It took me all night to setup everything, move out the extra speakers, and change the cables from bananas to speakon. I started to measure at 3 feet away each speaker to EQ and I noticed it was not bad so being tired and my friend wanted to hear something before it got too late I played Dave Mathews and the Beginning of Resident Evil after life(to hear midbass from the T-39's). These do not sound like the other DR's I had. I hooked these up without a XO and let them play together and I can tell you it works great. The T-39's play from 40-300hz in my room and above 300hz they drop off fast. So with no tweaking whatsoever(meaning it can only get much better) the DR-200 and T-39 combo sound incredible. I could not take them to reference yet because I have a big peak at 10khz which can take your head off. I played it at -5MV and it was very clear and very dynamic. The DR's are very picky on placement and needed to be aimed down at my ear level. They also need a little break in. I can honestly say that this setup has everything. It has the HF energy of the M&K's, the best dynamics of any, and the big sound and 95% the midbass of the JBL's. Yes, the T-39's almost have the midbass of the JBL dual 15's. I have to take a good pic of the front stage, pretty impressive looking. Once I tame that HF peak I will turn it up more. I only watched one scene from one movie so I have lots to do. I am excited that this system sound this good out of the box. I am literally running the DR's and T-39's in parallel to one channel of my amp as one speaker and it was flatter than the DR's alone but these are different DR's from before.

That's awesome MK. It sounds like you might have something you might be happy with...for a while. Considering this set-up could reasonably referred to as "reference", I'm more excited than ever to hear your impressions comparing these to the other speakers you have in the wings.

I have 3 speakers left to compare. I would say these are my top dog for sure. This setup is exactly 15 feet wide including the subs. I am using 2 of the 30 inch T-39's and the center has a 20 inch T-39 but will have 2 DR-200's stacked.

The question is should I use 2 30 inch T-39's(mains) with a 20 inch for a center or use the twenty inch for the mains with one 30 inch for center? The differences between the 30 inch and 20 inch are the 30 inch should have a higher sensitivity.
I would place the 30" with the mains and use the 20" for the center.

I guess if I had read to the end of the thread before posting, I would have seen that is what you did.

The 30 inch seem much bigger than the 20 inch. I will take a pic in an hour or so and maybe a response from the center channel.

That's a lot of 10 to 80hz output with those three T39s and the four F20s heh

Actually the response from both where they overlap is from 80-300hz an where lots of punch and impact is.

I can't wait to see some pictures of this now. It has to be packed pretty good with enclosures

OK, I went home for lunch to EQ the front 3 channels at the speakers(3 feet) and sub but I ran out of time for the subs(moved them slightly). I never got a chance to listen to them yet but here they are.

Front right speaker(DR-200 and 30 inch wide T-39)



Center speaker(DR-200 and 20 inch wide T-39) Disregard the output below 100hz as I had the subs on for that one(sharing same amp)



Left front main(Dr-200 and 30 inch wide T-39)



Here is what is lurking behind the screen.

MK, is that still the rat shack SPL meter you're using?

Yes, I still need to get a long xlr cable to connect to the behringer mic. I ran the sweep from 40hz to 20khz and it was strong all the way. The highs are very extended. I am running a 80hz XO to my subs so there is a rolloff starting at 100hz until I add the subs as you can see with the center channel response which uses the same amp as the subs. I didn't bother to unplug the interconnects. I will go home and listen to this and take a LP response now. I am curious how flat they will be after 10 more feet. EQing is a breeze now and it takes me about 5 minutes to manually input about 10 filters. Next up are the subs to make sure they are still flat. I am using a 1/3 smoothed response because I read that is how we hear. Otherwise the higher in frequency you go it becomes a mess.
post #253 of 1141
Do you use a more fine-grained response to do the EQing?

That may be the most incredibly intimidating home theater audio setup I've ever seen.... I LOVE IT!!! Simply amazing!
post #255 of 1141
I've always thought that it was 1/6 smoothing for the "what we can hear", but it really is pretty irrelevant either way

Holy crap!! I just played Dave Mathews at -5 mv and the energy was amazing. All acoustic and my skin was vibrating the whole time. These sound really clear and more live than an audiophile speaker which sounds softer. You either love this type of sound or you don't. I happen to like it. I eq'd the subs again. Response coming but still with rs meter on c-weighting and no files. I bet the low end will come up a bit with the new mic.

MK which 8" did you use in your DR200?

And are you just using the basic 10" or what are you using in your T39's?

When ever down the road I would love to see what the center channel alone can do. I was looking at the DR200/T39 20" wide combo earlier because thats what I could fit in my living room. Wifey said I should just build the DR250 and leave the T39 out of it for budget constraints but I dunno.

I am not sure which 8 is in there but all the t-39's have the delta 12lf.

I figure you need a stand for the dr 200 so why not a speaker. You instantly can tell when you have great Midbass. I have not run my go to demos yet.

The piezzos can get a little rough at extreme levels meaning hard sounding. I have also noticed that reference levels is even louder now. Playing at reference is a challenge now. Btw I am listening to DTS-HD now and not HBR DTS.
post #262 of 1141
I'm smooth all the way up to the extremes, but I rarely listen at reference.
post #263 of 1141
I remember a while back when I asked about the DR for HT Bill I think suggested using the BMS 4550 or something like that. I will look at my old thread and see what he said. It was a BMS CD on a horn just not sure which BMS driver.

Oh and I cant wait to see what you think with the Tumbler scene from Batman. You mentioned it a while ago on your old JBL setup....I think... Either way just looking at seeing how much these drivers will cost me and see how quickly I can have a similar setup minus the subs.

Extremes are over reference levels. Reference is louder with this processor and I am not sure why. I just have to turn it down not a big problem.

MK, I'm sure you have, but I'll ask anyway. Did you confirm with the SPL meter that you are properly calibrated to 75 or 85 dB?(whichever your processor uses)

Of course I did.

Here is my subs response



I am having a hard time balancing the loudness of my subs and speakers for some reason. When my subs are set to 75 db's with the rest of the speakers and watching a movie I hardly get any bass like before. I only moved the outside subs into the corners and not behind the screen. I have to turn it up to 87 db's when calibrating just to hit the same spl during a movie. Something seems off to me. Notice the graph for the subs are usually around 85-105 db's for me and not it is 65 db's and I did not change the volume. Why is it so low? I might have to reboot something. Anyways, the DR's are very clear at reference and lets in more detail than I can remember. It is just louder than before but the bass is less. The speakers are set to 75 db's and the subs are set to 87db's.

MK have you changed something since before? Are the F20 subs out of phase with the other speakers and subs and causing them to output lower due to wave cancellation? Seems like the T39s are the only thing really that could cause that. If you turn off/disable output on everything but the main subs that are having the problem and run the same exact sequence does it still show as too low or does the output boost up? If it jumps that would indicate phase cancellation of some kind and you could try reversing the leads or use your eq'ing rig to mess with phase. I didn't realize I had a phase problem until running Yamaha's YPAO system that indicated my main speakers were all running reversed compared to the subs.

I would assume that if my graphs are all within +/- 3db's from 15-10khz they should be in phase, no? I know what assume means I wonder if having much more HF energy is the culprit for louder reference. My jbl's dropped after 12khz and the M&K's and the DR's both extend much higher and they both sound almost too loud at reference. The sub output I will figure out. I will check all the connections, etc.... I will have my first review(a friend) come over to hear the BFM system tonight. I will make sure it is setup perfectly first.

Did you do the Check Levels step in REW?

http://www.hometheatershack.com/room...level.html#top

If your SPL meter shows 75 from the LP/mic position when running pink noise from REW, but REW doesn't, you just need to adjust the input level on the sound card until the REW SPL meter matches the level that your standalone SPL meter shows.
