Default 2-way mini tower

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 ?

Tuning looks higher than 35Hz to me, not often wrong.

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....

Hi,

I like your speakers, well done. You will not be hearing 5Hz through them woofers. Our ears can only hear to 20Hz.

You will damage your speakers by equalizing very low frequency through them, trust me.

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.
