I'm curious about the power and SPL rating differences between the UCS1 and UCS1P.

The UCS1 has a program power of 1000 watts with an SPL rating of 132db.  The UCS1P has a program power of 1500 watts with the same SPL rating of 132db.

Is this correct?  What is the additional 500 watts used for, if not to push out more sound?

Apples to Oranges.

One is the driver - speaker rating; the other the internal amp ratings.

I am pretty sure Tony has hit it on the head.

From what I have been told (from Yorkville), the UCS1 and UCS1P are using the same driver.

[Phillip Mispagel]

Yep, thank you for the info.

FWIW the two models do not use the same driver, the powered version has a larger voice coil.  While they will sound similar as far as I am aware, they have made other changes to the powered version and it is not directly compatible with the passive version.

I am just reporting what Yorkville told me about the drivers...  

Quote:

The woofer used in the Unity subs has a ferrite magnet (P/N: 7447).

The U15 and U15P use the same HF and MF drivers.  However the LFs are different, the U15 uses an 18Sound woofer and the U15P uses a B&C woofer.

I was asking about ordering some replacement drivers for my Unities and I asked if there was a difference in the drivers between the powered and non-powered speakers.  I was going to order spares to have on the shelf just incase something happened.

Conversation was dated: March 2008

Things may have changed since then.  Does anyone have a parts order catalog to confirm the part numbers are the same or different.

Right now, I am debating about buying 2 more UCS1 and a Pro9200/PL380 amp OR selling the 2 UCS1 and buying 4 UCS1Ps.

The UCS1 and UCS1P use the exact same driver.

look at the yorkville web site, by the specs they show they use a different driver, so which is it a 3" v/c or a 4" v/c..
Not to bash yorkville but i ordered 4 UCS1P's, (1) out of the box had limiter issues, got replacement and then another failed again with limiter issue.. we are sending all 4 back as customer has no faith and wants something else, what I will say is they sounded great, very impressive, if they get the limiter issue fixed they are a great value and have gobs of output...R

The voice coil is 3".

What was the issue with the limiter?
