hi all,

I've got a u-dimension amp running front focal (polykevlar) splits..and I found the focal tweets are really bright and sometimes they are just killing me..
is there anything I should do? change the tweets..any recommendation? or I was told to change the setting in the crossover..will that make much difference? sorry I'm a beginner.. :hehe:

Current system:
Source Unit: Pioneer DEH-P7650MP
Front: Focal Splits (PolyKevlar 136K)
Rear: Focal co-axials
Sub: Jl AUDIO 12"W6
Amp: U-Dimension JR 5.4x - 5 Channels (4x40w and 1x100w at 4 ohm)


PLEASE go to next page to check my solutions...thx!
Thanks!

If you can get to the crossovers you can adjust the attentuation levels, typically they range from -3dB to +3dB.

If that doesn't suit your needs, then perhaps play with the gain controls on your amplifier, turn them to their absolute minimum that you can tolerate listening to. You can also adjust the settings in your Pioneer to see if this helps.

From there it gets to the fun bit: repositioning the tweeter to somewhere that isn't as harsh as what it is now. I suggest using blu-tac to temporarily reposition the tweeter while you have a listen and it makes it easier to adjust on the fly.

Sound deadening will improve the lower-end no doubt. A good sound deadener is anything available- G-Spot, DFQ, Stinger Road Kill, Dynamat, Brown Bread: it is all a definate improvement on nothing at all.

As I'm located in Sydney I've never dealt with stereo shops in Melbourne, only go by their reputation and not personal experience.

Good luck!

^ basically what he said

there should be a attentuation setting on your crossover....it'll turn down volulme level from the tweeters...but generally focals are quite errr snappy, if not find a piece of cloth to cover the sharpness, but make sure its not too thick to block the sounds

Ive never heard tweeters that didn't sound bright at normal attenuation.

Turn the tweeters to -3db and they should sound heaps better.
VinVin
you havnt mounted your tweeters close to your head have you... Sounds like a stupid question to some, but i've seen tweeters in many different places before, like sun-visors, half way up the pillars and on the side pillar where the seat belts are etc...

moving the tweeter to the kickrtim can help tho if they are really bright, but i think, adjusting the equaliser in the HU will dothe most

You are not the first one!!! It is the focal signature that you have to live with it. the woofer if just fantastic but the tweet is the pain in the ass hole. change your caps in the tweet HP circuit to something that have 250 V+. It is going to absord the shhhes down. oil filled type caps work well here. but if you want to make a more expensice move then a pair of new tweet will be nice. and then you can HP the focal tweet at say 10K at 12 Db and use it as ambience. I think SEAS LOTUE tweet is very nice if you have to fit it in a tight space.

search is your friend. there was a similar post "dulling bright tweets" or something similar, quite recently. there was a few really good responses from memory...

Your probally best off getting a set of tweets from the utopias they are no were near as harsh as the polykevlar tweets.
VinVin
I have a pair of Focal TLR Tweeters and they are "Heaven"
joey_kev
thanks for the replies..

this is a pic of the tweeters mounted on the car:


are they mounted correctly for good staging?

btw..where can I get FOCAL TLR tweeters (never heard of them)?
and how much are Focal Utopia tweeters?

thx
icacha
I've always said that Focal tweeters are too harsh on us humans. Now someone that actually admits it biggrin.gif

Move them down to the kicks, that should shut them up a bit. Get yourself some imaging tweeters that are a soft dome so your ears dont get a beating. smile.gif
Mr_Bob
meh, nobody has ever compalined about my focal metal dome tweets tongue.gif
including you George!
if they're too bright for you, try kick mounting, and attenuating them, failing that, look for a new set of tweets.

strangely enough, this problem would best be tackled by improving your midbass.
if you seal and sound deaden your doors, make a solid mount for the midbass driver, and make sure they have ample power... you'll find the tweeters won't be as bright...

If Focal is so good I amwondering why MR_BOB did buy an extra pair of Suprimo instead of Audium TLR.

From the location I have seen in the pic. I think just leave it there but HP it higher and find a good soft home to fill the gap but place it down in the kick position.

I picked up mine off here for $150 I think the TLRs are really expensive along the lines of Dyn Esotar expensive.

because the TLR's are more than double the price ($1600), and at the time there was only 1 set left in the country, interstate, at a company that only wanted to sell at RRP.

trust me, i wanted a set smile.gif

OK OK Benny, I've heard a fair few in my 100 years of dreaming of car audio and I came to the conclusion that it has to be the material that they're made of that makes them sound the way they do for me not to like them. You didn't swap the TN51 for something better? :wink:
golf_bht
Focal mids are one of the best just the tweeter needed to be relocated to the barbage bin
Dave@glprosound
Focal tweeters are very bright, and usualy i set them to -3 / -6 depending on where they are mounted.

only 100 years? what were you doing the first 50 years of your life?
nup, you were listening to the TN51's... it's all about the installation smile.gif
there's no attenuation either, and only 1 parametric band affecting the tweeters, and it's a boost, not a cut.
(well there's a 2nd band, but it's boosting 20Khz)
icacha
Yeah Yeah, yours sound nice I have to admit, but I've heard a heap of Focals and personally dislike them thats all...

hey all...

thanks for all the replies

I've come to two solutions:
1. Upgrade my front splits (focal polykevlar) to Dynaudio 240GT
This will involve selling my rear focal co-axials as well because I was told they do not do much (?)

Reason: I want experience with other speakers and I've heard a lot of good things about dynaudio...
Question: Will my U-Dimension JR 5.4x - 5 Channels (4x40w and 1x100w at 4 ohm) be decent enough to run the Dynaudio 240GT + my 12" JL Audio W6?
Note: I'm not yet looking for upgrading my amp, but are u-dimension and dynaudio a good combination?

2. Stick with my focals! .. and get it tuned...
icacha
Bridge the 4 channels into 2 for the Dyns, 40wrms is a little small as they can take around the 100wrms and more.
obscurusc
Has anybody made a comparision between the dynaudio mids inch versus the utopia mids? Mids ONLY, not talking tweeters... also the audiom utopia mid?
-DJ-
the dyns love the power baby! give em all you got. the 240s are a lovely sounding set of splits.

personally, i'd be more worried about 100watts into a w6! man that thing can take heeeeaps more than that so keep your ear out for clipping. i suppose it depends how loud you like it, ultimately, but be careful. the w6 is a very very lovely sub so it'd be a shame to have smoking voice coils due to dc.

u-dimmension will be a sweet sound with the dyns i'd imagine. they're a clean amp.

in regard to the focals... to my ears the dyns will be a significant improvement and i'd ditch that rearfill whichever route you take if outright SQ is your ultimate goal.

the focal sound is loved by many and it isn't "bad" by any means. mr. bob's system is reputedly very nice! (i'd love to listen to that one day). the dyns are a no-distortion, clean, natural, smooth, *insert appropriate wanky adjective here* speaker. the'd have no problem blowing away any set of focals to my ears... in nearly all respects.

and, obscurusc, the utopia mids are very nice, but different to the dyns. you really need to listen to both and do your homework on speaker characteristics (rolloff, on/off axis response, impedance curves and whatever else...) to make sure i'll mate with your tweeter (or midrange) of choice.

u can run active through ur amp to the fronts,
from there u can lower the tweeters amp gain to be sound decent to u
and the back speakers u still can use ur hu to drive it.
obscurusc
anybody know whereabouts in melbourne I can audition both the utopia and dynaudio at the same time? also anywhere I can audition the utopia audiom mid? I have the utopias mid running with horns and it sounds great, but if the dynaudio mid sounds even better.... then.... :-)

IMO thats really not a worthwhile upgrade its more of sideways step then anything I mean the polykevlars are a bloody nice set of speakers so are the dyns but I don't think they are that much nicer. Your much better off getting a new set of tweets won't cost you 1/3 of the dyns will hey you don't even have to limit yourself to focal tweets why not look at a set of dyn tweets?
