The N3S Kit

No longer available due to no more availability of the BG Neo 3 pdr with deep back cups.


The N3S kit is a small sealed box version the the floor standing N3 transmission line model. It is designed to be used as a matching center channel, but can also be used as left or right main speakers. The sealed box design allows it to be placed closer to rear walls or used in entertainment systems with placement limitations. 

The price listed is for a single kit (one speaker). So if a pair of these are needed then you will need to specify two of them on your order. The only difference in ordering two of the N3S kits verses an N3 kit is that the N3 kit comes with floor spikes. Then the box design that you use becomes the only real difference. The kit itself is the same. 

The N3S kit uses a pair of the M-130/16 woofers and the OEM version Neo 3 pdr. This deep back cup version is not available through any other sources. The kit comes with high purity Copper inductors and high quality poly caps from Erse. Resistors are non-inductive Lynk's. Internal wire is a high purity OFC. The tweeter circuit includes Gen.2 Sonicap by-pass caps as well. 

There are various options available to allow one to take the performance up several levels depending on ones budget. Upgrade options include highly recommended Sonicaps and Mills resistors to take clarity and detail levels up a notch. 

We now offer the new patent pending Electra Tube Connectors as the standard speaker wire connectors for all of our upper level kits as they are superior to all current binding posts. These have a $59 a set retail value. The standard internal wire is a high purity solid core 16 gauge with a polyethylene jacket.


The N3S kit is fairly easy to build. The kit comes with everything you'll need minus assembly tools and enclosures. The networks do require assembly and basic soldering skills are necessary. 

The N3S (sealed box) allows for a gradual low frequency roll off with a -3db down point of (in room) that will be in mid to low 60's. 

This speaker has good sensitivity and is an easy 8 ohm load. It is ideal only for small to medium sized rooms and can hit fairly high SPL levels with no problems.

One sheet of No Rez is highly recommended. Order it here.
