GRS 5SBM-8 5" Sealed Back Midrange

The GRS 5SBM-8 5" sealed back midrange speaker is a perfect replacement for many popular 3-way and 4-way loudspeaker systems produced during the last couple of decades. The driver's enclosed chassis eliminates the need to provide a separate sub-enclosure; the 5SBM-8 is a drop-in alternative driver for many applications, as well as providing excellent performance in new projects, too.

GRS 5SBM-8 5" Sealed Back Midrange
GRS 5SBM-8 5" Sealed Back Midrange is rated 4.2308 out of 5 by 13.
Rated 4 out of 5 by from Nice quality soundI bought one of these mids to replace a blown speaker in some old Fisher STV-884's. I liked the sound so much I bought a second one to put in the other speaker to match. With new Pyle bullet tweeters, these nice mid-ranges, and some new GRS 15" woofers, my 30 year old speakers sound crystal clear- and so called critics say 80's Fishers have weak crossovers. Phooey! Sometimes these old speakers just need some updates. I now have great main speakers for my 5.1 system without breaking the bank. Thanks Parts Express!

Rated 5 out of 5 by from Wicked buy!I installed these in my heavy duty 3-way speaker cabinets with a GRS 12PF-8 12" woofer and a Goldwood GT-1188 piezo compressor with a GT-400 waveguide. nothing but excellent sound, the grills do come off with relative ease being careful with a very small jewellers screwdriver and a little bit of patience and time (Avoid taking off/tearing the surround with the grill) but it worked and look rather good too. Only thing to watch for is when it says 5" midrange, read all the dimensions listed in the specs. this will fit perfectly in a 4" hole with a little bit of fine tuning with a dremel tool. Thanks Parts-Express, so far nothing but 5 star ratings with you guys!

Rated 5 out of 5 by from Best Paper Cone Mid range I have heardPaper cone speakers are the best, all things considered. Low Cost, and Great Sound. What more can you ask for.Also, I paired these Mids with a Goldwood GT-25 4" Cone Tweeter for the Highs and I couldn't be happierAdditionally, I removed the Grills (Used a paper clip made it into a hook and then snaked it through the holes and grabbed the hook part with a pair on needle nose pliers and pulled) (Ripped the first grill into pieces because it is hot glued into place, i thought they would be using to that black tack stuff. I was wrong. Therefore, for the second one I snaked the paper clip through and got it ready, and then used a hair dryer the outside edge of the grill and then gently pulled and the grill popped right off.Hope this helps anyone wishing to remove the metal grillsEnjoy

Rated 4 out of 5 by from Strongly reccomended.Well builted midrange, with a useful metal grille, it sounds natural and with good efficiency, highest price-performances ratio. So far so good.

Rated 5 out of 5 by from Great replacements!Bought 6 of these to replace 2 in some 19 year old Cerwin Vega! RE25's and 4 in some 30+ old Fisher DC15's. These may be cheap but make a big difference over what was stock speaker in both cabinets. I can actually now hear the mids and can turn up the bass without washing out the mids. My neighbors love them.....LOL.

Rated 3 out of 5 by from Better then stock, but not much moreI own these mids and a pair of Goldwood GM-85/8 Heavy Duty 5-1/4" Sealed Back Midrange. The Goldwood's are much better and sound smoother.PROS: Low cost, grill, 89db SPL, decent replacement for most midsCONS: Easily blown, at louder volumes this mid sounds "distressed" and not happy playing loudCONCLUSION: These lasted about 5 months before dying. I really think they are cheap mids dressed up to look tough (with the grill). Go with the Goldwood GM-85/8 Heavy Duty 5-1/4" mids (4 or 8 ohm available). I have these in my other project and they still sound amazing.

Can I remove the grill? Prior reply says "not designed to be removed." But can I remove it if I want to? (It looks like it could be popped out of the frame.)

Asked by: Marvin111
The grills on these midranges are glued on so with the right technique they can be removed.

HI, PE. Will this midreange speaker fit into Cerwin Vega D9? Thank you

Asked by: pur40422
Unfortunately we do not have a cross reference available for this type of thing. This midrange will fit into a cutout that is 4-1/8" in diameter and will handle a low crossover point of 600 Hz or higher.

Sealed Back Replacement

Can you replace this sealed back midrange speaker in a vented cabinet with a non sealed unit such as a Dayton with similar specks?
Asked by: TonyD
If you replace a sealed back midrange with an open back speaker you will still have to create a chamber behind the driver to prevent the woofer from distorting the cone. You can use something as simple as a dixie cup glued behind the driver for this.

What size are the terminals?

I need to know whether they are 3/16, 1/4, etc so I can buy the right connectors.
