Thank you for those explanations, nice to deal with a company run by real people! By the way, when the M80's do arrive, I will need to re-calibrate my Harman Kardon 1650. I went into the menu and got totally turned around: what is the "transducer size" for the original ep500 sub and what crossover settings should I use for everything else? Will all of these be correct if I use the EZY automatic set up? Forget calling HK and talking to India. Is there anyone out there that knows how to get the best out of this HK unit? (I know it is not too high end but its what I have for now). Thanks in advance.

Is there a M3 powered version in your plan by the way? While they are great bookshelf with accurate bass I think they would win with a little extra bass output.

Someone mentioned before (forget who) that the high powered version of the bass drivers are designed for dedicated woofer applications in a speaker and not as a midrange/woofer like what you see in the standard 6.5" drive unit used in the M3.

Few quick and simple questions.

1. Will the High Powered M80s provide a more aggressive base sound at moderate to high volume compared to the regular M80s?

2. If so, will the difference be signficant enough for me to go "whoah, thats more base. I can feel the pressure in my chest" or will the difference be subtle?

3. What the heck is SPL? I've been reading that its just a calculation based on watts, distance from a speaker etc. How does SPL actually manifest itself in a tangile way?

4. Do you sacrifice anything by going to the high powered version?

I'm using a Denon x4000 receiver.

Thanks.

SPL is Sound Pressure Level, measured in dB (Decibels). It's how loud the sound is that's reaching your ears. That's why distance matters, the pressure level drops as it covers a larger area.

It takes twice the power to affect a 3 dB increase, but the human ear needs about 10 dB for it to seem that the volume level has doubled.

Well the high powered M80s have an SPL that's 1dB lower than the regular. That confuses me. I'm considering them because I want a more robust bass output. If the SPL is lower wouldn't that mean less air is being moved?

If so why the higher price?

That's sensitivity, or how loud a speaker will be when only given 1 Watt (and listening at 1 meter away). So the version with greater power handling needs a tiny bit more power to reach the same output level.

Another thing to consider is for dbl the volumn level take double the wattage. That said, with your X4000 you would run out pretty fast. I am told these are great if you have a high power amp. ADA 1250 or Emotiva AXP2 etc.

These HP Speakers will probably suck the power supply in the Denon dry pretty fast.

I don't understand how loud you really need to play, I have a HK 3490 now and M80's I sit in a room 20 x 13 x 8 and Speakers are set 11 ft apart I sit 13 ft away and if I get to +5 I sure as heck can feel air movement and I only got two Energy 10ESW subs. This reciever is a 2ch 165w per, I couldn't even phathom a 450 w power amp at loud volumn unless it was outdoors wink

I haven't gotten past 0 yet. It's not so much volume that I'm looking for. I want a little umfp in my chest.

I wonder why the mids don't need to be upgraded to a high power version? Will the mids or the tweeters be the weakest link now in terms of distortion at high volume?

run EZY setup. it will select a crossover point for you. You can change it is you need to later. M80 usually a good point to start is 60hz specially with a EP500.
