@lvins - nice speakers you got there! DIY mo ba yang Karlson enclosures?

Not vintage. May 3-4". May 8". I think galing sa mga busted speakers nila. But it's dirt cheap. Yun nakita kong 3" that looks like woofer sells for P60 only. Great for DIY projects if you initially don't want to spend much. Not sure kung new tweeters din for ambient sound like the topic discussed sa As audio thread. Hehe!

Kakainis, sana may malapit na HMR dito. Sarap tignan hehe, mura naman

Tago mo na lang for future projects as long as gamitin mo siya within 2 years, or you have to wrap it properly.

Hehehe sobra na for now e (Actually, there's no such thing as too much in DIY haha).

Congratulations to all DIY-ers! Your projects are even better than those of branded speakers! Keep 'em coming!

Thanks Sir,Yup downloaded the specs for Karlson 12,swak na swak ang Jensen Delta.Bagay sya talaga for coaxials 98db and up,I tried Philips AD1970M but for me Triaxials/coaxials are best for these type of enclosures.
Ganda details,bass is extraordinary...IMHO..anyway sound is always subjective..

Signature series sir

naging signature series nga yung isang box,hirap talaga kapag may terrible 2 year old.

Galing! I've been contemplating on building Karlson cabs since last year, naghahanap pa ng suitable drivers & lakas ng loob

The aperture (unique opening on the front) is what gives this a unique sound. A tighter/punchier bass & rolled off highs are some of the most used description to the sound character from this cabs, the aperture focuses the bass dispersion while tames the highs of some drivers

Ayos lang yan sir, also in the same boat as yours. Ganyan talaga pag may little chikiting pa. But I know you will agree with me in saying that any speakers or any audio gear, no matter how good they sound can't even come close to the happiness the little chikiting brings

Guys,

I need a quick help, nahirapan na ako magresearch ulit, medyo rush kasi. Naresearch ko na dati pero nakalimutan ko na ulit :p

I need to a 1.2uf capacitor to be used for 1st order crossover on a tweeter, pero that value is rarely made, so nearest is using two 0.56uf capacitors (=1.12uf ok na rin) . Ano ba configuration, in PARALLEL or SERIES? And sa + ng tweeter ilalagay di ba? And kailangan ba ireverse ang polarity?

Note: No more resistor will be installed, may attenuator na ako

parallel. wire it in series and capacitance will reduce it in half.

no use agonizing over exact values, stick a 1ufd cap in there and be done with it...

1 ufd film caps are very easy to get, meron nyan sa deeco...
meron din nyan dito...http://www.epektos.com/product/ac2bf3a6-da48-4710-8750-fecf959a1afc.aspx

Thanks for the feedback sir, pero nakaorder na ako kanina e:p
Hopefully tama naman sana ang binili ko

For brevity, your plan is correct. Parallel two 0.56uf caps to get as close to 1.2uf required.

Yup sa + ng tweeter mo ilagay para lahat ng - sama sama unless you want it to be out of phase, baligtad mo na lang.

A simple tip I can give you is that as you increase octave of the crossover you should at least target the computed capacitance required pero pag 1st order lang ok pa medyo malayo ang values sir.

Bigla kong naalala, 1uf is 20khz cutoff @ 8 ohms. Ganun kataas cut-off for the super tweeter?

Yes, sometimes even higher. It assumes that the main drivers are capable of the nominal bandwidth of up to 20KHz. Otherwise you'll have high frequency splash over.

Ah ok. I thought king would love to add some air and i would go for 12khz-16khz region

Paeng, yun yung target ko kasi around 16-17khz ang sakto sa akin na cut-off.
But yes, kung sakaling 1uf (20khz), okay pa rin. At 20khz may presence pa rin, but siguro 6db slope kasi e

you also need to consider the source impedance as well as the load....
capacitors themselves have a slope of 6db per octave....
starting at a corner frequency determined by the source impedance and load...

First off, sorry for barging into this thread. I'm not a DIY'er, but would like to share this awesome find.

Medyo nag-slow pace sa project.

Test fitting the cabinet accessories before finishing.

Fitting the binding posts and plate

Close-up of the binding posts

Completed the installation of the damping foam and fiberglass combination

Installed the adjustable footers

Test fitting the driver.

Still in the process of doing the wooden ring surround outside the drivers.

Malapit na matapos! Finishing na.

Yung Kensington actually ang inspiration nito. May konti lang revisions like yung sa bandang ilalim ng cabinet especially yung experimental porting nito.
