Can someone tell me hoe deep the port tubes go on the M60?
I am looking to buy these speakers. I have QS-8s and they are excellent.
Thanks
I'm sure someone would be able to tell you, but I'm curious as to why you want to know...
LOL, Ken.
I know that they're long enough so that your average cat can't stick its paw all the way through, but short enough so that a gerbil won't get lost in them.
But they're M60s, not your M22s. They could be utterly different :-P
Small,
I'll gladly measure them for you, but only after you tell me why.
Ken, note that the poster is "small".
small, just as a matter of general information I was fortunate to run across in the forum here, you can tune the m60s by stuffing an average sized cat into each port. This of course doesn't give you a specific answer relative to depth, but it should assist you in a rough approximation of the volume capacity of each port.
My technical skills are wanting and I am unable to articulate this answer in a more numerical manner, so I am hopeful Bren will be able to step in and take this to it's next level. I have been reading his posts with some interest and he has displayed a technical expertise that, I believe, we should all strive to emulate.
the ports in my M80 measure about 5 1/4 inch long.
I just pulled out the tape measure, m60 ports: ~2" diameter x ~5.5" depth

For my own sanity, I'm going to assume there was no sarcasm in that. Audio and video (and especially compression schemes) are subjects I've got more than just a passing interest in. I was enraptured by the idea of digital audio when I first realized that using my C64 to poll a 0820ADC a few thousand times a second would give me a digitized audio stream, a lot of trial and error after that gave me the fundamentals.
ie:
a 50%-50% mix of two digital audio signals is
(samp1+samp2)/2 - just an average... that blew my (13 year old) mind
Started playing with ways to compress video images shortly after that... was all just a hobby... then 10 years later, it becomes a part of my job.
Every teen should have a friend with an electrical engineer father with an oscilloscope!

Take heart my friend - that was absolutely a compliment!! I regard your posts as a glimpse into techno knowledge I'll likely never get to otherwise.
.
Amen. Bren, like many of the other regulars here, you educate me in ways that are effective and energizing. This is a good place because of people like you.
Ditto! I just wish you spoke English, though.
Remember! Us poor mortals who are technically challenged can't understand an engineer's foreign language.
I appreciate it, Ray!
And if I do resort to technobabble on anything and someone actually cares for clarification, just let me know? I try not to post 3 page epics.

I should have waited longer to reply so I could see just how many more insults people could throw my way.
The reason I asked for the port parameters is because I currently own QS-8s used in surround in my 7.1 home theater. I am looking to replace my mains, but in order to properly timber match I need speaker parameters.
Since Axiom is so terrible in their descriptions of speakers and performance I am using a computer program to simulate the response, based on the parameters of the drivers and ports etc.
I can't find anyone in my area who carries Axiom, so I can't just drive down the street and listen to em.
It's too expensive to buy em, ship em and then find out they aren't right for my room.
Hope this answers everyone's questions.

small, maybe if you gave us your location in your bio, one of us could turn out to be a neighbor.

Yikes! Those weren't insults. We're just a bit 'sensitive' about our ports, is all.
Hopefully the on-topic responses you got will be helpful.

small, I don't want to belittle anyone's personal efforts to improve their HT, but do you really think that the Axiom M60s will be LESS timbre matched with AXIOM QS8s compared to any other speaker out there?
Have some confidence that the Axiom engineers already know how to design their speakers so they at least match up with other models built within the same company.
A home computer simulation program pales in comparison to the research already put into speaker design regardless of the company (assuming they actually do more research than marketing that is).
Jim, I'm no scientist and I mean no disrespect.
But are you really suggesting that your theoretical analysis of speaker parameters is going to somehow "prove" that M60's do not suitably timbre-match the QS8's? I think you are WAY over analyzing this. Axiom's R/D seems pretty complete, and I'd humbly suggest they have probably already taken care of this analysis to the point where your work is redundant. I mean, it might be an amusing academic exercise, but you really can't know more from a software program than you can from listening, can you? I'd call and talk to the Axiom geeks directly rather than spend a lot of time trying to replicate or disprove complex, existing research. But I never liked Physics anyway.
What mains are you using now?
If you like the QS8's, you're probably going to like the M60's.

My apologies if you were insulted.
You DO have to admit that it was a pretty non-standard question to ask.
You know what they say, "curious minds want to know". You've struck a goldmine of curious minds in this place.
Ford the beauty of that is that it's 100% mathematically true (If you add that little "repeating forever" bar over the 9s that is...)
Jim, what I was going to use as a little bit of audio humor if someone had followed up on my "small" comment is apparently not too far from what you actually have in mind. I was going to protest that the reference was merely to Richard Small of the Thiele-Small parameters and that you were interested in enclosure tuning. As chess indicated, I don't really believe that making use of the parameters can be done to give you the accurate timbre comparison that you're looking for.
Well, I guess I've got to come clean.
I really didn't intend to imply what people thought I did with my first reply. I was reacting to the newish propensity of certain people around here to diagnose how the speakers will sound or if they were worth the money by dissecting the speakers and asking about their components. Honestly, I didn't get what I said until about 3 days ago.... Guess I'm a bit dense.
However, I stand by what Chess et al. say. I think Axiom's got the timbre matching covered a bit better than any computer modeling program based on speaker parameters does.
"I should have waited longer to reply so I could see just how many more insults people could throw my way." That's some of these guys genius. You're either part of the club, or you're not...It's kind of like a college fraternity.
Good luck in your search.

OK...I just went back and re-read all the posts prior to this one...I can't see anywhere that you were insulted. yeah, you got some goofy responses, but you also to at least two people who actually did the measurement for you - regardless of the reason you asked.
Relax, we're a bunch of clowns and have fun around here.
tony,
If you really hate us all so much, why be a masochist and continue to visit?

I've been here about 6 months and I've yet to see anyone be insulted here besides all the Eastern seaboarders making fahn of each others ahck-scents.
I think it's more like a comedy club - some get the joke, some don't.

I am pleased that I stumbled across this board because of the sense of community, willingness to share opinions and knowledge, wit and humor displayed here. With very few exceptions, no one seems to take themselves or the subject matter too seriously and the help provided is priceless and relatively unbiased except to the common thread that Axioms are excellent products. The amount of opinions offered AND supported relative to other speakers is refreshing and offers a nice counterbalance. The exchange of personal information with each other and off-topic conversations is not to be found elsewhere. Most other forums are quite a bit less congenial.
Having said the above, I'm usually very disappointed when I see the kind of discussion that is starting here. I'm going to make an exception and participate in this one. Tony, to be blunt, your posts always seem to have an edge to them with an intent to stick a finger in someone's eye. I'm not really sure what is causing this, although I don't believe it has much to do with this forum. I've seen you include things in your posts like sarcastic accusations of cliquishness, acerbic comments about being a fraternity, petulant comments about "if you don't agree with me I'll quit" and a selection of other critical comments. I've only been here for a couple of months, but felt accepted from day one and that participation was encouraged. I've actually made a couple of new friends and learned quite a bit here. I'm not sure what is driving you, but you might be happier to get over yourself and participate, rather than chide folks at each opportunity. Your information is knowledgeable, concise and contributes to the benefit of all, but it needs to come in a more positive way. I'd prefer to see you here, but I'd like to see you also spread a little sunhine - it couldn't hurt. You will realize what I am saying if you stop and think as you reach for your keyboard to craft an in depth rebuttal and a lengthy diatribe about how wrong I and the other commentors are about what we have just posted.
I have nothing more to say on this subject, will not rebut any further comments on the subject and will not re-enter this thread.
ray, maybe your wife will post to this thread....just kidding, well said.

Im glad this thread has allowed everyone to O-Pine so much.
All the discussion about timber matching would be great if I were only matching Axiom products but I am not, I have numerous types of speakers in this setup. Maybe someday I'll send some pictures. I built this room specifically as a theater. Axiom does not provide good specs for their products. If anyone knows where I could go to get them, it would be a great help. It is good to know everyone loves their speakers, that's encouraging. Being a soldier, Im not much for all the extraneous discussion. I try to stick to the subject and hopefully get some usefull answers.
I have posted a BIO.
Regards.
Jim
Have you contacted Axiom directly with your questions? They will probably be a better source of technical information than most around here.
Unfortunately (?), some of us around here are not soldiers, and we enjoy the extraneous discussion.
*whew* Glad I rolled out of the Canadian Armed Forces somewhere between the haircut and basic (reasons: combination of an ill stepdaughter and hearing the Leve11ers'
Another Man's Cause)... I'm a big fan of a free and open dialog.

Thanks for the info Everyone. I am ordering M80s. I hope the 4 ohm thing works out, if not, I will get an additional amp or make one. The responses from the program I used were incredibly close to the data sent to me by an engineer friend from Home Theater Magazine. So if you get the numbers right, you get the answers. Axiom will still not respond to my questions. Oh well, I am putting my faith in their work.
To answer some other questions:
I usually love fun, wacky conversation, in context; but in this instance, I posted the thread to get a very simple answer to a technical question and hoped that a fellow speaker owner would break out a tape measure and give a little assitance. Something I would gladly do for anyone else. What I got was alot of very weird responses. Thank you to everyone who PM-ed me, that was very nice of you.
I think some people just like to hear themselves type....probably the same type of people who call talk radio on a regular basis and buy things from infomercials.
It would have been nice if the engineers from Axiom responded to my e-mail, engineer to engineer but oh well.
If anyone has any questions about making their own subwoofers or installing base shakers or environmental devices to home theater seats let me know. Id'e be glad to assist.
During certain movie scenes, a seatbelt is required in my house.
After flying military helicopters, I guess you're addicted to all that spine-rattling rumbing and need to replicate it as closely as possible in your HT, eh?
About this part of your post, though:

...Was it really necessary? It's like me walking into a BBQ with your buddies and dissing your haircuts.
Oops! Is that a finger I feel sticking in my eye?
