Ditto, if you're comparing Subs with the same size drivers and have the physical space for ported, always opt for it.
Since they will normally play louder and lower than their sealed counterpart, they will give you more flexibility, not to mention versatility if you ever need to move them to a larger space.

Most of the negatives surrounding ported subs are really just not valid anymore with today's subs.

Very long time Definitive owner here. A few months ago I replaced my ancient B&K Reference 20 processor with a Marantz SR7010 receiver with Dolby Atmos 7.1.4 capability. I'm looking to do four ceiling Atmos speakers in the not too distant future. I've read through 27 of the 78 pages in the "Best in ceiling speakers for Atmos?" thread and so far there has been no talk from Definitive owners so I thought I'd ask for thoughts over here on the Definitive DT and DI series in-ceiling speakers. Also, I'd be curious to know if anyone here has tried an Atmos setup with bipolar side and back surrounds. (No, I haven't had time to read back very far in this thread yet to see if these topics have already been discussed.)

Here is my current setup.
BP2000 mains.
CLR2000 center.
BPX side surrounds.
Marantz SR7010. Using as a pre-amp for the ear level speakers. The receiver amps will power the Atmos speakers, though.
B&K 2-channel amp for the mains.
B&K 6-channel amp for the center and surrounds.

The B&K Reference 20 was a 5.1 processor. After many months of watching eBay, I recently picked up a second mint pair of BPX speakers to go to 7 channels, but I haven't hooked them up yet. It wasn't until the day after I purchased those that I really started to think through and research future upgrades and it occurred to me that maybe bipolars aren't the best option for the new object oriented 3-D audio formats. Perhaps I should have sold my BPX speakers and picked up four Mythos surrounds instead. Now that I have them, I figure I might as well see how Atmos sounds with bipolar surrounds before I think about selling them.

I currently have a suspended ceiling, but I'm looking to replace that with drywall sometime in the next few months. That's when I'll do the Atmos speakers. I'm hoping to take the ceiling up to 8', but there are some complicating issues that may force me to stay at the height of the current ceiling, which is about 7' 9". Reading through the Dolby Atmos white paper and the ceiling speaker thread, it's clear that I need speakers with at least 90° dispersion. The DT and DI series in-ceiling speakers all say they have wide dispersion characteristics, but Definitive doesn't give any numbers on their website. Has anyone used them for Atmos? I'd also be interested to hear what anyone using them as standard surrounds thinks of them. I'd probably go with 6.5" or 8" coaxials. I want to cross them over at 80 HZ, so certainly nothing smaller. For timbre matching, sticking with Definitive for the Atmos speakers seems like the obvious way to go if their dispersion characteristics are suitable.

If you have Def Tech in-ceilings, I'd also be interested to know if you are using them with or without a backer box. Definitive's owner's manuals say they make backer boxes, but they don't have any info about them on their website. Maybe they perform great without a box, but it sure seems like getting decent mid-bass response would be tough without an enclosure. (Admittedly, I have no experience with in-wall or in-ceiling speakers.) Since I'm taking the old suspended ceiling down, I could construct custom boxes if I can get a recommendation on volume and damping material out of Definitive.

Lots of people in the ceiling speaker thread are raving about how great the Atlantic Technology IC-6OBA-S speaker is for Atmos. Particularly with an 8' or lower ceiling such as mine. They are saying the unique dual dipolar tweeter arrangement really reduces hotspotting issues. AT is marketing this as specifically designed for Atmos use.



That's got me wondering how the DT6.5STR with it's dual tweeter design would work for Atmos. (Obviously there is a big difference between bipolar tweeters and dipolar tweeters.) The DT6.5STR must have extra wide high frequency dispersion along the axis of the tweeters. It seems to be switchable between stereo mode where left and right are fed to a single speaker in a distributed audio system or bipolar surround mode according to the webpage. The manual doesn't have any detail on this.



Also, I'd like to chime in on the standalone sub issue. I've never felt the need for a standalone sub with my BP2000s. I haven't spent any time listening to Definitive's newer lines so I don't know how the sub section in the 9080s compares to the 15" subs in the BP2000s. I can say that I recently went to a special SVS event at ListenUp in Denver and I don't think anything short of the Ultra series would add anything to my system and I just don't feel like I need more low end in my mid-sized room. Obviously if you are going with something smaller than top of the line towers then you'll want to consider a standalone sub or two and I highly recommend SVS. Even the least expensive SB-1000 they had set up with Prime satellites absolutely rocked. The 13" and 16" Ultra series subs can go toe to toe with anything out there.

While bi-poles may not be recommended, there's no reason to swap to mono-poles, I have all bi-poles for my entire ear level layer, and from what I've heard, (with my system and others) if your used to a system with bi-poles, you won't notice a problem or be disappointed in any way, compared to mono-poles with the new immersive formats.

While I've always had a separate sub to go with my front BP2000's, there really is a difference, esp if you move to multiple subs or like running your Fronts full range.
But there really is no comparison between the sub sections in the newer models and the BP2000's, IMO the 2000, 2002, 3000, 7000, 7001 or 7002, would be the only Supertowers I'd consider to be up to the task of actually doing a decent job of bass reproduction in a "no Sub" system.

I have the di6.5 r without backer boxes. They sound good in my opinion. Also use 4 bpxs and the most important part is getting them low for atmos.

Depends on the size of your room. I have a medium size room but it's open to the kitchen and dining room and I have a PB-1000 and it rocks the place. You might need or what more and the PB-2000 is the better choice then.

If medium yes. Enclosed or open to other rooms? If it were me I'd go with 2 PB-1000 subs. Dual PB-1000 subs in the way I'd go.

I would add if your budget allows it, two subs will even out the bass response in your room much better than one. Not necessarily more bass but more impact and not as boomy as a single sub can occasionally do depending where placed.

Really never a reason to go svs unless you find a used one for a steal.
Really? I never heard of Hsu before. Wonder where can i go to listen to one

19 x 16 "game room", so I take it, it's a stand alone room with a door...
If so either 2 PB1000 or any of the 2000 series.

Honestly, if you're going to do one at a time, or can afford it up front, I'd go to the 2000 series, just a little extra cash now, for much more flexibility in the future, esp the PC series, smaller footprint and they can even be laid in their side for even more placement options.

But, don't forget... PB cabinets are "Large", if space and placement are of any concern, build a cardboard box to the proper dimensions, it will really help to realise the actual size of them.

Dr Hsu was around before SVS began. SVS started from a member that posted on Home Theater Forum years ago I believe in the late 1990's. They only made cylindrical subs then. Quick sales and happy customers helped them expand quickly.

Yeah you can always hook up 2 subs to a receiver. Just a Y splitter I think it's called and 2 RCA cables to each sub. Nice and easy.

Ditto, separation between ear and height layers is much more important that the bi-pole - mono-pole issue.
