Definitive Owners Thread - Page 936

Yes the ones I have are the st so there slight taller then the sts versions and yes they look very similar to the pro monitor 1000s those are what I am currently using as my surround speakers they have the same mid-range drivers only 2 instead of the one and the same tweeters so the timbre match excellently. I'm currently trying to get a pair of the sts for my surround backs so when I move I can complete my 7.1 setup as well as the cs8080hd to replace my 8040 which will move to my living room set up instead of the theater room

My bad, it was the St's I seen and heard. Got them mixed up.

It's alright but yea they are amazing I love them I use the towers subs as my LFE channel I'm debating on adding a dedicated sub to the system

James I'm curios about your 7001 as a center. Does the passive radiator down firing into the entertainment center cause any issues and I heard you should never use bipolar on a center channel due to lobing issues. Are you getting any of those effects?

I have the BP8060ST's and they sound great with music, but are lacking for movies, they just don't dig down deep enough.
I have ordered an SVS PC12-PLUS to help with the bottom end. When it arrives I get to figure out how to best integrate it into the system.
I love the 8060's but I just want more...

My wife thinks I'm nuts....LOL

Mine thanks the same thing I'm thinking about getting a supercube but I really don't need that much more of a bottom end as it is now with my two towers I have 600 watts of base plus four passive radiators, and trust me when I say those things will rattle me

I spoke with Chet on Friday he actually liked the idea and wanted some feedback from me after installed. Mentioned nothing about lobing what do you mean ? As far as the passive he said I only need an inch or two and I do have it angled giving it more than needed. Attached a couple pics. Sounds great

Yep, that's what I have in the 8060's. For music I don't need any more, with movies....they're just not cutting it.
It could be room dynamics that are doing it to my setup...I don't know...
From all the reviews I've read, unless you are looking at the reference or trinity, there better bang for the buck solutions.
I love the DefTech towers....just want a little bit more on the bottom end...

Have you tried adjust your channel level I know on mine the auto calibration turns my sub way down so normally once I run a cal I go and adjust all my channel levels

James my version of lobing is when two speakers are transmitting the same info and you get cancellations of signals. With both forward and rearward speakers transmitting the same signal I would assume that some cancellation is going on. Lobing is more prominent when two separate speakers are transmitting the same signal and they cross each other out on certain frequencies and was wondering if your noticing that effect with the center speaker back drivers conflicting on the front drivers.

Yes, I've played with the levels. If I turn the subs up movies are ok (not great) but music becomes boomy.
DefTech says the 8060's will go down to 20Hz, reality is they go down closer to 30Hz and drop off way to much at 20Hz to really be effective.
It could be my room that is the issue, so a sub in a different location might just be the ticket...I'll find out soon enough...

Wouldn't this be an issue of phasing between the speakers?

Yea that's what I would think also I'm wanting to play around with a sub to see if I would notice a difference

According to Wikipedia "Acoustic lobing refers to the radiation pattern of a combination of two or more loudspeaker drivers at a certain frequency, as seen looking at the speaker from its side. In most multi-way speakers, it is at the crossover frequency(ies) that the effects of lobing are of greatest concern, since this determines how well the speaker preserves the tonality of the original recorded content.[1]"

As always, more to learn...Over my head at the moment...Too much beer, and football is on...LOL

Hi Guys,

I am selling a pair of BP 2000TLs and a CLR-3000 (together or separaely). They are in great condition and priced reasonably.

Local pickup in central NJ. Please PM if interested.

Can any StudioMonitor 350 owners help me out? I just ordered a pair and am looking at stands. It looks like the Def Tech stands have holes in the top plates through which you can attach the speakers.

http://a248.e.akamai.net/pix.crutchfield.com/Manuals/735/735SMSTND.PDF

Are there already four holes in the bottom of the SM 350s?

I'm not interested in drilling holes in my new speakers, if not!

These stands are a bit pricey and don't have very good speaker management (only a couple of clips) so the ability to affix the speaker to the plate is the primary reason I'd be interested in them.

Anyone have any stands they like a lot? I found some Atlantic ones which rotate 45 degrees for about half the cost of the DT ones...

Thanks!

Sanus makes some wooden stands that the speaker will just sit on top of. As far as drilling holes in your speaker, I don't have a problem with that because I do exactly what DefTech would do. I buy the screw inserts and install them where I need them. Having a screw insert looks professional and may actually be a bonus when they are sold. Finding #8, #10, or 1/4" shouldn't be a problem. Lowes will have them for about 50 cents each for the brass ones.

Aaaaaaaaa, If this was remotely an issue bipolar speakers would never had hit the market. Using a DT tower for a center will give the same result as if a left or right etc., no "lobing". Now, the dialog my lose some directionality but given a large screen it might be very effective.
As mentioned before, several folks have used large BP series Definitive towers for centers with excellent results. The primary reason you don't see it or have more folks doing it is cost and form factor. I know if I had a full front false wall and an AT screen I would have three BP-7000SCs across the front. may be my next theater build.... :-)

Cheers

KJSmitty I can see the real world potential of using a tower but my greatest concern besides the lobing issue (and its most likely frequencies we wouldn't even notice) but by how James has the tower placed. With the rear drivers sound bouncing off the entertainment center, rear wall and behind the entertainment center. Placement is key obviously and if I could (and I had the chance) of placing a full size tower on top of my TV but there were far too many acoustical issues so I went with a LCR2002 hooked up to its own subwoofer (Prosub 1000) for sound from 40Hz-20kHz to match what my BP7001's have been set to for uniformity. Trust me another 7001 would've been much easier but again too many acoustical problems in my room.

Here is the current setup. I'll be replacing the pro center 2000 with a third bp8b. Quick question, as you can see the couch is near the back wall, should I wall mount the 450s high or maybe just one? Should I bring down the bpx I feel they are a bit high I could drop them maybe 6- 12 inches. Any input would be appreciated! I need to also install a door so I can isolate the room better.

Here is the front

Thanks for the info. I've seen the Sanus NF30s. They, like the Atlantic ones have a 6" x 6" top plate. Functional, but smaller than the speaker.

I have a 3 year old son and a small terrier type dog, so don't want to trust nothing but balance to keep my speakers on the stand. I suppose I could get some of that Quake Hold museum putty stuff and hope for the best.

I was really hoping the speakers would have some sort of threaded screw hole inserts already for mounting purposes. I've looked all over the web and can't find much more than stock pictures of these stands and not much about solid secure mounting options for the speakers. Surprising since they are so popular.

My ProCenter 2000 has two threaded inserts in the back for mounting purposes. Are you suggesting I install some in my SM 350s myself? Won't that affect warranty? What if I go too far and drill into the inner cavity of the speaker? Wouldn't that affect the sound?

Thanks!

Is wall mounting an option? That would eliminate the need for stands and make it safer for the little ones. I have mine sitting on stands, without any problems so far (knock on wood). If wall mount is out and you dont want to drill, maybe find some stands with a top plate that fits between the 350s little nub feet for a little extra 'staying' power and maybe add some industrial velcro. Another thing that will help standwise is a weighted or fillable stand to add weight.

Yep,
The center channel / speaker is probably one of the most experimented areas out of all. For me the big focus isn't on the large "woofer" section yet the mids and highs. However, I'm a complete fan of a center set up like yours or a powered DT CLR to facilitate a true full range center channel.
- For the majority of most movies the center channel is bombarded with near twice the "sounds" other channels are. That might not be the best way to articulate it yet the center speaker gets rode hard.. :-). I have two CLR3000s and I have often thought of running both vertically, bottom to bottom under my screen - possibly utilizing an additional two channel amp etc.. Like James above, the experimenting is half the fun.

Cheers

First thing I did to my SM55 was to put threaded inserts in them, but I have the proper jigs to ensure a level hole with an exact depth. Before I bought a jig, I used to just put masking tape around the drill bit to keep from drilling too deep. I have the DefTech CLR 3000 and the threaded inserts installed by DefTech go all the way through the cabinet, so I guess it won't have any noticeable affect on sound. I'd go with the museum putty before drilling holes for a speaker that is just going to sit on a stand. I drilled mine since they were going on articulating wall mounts. Even the 1/4-20 threaded insert will only require a 1/2" deep hole. You'll have to ask DefTech about the warranty. I would assume it will be OK since they suggest screwing speakers down for their stands. DefTech will generally ship just the drivers instead of swapping out the entire speaker.

The dimensions of the SM350 is only 7" x 10" so a 6" x 6" base should be good enough for them. It is going to be hard to get a base that matches the speaker exactly. You just want something with a hollow pedestal that can be filled with sand or shot.

That's great info guys!

Seems easy enough to put some inserts in myself. Even if the top plate on the stands don't have holes I can just drill some, then use that as a template for the inserts in the bottom of the SM350.

Probably sandwich some good rubber in between to dampen any vibrations and I'd be all set.

Good ideas.

Thanks much!

Hey all, This thread is packed with some amazing info, and I have a questions. I was leaning towards a Klipsch 7.1 system for my basement non-dedicated theater. I was going to go for WF35 fronts, WS-24 Rears, in-wall surrounds, and a WC-24 center. However, in the classifieds here I just came across this local listing for a DefTech system: http://www.avsforum.com/t/1453337/denon-def-tech-equipment. I know there may be some bias, but which system would be better? I would add some in-wall surrounds to that system. Until recently, I was completely unfamiliar with DefTech. Lastly, what would be a fair price?

Thanks!

If its not going to be a dedicated theater room that would be a pretty good set up and will sound great as long as the receiver is properly calibrated. As far as a fair price I would have to look up current prices for all that equipment
