The equalization is done in the AS-EQ1. So u need to permanently put it in ur system.

What is the problem with ur sunfire?

bro, AFAIK, acrylic really not that strong... for sure you cannot blast the sub like normal...

Just as display and to let customers to take a peek

There is 2 types in the market. First is a simple EQ system with only a single point adjustment. You still need REW to map out the problem in your room. EQ1 would be a more advance product as it not only tackle the EQ but also looking into the time domain plus multi point filter. If there is a null in your sitting position, no EQ can help you but to shift your sub around or add in a second sub.

What, even a subwoofer can be DIY'ed? I am so outdated

Most of the US ID sub co started out as DIYers.

no problem but just feel that i haven't tune it to its best performance. i'm still quite new to all these things

Anfieldude can do the tuning on tv and sub at a modest fee. Without an EQ, what he can do is just bass crawl to find the best position of the sub depends on your placement flexibility.

if that's the case then i'll do the sub crawl myself.. but can u give me a few tips on how to solve the current things i'm observing? my current sub placement is at a corner with roughly 3-4 inches from either wall.

- bass sounds a little boomy with certain music
- certain furniture rattles
- windows rattle

can placing a subdude help?

I never use any subdude but you can give it a try. The easiest way to do a sub crawl is to put your sub at the seating position and walk around using your SPL meter. This will show you where are the null and peak. Boomy issue most likely due to certain freq decay issue which can be treated by bass trap or EQ. REW will show you the actual issue in your current setup.

i strongly recommend newbies to pay some1 to do a proper calibration for both audio n video .. without calibration is like buying a sports car without tuning .. if u r interested and planning to buy your own calibration tools then that is a diff story, but if u bought the whole set of av n think u can tune with your own eyes n ears alone then it is very likely u wont get the best out of what u bought

Well said. I don't understand some people would rather put in big $$$ in the display then don't want to pay extra few hundred to get it tuned. Do remember out from the factory it is impossible to get a perfectly tune display out due to component to component variance. Most of the display coming out from factory is too cool in color temp and color is over saturated. It might get your attention at first glance when comparing display side by side but after a while you will start noticing that skin tone is either too green or too red etc...

We are lucky having anfieldude willing to provide the service at minimum cost (and I joke with him he is charging too low, as US calibrator is charging USD 300 per display max 2 input). I had to invest few thousand to get the equipment + many hours of studying in tuning. On top of that, different display had different menu/service menu secret key and tuner will need to look up the info first before performing the service. If I know anfieldude is providing the service few years back, I think I'll get him to do the tuning and call it a day.

Even audio setup is an art as you need to know how to to position the speaker, toe in angle, subwoofer crossover and phase (and I bet a lot of people with sub doesn't know what is the purpose of phase adjustment and how to set it correctly). EQ and room treatment is another topic which get more complicated.

For me i will spend on the modest calibration fee and room treatment (if needed) 1st, instead of spending my money on those crazy priced hdmi..

lol.....

Bro, not easy to convince one to invest in room treatment and seek professional help in calibration.

There are some ppl contacting me to help on audio calibration on their HT sys (aint my cust). When I told them that I charge few hundreds depending on complexity of the HT sys, they and replied,"Wah. Why so expensive. Tuning audio only. Not RM20-RM50 kah?" But there are some who do appreciated good PQ and AQ and do not mind forking $$$ to get the best from their system and room.

RM 50??? Wah, chap lap liao. Petrol and time already cost more than RM 50. If I do professional tuning as living, min RM 180/hr.

Yeah, its interesting how different people react differently to calibration, be it audio or video. I've sometimes asked myself the same question, how one could spend sometimes almost RM20-30k on a home theater and yet, when it comes to a few hundred ringgit to get the home theater equipment to optimal conditions they hesitate. But I guess people are just like that.

Calibration takes time. Also the person doing calibration has normally invested $$ on equipment, but more so invested his/her time in learning the ropes of calibration.

But I guess not all are like that. Most of the people I have had the pleasure of meeting to calibrate their systems, genuinely enjoy their systems after calibration and it enhances their entertainment value afterwards.

The folks of the software that I use for calibration have been urging me to spend some more money on obtaining the Pro license to go with the software that I have but I am contemplating since in Malaysia, there needs to be a little more exposure to the benefits of a properly calibrated AV system

I am now trying to work with the retailers to offer this as an option when they purchase the systems, at least it would be easier for people physicologically if they spend the money all at once.

It's a sign that professional services (at least in this area) are undervalued. People don't appreciate the effort and time involved.

I am afraid that it is indeed so. We still have a long way to go in educating consumers about the importance of audio and visual calibration and how to differentiate / identify good audio or visual.

maybe i'm just being sensitive but i feel as though u guys are bombarding me.... hehe
anyways, i just passed your contact to that someone staying mainland. also, is it possible for me to drop by your place during weekdays to see a difference between calibrated and non-calibrated kuros that has the same menu settings? just wanna know if it's worth it

asherteoh,

This was a general comment and not intended for u. Ur concern is the general concern. Will I see the benefits?

U can drop by, but all my inputs are calibrated. We can try. Maybe on the 428 u can input ur settings.

As I explained, calibration optimizes ur display capabilities. Its ur wish whether u wanna calibrate or not. Also if u r not a fussy guy, don't bother.

Everyone is different, that's what I tried to explain. I apologize if u took the post personally and it is not my intention.
