- Drivers--sometimes called "speakers"--produce the sound in your speaker system. Sometimes they go bad due to defects, age or even abuse. Such was the case with these Realistic Nova-6 speakers. The tweeters had failed. After a number of conversations with Parts Express, it seemed that the best replacement they could offer was the Dayton Loudspeaker Co. #275-055 titanium dome tweeter.
From what I have read, Radio Shack's Realistic Nova series speakers are generally well regarded. The surround on the woofers also appears to be very robust. Despite their dated looks, I would certainly recommend them.
A Technics SH-4020 "audio timer" makes a cameo appearance in this video. This is basically a glorified electric timer that can turn a stereo system on or off at a prescribed time. Since a simple light timer could do the same for a lot less money, these aren't terribly common units. This one supports worldwide voltages, 50/60 cycle correction and uses 24 hour time.
The receiver driving the Realistic speakers in this video is an Optimus STA-795.

I have a pair of these that I've never had to replace or repair. I bought them at a yard sale in 2004 so I've had them for 8 years. They are the really great speakers and they seem to last a long time.
Bought the same speakers for $20. they looked perfect and the surrounds looked perfect. When turned up a little I started hearing a loud popping noise out of one of the speakers on hard bass notes. I watched the speaker closely and saw that a split in the surround showed up on the hard bass punches. They look perfect when at rest but you can see the split if you really focus on watching the surround. I am replacing both the woofers and the tweeters from some Daytons from Parts Express.
that woofers been replaced its not origional
That explains why the 200w amp didn't kill them
Nice work. And looks like another piece of equipment followed you home...
I would also like to maybe see a video in the future on re conning, that would be interesting.
These speakers are pretty odd looking, very very 70's, but they are good looking in their own type of way,
perhaps you mis-spoke or I mis-heard. you say the new twtr range starts at 5K Hz. With the XO @ 4K, you'd have a response dip between 4k and 5K Hz. Actually, twtr 275-055 freq response is listed @ 3K Hz and up. Its Fs is ~1600; a single capacitor (as the XO) will provide a 6 dB slope. A general guideline for such designs would be to set the XO point to be twice the twtr Fs to insure protection from lower freqs it can't produce. Good job and enjoy.
Those Nova 6 have padding resistors in the X-over for 3 tweeter levels low,norm,high
another thing to watch out for. is if someone has been working on a speaker. and if they didn't have it hooked up correctly. its a good chance they didn't know what they were doing.and it would be a good idea to check the speaker specs. and try to determine if they had removed any insulation and replace it correctly.I found some of those once.and if you have built your own custom speakers before like i have.and it looks like you may have. you can tell something is wrong.as soon as you hear them
Nice set I have a set from 1973 I got at a goodwill store for 10 bucks back then they were selling for 39.99 in the old radio shack book . those speaker run forever if not abused.
Nice repair job! Great stuff!
Keep it up William!
The Advent /2, /3, and /4 series of speakers use the exact same woofer. The quantity and quality of the bass is so good I find I don't need a sub.
I just watched a Parts Express video on the BS36 LCR Speaker, and at the end this video popped up as the Up Next Featured Video.
BTW, thanks for the shout out.
i love the look of these speakers, very 70's
gotta love sealed speakers with cloth surround woofers
Oh god, I have a maybe 7 pairs of the nova series including this pair, People drop crap off at my place all the time and realistic seems to have been popular in my town
I cant say ive heard a Realistic speaker that sounded good myself, but ive been spoiled buy buying JBL and B&W stuff lol They ARE however awesome quality for the price back then and even still better quality then most new stuff under 200 bucks
Just bought a pair of these. I put tweeters in them myself as well. They sound great!!
Cool pick from the store and seems to sound good too.
I have 4 JAMO Cornet 65III 120 watt, 6 ohm each speakers, but could never find any info on them... They are super nice though
do you remember if the yellow wire goes to the positive or negative terminal of the 8 inch speaker?
Unfortunately I do not. If you have a multimeter with a continuity test range, you can backtrace the wiring and find out for sure.
Thanks for the post. I have four of those that I bought brand new in 75. Going to rebuild them all, and have been looking for a good source for parts. They are very well made.
Those cabinets aren't much different from my old MC-1201's. I experimented with them for years,
eventually replacing all of the drivers and crossovers with new ones from Radio Shack until I was happy.
@uxwbill It says on the back that they were made in denmark, but i have no idea where they were bought or anything, I found them in my house when we moved in. I will check out that forum thought, thanks
those were made in Japan or Korea, the new woofers are Danish
@@manFromPeterborough Hi from 9 years ago!
awesome video i cant wait to see ur next retro computer video
How do most tweeters connect? Are there clips or is there any soldering involved? I'm about to replace the tweeter in a Polk Audio CSi3 center speaker.
i got the same model screen as you got on the floor next to the bed :D
I tried the light timer on a radio once and it ended up blowing the radio or they both blew so I wasn't sure about the light timer thing. Did I do something wrong?
Any good links to some good places to find new replacement speakers?
Parts Express is a good place to start. They have individual speaker drivers and complete speaker systems for any budget. If you want to repair your existing speakers with an exact part...sometimes you can get lucky on eBay.
I just got a pair of RS Nova 5 speakers from an antique store for $15. They look just like yours. I hooked them up to an old Panasonic amp/receiver/record player unit and they sound good.
I have a pair of Boston speakers too.
They have way more bass. I use a Fisher amp for those though. Maybe that’s why...
Thank you for a very interesting video. Are those solid wood cabinets? What kind are they?
The question i have is I used to own a optimus sta-795 an i was impressed. I would like to know if anyone knows the power output on that particular model.
Good video. Enjoyed thoroughly
Is the tweeter the driver. What's meant by speaker drivers ?
Speaker drivers are the speakers themselves. If you need a better explanation, search the internet.
keep an eye out for realistic speakers bose made the for several years ...u me pass up one hell of a speaker..grt vid
i had a pair of singer speakers simular to those and i had to replace the tweters in them nice little speaker for singer wish i still had them.i might look for some of those to go with my little singer record player. i have the singer he 925 record player .
@uxwbill Excellent. I think the Polk CSi3 is a fairly decent speaker. Looking forward to hopefully not having to solder anything, heh.
Thanks.
can you make a video on the audio timer?
@uxwbill by any chance would you know anyone that might have one for sale. i found one but he didn't want to ship it so i didn't get it.
how's the bass ? is it close to what we find today?
shiraq07, NO
They might not play down to 20-30hz like my technics do but they sound pretty good for their age
haha yea there smaller 8-12 inch stuff is nicer, I sold a pair of the "Famous" Mach Ones last year Im shocked anyone wanted them
Hey, you should make an intro for your video's. Something with classical music and you fixing various electronics. It would be fun! :)
Also, nice speakers and fix. :)
Terry Stafford, the English sounding Elvis. You must be 30 something, that makes two of us. Anyways, got a buzz in my pc left channel from accidentally having my volume up too high, and landing on some YT site that had their music way high. Will check out the Dayton Loudspeaker Company. Thank you.
What happened i miss you :'(
😲😯😮💖👍‼️
Your doing this on your bed D:!
I do my electronics on the bed too, nowhere else to work on them and the bed is ideal for turntable work where the TT needs to be bottom up
