Some people will drive it off of a single channel and others (like Ricci) will drive it off of 2 channels-so the flexability of connectors is left to the end user.

I used a little $10 allen ratchet to great effect because all of the driver and hatch screws I used are allen hex.

Ricci, which panels weren't pre drilled and about how many holes did you have to drill yourself? Thanks for all the info so far, looking forward to hearing your impressions.

This is a deep extending subwoofer not a little MBM. If you were thinking of running it up to 150-200hz I'd look at something else for that job.

In Tom's example in the paper, he compares the same driver in the same size boxes, one vented and one a tapped horn. With the same power, the SPL is more or less equal but, because of the horn loading, cone excursion is less for the TH. When you run them both up to Xmax, the TH puts out about 10dB more but it also needs about 10x the power to do it. So Hoffman's law isn't really dead with these critters but it does get beat up a little.

I've read it before. It never really hit me but the paper does seem to be down playing the pay-off in efficiency for the TH, but the decreased excursion demands on the driver allow it to accept more power and thus put out more sound before hitting it's limits. This is confusing to me. Usually the extreme efficiency is what is touted. Really it's 2 different ways to skin a cat both allowing the driver to put out more sound with less effort (displacement).

The DTS10 sounds fantastic with music. I've thrown metal, country, blues, big band(Gordon Goodwin Big Phat Band, the best band and recorded incredibly well), electronic dance, classical, pop, as well as movies like Transformers, Master and Commmander, Spider Man 2, Open Range, etc and it reproduces it all incredibly well. Our demo room is set up with Crestron control and a custom switcher Ivan designed and built which allows us to instantly switch between any of our tops or subs in almost any combination. The DTS10 has more punch, goes lower than the DTS20 or the TH50. It really is a very nice combination of extremely low extension with punch. We regularly hear from folks that upon purchasing our products they spent hours listening to their recording collection hearing details like they had never heard before.

I don't know why they did such a comparison, when the DST-10 will trounce any LLT of the same size, according to my modeling and according to Brandon, who noted that the DTS-10 is 10 dB more efficient than his LLT.

despite his many posts, there were only about five or six people, who had much sympathy his posts. many ignored him. many thought he had an agenda. many tried to make him look bad because he hadn't built any big subwoofers. however, he never gave up on posting what he had concluded was the truth.

not too long ago, he posted a thread about the inherenent deficiency of modern spl meters to capture the instantaneous peaks and dips that are so important for recreating life-like sound. but data presented by other members drove him back from his original claim. eventually, he was forced to conceed spl meters are fulling accurate, just to end the arguing.

this guy would also talk about how much spl is actually required for uncompressed content. when he would present plots made in audacity and then calculate driver efficiency and amplifier needs, the results usually exceeded what most people have (systems capable of uncompressed response into the 120db's). as a result, most folks would tell him he was wrong, ignore him, flame him with comments such as "nobody would ever listen that loud", or roll their eyes. however, there were always a few people around that had sympathy for his posts and five or six who actually agreed. despite this, the weight of the forum was always on his shoulders, never a majority in his favor.

tom danley recently made a post that reads like something that other guy would have written:

http://www.avsforum.com/avs-vb/showp...&postcount=534

i suspect that tom's post (and the reviews that will follow his gift to our community) will give many members who disagreed with that other guy pause, because unlike the other guy who has no credibility, tom's cannot be questioned.

i just can't remember who that other guy was. none the less, it is great to see tom's post because, hopefully, these issues will now be discussed in a more balanced fashion.

As Noah said, the DTS-10 will trounce ANY single driver ported sub in every category.

Josh will verify this fact.

The interesting match up is MKT's system, IMO. X-max is irrelevant. He NEVER reaches X-max even when pegging the RS meter and the efficiency gap is narrowed in co-locating 8-18s while power handling is way higher and BW is an octave lower.

There still isnt a pro audio driver that does what the Mal-x does in a normal box.

This thread is more about Danley's designs and less about the driver being pro audio. I think its incredible he can get down below 20Hz with these types of numbers.

Or are we to the point that certain designs can have 1 watt graphs posted from the manufacturer and then we decide that we can just add 33 dB to this output for a 2000 watt signal and call it a day ?

Horns in the pro sound shootout from a couple of years ago:


That's 1600W at 10 meters. Scale that to 1M.

When that manufacturer is Tom Danley... yes, we're at that point.
