I have multiple speakers and one amp and want to quickly be able to plug in different speakers when I wanna listen to them using the one power amp . What are some connectors I could use to do this ? My amp doesn't have the banana connector .

Why not use a high quality selector?

Why not use a high quality selector? How much would one cost ? I could get connectors for probably under $20 . |

It would cost more, depending on quality, but a good passive switcher is much more convenient. Not to mention - consider the wear and tear on both ports and connectors.

The Coleman Audio LS3 Line Selector looks cool . Seems like you could hit all 3 switches and listen to all 3 pairs of speakers simultaneously off 1 power amp . Is that possible ? Those are cool boxes . What about ebay ? Any cheaper products on ebay ? |

Both of those Niles Audio units should be very good quality.

What's there is what's there and my psychic ability is on the fritz again. I wouldn't be so concerned about cheapnes - this is not an area you want to cheap out. |

I rack-mounted this Niles Audio unit, as well as built the Sound Skulptor one.

I got it in the mail , it works great ! I think I paid $26 shipped . It has wood sides , they aren't vinyl . Sure beats paying $100 or more .

I also need this functionality to be able to switch between our Sonus Faber and Cabasse systems. Nice find if it works as advertised and quality is ok. |

I also need this functionality to be able to switch between our Sonus Faber and Cabasse systems. Nice find if it works as advertised and quality is ok. It works as advertised and the sound quality is definitely ok . The connector on the back is a little cheap but other than that it sounds good to me . I haven't done an A/B comparison with it in and out of the chain . The connector is cheap so once I got everything set I didn't wanna mess with it too much any more . I have NS10's and infinity primus 360 speakers . The NS10's are not enjoyable to listen to !! Especially when you switch over to the infinity speakers you can really hear it ! I really like these infinity speakers and they are REALLY cheap . You can have pairs of speakers run at the same time by selecting both switches . Is this hard on the amp ? Can it damage the amp ? I would think if it did damage the amp then they wouldn't design it to do this . My review is its cheap !! So pick one up and give it a try . I'm happy with it . |

Haha, sure, i just thought it would be nice to know it it falls into parts after 2 weeks, scratches after 20x switch, you know what i mean? For this price noone expects wonders.
Or the Spanish Inquisition.

Au contraire... just because they don't avoid switching more speakers the same time does not mean this is automatically safe. If you can parallel multiple speaker pairs, it is not - by design. Period. Of course the user is the one who is responsible for getting this right...sooooo.... I assume they are switched in parallel, because this just needs the cheapest switches. Now, the impedance get lower with speakers in parallel. In series, speakers just get more quiet, no problem, as the impedance rises. But lower impedance means more load on the amp. And yes, in unfortunate combination, this can get a problem. If the amp is already working hard e.g. switching a second pair of the same speakers in parallel halfes the impedance (the formula for parallel impedances is Ω = ΩA × ΩB / (ΩA + ΩB) with ΩA and ΩB beeing the impedances of the paralleled speakers). (OK, this is kept simple, because they also have an inductivity....but in this case it's pretty ok to get a rough picture of what is happening...) Too low impedance results in the following: First, the sound gets weak and poor. Lower the impedance further and the output transistors get hot because there is too much current running. When the amp comes to a critical limit, the output transistors heat up the way that the amp should be shut down. Much distortion happening then.... Worst case is the amp does not properly it's thermal safety shut down and you can damage both, amp due to overheating AND speakers due to DC / melting speaker coils. Molten speaker coils easily results in a short. For this reason amps should always have a short protection circuitry to avoid the worst. BUT of course they only should, but actually some have not. Due to cost cut reasons or whatever. Then you damage both in worst case, amp and speakers. Unfortunately i already saw such mess, and was happy it was not my stuff... So if not sure your amp can handle the min. resulting impedance, don't parallel speakers. Simply don't. And you can not rely on what is written on the speakers. Most speakers are not 4 or 8 Ohm, but all over the place, and impedance also is not constant when the speaker works. And yes, if things get ugly it gets expensive in the worst case.... You can have pairs of speakers run at the same time by selecting both switches . Is this hard on the amp ? Can it damage the amp ? I would think if it did damage the amp then they wouldn't design it to do this . |

Btw, yes, Infinity speakers are dirt cheap nowadays and sound good if they are ok. But who said the NS10 sound, ehm, good?
I have also a pair of small old Cabasse speakers that sound excellent as nearfielders - on a 3,5k amp. Bought them for 200 Euros. When we fed it with a RM converter and an excellent amp, mouth stood open. MUCH better than ever expected. Great stereo field/room. Nobody wants that old speakers. So you can make real bargains from time to time... Add a sub and you can get something really good sounding...
