Remember that most theatres have between 6 and 16 of these dividing the power between them. One theatre I worked at had 36 of these on the walls of one auditorium. And even if the speaker can handle 200 watts you can still hook up to a 1,000 watt amp, you just can't feed it 1,000 watts continuously.

As to the naming schemes...NO the "8" and "3" have nothing to do with the typical quantity. The 8000 series predates JBL offering an Offical surround speaker. Some used their 8000 series of foreground speakers, some used utility speakers like the 4612.

As to their driver convention. The 2000 series is going to be a bass driver. The 2226 is the evolution of the 2220 drivers. As in the 2226 replaced the 2225.

The 2226 is a bad-ass of a driver, it will handle 600 watts of continious pink noise. It has a rather cleaver cooling system too to minimize power compression

The 2035 is the lookalike driver to the 2226 but it only has a 3" voice coil (the 2226 has a 4"). It handles about half the power too. It was brought about to be loaded into cabinets that will have passive crossovers (first in the JBL 4670D and 4675C). Since the passive crossovers could not handle the 1200 watts the 2226 could handle, this allowed JBL to have a lower cost driver since the 2035 can adequately handle the lower powered passive systems. I don't know if it is the rooms they were in but I have had much better success with the 2226. For the most part, my systems are bi-amped.

Another difference is that the 2226 is available as a raw driver, the 2035 is not...it is only sold in finished systems.

As to the power handling...the continious pink noise is set up by the AES and is a standard in terms of the bandwith of the pink noise and the duration. Continious program is merely double that power (or 3dB more). "Peak" power is often double continious program.

So in the case of the 2226, you have 600 continious pink noise, 1200 watts of continous program and 2400 watts peak. Is that a bad-ass or what?

The JBL 2242 is even more of a humdinger...it's numbers are 800/1600/3200. However, I generally disregard the peak power and in the case of subwoofers, only look at continious pink noise.

For home theatre use, I must strongly recommend a Canadian line of speakers called Paradigm. When I built my home theatre last summer I must have researched and auditioned about 30 diffrent Home Theatre setups, and after the smoke cleared, the only ones left worth buying were the Paradigms. While I can't say I compared JBL cinema surrounds in that mix (and I'd love to do so if the opportunity ever presents itself), I can say that these are the most natural sounding and clear speakers I've ever used.

I went with the Monitor series--Monitor 7s for L & R, CC370 for a shielded centre (yes, the shielding is most definitely needed!), two ADP370s for surrounds (bipolar) and a PDR-10 sub. I would up using my old centre-channel speaker for the surround-back channel. Everything all said and done, I paid about $1600 Canadian. I actually drove to Canada and bought them, then got the taxes back at the border. Even with hotel bills and gas, etc, I came out MUCH further ahead than if I'd bought everything here in NYC.

Used my Gold Line RTA to try and optimize everything in my 12 x 20' room, but there are some serious accousitcal limitations to what I can do. I have a serious peak at 33, 60 and 90Hz and a huge gaping hole between 1K and 2.5K (down 30+ dB), Since I'm renting, I'll be damned if I'm going to put any money into someone else's living room!

Still, even with the accoustical problems I have, those Paradigms are simply amazing with every type of source material I can throw at it, be it CDs, ordinary TV or 6.1 DVDs. I'd love to compare this system to one made of cinema-grade JBLs or EVs, etc.
