They're measured and labeled in centimeters. The drivers I have are all pretty close.

I'd be interested to know also what, if any, differences there would be between a driver aimed at music and a driver aimed at home theatre? What would make a driver good at both of these tasks?

Should there be accepted standards/consensus as to what constitutes even a minimal "home theatre" - i.e. is 2.1 good enough, or do you want to surf the bleeding edge of whatever the current technology wave is? - that might be a bit easier to enunciate. Absent such, I'd opine that higher excursion / power handling at approximately an octave lower than is found in most musical program material should definitely be near the top of any list.

To repeat myself yet again, I've been quite happy with the performance of a modest - now 7.1- surround system using Mark Audio Alpair drivers for all but the LFE channel for the best part of the last decade. The room is approx 340 ft^2, and I seldom reach and certainly never broach THX reference levels - those things kinda matter, I think.

I agree with Chris, the ability to have a huge dynamic swing for LFE is desirable in movies but almost never needed in music. Being able to locate the voice is hugely important obviously. Most use a centre channel, I however prefer a stereo pair using small drivers with good dispersion. Currently I use a pair of Frugel-Horn Lites with Alpair 5 drivers. These are my favourite speakers EVER. I run them full range and use just small sub which comes in about 70 Hz. The central image with this type of set up has no need for a centre channel. I think that full range drivers are uniquely positioned for this sort of image intelligibility.

For a while I had a pair of Philips 12202/M8 in u-frames crossed at 100Hz to a pair of 15" subwoofers in my living room. Active crossover, DSP, the works.

Was it Hi-Fi? Not exactly.
Was it Home Theater? Not exactly.
Was it awfully fun? Absolutely.

Any time I had new guests, they had to sit through the 1812 Overture at full blast. It was like having actual cannons in the room. Haha!

I sold all of that. I now plan to build a system much like you described. Small full range drivers, subwoofer crossed in at their natural LF roll-off point. I think it's the best of all worlds. Huge deep bass when you need it, and Hi-Fi musicality/pinpoint imaging when you need it.

Mark has left now after a lovely couple of days. I started to cut some of the video and will put it on the KJFaudio you-tube channel as usual as I get it done. Probably one per week for the next couple of months. For now here is a silly video I just posted on my facebook page KJF Audio - Out-takes! | Facebook
