Radio Shack produced the Realistic Mach One speaker for almost ten years, beginning in the 1970s. The Mach One 15" 3-way system is considered one of the finest loudspeakers offered by Radio Shack. Over time, many Mach Ones have been lost due to foam rot and old age. This 15" driver features the same warm, thundering sound characteristics as the original, but thanks to contemporary materials and technology will last much longer. Now you can resurrect your set of Realistic Mach One speakers with completely new woofers, giving them a new lease on life! Note: This unit is an exact replica of the Mach One. The Mach Two is a slightly different woofer, but this unit works great for them too!

Let me start by saying the 15 in woofers I purchased for my Realistic Mach Two Speakers are OUTSTANDING The sound is as good if not better than the original speakers . The installation was very simple to do just replaced the two wire end connectors to match the new speakers and the house was a rockin , yes I lock Rock and I like it load enough to sit down behind my drum kit and play as load or as hard as i want and those speakers have no problems keeping up and the sound is clean at that volume as well. if your scan the web as I did checking spearker specs and review the pictures this is the place to buy them from. Thank you Simply speakers you will be hearing from me soon I want to get the original speakers repaired they need the rubber rings that center the cone then im going to add those into my system. That will give me 8 speaker cabnits and a total of 15 speakers in the system , like I said I like rock and I like it load thanks again.

I installed these speakers in a pair of enclosures I designed and built while in college in the middle 1960's. The enclosures tuned to 17 Hz resonance with these new woofers installed, and their performance is nothing short of magnificent.

Didn't think I'd be able to locate these replacement speakers for my two Realistic Mach 2 speaker systems. I'm pleased with simple installation and super quality

I got the Mach I to put in my Mach II speakers since they were reasonably similar spec wise. They went in easily (sans limit ring) and they sounded just like the first time I heard the speakers. Great!

Go-for

The speakers are great, a perfect replacement for my 25 year old 15" woofers. My stereo has not sounded so good in years. Shipping was quick, and the speakers were well packed to prevent any damage in transit.

Speakers arrived without damage and look very similar to the original units. Fitted into the Mach One cabinet using the original screw holes but unable to mount the Mach One cover ring (this is the original black and silver plastic ring which was used to cover up the speaker frame edge to improve fitted presentation due to the Mach One external mount design). The ring has plastic legs equi-spaced on the internal side which are used with tapered plastic fixings to secure the ring to the woofer. I suspect some owners may break these off and glue the ring directly to the speaker gasket, however for originality, I may decide to drill additional holes in the speaker frame to fit the ring as per the original design. Maybe this modification could be considered for new production. With the woofer fitted, sound quality is good.

Received speakers 3 days after ordering! Installed them in under 15 minutes for both. Sounds awesome! I had forgotten how good the Mach Two's sounded! I will definitely use Simply Speakers for all my speaker needs!

15" Woofer, Realistic Mach One, Mach Two, W-1500

Ordered two of the 15" Woofer, Realistic Mach One, Mach Two, W-1500. One of the woofers was defective. Returned it for a replacement, which worked great. After a break in period, the speakers sounded just as they did when first purchased. The bass is room shaking. My movies and music never sounded better. Simply Speakers had what I needed.

Q: I have an Optimus 1000 cat # 40-1130 and the foam has dry rot, will this speaker work for the woofer? I also need a replacement for the midrange...thx

Asked by: Ed Reid - 3/18/2018

A: Sorry, no. This woofer is not a replacement for your model. We recommend the refoaming kits for the woofers and midranges. Order kit # RSO-FSK-15A and RSO-FSK-5L. The repairs are easy, and we have great videos to guide you through the process.

Q: I purchased new foam rings for my Mach 2 Realistic speakers from you. Following video...Does the ring get glued to the front of the speaker as in video for Serwin Vegas or tucked under and glued to the back of the speaker?

Asked by: John - 5/11/2018

A: On your model, the foam surround is rear mounted. See our other instructional videos for instructions on how to do the repair properly to the back of the cones.
