Speaker Connector Choices

We are proud to offer you some connector choices when configuring your speakers.  Some of you have style considerations in mind.  Others want bi-wire capabilities (What's Bi-Wire?).  Whatever your reason, we currently offer four different choices.  If you have specific connectors in mind that you would like to see offered, please let us know.  If there is enough interest and we can offer in an economical fashion we will certainly try to do so.


Here is a quick guide on the choices available to you:

  • Satin Nickel Binding Posts:  These large posts are solid brass with an attractive Satin Nickel finish. They accept bare wire up to 10 gauge, spade or banana plugs.  The head diameter is 11/16" (17.46mm).    We mount them into the bespoke Ostinato backing plate.  A high quality choice - pick these if you prefer a very clean look or just don't have any preference.  No additional charge for this selection.
  • Bi-Wire Satin Nickel Binding Posts:  Two sets per speaker of the Satin Nickel posts.  The top pair is wired to the tweeter cross-over network and the bottom pair to the mid-range/woofer network(s).  They can be bridged with a jumper bar for when you want to use one pair of wires/amp. 



  • SpeakOn Twist Lock:  Some of us at Ostinato prefer these.  Coming from the pro audio world (e.g. recording studio), these connectors provide touch free contact, are simple to connect and disconnect and look (and are) professional.  We use the fully metal versions for their robustness and aesthetics.  The down-side is that you need to make or buy cables with SpeakOn connectors on one end.  Ostinato offers these and there are certainly other online sources just a google search away.   No additional charge for this selection.





  • Bi-Wire SpeakOn Twist Lock:  This choice is a bit of a purple unicorn.  You will still have some uniqueness with the SpeakOn connection, but to fully impress your friends you will be forced to actually tell them you are bi-wiring (or bi-amping) as it will not be obvious to the eye.  Seriously, some of us at Ostinato run this way with our own setups.  Warnings, provisos and a few quid pro quos - Please note that with this connector you must have a cable with 2 pair (4 wire) per speaker.  The cable must also have whatever termination on the other end fits your amplifier configuration(s).  We are happy to build this for you.  You can also build yourself if so inclined.  This may be a harder configuration to find on the open market.

What is Bi-Wire (and Bi-Amping)?

Bi-Wiring is when you connect two pair of cables to each speaker.  At the speaker end of the cables, one pair of conductors connect to the tweeter and mid-range (for 3 way speakers) cross-over network(s) and the second pair to the woofer networks.  At the amplifier end you can connect both pair to one amplifier (Bi-Wire), or to separate amplifiers (Bi-Amp).  The reason for Bi-Wiring is that by doubling the amount of cabling you are lowering the electrical resistance that the musical signal crosses.  With Bi-Amping, you can use different types of amplifiers for each part of the speaker (e.g. Tube amp to your tweeters/mid).  

Will any of this make my music sound better?  Well, just like with Capacitor selection in the cross-overs, this can be a contentious topic.  As a Company we are not picking sides.  Some of us think it adds value and some of us don't.  We don't judge - we just provide you the choice.
