Goldwood GM-85/8 Heavy Duty 5-1/4" Sealed Back Midrange 8 Ohm
Goldwood GM-85/8 Heavy Duty 5-1/4" Sealed Back Midrange 8 Ohm is rated 4.4444 out of 5 by 54.
Rated 5 out of 5 by from Great PriceI recapped my 44 year old Fisher XP-9c with some Dayton caps and breathed new life into them. Thought I would tinker some more by replacing the 2 mids in each, one had a small eraser sized puncture( thanks kitty). Really opened up the presence and sound stage, vocals also improved and are noticeably more crisp.Well built with value in mind. I would use these again.

Rated 5 out of 5 by from Excellent replacement speakerFor the price, these were a top choice to retrofit an old pair of 70's era floor units. Great sound, how handling capacity. Did the trick.

Rated 5 out of 5 by from Midrange Speakers Do Serve a PurposeI got a pair of these, crossed it just above 500 hz and it sounded muddy, put it back in the box. Studied some more, then tried it a 1200 hz and now it is excellent. No mud, and since listening to a three way, my two way speakers seem a bit hollow. Don't judge it free air, put it in a speaker enclosure, there is a difference in that too. For sure, the drivers should be bandpassed and let the three "specialists" do the job.

Rated 4 out of 5 by from Great Replacement for Boston Accoustics A-150I needed a sealed back midrange to rebuild a 27 year old pair of Boston Acoustics A-150's. This driver fit the opening (with some minor attention with a Dremmel).I paired this mid range with the Dayton Audio Truncated frame silkie #needed attention with the Dremmel) and the Dayton Audio Classic 10" for a cost effective and very good sounding 3 way system!

Does this mid-range need a capacitor? 

Asked by: JTCOOL63
This will need some form of high pass filter for protection. The type and slope used will be determined by application. Please contact our tech support for more help with this question, tech@parts-express.com or 800-338-0531 x1.

I would like to know if this midrange has a capacitor (or crossover)? If so, what type will will I need? I have been trying to get that information for a while. 

Asked by: JTCOOL63
This does not include a crossover or cap and a high pass is required in order not to damage it. I would recommend a crossover of no lower than 500 Hz on the low end.

i made a DIY tower and looking to connect 2 5" midranges. my crossover is a 4way 12db at 8ohm. if i kook up 2 5" 8ohm midranges would i still get the same 8ohm load or would it drop to 4ohm. can you please let me know what my option is.

Asked by: Vince N
You can only wire two 8 ohm loads together to either get 4 or 16 ohms total. You will have to use 4 ohm mids wired in series, or 16 ohm mids wired in parallel to get an 8 ohm load.

This driver is rated at 92db sensitivity on another site. I looked at the response chart and it looks like it peaks at 96db just above crossover but then behaves more like a 92db driver. Is this correct?

Asked by: Billfromtoronto
Based on the graph I would say 92 is a more accurate number.

What volume should a sealed enclosure be for this driver?

Asked by: MikeR1
This midrange has a sealed back...which means the turbulence inside the speaker cabinet has no effect on this midrange. So, cabinet volume is not an issue.
