Difference between 1132 and 1133 drivers

Recommended Posts

As the title says what exactly is the difference. Is it the diaphragm only or are there other differences?

Since we don't sell them as raw drivers we currently don't have spec sheets on them. On the Kt series the need to add a snout to take the driver to a 1.4" or 2" exit has been removed. The driver front plate exits at 2". The phase plug for the 1132 is different than the phase plug of the 1133. The KT diap has a few tweaks but should work.

Well the answer is the 1132 has a big rubber gasket cover thingy around the magnet and the 1133 does not.

I think the 1132 can be viewed as a driver who's intent is to be in a 2-way system and the 1133 is intended to be in a 3-way system.

 

That's my understanding.

That's right and my question was how to tell unmarked drivers from each other.

Well, I didn't read your question, I just wanted to show you how smart I wasn't.

 

:tongue:

 

Do I have another voice in the back of my head (typically drowned out by the other voices in my head)....  that one has a phase plug?  (implying the other might not)

 

I shrug my shoulders.  Too many voices.

 

Anyone think to ask @Chief bonehead??  I understand he might have an inside track on the differences.

He's a busy guy and I don't want to bother him with questions until I have spent some time trying to find an answer first. As it turns out the answer was simple to see when I placed some side by side with an old 1132 I had.

The 1132 is the American version. The 1132 A is the Canadian version A? LOL.

 

I have had both the snout version and the non snout version of the 1133 which rolls off at about 5 Khz., so it's defininitely 3 way. Snout and non snout were BOTH a 2" exit.

 

I'm pretty sure they use the same Titanium Diaphragm, magnet, etc. but use different phase plugs to shift the band upwards for the 1132 for 2 way with shelving.

Yes for sure but my question was how to visually identify them since the drivers I got recently had all ID and serial numbers pulled off them. The visual clue is the rubber thing around the outside of the magnet which denotes the 1132.
