Just wondering if the 4Pi professional series with JBL drivers would really be 100db efficient.

I thought JBL 2226 woofer is only 97db and the overall sensitivity will be that of the least efficient part of the system.

I'm going to go out on a limb here and say that the sensitivity is likely a moot point in your case at least with this particular driver combo. I say that judging from your nic that you will be running a 45 watt push pull tube amp. My experience with 4 Pi's is that the more power on tap the better they sound. Not that they sound bad with small amps, a 2 watt SET amp sounded great in the mid range and top end when we demoed it, but the bottom end was very lacking. I normally run my 4Pi's with a 75 watt crown SS amp. It sounds great, good bass, very detailed but nothing like the 300 watt Luxman that I've started using again....it literally will beat you up if you want it to, the 2226H really seems to need some power to get the best out of it, at least in my experience so far.

(Actually , the set amp midrange and top-end was incredible, clear, detailed and yet it took the edge off so so recording with out loosing anything....makes ya kinda think....shhhhh don't say it Wayne will kick me off....)

There are two versions of this model, one having a 2226 and the other having a 2227. The model containing a 2226 is rated at 97dB and the one containing a 2227 is rated at 100dB.

Hi all,
Do I hear that wonderful combination of SET's and JBL 2226's again, They may not hit extreme SPL's, but sound damn good to where you don't miss what they don't do, just got to love what they do when they perform like those of us who do know have experienced!
Regards, Ron

Thanks - I am thinking about the 4Pi and just want to make sure that they are 100db. Sounds like I will have to use the JBL 2227 woofers.

So what type of amp are you going to drive the 4 Pi's with?

Kelly,

I have quite a few amps: a single ended 45, a single ended 10 - these two I use the most. In the closet are: a single ended 300b, a Pilot 232, a Scott 222C, an Eico HF-86. I am thinking about 4Pi with the JBL 2227. I think every 3db count when it come to single ended.
