Senior Manager Regulatory Affairs
These speakers are a perfect replacement for the completely worn-out woofers in my Radio Shack Minimum speakers. Sound is perfect.

Retired Process Manager
The 4" Mid Bass speaker was used to replace the original speaker in a Pioneer bookshelf cabinet which was their first bookshelf speakers in 1977. The space was a square area with specific mounting holes that the speaker needed to mate with. The replacement speaker fit and performs superbly - there is one 4" mid-bass and a 1" tweeter in each enclosure. They are like new, again.

Nice speakers but do not have the true deep rich bass sound I once had compared to the original Realistic woofers. Now don't get me wrong, they still sound good but NOT for bass. These are more suited for mid-range type installations. Not bad but definitely not what I was hoping for. To me, Simply speakers is still a 10 star rating though. A DEFINITE RECOMMEND!!! I PURCHASED MANY OTHER SPEAKERS AND THEY ALL WERE ABSOLUTELY PERFECT IN SOUND AND DESIGN!!!! BUY BUY BUY FROM THEM BECAUSE ITS WORTH EVERY PENNY!!!!!!!!!!!!!

Replacement midrange for ar48s
I picked up a pair of Acoustic Research ar48s as a repair project. I found that one of the midrange drivers had aa open voice coil and couldn't locate a replacement. SS recommended this driver as a substitute. I bought a pair to have and replaced both midrange. At first they sounded a bit off but as I broke them in they are sounding better and will be a great midrange as the crossovers reform to normal.

Great products and servivr
My 50 year old Marantz Imperials 7’s both had dead midrange speakers. Marantz said they could not supply them. I talked to Tom and herecommended the W-304-8S. It would require a little woodworking with a trammel circle cutter and my drill press, but I was desperate . I ordered two and they arrived in two days. I had forgotten how good these relics sound. Top rating to all involved. Thanks guys

Brought my Radio Shack Minimus-7 speaker back to life!
One of the drivers split open on my old Radio Shack Minimus-7 metal cabinet mini speakers,,, I thought I'd have to toss them but then I found Simply Speakers! For a reasonable price of $20, I ordered a new driver and I'm back enjoying these great little speakers ! A perfect fit and the sound is very balanced between the old good driver and the new driver. Outstanding !
