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!

Eminence Alpha-6C 6" Midrange 4 Ohm

closed cab. states; 0.09 feet/cube. Is this correct? I doubt the speaker will physically fit into a cab. that small. I am considering it in a 3-way with twin ring tweeters (270-252) and gw 1058. Both I use and love in other projects.

Asked by: fisherchuck
As a midrange the cabinet volume will have minimal effect on performance, especially if crossed above 250 Hz.

I am replacing a Samson studio monitor (Resolv 65) woofer, is this one close to what I need? According to the options at the left of the product selection, It is the only one.

Asked by: Dave2015
I would not recommend this woofer as a replacement for that monitor. Generally studio monitors use proprietary drivers so finding after market replacements can be very difficult. I would recommend contacting our tech support for more help with this, 800-338-0531 x1 or tech@parts-express.com.

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.

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
Maybe...I have used metal grilles to give a little extra depth above a speaker and a fairly stiff frame to attach a tweeter. It usually requires some "backwoods metalwork" to get the tweeter mounted, but any unfortunate details on your build would not only be covered by the tweeter (as mine have been), but might not be easily visible at all.I could not find an exact-fit grille, but the 6 and 1/2" grille I added below would work. If you center everything and eliminate any buzz or rattle problems (from grille parts or unsecured tweeter wires) you will get what you want.I will be watching to see if someone offers a mor elegant solution, but this one will work.
