Two subwoofers??

Sean, design concepts aside, what did you think after listening to the Bag End Infra-sub?

As for my comment about an 8 inch woofer bottoming out around 30Hz? I stand by it. In my experience and reading, it appears that there are very few if any 8 inch drivers or even 10 inch drivers that can adequately reproduce frequencies below 30Hz around the price break of perhaps $1500 or less. Jeepers, it appears that there are too many 18 inch subs that can't go much below 30Hz.

As I've stated elsewhere, the size of driver seems to become less important in subwoofers at more expensive price breaks.

I'm certainly not going to pretend to understand how a subwoofer 'should' or 'shouldn't' be designed because I don't know and don't care. But as with manufacturing most anything, manufacturing a subwoofer to do what it really ought to do is probably more of an art than a science. And the execution and the whole is hopefully greater than the sum of it's parts.

By all means, correct me if I am wrong.

With that said, I will say again, that yes, the Bag End has a few flaws, (which component doesn't?) but in my room two years ago with my configuration, it certainly sounded impressive, just as some reviewers had said it would.

But again, Sean, I'd be really interested to know how you think how the Bag End sounds.

Bottom line ? I like the Bag End. Like anything else though, you have to play with the installation to get best performance from it. Sean

The advantage of using two subs is that you can place them next to each speaker which should allow you to cross them over at a higher frequency then if you use just one. Not using the A+B summing will let them run 3dB lower than one sub alone. Looks like a nice option albeit at twice the cost. Question Sean, you state that the Bag End resonates at 70Hz. Is a user OK as long as he crosses over below this frequency?

I'm assuming that you are looking at 2 subs for a home theater setup. For a home theater setup, you would want to get a larger sub like a 15" or an 18" for more slam/boom in crashes and explosions. These larger cones tend to be more sloppy and slow. (the larger the surface area, the slower it is going to move and stop). If you are looking for a sub for a musical setup, the smaller the driver the better. (most decent speakers do not need a sub for music in the first place. If you have the right room, the right setup, and a decent 2/3/4 way speaker, you will get a more true-to-life sound than emphasizing the bottom end. For example, read reviews of the famous Revel M20 small monitors, the reviewers indicate that they are not missing anything and prefer the sound of the M20's without a sub). If you think you still need a sub, try to audition one that has multiple small drivers which will be faster and more accurate than that of a larger more sloopy driver setup.

Search4tas must be smokin something to think he's not given up a thing with his small 2-way M20 monitors. If that was the case, Revel probably never would have made the Studios or Salons which in my opinion are way better than the M20's. And the stuidos and salons prices which is 5 to 8 X's the cost of the M20's would certainly make us believe that at least Revel thinks the other speakers to be superior to the M20's. Especially in the lower regions.

Search4tas also misinterprets the reviews of the M20's. The reveiw in Stereophile says no such thing. Only that the M20's sound bigger than they are.

S4T's comments about the subs being sloppy, slow, crash, boom, bang are almost as obsurd as his other comments. There are good and bad subwoofers big and small. I've heard as many smaller subwoofers with no musicality as I have heard larger subs.
