Best subwoofer cable ?

[Kingnoob]

I would not try and straighten the pin. It may break off.

I think you have things correct. With the switch set to "Crossover" the sub should use the crossover FREQ control. The FREQ control is used when you have a full range signal coming in. Since you have an AVR with subwoofer management, the AVR handles the crossover point for you, so having the FREQ control turned up all the way is correct. If the FREQ control was turned down, you could potentially filter out bass below the AVR's setting.

Don't worry about the brand! If 25 foot is the length you need, copy & paste the text for the one below- it's $26.99 and has a right angle plug on one end and lifetme warranty, but that doesn't cover physical damage.

doesn’t seem they go on sale , not lately .
Looks about the same as the old Mediabrige brand that’s now gone or defunct ? Maybe better ?



Both brands LIMITED LIFETIME WARRANTY] Includes a Limited Lifetime Warranty, the fosi says you gotta register for it???

 

[Kingnoob]

Trying to decide if I should replace the bent cable or wait until it breaks ?

 

[Eppie]

That's not a particularly tight bend and I don't see the cable pushed up against the wall putting pressure on the connector. If you don't move the sub around then it should be fine.

Assuming it is a multi-stranded core I wouldn't worry about that level of bend at all. Solid core wires however have a "minimum bend radius" limitation which needs to be heeded or the core can snap like a stick.

Not so much with audio but with some transmission technologies such as RF there is also a "minimum bend radius" limitation not due to a fear the core will snap but because the wire turns into an oval cross section (instead of a cylinder) and this can compromise its impedance.

People using 75-ohm coax such as RG6 for antenna feeds run into this problem. I think the very fact that we even call the cable "75-ohm" shows maintaining that is critical.

Media Bridge brand can’t find them anymore must be defunct??

Your center pin does look a little bent (and there's lots of carpet fibers that obviously need to be wiped/cleaned off for good contact) but with sub wires they basically either work or don't work. There's pretty much never any in-between status you need to be worried about.

Think it’s better than a bland no name rca cable ? The bent one ? Here’s fosi vs media

"Subwoofer wires" are simply normal RCA audio wires that aren't being tasked with the full audio range bandwidth; just the deep bass by itself. Any functioning RCA wire will do fine.

Marketers' descriptions of their RCA wires having "differing sound qualities" (hence some being more adept at being for subwoofers) is 99.99% bullsh*t.

We used to move video signals around via RCA connections too and here there were other (but easy to meet) considerations, but hardly anyone still uses them for that anymore.

yeah I guess swapping a sub cable with a bend for RCA without one would not make much sense .
RCA aparently can’t do 1080 or 4k ? video? I have issues with my HDMI’s don’t know if it’s because the TVs are old or need new cables . Some of my cables are new ish . Roku jumps to the wrong input

In modern times 1080p and higher "needs" HDMI but only because Hollywood didn't like that analog video wires, RCA component (red, green, and blue colored jacks), could carry UNPROTECTED (HENCE EASILY COPIED) HD video, so they pushed for the adoption of harder to copy digital signals using "security keys" (I forget their exact term for this security scheme at the moment) through HDMI, and they effectively won that battle.

I see so pirates killed RCA?
Yeah I thought RCA component (red, green, and blue colored jacks) could do 720p or even higher but a HDMI can carry both audio & video . It’s odd a few of mine say Ethernet also but you can plug it into a modem/router ???

The Analog Sunset

Blu-ray players are changing — and your HDTV might not like it. However, if your TV has an HDMI input, and it’s HDCP-compliant, you don’t need to read any further. You have nothing to worry about. This article doesn’t concern you. Put down the magazine and do something else just as constructive...

All communications cabling has a minimum bend radius- it's supposed to be used so installers won't lay bundles and groups of cables over sharp metal and wooden edges. It's not that the solid center conductor will snap, it's because it wants to remain straight and by bending the whole assembly, the dielectric will be compressed and that causes problems because the conductor is supposed to be centered, not close to the shield. Category cable has a minimum bend radius, as well as maximum pull limit which, for Cat5e, is 25 pounds.

Typical tule of thumb for bend radius- 4x the diameter.

Not the pirates themselves, it was Hollyweird's fear that people will copy their precious, crappy movies and worse, they seemed to think that pirates made one copy at a time, in real time, player to recorder.

That shows total ignorance- if someone wants to make money by copying media, they'll save it to a computer and use multiple banks of burners.

Component can send 1080p, reliably and audio with the stereo pair or multi-channel with an optical or S/PDIF.

Personally, I see the 'analog sunset' as vandalism. NOBODY bought a high quality DVD player with the expectation that it would only transmit low res video, especially when it worked for high res before the sunset date. CONGRESS strikes again. I don't know how much money changed hands, but they're all dirty in this.

Ethernet cables are used for IT networks: to the modem, from modem to the router, between router and switches and other devices that need to communicate on the network.

it's usually due to repeated bending in one area. In the 50+ years I have handled/installed Coax, I have never seen it just break like a stick. That AI answer is also very vague- might be better to go to a manufacturer's site and look for their recommendations.

 

[m. zillch]

In the 50+ years I have handled/installed Coax, I have never seen it just break like a stick.

You wouldn't see anything because it is internal and concealed from view plus such compromised cords sometimes seem to continue to sort of work (although with a higher signal loss) because the two cracked core sections are sometimes still touching each other, at least partly, tip to tip. Plus if you are already of the mind RG6 should not be bent beyond its minimum bend radius for only other reasons such as ovaling and dielectric compression I depicted earlier in my supplied image . . .

. . . then you wouldn't encounter such wires with compromised cores in the first place.

Additionally I'd think using RG6 outside in potentially freezing conditions would make the core more delicate/brittle but that's just a guess.

It's not difficult to see that the cable isn't round and in those 50+ years, I have seen plenty that worked and tested fine, but had been coiled tightly in order to be stuffed into junction boxes, laid with so many other cables that the ones at the bottom of the bundle were under 20 lb of dead weight. Once the weight was lifted off and they were supported better, they were fine, but the rough-in installers needed a bit of training.

Cold temperature for us means nothing to metal, even thin wire. Plastic, OTOH, doesn't bend as well, especially if it's the same kind as what's used on power cords that never straighten completely and I'm sure you have seen those on all kinds of powered tools and some appliances. THAT makes a difference, but good cables are tested WRT temperature and other environmental extremes.

Since you linked to a Chinbese company, I'll comment on the stiff wires and cables- the majority of the ones that were extremely stiff were made in China. Corded drills, polishers, auto battery chargers and yes, coax & Category cable are all affected. Some are flexible, but many are not.

What cable are you referring to that can make contact from tip to tip? Coax has one center conductor and foil/braided wire shielding. Shielded twisted pair isn't the same and is usually smaller diameter.
