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 4.4231 out of 5 by 52.
Rated 5 out of 5 by from Awesome Midrange for great price!!To me this is a very loud mid range for the price, and it looks high quality

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!

Rated 5 out of 5 by from Puncy and articulateThese fit the speakers I upgraded (see picture). The mids I took out were cheap and sounded bland. Now, these speakers sound more open and natural...and a bit louder. I am using the existing crossover points...will upgrade later. The speaker is a sealed enclosure, so I needed a sealed back midrange driversPROS: Strong architecture/large magnet. Very linear and loud when driven...no noticeable harshness. Power rating. Looks professional.CONS: I measured the cutouts before purchasing, but didn't realize how tight the tolerances are.

Rated 4 out of 5 by from Refreshing ChangeBrought my old 4 ft. tall Yamaha speakers back to life. There is a significant change to the midrange. You actually here more detail than the previous o.e. Yamaha midranges with there mediocre magnets.

What are the TS Parameters?

I've order the DA DC28FT and DC250 along with the Goldwood 5" to rebuild a 27 year old pair of Boston Acoustic A150's. Recommended XO Frequencies?
Asked by: Auburn 81
For this combination I would go with crossover frequencies of 625 and 5000 hz like the crossover in the link belowhttp://www.parts-express.com/pe/showdetl.cfm?partnumber=260-154

Graph Question

This speaker shows a 15 db peak as it enters it's range, about 500 to 1200hz. Will a crossover smooth those bumps ? I did test it, it does sound very much better than my two way speakers in the mid band but seemed to ssssst on cymbal crashes. So I hope an 800 to 5000 hz 12db band pass will keep that mid sound, then pass it on to a soft dome at 5000 hz with a 12db high pass.Piano and Sade sound GREAT on this one. But if I can do better then I can go as much as $20 each for a better midrange.Main question, do crossovers smooth out the curves shown on their graphs ? And is it worth the trouble to use an open back mid and tuned box ?I have two Realistic Mach 10 boxes , 1.8 cf, and made an adapter plate to put a midrange where the 8 inch driver was, then put a 10" driver where the 10" passive radiator was. The OLD paper cone tweeters that are in it are so muddy I could puke, I'm gonna have to put those soft dome tweeters in there.
Asked by: poundasound
The bump is due to the sealed back on the driver. A crossover will help this to an extent but likely not completely flatten it out. The sizzle you are getting in the upper range would be helped however.

What size are the terminals?

Asked by: R.J. Maurer
Terminals? Does not matter what size they are since you will be SOLDERING the wires to them. Trust me. And restrain them with tie-wraps to the speaker frame. Zero-defects.

Power rating??

I have purchased 2 of these and they seem to be working well. My question is about actual power ratings. Online you show the power rating as 60 RMS/100 Max, and also 60 RMS/120 Max. Your catalog shows them at 40 RMS/55 Max. What is the actual rating?
Asked by: Bent Mt Dave
I am running them in a 3 way configuration with a 800Hz crossover point. I am also using an L-pad (they have a high SPL). I have pushed them hard with my my HK 120 WPC amp....w/o any issues. If I turn up the L-pad, they are too loud and seem to distort when pushed near 100w.

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.
