yea...me and HITTLER using compression drivers....he is using RCF drivers and flares and i using 18sound drivers and flares

gfbl should have asked if anyone is using waveguides or HLCD's.

And the general answer is eh, wais dat.

No they're not using them.

time to change that then

^^^^time to go back to the drawing board.. lots of homework to do my friend

waveguides has been used in many many sq cars abroad.. and since i see alot of pple trying to copy what they has been using its a surprise lots of the so called "installers" aint using them

nigel1977 · Postby **nigel1977** » August 21st, 2007, 11:49 am

waveguides have had their time. Thwy were real big when the imaging portion of the iasca scoresheet was worth more points than the tonal accuracy section... Wait, you were there when this was discussed.

The fundamental flaw of a HLCD is its limited lower freq resp. Based purely on what was discussed, and the engineering data, HCLD's can properly do full vocal reproduction. (Ive never seen/heard a HLCD do as low as 200hz).

Go back to your notes. YOU DONT NEED HLCD's. :twisted:

I just add two ah dem alarm horns. Gold.

Sweet mids yo.

MonsterPower · Postby **MonsterPower** » August 21st, 2007, 11:59 am

right nigel i rember that but what about the ones who werent there? ... those who still think that speakers in the doors are the best place for optimal sound reproduction ...

Postby **gfbl** » August 22nd, 2007, 8:22 am

but doesnt horns have their advantages,
"horns will control the dispersion of the sound and in a car because most horns do a great job of attenuating the output of the far left and right sides of the horns when compared to the output directed towards the center of the car...this is good because there will be minimal door reflections and as such the soundstage will be more focused and the system more linear in frequency response ASSUMING the horn itself is quite linear in frequency response". Those were taken from someone else and are not my words

nigel1977 · Postby **nigel1977** » August 22nd, 2007, 8:31 am

Thats 100% correct.

HOWEVER...

As we have learnt, the lower octaves of a Baritone performer can drop down to 200hz, if the baritone is placed on the center of the sound stage, and you are using hlcd's, and the midbass driver is put in the door, where do you think the baritone singer will be reproduced?

Waveguides are excellent, but ony for a narrow band of frequencies.

Postby **gfbl** » August 22nd, 2007, 8:36 am

so the frequencies that are excluded make such a difference when listening to music?is it audible to "regualr" ppl not audiophiles and ppl trained ins uch things?

jeff · Postby **jeff** » August 22nd, 2007, 8:48 am

around 100 to 200 hz.. yep people can hear that

most cars..in trini..dont have much sound in this area tho...and they are quite satisfied with how their music sounds, people only want what they know..so if they accustomed with this they wont know somethings missing there ...scene?

so you cant miss something if it was never there

nigel1977 · Postby **nigel1977** » August 22nd, 2007, 8:48 am

Look at it this way, what is the lowest frequency a waveguide can reproduce? 800, 630, 500?

Where are all the male vocals? Where are all the percussion instruments? Lower than 500? So basically, the waveguide will only optimize the frequencies it can reproduce, and leave out everything else.

Anyone, and I mean anyone can listen to a system and pick up basic instruments. You don't have to own a degree to do that hoss. I can promise you, if you're into learning things like imaging and staging, there is no way you will listen to systems with speakers mounted rearwards of your ears again.

so if i was using hlcd's per say would adding a pair of tweeters help in reproducing all frequencies?

nigel1977 · Postby **nigel1977** » August 22nd, 2007, 8:56 am

youre looking at the wrong end of the spectrum.

casper · Postby **casper** » August 22nd, 2007, 9:06 am

adding tweeters will pick up where the hlcd's has ended

.............

the hlcds drop off in the lower end IE around 200hz and... tweeters are for the upper end of the spectrum...IE Heights...

nigel1977 · Postby **nigel1977** » August 22nd, 2007, 9:17 am

100% correct.

Adding tweeters will extend the response.

From my minute level of research, imaging cues are almost non existent above 6-7k. So I dunno.
