dynamics CD2NEO full body horns & a pair of Image Dynamics IDQ10D4V2 subs. They are AWESOME in this combo!!! My soundstage is VERY Realistic , Dynamic & has plenty of IMPACT in the midrange!!! I was Very surprised how well they keep up with the horns which are 108 db effient. Very HAPPY with my purchase!!!

Eminence Alpha-6C 6" Midrange 4 Ohm

Is there a way I can get a tweeter to fit across the top of this speaker?

I'm fitting it into a Dawn speaker System, but need the highs too. This will fit into the satellite housing that fires the sound up and into a cone.
Asked by: ModEmotions
it's 4 ohm and an auto type dome that swivels mounted on top with one screw and one hole would look nice and have x'over already built in

What crossover would i need with this speaker,high pass/high pass & low pass/2 way/3 way ?

I am putting these speakers in my van and powering them with an old (but good) Rockford Fosgate ,Punch 150 amp.,it has treble and base knobs on it but I do not know if these will pass as a crossover.
Asked by: Nomad
The type of crossover you will want to use is determined by the intended application and what they will be paired with. I would recommend a high pass filter regardless, probably something around 80 Hz.
