These are very nice speakers. I was surprised when I saw the brand name on the box, I figured they were just, some no-name thing. Put them in my Infinity SM122's. Had to trim a little bit, no biggie. They don't move as much air as the originals, when I put my hand to the port in the back, and don't quite have as much boom. But, they are a better, more sweeter, tighter, faster bass sounding speaker. I've had them for a couple of months, and run them everyday, and they do sound better as they break in. A very good replacement speaker.

12" Woofers
Speakers arrived promptly and in good condition. These are replacements for a worn out vintage set and they fit perfectly and sound great. My 40 year old "stereo set" is now back in action.

Pioneer speaker rebuild
Used this as the woofer in an aging Pioneer speaker rebuild. Also used an A-1309 crossover, a T145 tweeter & a W-6028 as mid-range. The overall effect is a bit bass-heavy for classical music, but rock sound great. For classical the bass can be attenuated slightly giving a more balanced sound (tone controls). All-in-all very pleased with the rebuild.

12" Replacement Woofers
Rediscovered my vinyl record collection but my speakers after years of idleness, sounded a bit anemic. Upon removing the cabinet grille, I found the cones to be mostly dry rotted. I ordered and installed the replacements from Simply Speekers, and the units sound every bit as good as I remember. Very fast shipping, quality speakers and reasonable prices. Thank you!

I installed a pair of these woofers in my 1975 Infinity Studio Monitor 120's that I have. They sound great!..............................Response from Simply Speakers: Thank you! Please be aware that this Infinity model requires modifying the cabinet hole to 11" to accommodate the new woofer. We also recommend the 4 ohm version W-1244.

MR. FIXIT
After installation, speaker sounds good. Two points though. Wiring tabs were not marked hot & ground. I'm used to seeing at least one tab with a red dot. Also, the frame was a bit smaller than standard for a 12" woofer and as such, the mounting holes did not align with the existing mount bolts - so I had to do a bit of (re) drilling to install this driver (original driver was a Cerwin Vega woofer subsequently replaced by a Pyle Driver woofer). But, I made it all work - just a little more effort than I planned. ..............................Response from Simply Speakers: Thanks for the review! The terminals are indeed marked for polarity. There is a + and - etched into the tab connectors next to each corresponding tab. It can be difficult to see, but it is there. On some Cerwin Vega models, we prefer to use the W-12PC woofers since they have a slightly larger frame profile that does not require any re-drilling.

Q:
I am replacing the woofers in an old pair of Pioneer S-910 speakers. The hole cutout is exactly 11 inches, will these work for me?
Asked by:
Jeff
- 2/19/2018
A:
Yes, these will fit an 11" hole cut-out but you may need to re-drill the mounting holes in the cabinet. Due to the unique design of the Pioneer S-910 woofer, we normally recommend the refoaming kit part # PIO-FSK-12Ji.

Q:
Will these fit infinity sm120's?
Asked by:
Jesus
- 2/6/2017
A:
Not without modification to your cabinet. The Infinity SM120 woofer is slightly smaller than a standard 12" woofer. You must cut the hole in the cabinet to 11" diameter for the new woofers to fit. Also, please order the 4 ohm version part # W-1244. The original Infinity woofers were rated at 4 ohms. The W-1244 sound great if you can do this modification.

Q:
Will this speaker fix a Altec Lansing model 5 cabinet speaker?
Asked by:
Bradley
- 1/14/2017
A:
We have not used this woofer for your model. The original Altec Model 5 used a 10" woofer built into a 12" frame, so they were a bit of an odd-ball design. We recommend our easy to install Altec foam replacement kit for your repair. See our Altec parts page for 10" foam kits.

I want to put these in my Infinity SM 120's - had the originals re coned a couple years ago - never sounded the same and they rattle . Are these the right choice?
Asked by:
Dave
- 12/21/2017
A:
To use this woofer, you must cut the hole in the cabinet to 11" diameter. Otherwise, the new woofer will not fit. The original Infinity woofer used a 10.5" hole. If you can perform the modification, use the W-1244 woofers (4 ohm version).

Sorry, no. You need an 11" hole to mount most any 12" woofers on the market today. You only have 10.5". You may want to consider keeping the originals by refoaming them with our repair kit part # INF-FSK-12A.

Q:
Will these fit 40yr old pioneer? It has horn tweeter, 2 regular tweets,2 5in tweeters and the 12in woofer. Cabinet is sealed so I guess that's called air suspension or acoustic suspension.
Asked by:
Mike
- 4/19/2018
A:
This will depend on the model. Be sure to double check the original hole cut-out in the cabinet. You need an 11" hole for the new woofers to fit properly. Yes, a sealed cabinet is called "acoustic suspension".
