Definitive Technology Promonitor 1000 speakers sound really sweet, especially for the price. I picked up a pair used, but in new condition, and they sound fantastic.
Your curtains won't kill any bass standing waves unless they are made out of plutonium. They aren't dense enough.

They won't kill but they will help.

Sure they will help.

They'll help a teensy bit.

At best they'll clean up some lower mids.

That's better than nothing. I would imagine that is why most every movie theater I have seen has the bunched up curtain walls.

Wrong. I'm being a dick but read up about this stuff. Movie theaters have bunched up curtains for a number of reasons, and probably the primary one is for a traditional look. Movie theaters are evolved play theaters right? They also have curtains and in-wall batting to suck up highs to make the room dead.

Heavy fabric will suck up a lot of highs, some upper mids, a little mids, and almost no low mids or bass.

Adding curtains could make bass playback sound clearer because you can hear upper harmonics, picking/slapping noise etc more clearly, less "wash" from highs overpowering your perception etc but adding curtains won't make a sub appreciably flatter.

the effectiveness of an absorber is often related to the wavelengths of the frequencies it is absorbing.

high frequency waves are short.

low frequency are very long.

that's why you hear thump thump from cars and other theatres, but rarely the highs.

I've got a Shiva (RIP Adire) sonotube in my basement. Has worked well for the last 8 years or so.

I have a bunch of 8-12 sonotubes in my shed taking up space if anyone local is looking for some for a sub project.

Also have an NHT 1259 clone (same motor and voice coil but higher Re) in a 10 inch that I was going to use for a project if anyone wants to build a good cheap sonotube for a small HT setup.

I don't want to ship this ****, so you gotta pick 'em up.

Well I meant sound in general, not just low frequency.

I got the new Star Trek in Blu-Ray for Christmas and played that yesterday. The LFEs are fantastic. When the ships go into warp they make this fast broad spectrum transient thump-pop sound. The sub hits those hard and fast. The movie is full of good LFEs in general.

I just bought a set of Def Tech BP6B used (in pristine condition) from a local audiophile guy I found online. He had upgraded to some used Martin Logan Quest electrostatic drives and thus was unloading his 'old' speakers. He Played the MLs for me and of course they sound fantastic. The sound stage is pretty spread out (not much location info) but the mid-range sound quality on vocals and piano is really, really good. They are also really, really expensive, much too expensive for my blood.

Normally I build speakers myself but used Def Techs in good condition are such a good value it is hard to build anything as good for less money.

I've watched Star Trek probably 4 times since I got my speakers 2 or 3 weeks ago. I don't even have a sub yet, but just with the weak bass provided by my front channels, the sound is still amazing. Some of the best sounds in any movie I have seen.

I watched public enemies in blu ray the other day, and I gotta say the gun sounds were fantastic, like better than most movies lol.
