I thought id show off my sound room Speakers I built using MCM 55-3862 these are 2x 6.5" High excursion woofer's that put some amazing Freq, levels down as low as 20hz in sealed cabinet of 1.103 Cft. stuffed wit 2.44 lbs. of fiberglass insulation,they really shine as a mid-woofer and I have cut off @ 3500HZ, with a Vifa 1" dual ring tweeter doing the rest of the job , the vifa's are good for a softer output but to be honest I like a bit more Db. some would say a harsh titanium bullet tweeter as I have in my center channel speaker.... The case was a Zaph design you can find on his site .

I have since ported these with a 2.5" port to 35HZ and let me tell you " these woofers can get down as low as 5 hz and be of good db level, they are truly great little woofer's not to be a sub-woofer .... the Vifa tweeters are more audible now too and stereo imaging has greatly improved "....

With that volume (on the pic) a 2.5" port must be at least 2 feet long to tune it to 35 Hz........ Response down to 5 Hz ? Hmmm. Once I built a speaker that went down to DC -for 3 seconds -when my amp failed....
Im sorry to have to disagree but I own these and have seen and heard these and have reason to lie im not a salesman for MCM speakers. These are in a 1.103 cft. box and the port length is 7.96 and at 5hz the cones are popping out of the frames. Do the math
But to be fare this is the sample I played through my 24bit soundcard to derive at my conclusion , How accurate this sound is may another issue. https://www.youtube.com/watch?v=vNORfd-Xyr4

Hi,
Tedious and pointless claims are just that. At 5Hz the vented
speakers are doing nothing other than just pointlessly wobbling
around, seems you clearly don't understand real vented bass limits.
rgds, sreten.
Driver specs are good for a bass/mid, I don't believe the given FR.
Its been around long enough, if it was good people would have
picked up on it, seems they haven't, draw your own conclusions ....
Its a natural competitor to the DA175 but doesn't get a look in ....
I wonder why ? paper specs are better .... not true perhaps ?

If you don't like what I say then keep it to yourself ******* , I had pointed out I used the Utube audio samples to make this claim now how accurate they are may be another issue . Id suggest you read before you let your *** speak for you....
Anything below 20Hz I can feel inside my body, it knocks me sick. Only ever felt that way djing at a nightclub here in Manchester which was via x12 18" horn subwoofers. And it's no way going to come from them woofers.
Your learning though which we like we all done risky things but wished we didn't or did more research when it goes wrong.
The last thing anyone wants is blown speakers.

Hi,
You don't like being told your full of the proverbial,
and its clear how "intelligent" your response is.
Your speakers don't do 5Hz in any reality and there
is utterly no reason for me to not to say so. I don't
care that that you might thing they do in delusion.
As implied you need to understand speakers more.
rgds, sreten.
That they make farting noises at 5Hz,
simply has nothing to do with 5Hz.

Hi,
Try this test :

The Utube link is utter garbage as a speaker test and
just by listening to it you should know that is the case.

I told you once (hard head ) I was using a Utube sound sample and I even give the link. I admit I do not have testing equipment nor am I interested in buying any . It will not make my speakers sound any better and If I'm unhappy with id rather spend that money on new ones . so take lesson in reading you may learn yourself , and it goes to show your all about telling someone there wrong and trying emulate a smart person yourself
.
try playing this through your speakers and tell me if hear a tone @ 5Hz

I've played it through my PC speakers which has a 3" FR driver of very poor quality at best and you here a tone, a farting tone, a blowing air sound, not bass. I can't see my speaker cone but could imagine it's just wobbling like if playing vinyl through them. I wont bother running them through my Seas speakers and don't recommend you to through yours.
Just because the woofer cone is moving it don't mean there's any audible sound reproducing through them which is classed as frequency response.
p.s. these low frequency tone tests are no good for testing the frequency of your drivers, I have used them years ago in car audio. I don't own any measurement equipment so 'am not one of them'...yet but can imagine testing will be so much better, it means more researching, learning, patience and diy which what it's all about.

Ok thank you for your input , I did hear a very audible as deep growl and the woofer very wobbling displaying more excursion than designed for so yes I would not run it through them again. because these speakers were designed for music and my key boards . They are exception woofers to be 6.5 " ... but music has no audible feq. below 15Hz that I witnessed...

The db level on this 5HZ sample . I have a 200watt nominal per channel amp tuned to the max running my mixer with db level of -36 ----+6 and I pushing -16db with my channel gain level set @ 50%
But without testing equipment its a guess, point being they had allot power behind them to hear it good....
Hey nice system, in your first post you mentioned its a design from Zaph Audio, did you base it on the 'Bargain Aluminium MTM' with the Seas 27TBFCG? You should of used the Seas tweeter, I have a pair there excellent.
Are you using the Dayton DA175s like Zaph? If so I can imagine they will go as deep as between 30Hz and 50Hz. I wouldn't eq them below 50-55Hz and let your subs handle what they can below that.
Here's a page I quickly found on the web search, have a read you may get more interested on other subjects which will lead to understanding more and better results.

No Stewart I used the MCM 55-3862 these are 6.5" High excursion woofer's they had lower hz range than others I looked at . They give some amazing results sealed, and now that I have ported them Im very impressed as I was a little disappointed in the Vifa 1" dual ring tweeter I used as its db level wasn't much to keep up with the woofers but now that they are ported the Vifa have waken up to have a great db level and stereo imagining has greatly improved. Thanks for the link Ill check it out...
