Axiom Home Page Forums General Discussion What's New At Axiom New LFR1100 woofer

Hi Dakkon,

There is a last little bit we are doing on the LFR1100 and then I will post the graph. Should be by the end of the week.

I'm looking forward to somebody with upgradeitis making me a sweet deal for their M80v3's.

Here's a sweet deal. too bad pickup only.

wow that's a smoking deal. what gives I wonder?

im not sure but it looks like 2 ep600's in there.

I know, that blew me away when I saw the price. To bad I'm on the other side of Canada :p

Maybe he can't afford those plus all of the gym gear. The Axes have to go....

Fred, the only reason that I replied to that post was the comment that the "extra throw" would allow it to "reach lower". Yesterday I had run some of Keele's equations by hand(with the help of my pocket calculator). The results I got were in close agreement with your numbers and I didn't see a good reason to discuss them further. Briefly, using Vas and Qts I got an "ideal" enclosure volume of 1.55 cu ft., using Fs and Qts a -3dB frequency of 25.9Hz and again using Fs and Qts a 31.6Hz enclosure tune.

So, the point, as I mentioned above, is simply that the Xmax isn't a controlling factor in the frequency of the extension, but rather, along with other factors(primarily the effective diameter of the woofer cone)affects maximum volume capability.

Thank you John. Your post gave me a big smile.

Is it not fair to say though, that the extra xmax will help down low as well? I think I was only half wrong this time.

Regardless, I think this looks like a very fine woofer, however it is used.

I bet those new M100 can even replace a subwoofer for movie purpose. Did I am wrong because I have run a 5.0 setup (M80-VP150-QS8) for a while and never felt I missed much in the LFE.
