Even the video doesn't do over 3" of linear excursion justice :D

I hear alot of rattles..... I assume they will be fixed before your compete?

[hamiltonaudio]

what you hear is MAJOR port velocity distorting the mic ;)

nice!

I'm sure it sounds great in person but it really sounds like flatulance in that video. I've noticed that when video recording car stereos...Filmed my friends truck with 6 Alpine Type R 10's playing at a car show and in person it sounded great. Played back the video and nothing but distortion.

thats with RAP MUSIC - i saw it peak into 142.5 or so, but the auto-reset cleared it before I could screen grab :) With some tuning and playing with the vent, there's a solid 143 in this car (thats Termlab at the dash ;) ) with music.

Setup the way it is now, it sounds excellent. That flatulence you hear is a combination of pressure distorting the cam's mic and motor noise from the sub (4 spiders, 4" voice coil and 3"+ of useable excursion is a wee bit noisy tee hee) You don't hear any of it inside the cabin tho....

i cant believe that you only have 143 dB in that, i had 143 int he drivers seat with my two treo street series 12s, but in a sealed box without the amp even being tuned. youve gotta have more like 145 if its tuned right and tested using test tunes.

[hamiltonaudio]

one thing ur not catching - most of my output is in the low to mid 30 hz range. This freakin thing will hold above 140 db, WITH MUSIC, from almost 30 hz on up to a peak of 60 hz. Not sure the Treo's did that ;) And this is only one twelve in a very small vented box <evil grin>

Give me a bigger box and higher tuning and that single 12 will do easy 145's or 146's with music. Its all about compromise. I've been doing this for almost 15 years now, and am still amazed at the output this single driver offers in this setup ;)

oh, for one sub, thats great dB. i assumed that the box was built to maximze the dB, didnt realize that it was built to max dB considering space. 143 is GREAT for that kind of condition.

[hamiltonaudio]

the box is 1.83 cubic feet vented :) HARDLY what you'd consider a "maxed out SPL" design hahah. Its a very attractive box that was built to fit the car well....143.x is just a bonus. I'd LOVE to go toe to toe with just about anything on the Termlab and measure who's loud /down low/...like 40 hz and below. THEN we see where this massive pig shines ;)

[car audio dave]

ok, ill get a cyclone and lets see you bring it. :lol:

i assume you know about them.

[hamiltonaudio]

oh yeah....and there's a reason about 8 of them sold before they stopped bothering.... tee hee. I was more meaning your Treo's ;)

bmoney

[car audio dave]

oh those treos are long gone. sold em on ebay about 3 or 4 years ago.

yea, the cyclone wasnt popular becuase people didnt understand that its a sub-subwoofer. it plays down to like 7 hz. people wanted to bump with it, but its not strong in the 30-70 hz range. its a 30 and below sub.

[djdanger]

I think that video qualifies as SPAM, I saw www.hamiltonaudio.com on the back window.......:D

[RisingX2004]

You should meter it with Bassotronics -"Bass, I love you" Loud and low is the only way to go!!

[RisingX2004]

and yeah those are great numbers for a single 12 in that small of a box

[RisingX2004]

What is your price for one of those anyway?

other than speciality tracks, name me some normal music of any genre that regularly has low frequency information in it that is sub 30 hz :D There ain't very much if any....

If a sub can't play strong 30-80, its not going to sell...and this one proved it. Was it PG that made it, i don't recall...

An MX12 at retail has an MSRP of $999cdn. Of course dealers sell for less ;)

bmoney

[car audio dave]

it was PG.

and my favorite bass test song is thirty-three by smashing pumpkins. constant bass starting at about 35 sec into the song, remaining the duration fot he song. the frequency changes and thats it. listen to that song in a car with no sub and that entire aspect is gone, then add a sub, that bass appears and i sold my target sub every time with that song. ;) im sure it hits <30 hz at some point. but thats rock. real instruments play much lower than the synthesized stuff in rap and hip hop. try that song on your system. :D

hey, i PMed you, did you ever get it?

BTW heres a cyclone for everyone whose wondering what im talking about. no moving cone on this one:

oh and it plays from 11hz-60 hz.i guess i was exagerating. youd still need a 10" subwoofer to go with this.

[hamiltonaudio]

no, no PM for me.... I don't even see where the messaging stuff is on this forum :(

bmoney

[car audio dave]

go back to the mian forum and its at the bottom.

Who says real instruments play lower? Prove it.....
that is a total b.s. statement

[tommymcc]

that box and vehicle doesn't do the XXX sub justice, that think needs to be in large slot ported box in a hatch or a SUV, then i'll make some real numbers

[hamiltonaudio]

a couple clues for ya son -

1. its an MX, not a XXX
2. both the XXX and MX are NOT SPL DRIVERS
3. the entire point was to prove guys like you wrong ;)

With some tuning, the car now puts up 143's with music without issue...I'm sure a 44 is there with tones. I've been around a long time...and 143 is LOUD bro - forget the fact that its a single 12" in a small box in a TRUNKED car.....

I can tell you that ANYONE I demo the car for is astonished at the output...esp when I just finished demo'ing some Sheffield Labs tracks that blew them away.... I'm tired of fart-cannons....this time around was gonna be something that sounds good :)

im an electrical engineer and when youre doing signal processing you can see how low some instruments go. som instruments play below 20 hz (which is the lowest we can hear) while with synthesized music they never record it with lower than 20 hz since its not heard that low.

dont call BS until you know what youre talking about.

lowest bass guitar: 17.32 hz
imperial grand piano: 16.35 hz
hill organ(sydney australia): 8.18 hz

find me a rap song that has frequencies THAT low. you wont.

[hamiltonaudio]

:owned:

I believe thats what you call owned :D I agree with Dave...rap music has some low stuff, but to see any real program material below even 25 hz is really really rare. On the other hand, there's some wicked sub 30 hz information in a LOT of rock music for example...those bass guitars goin way low... and if you mess around with the right music (like the organ stuff) it is seriously sub-sonic....

not that any driver out there will really be able to reproduce such frequencies....

bmoney

[car audio dave]

yea im not saying thats its common, but lots of people think that you need rap music to get the best low music. the truth is that rock and classical music have much lower bass, its just not repetitive like it is in rap and hip hop.

what can i say, some people are ignorant.

[RisingX2004]

I just said real instruments, not actual songs. You can make a tone of any frequency with a tone generator. What instruments can actually play a 1/2hz tone? none ( not that any sub could reproduce it with accuracy)

yeah, its cool to see the cone of a sub moving at < 20hz and the vibrations are sweet but other than that, there isnt much point b/c you cant hear the actual note(s) just the air being moved.

Yes, rock, classical, and a few other types of music can have subsonic bass, but wouldnt you rather listen to stuff you can actually hear?

"what can i say, some people are ignorant."

[car audio dave]

um...whop said anything about 1/2 hz?

have you every listened to classical music on a good system? you can hear the range of music that you never knew was there. most rap sticks to certain frequency ranges while REAL instruments play in the entire 15Hz -20kHz range and then some.

Who says real instruments play lower? Prove it.....
that is a total b.s. statement

i did it. thats the reason for the ingorant comment. in recorded music real instruments play lower than synthesized music. in actual life a 1/2hz tone can be produced, but nobody is stupid enough to record it since first off CDs dont store frequencies that low and no human can hear it.

[RisingX2004]

yeah, and no human can hear anything in the 15-20 hz range either

Yes, i have listened to classical music on a good system, it sounds great.

Fact is real instruments are not the source of the lowest frequency levels in existance, sine wave generators are.
