Btw, OT a bit.... I am planning to build a PB12-Plus by using the acrylic panel just to show fellow visitors during KLIAV show. It might not resemble the original look but probably close to it. I had a friend that could help me out on that but have to check on the cost to cut and build such cabinet.

That would be cool. An 'inside look' at SVS smile.gif

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  shocking.gif  blink.gif and replied,"Wah. Why so expensive. Tuning audio only. Not RM20-RM50 kah?"  doh.gif 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.

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

Thanks for sharing the build process. Good to see this being done by one of the LYN forumer.

It's gonna be a monster!

Congrats on finishing the ED sub.

Hey, didn't know you ordered the JTRs too. I hear very good things about them.

Coming 2 weeks would be very busy re-arrange all speakers, equipment and the damn heavy sub. You need 2 people to drag the sub, 3 people to carry it. Also need to DIY the speaker stand as the height for JTR T8 is around 26.5 inch. Can't find anything that is 10" for speaker stand. All 3 speakers standing vertically so this would be perfect for matching front speakers.

Will let you guys know how JTR T8 perform. Based on the rave review on avsforum, I'm expecting the performance to blow me away (well, at least blow my balls away!).

Will eagerly await your review on the ED and JTR. Hope can visit you next time I'm in PG.

I recall you said your aim is to achieve ref level for your HT system. Do u actually listen at ref level?

Ha-ha, yeah the disadvantage of these big subs is the time and effort needed to move them. Not to mention the lesser options in placement around the room.

Just saw your impression and pic. So your ED is behind the screen?

I'm sure it's a few steps up from the DD-12. You now have much more cone area!

Would be good to see your REW graphs for the in room response. I'm still trying to dial in the PB13, at the moment facing a dip in the 40-80 Hz region which is a bummer since a lot of mid bass impact is in that range. Haven't run MultEQ XT to see how much can be corrected.

Having an AT screen is nice and makes the HT look neater. However, you will need a rather long room for it because you need to allocate at least 2.5 - 3 feet behind the screen for the speakers and sub. Effectively your viewing distance is shortened by 3 feet since you have to push the screen farther out. If you have the length and budget then go for it.

Otherwise I think a solution like yours (pierreye) is neat also. Do a false wall and mount the LCR and sub below the screen.

Hey pierreye, does your screen vibrate during bass heavy scenes? With moving pictures it's hard to detect but if I overlay my projector's menu on it I can see the words blur a bit when the bass hits.

Yup the Carada tension is quite tight. I have one too.

The vibrations are hard to detect when watching movies. U need to overlay something like text on top then can see easier (if any).
