I'm about ready to recap my 7Bs with Dayton 15uF poly caps and these devils are HUGE compared to what is in there now. Will there be a problem with anchoring the cap to the back of the cab with a shot of hot melt glue, or a piece of foam mounting tape? I'm new at this and don't want to get off to a bad start. Thanks.
Realistic Nova 7B Crossover
- Thread starter DTiberius
- Start date
Hi folks. this will be my 1st post here at AK.
Hopefully I don't get flamed for bumping an old thread, but let me know if that's not something that's welcome.
I'm not totally new to the audio sport, I've been involved with pro audio over the years and have owned a few "vintage" audio pieces...Norman Laboratories model 7's...some klipsch something's...cant remember.
Anyway, I just bought a pair of Realistic Nova 7B's hence why I posted in this thread....
One of them is working great and sounds better than I expected.
The other...both tweeters sound good, the woofer is working but isn't getting the low end. In other words I think I have a crossover issue. Seems as though all the speakers in the cabinet are trying to play the same thing.
I've read a bit about the caps etc. Is this my problem?
How can I fix this crossover and send the woofer its rightful low end signal?
Anyone have any recommendations? Thanks

The crossover should not affect any output to the woofer. I would check the connections and clean the switches on the back of the speakers with electrical contact cleaner. You could try swapping the woofers between the cabinets and see if the problem follows the speaker or the cabinet. Let us know your results so we can be of further help.

As an aside, the woofers turn up fairly frequently on eBay, so replacement, if necessary isn't too difficult. Love mine.
Ok..i put the working woofer into the other box and it was working fine there too.
So....i assume I have a blown woofer. And will need repair or replace.
Question is ....is this woofer replaceable?
If not and I can only get close...then perhaps someone here can suggest sonthing.
The frame of the woofer is unique though....not round..kinda has 4 curved sides.

I assume you tried the "bad" woofer in the opposite box and it still did not work. If so, the woofer is bad. As was suggested, pick one up from eBay. The Realistic Optimus-1b is the same speaker with a different grill so one of those would work too. Be careful, there is a Nova 7/Optimus 1 speaker that uses different drivers. Make sure you get the "b" model.
Edit. I just looked on eBay and there is a pair of Optimus 1b woofers and a single Nova 7b as well as a couple pair.

At ten watts power handling. Take that up to about 700hz and they'll be far less delicate.

Congrats. I've already said how much I enjoy mine. Daily listening at work.
