The Classic / Model I / Model II output for the B1s is
* 125 Watts into 8 ohms (single B1)
* 250 Watts into 4 ohms (two B1s)


Hilmar-at-Bose tells us:

If you have two sound source that are
*125 Watts into 8 ohms (single B1)
* relatively small
*250 Watts into 4 ohms (two B1s)
* not driven very hard
 
* you look only at relatively low frequencies
Hilmar-at-Bose tells us:
Then you get 6dB more sound pressure level (SPL) from 2 as compared to one.

Our B1 is a good example for that:  
Our B1 is a good example for that:  
* 2 B1s give 6 dB more than one.  
 
* You gain 3 dB by simple doubling the electrical power (250 Watt for two, 125 Watt for one).  
*2 B1s give 6 dB more than one.  
* The other 3 dB are gained by doubling of acoustic volume, cone area and close coupling between the speakers.

To get the same SPL (as 2 B1s) from a single B1 you would actually have to hit it with four times the power (500 Watt).

== Keep the B1s Together ==
 
== Keep the B1s Together ==
 
If you have more than one B1 playing the same sound source (instrument), keep the B1s together. You should get as much as 3 dB more than if you have them separated. This is due to acoustic coupling. This also avoids creating [[Nulls]]. You can stack them or have them side-by-side but you want to keep them together. For more comprehensive discussion about this see [[{{PAGENAME}}#Arranging_and_Placing_the_B1s|Arranging and Placing the B1s]] (below).

== Rotate the Logos ==
You can rotate the Bose logo so it is parallel to the floor even if you have turned the B1 on its side. Chuck-at-Bose said, "... Maybe it's my kung fu grip, but I've had good luck with carefully pinching the logo and pulling at these points, then rotating 90 degrees:"

Be very careful with the fine ends of the logo because they can be easily broken off. You may even try to pull up in the middle with your fingernails on the edge instead of near the ends.

Pull the logo straight out about ½ inch before you attempt to turn it. It is spring loaded, and the rear post is square. You have to clear the post (about ½ inch before you can turn it).

== How Low does the B1 Go? ==
The short answer: 40 Hz.
But what about instruments that go lower than that, for example a five string Bass. A much better answer comes from Hilmar-at-Bose in [[Bass Frequencies]]

:It's a relatively small woofer and it's good up to 3.5 kHz or thereabouts, which is plenty for many bass applications. It's not quite as smooth in the mid range as I would like for a "full range" speaker.


;Question — Would that be because of the cabinet design or the speakers?

;Question — Would that be because of the cabinet design or the speakers?  
:little of both actually but mostly it's cabinet design. The box is optimized to provide very good low bass and we just didn't want to compromise to dial in the higher resonances, since we were not planning on using the box at these frequencies.

== Port Orientation  ==


"Theoretically, port-side-up may give a tiny bit better aligned floor reflection but in practice, the difference is so small that it isn't worth bothering with. However, I would still advise when you stack multiple B1s keep them all in the same orientation." - Hilmar-at-Bose <ref>[http://bose.infopop.cc/eve/forums/a/tpc/f/3976055944/m/9791009151/r/9791009151#9791009151 B1 Port Orientation: Hilmar's  post in the Bose® Musicians Community Message Boards]</ref>


== Port Orientation ==
When I read this, I had to go and look very closely to find the port. It's easier to figure out that when the B1 is on it's side, port side up is same as (on the back) connection panel down.

The Bose B1 requires a NL4 connector with all 4 pins connected (that's why we call it 4-wire cable). Unfortunately, the Speakon connector comes in three different flavors, NL2 (2-pins), NL4 (4 pins), and NL8 (8-pins). Most salespeople are not aware of the differences.

If you call Mark and tell him you want the cable for the Bose B1, you will get one that is made to our specifications. You can also any custom length cable at a very reasonable price.

I've seen it mentioned here a few times - those wriggly uncooperative B1 leads when they're new, and no posts about how to cure the problem.

Here's 3 suggestions:
<br>


1. Taking care to hold the speakon connectors, soak the rest of the cable into a bowl of very warm/hot (not boiling) water. DO NOT GET WATER INSIDE THE SPEAKON PLUGS. This will soften the cable up, lie the cable out flat and straight to dry. This will give it a "new memory" of sorts and be easier to maintain in the future.

2. Wrap the cable or lie it flat and straight and leave it on the footpath or driveway in the sun. Shouldn't take long.

3. Leave them wrapped in your car/van on a hot summer day. This is usually how I unintentionally fix all of my cable messes.
