CLamshelling the drivers with a piece of wood between is a-ok.  No problems there.

ANd the WO's that I have built full size(36 x 36) outperform the 24" ones in the lower frequencies, about everything else is comparable though.  The 36 x 36 just has more impact the further down you go.  the 24 will do it, but compared to the 36 it sounds kinda hollow.  

The only way I can describe it is kinda like ice cream.  The 36 inch version is like nice cold icecream, whereas the 24 is kinda melty in the lows.  but they still taste way better than other boxes. lol.

[quote author=HT-EXT  link=1134492004/0#2 date=1134493552]THANKS JRock the info helps. Do you have any suggestions for subs. I would like to keep the price between $40 to a $100 each. I like some of the Daytons but unsure of the ideal numbers for the WO36 enclosure (Fs/Vas/Xmax/Qts).  











 THANKS [/quote]

the wo works with almost any good subwoofer, the wo32 is more picky.get 4 good 10s and get ready for some serious bass. in fact if you have alsmost $400 to spend, buy 2 of steves/decwares 10" drivers.

[quote author=HT-EXT  link=1134492004/0#4 date=1134496063]Appreciate the info 60. Do you think two of Steve's 10" would out perform four Classic Daytons or four Series II. I am looking at both but when I start an experiment it is nice to start on a budget(Classic Daytons) and then move up from that point if needed. Would Steve's 10" make a huge difference for the cash?     THANKS [/quote]

steve KNOWS audio. i have never actually heard  his drivers, but i bet they are much better (dryer, faster, deeper) than most subs available.so i suppose it depends what you want. you want the best sound possible? go with the decwares, you want to save money and still sound good , try something else.personally i dont see subwoofers as an experiment, i decide what it is i want and then go get it. the wo is a fantastic desighn that needs NO MODIFICATION to produse tons of quality bass.

out perform? you want volume or quality? what kind of 'performance' are you after?
either way probably yes.

OH YEAH 60 can I put the woofers in opposite chambers with the speaker baffle between them instead of directly clamshelling them together.

[quote author=HT-EXT  link=1134492004/0#8 date=1134502059]I know this is going to sound crazy but I plan on using the WO36 in conjunction with my HWK15s to try and get the ultimate blend of bass mostly for Home Theater. Of course music and entertaining friends will surely be in the picture. I was looking for something with high SPL and low bass to put directly in front me that could be mistaken for furniture. My HWK15s are locate behind me and have tendency to be overwhelming. I looking to match or come close to their performance.

in that case i would say your going down the wrong road, i built a h.w. with 2 x older 15" jbls, it is amazing. i have no doubt that a 'working' h.w.has the ability to make people litterally 'jump out of their seats' with IMPACT.but its an odd desighn and i guess its possible that a small mistake in constuction or driver selection / orientation can make it not work. before you spend more money try unplugging one of your hws, and experiment with just 1 in the room, try several different locations within the room. if your sub bass is already overwhelming adding another subwoofer will just compound your problem.

Big Air what do you mean by IMHO calmshelling because I am a stup. Also how many Quatros do you use and what amp? What do you consider to be a low fs for a 10" woofer?THANKS

I found this on computerhope.com one day. I love the name. If you have a computer, you hope it works.
Check it out.  :)

Concrete makes heavy bass really harsh. You might need to use some bass traps to help control reflections and standing waves.

It never hurts to play around with phasing, especially if you have bass to spare.

[quote author=HT-EXT  link=1134492004/15#16 date=1134574735]My main problem when it comes to bass enclosures is how loud will it play........ Do high output(SPL) enclosures have better low bass, speed , response, room loading even at moderate volumes. I know SPL is not everything but I have a hard time leaving it out.  All info gladly appreciated. [/quote]
Well ..... that can be a problem, all right. I have seen the oppostite more often than not. In order to get really high SPL, many concessions are made in sound quality. For instance, most cabinet designs that support the lowest bass are somewhat less efficient in the rest of the range they work in.

As far as speed, I think of a compression driver front horn loaded cabinet, because the lowest frequencies are hitting you at the same time as the rest of the spectrum and there is no group delay at all. All ported cabinets show some group delay, which varies as the frequency changes, usually the lower the frequency the more it lags behind the mid-bass frequencies. That's why you have probably heard that sealed cabinets are cleaner and more dynamic, no delay.

Room loading can change drastically just angling a cabinet a few degrees or moving it a few inches. Where you place your subwoofer cabinet probably has more bearing on how your room is loaded than any other single factor. Adding a second source of pressure with another HWK, will not necessarily make the sound any better, but it can certainly alter the location and intensity of nulls and voids in the sound caused by standing waves. Adding, yet another with a WO complicates things even more.

Talking about response, the most perfectly flat responding driver can be made very uneven, tone-wise by placing it into the wrong cabinet and the most perfect cabinet/driver combo can have many peaks in the response in a certain room or room placement.

Another response that comes to mind is transient response and many large Xmax drivers don't do well following rapidly changing waveforms common to music. Of course with Home Theater, many people don't take clarity and sound quality seriously and a large quanty of bass becomes the quality they are looking for. As someone who watches a movie almost everyday over a fairly clean system, I can tell you that many movies don't have clean, well defined low frequency content to start with. Getting those lows off the disk and over to your listening area is not a simple game to play.

Before you get too crazy with adding more and more cabinets in the room, maybe you should try just one House Wrecker iso loaded with 4 drivers and enough power to really drive the thing, then move it around some and try different locations.

No problem BigAir I'm the stup around here but I'm learning. What was the reason you went with 2 Quatros and what is your main use for the WO? Also what size did you settle with on the WO? What other set ups and speakers have you tried?

THANKS BigAir for the reply. I was curious to your WO's performance. I take it you are using the WO for car audio. Usually with car audio SPL contest are common. Have you ever check to see what the WO is putting out. Can you give me an idea of the SPL and how low you think your set up can go? I am very interested in the Quatro speakers and would like to have an idea of their performance. THANKS
