I could DIY on the subs to save money but I'm worried if I will just spend money for not so good output. If Subs are that easy to make why do people spend 3K to buy just one ;)
The simple answer is they are chicken to try something new lol. Store/ID subs are bound by a few things. Size/weight/price. DIY'ers don't have those restrictions. We don't have to ship anything, make unique designs that fit into what were are doing and can use the highest possible quality of drivers/materials possible.

And I'm extra lucky in that I have a world class sub designer/builder 15 mins away from my house!

you are very welcome, it looks great and must sound incredible. For what ever its worth I have 3 OS's and love them, but your set up still makes me think... how about 4 to 8 of those puppies in my room? Great stuff, the only problem with this thread is more of us are not closer geographically.

Before I actually decided to go DIY and build my subs I was VERY close to buying a OS LFU, and was actually ready to drop the cash on one even though it would have cost me close to 4 grand after exchange rate because I'm in Canada, shipping and taxes. But the more I read about building my own subs and talking with a few forum members, the more I realize that was the route for me.


If you built eight subs like mine; that would literally be insane. Four up front and four out back would be outright scary :)

I sold many a Bose system in the late 90's/early 2000's when I was with Circuit City.

The margins in that were insane. I remember the most expensive Lifestyle system we sold was $2999 and our employee cost, direct from Bose, was only $999 with shipping. Still wasn't cheap enough for me buy.

I did take full advantage of the Polk direct programs. My first serious, non HTIB, surround system was the Polk 5000 system.... That is what started it all. :)
Is Circuit City still around. In my region Best Buy put them to rest.

Can a house made of studs and drywall handle 8 subs on the second floor? When my kid runs on the second floor I can hear them. What kind of damage can 8 subs with that kind of power do? :eek:

Thanks jbrown15. will wait for Archea to respond and send him PM also to remind.

One question for you. I see that you have QS8 surrounds; any reason you didn't go for Slanted 8HT's from JTR? Same on the sub.
Smuggy - you could PM RandyBessinger who owns Procellas and has also heard JTR speakers many times.

Can't wait to build mines too. Gonna have my weekends back. So 2 or maybe 4 sealed FTW 21's up front next to the 215's would be stellar. While the 4 S2's take the sidelines and the rears...

Forums like these keep you hooked. Building a sub was never my plan but I've been reading the DIY Sub thread for the last 2 hours.

http://www.diysoundgroup.com/review/product/list/id/248/category/64/

Can we just buy the ready made Sub box from the link above, paint it, get the UXL-18 driver, amp, wires etc and be done...It seems doable but I need to do more reading. So, from speakers forum I'd be moving to the DIY subforum..lol

jbrown15: do you have a thread or detailed instructions on how you built your Subs? Thx

My brother who's a carpenter finisher for 10 years. Now a foreman at his job. I showed em some pictures of sub cabs with all the bracing on them. One word out of em.. " shh, Easy!". When are we gonna start? Lol...

^ Rhed, you are really getting out of control. Keep it up! :)

Here's my build thread. http://www.avsforum.com/forum/155-diy-speakers-subs/1506201-ltd-m18-sub-build.html

I don't know what your room is like but if you have a false wall/AT screen setup like mine to hide the subs you can get pretty crazy with with multiple subs.

Send me a pm if you have any questions.

Yes, planning for a baffle wall with a Seymour AT screen. Sony PJ. The bigger issue is wife doesn't agree with 10-12K on speakers :D so I need to work that out. If I can save money on subs and clear out the JTR vs Procella conundrum, that would help. I'm clear on the PJ, screen etc.

Will JTR be at cedia?

I don't think you'll find JTR speakers at cedia, where are you located? I think you're best bet to hear some JTR's is right hear, find someone close to you and see if they'll let you have a listen.

I have to say if you're mostly going to use the speakers for movies and tv the 228HT's are one of the best bang for buck speakers on the market. They can easily hang with some pretty expensive speakers.

The JTR speakers are voiced flat which is Jeff's preference but it is counter to what most people find appealing. To counter this you just need to boost the mid-bass up with an EQ to get the sound you want. The speakers are more than capable enough to take the boost you give them and no suffer and ill consequences. Now the only thing that boosting cannot do is overcome room issues. The only way to overcome these are to either move the speaker placement or modify the room. You mentioned a 100Hz hole which you couldn't EQ out which would be due to a room / speaker placement issue. http://peavey.com/support/technotes/soundsystems/boundarycancellation.cfm

I have had my T12s for a couple years now and recently EQ'd them which made the mid-bass and even bass from them really stand out. The bass was enough to where I thought the subs kicked on in addition to the L / R speakers.

Added in Edit: You mentioned that the speakers had the same FR in two rooms. If this is the case I would say possibly a faulty speaker. One sure fire way to test, but a pain, would be to test the FR out in an open field. ;)
Can you upload your FR response? Would love to see before and after :)

If I am reading these charts and the room has an impact on mid bass....how can adding a MBM help?[/QUOTE]

Different driver location can not have a dip at that FR. Why most say subs usually don't measure best where main speakers are. But each room is different.

I am looking at switching routes slightly and going from stands for my Noesis 228HT to placing them on top of my subs. Any suggestions on the best thing to use to isolate them so there isn't undesired movement/scratching?
I have my 228s on top of my Submersives. I am sure it is not ideal but you do what you have to.
My subs are sealed with dual opposing drives so they don't vibrate at all. I just use small stick on felt pads to reduce any marking on the finish. If you have single driver subs they probably really shake at times.
I have Triple 8's LP's on top of my two submersives flanked at the LR positions. Felt pads is all and they never move an inch :)

Everybody is happy with Bose till they hear a full JTR set up. :) You should see if there is anybody near by that would be willing to give you a demo.
Papalock, don't you have a youtube vid of your epic bose subwoofer moving air?

Rhed is actually causing the waves :) 4-21's with quad Cap S2's? Straight N8 status...almost...

That's funny bro! Btw, I'm going on a fishing trip over to south point at the Big island soon. For some ulua fishing. I figured you know where that is since you were in the Big island before. Can't hardly wait. Haven't cast my poles and conventionals for a long time..
