Dammit, y’all are helping too much!
It's height effects; not orchestra or critical vocals coming from the ceiling :)

They will sound 99% exactly the same in most scenarios for movies...the 8's just dig a little deeper.

Too bad! :(

Not necessarily true. Depends on the content. There are good examples in which the heights are used heavily for the musical score. Multi-channel/Atmos music, etc., etc. The use of heights is well beyond just ambient effects, though yes, there is also plenty of content that does not use them beyond that which probably wouldn't matter much. But it can matter. Depends on what you listen to....:)

I have 8060 towers run full range with speaker wire and no external sub right now. I think it sounds really good in my room. I find myself wanting to add a external sub and run lfe to the towers also to essentially have 3 subwoofers in the room. I like the idea of the towers outputting the below crossover frequencies of the center and surrounds, I feel it helps fill the room better than one sub doing it.

My question is what type of sub pairs best with the passive radiators in the towers? Ported or sealed?

Also from what I understand audyssey will only eq to the drop off of the subs in the towers ( since they are the weakest) so since the -3 is about 39 hz, I assume everything below that for the additional sub is just not eq’ed? Are there any issues with that? Thanks for any advice

I was thinking of doing the same thing. I run BP9020's up front set to small crossed at 80hz with LFE to the powered woofers right now. I like the sound very much. I was talking to Tom at PSA about adding a PSA 15S subwoofer to the mix. He strongly recommends NOT using the smaller (less output) tower subs with LFE with a stronger more output powered subwoofer. Quote: ( they will have a significant "phase shift" relative to any of our products(which are all designed to extend much deeper). This phase shift will cause all sorts of cancellations.) He recommended i do what your doing right now and run speaker wires only to the BP9020's and cross the towers over at 60hz or 80hz and just use the 15S for the lower bass with LFE.

I was thinking the same thing. That the tower subs connected as LFE along with the PSA 15S would help with room nulls and other bass issue's but i guess not? I do have Audyssey XT32. I do know that the dual subwoofers in the towers connected as LFE sound much better then a single lower ouput subwoofer like a SVS SB1000 or RSL 10S speedwoofer which i had in the past.

And many other's on here don't recommend running 2 or 3 different subwoofers together. Try to run one good subwoofer or 2 matched subwoofers for duals.

That’s a bummer that Tom advises against doing this because of cancellations. I always figured this flexibility was one of the strengths of owning these speakers. If you google Sandy Gross set up tips for Goldenear (I read them because he designed def tech and golden ear is very similar) he says that you can connect lfe to towers, then run them full range with an additional subwoofer. Maybe that’s because ge has more powerful amps and digs deeper.

Yeah that is interesting. I run 4 supertowers lfe plus a Psa v1801 soon to be 2. Once I get my second I will switch all speakers to large instead of lfe. I wonder if any of the DT owners in this thread measured what exactly is going on when combining all of these subs. I’m pretty happy with my setup but I’m no bass expert.

Since the passive radiators are ports, you would think ported subs would be the better match, and they might be, but I'm running sealed Rythmiks with my 9040's and they blend very well. So I would make your decision of ported vs sealed upon other factors such as your room size, how much you prioritize low end extension vs mid base punch, and any WAF that might apply.

I thought the same thing when buying the BP9020's. A very versatile speaker in many ways with the powered woofers and atmos modules on top which i have. He did say it wouldn't hurt anything to try it!

Maybe because your running much larger towers with a much larger subwoofer it works fine. That's a lot bass you have going there!:eek:

I would put money on there being some cancelations like Tom has said. Eventually I’ll play around wiith REW and see what’s going on. Once I get my second v1801 I will use those solely for LFE.

I haven’t been on here much lately but I’m reading some of the comments about the towers and running sub cables for LFE. Some of you know I did this awhile back and I’m very pleased with them. Here is an REW measurement of the bass in my room. This is a pic of my VTF-3 MK5 sub by itself and a pic with the BP8080’s and sub together... big difference!

I have to say even though I have a slight beef with Def Tech the company, my setup, the SM 65 LCR and SM 55 surrounds are extremely impressive. I really do love them. Sound for movies and music is extremely good. Very dynamic and beautiful sounding.

Hey @keeper ! I’ve just been working and hanging with the girlfriend! I had to stay off of here because it kept making me want more and spend more money. Plus, it’s football season!And now I know I have a good setup “for now” in the house I’m in. There’s really nothing else I can do with the space I have. I’m hoping to sell within the next two years and buy a new house. Then I’ll be upgrading big time!!!

Thanks for the graphs falconsfan71. So I guess the proof is in the graphs, you didn't experience any cancellations running the built in tower subs using lfe along with an external (more powerful) sub, in fact you experienced a drastic (in my opinion) evening of the lower hz frequencies. That is what i was looking for! thanks. Are those results from Audyssey eq on your denon?

Yes, I have the Denon X4300H 9.2 AVR which of course has Audyssey MultEQ XT32. This is a bad angle for a pic.. it makes the towers look funny or look like they’re leaning or facing out but they’re not.

Nice pics, I like your set up. So out of curiosity the frequency response with all three subs is that even with only audyssey? That’s really good considering audyssey is supposed to stop eq’ing below the tower subs drop off. I only have the 8060 with 10 inch subs but this gives me hope I could mix them with an external sub and get good results. Thanks

Yea, that’s the only way I tested it since that’s how I listen to them. I admit though, for music, as far as detail and clarity, I like my SM45’s better. But for loudness and movies these BP8080’s are bad ass! Getting a bigger center made a big difference in movies also!

@j4894 This was me experimenting with using a PB-1000 connected to my Hsu sub running a splitter. You can see around the 3 minute mark my camera shaking on the back of the sofa! lol
