Audio sockets/wiring yet again

Nov 16, 2014 39 Replies

After a long delay I am finally getting rolling on replacing the lounge floor, including running speaker cable underneath to the point where the speakers are.



I am still struggling with how to make a permanent cabling solution which also allows the removal and replacement of the speakers for short or long periods.



As far as I can see the best thing is to have connectors in the floor. However making them unobtrusive is the challenge. Most recessed solutions seem to rely on a flip up cover for when the speaker is in use. This is too obtrusive as the speakers will be wired in for extended periods.



The smallest footprint seems to be RCA female sockets in the floor. I am struggling to find a discreet solution - panel mount sockets look good but they are proud of the floor. If they are recessed, of course, they are dust traps.



Anyway, look to offer quite a good compromise between profile and a discreet look when not in use. They are a bit expensive, though, at over £3 a pop. I anticipate needing: two for each rear surround speaker (4 total) four for each main front speaker for bi-wire (8 total) In the great scheme of things £36-£40 isn't that much but these seem a bit more expensive than other RCA panel mounts (is this because the supplier is RS?).



I don't have to be as discreet for the other end as all the wiring will be hidden behind the AV equipment.



So can anyone suggest a similar socket which is a little cheaper?

I've just ordered a batch of these:

Not arrived yet (3 weeks delivery from China) so can't tell you about the quality. They look neat to me though, as they are not only flush-fitting, but the binding posts are recessed within the fitting too.

Thanks - I'm trying to avoid putting a 1 gang box in the floor because that seems far more intrusive than just fitting RCA sockets directly into the wood.

Memo to self - check the maximum thickness of panel that the sockets can fit into!

So it does have to be in the floor though? (mine will be in the wall like a 13A soccket, with the cables chased into the plaster

Box in the wall is the last resort and I really, really don't want to do it. The room is newly plastered and I don't want to start hacking it about already. I am now considering putting RCA sockets in the skirting board instead of the floor, but again it would be a "panel mount" to minimise the impact.

I'd not use RCA (aka phono) for speakers, they probably have high enough current rating but it'll far to easy misconnect an amplifier output to an input... Personally I'd use female XLR's with dust cover, still a bit proud but not a lot. But fail badly on the cheap part of your spec.

I'd consider putting 4mm banana sockets into the skirting, such that the fr ont of the skt is flush with the front of the skirting.

If you solder, another possible is simply a flush wire loop in the floorboa rd. Drill 2mm holes down thru the board, and slice out a 2mm groove between them. Loop cable through, solder behind. Cheap, flush, minimal visual impa ct, no dust trap. Place them close to the wall to avoid damage.

quarter inch jack sockets?

Three pound a pop is pretty low cost,,

For myself,, why go to the trouble of discrete wiring and then skimp on the connectors,,

i used to have beefy wires for audio, spent a long time playing about with audio note silver solder and stuff like that,,

I was surprised to find audio note silver spades were so cheap.

I imagine you are on about fairly light wires for surround sound.. Its hard to beat your price cept by drilling a hole and twiddling the wires together,, solder them together ,, is there a carpet..?

You can get tiny little dolls house connectors,, Simple fact is that speakers come with wires,, hard to avoid really,, I like chunky wires, though simple thirteen amp cable will do..

Some audiofile floor connectors are a hunnerper pop..

but well .. are these worth a look,,for your needs.

If you want to mount sockets on the floor I'd think it was important to use sockets that won't be damaged if they are knocked or kicked. How about flush DIN sockets? They are robust and have a very low profile.

That depends on the system. The "5" channels of 5.1 are full range, full power channels, so in a decent system you ought to be looking at

100W each. This needs a decent bit of copper between the amp and speakers, 2.5 mm^2 plus, "bell wire" doesn't cut it. The .1 is band limited, rolls off above around 100 Hz, but as it's the LFE (Low Frequency Effects) also need a fair bit of omph. Also note that the only signal in the LFE are the effects bangs, booms, earthquake simulation... etc.

Having said that most domestic "5.1" systems use tiddly little satelite speakers for the 5 and cross over with the single low frequency speaker at maybe 250 Hz. As the tiddly speakers don't need to shift great amounts of air they can be relatively low power so using "bell wire" is less of a problem.

Aye, making sure there is a good low impedance path between speakers and amp is one way of cheaply improving a system, particulary the LF.

Oh, I dunno, these are pretty cheap:

Ok, the latch is a little proud but it could be removed if required.

Neither is suitable imho

Goan and beat it for three quid..

I would not choose them either,,

the poster says he wants cheap as chips or invisible wiring,,

///

I have cheap creative labs speakers connected to my pc by little more than bell wire,, with Xonar d2 audio card..

wont knock your pants off but sounds pretty good to me,,

Cept, tube dont always let me play without interruptions..

And decent Neutrik and Amphenol ones aren't much more than that, and are around the most bomb proof connectors around;)..

Seems a waste of a very good card on speakers like that;!..

76 strand cable is the product to consider:

(Not recommending the source, just showing the cable.)

A lot of people seem to use Banana sockets, so you can do the phasing etc. There used to be some that mounted without a front lip, but I've not seen them in years. You needed a recessed hole for the nut. Brian
