Great looking design @EricH and @mtg90 . First the HTM series and now the Titan. Looks like you guys have been busy during the holidays.

That looks awesome, what a monster. Price isn't too bad either. Downside is it requires massive gobs and gobs of power to get reference (something like 32W).

Really cool looking design. I'm glad I don't have the space for them, or I might be having HTM-12 buyer's remorse before I've even finished the build!

In this situation its a good idea to take nearfield measurements and merge them with the farfield. That will give a more realistic example of the extension. Or even display them independently.
Thanks, yeah I know I actually cannot remember why I did not just do that.

In a 3cuft sealed enclosure it will have an f3 of around 70hz.

Low Fs = heavy cone, heavy cone /= pro driver.

There is no cheating physics, I'd say it's pretty much impossible to get a 15" or even an 18" with 95+ sensitivity and an Fs in the low 20's. Even the TC sounds Pro 5100 only had an Fs around 30hz. It might be possible for a 21" or more likely a 24" to achieve that but you are going to be looking at a massive ported box if you are expecting even 90+ dB sensitivity down to 20hz.

The only way you get these pro drivers to have a flat response down to around 20hz in a reasonable sized ported box is to use DSP to boost the low end.

Yea that explains why you don't see drivers like that for sale. How does JTR get an 18" at 100db sensitivity to be tuned to 20hz ... in a passive sub? Just curious how it's possible.

I'll take three please
I bet you could fit a nice 24" or larger sub driver just beneath that 15" to make it more Titan(ic)

You can tune the drivers to 20hz that does not mean they are flat down to 20hz without EQ, the Cap 118HT is not passive.

"The Captivator 118HT is a bass reflex subwoofer with a 18″ driver and a 700 watts amplifier is equipped with a full digital sound processor that has been optimized to the smoothest frequency response and highest possible output with minimal distortions."

I think 3 of these are going into my wall, I built JBL 3731 clones a while ago and this will be a properly designed version of it. I will use the sealed cabs though as I don't need below 70hz with speakers since I have 14 ported 18s.

Also with a 40hz crossover it will handle 1000w without the woofer exceeding xmax and 2000w peaks with an 80hz crossover without exceeding xmax.

I gotta say.. Max is the most incredible sub I've ver heard..I'm installing my second one this weekend. Super glad the design is getting some love.

Really exciting speaker design. Seems especially apt with all the chit chat about mid bass on the forums these days.

Any chance the Titan-615 will be sold separately? I might be thinking about them for a couple of MBMs. Can you share a price estimate?

They were part of the samples I got years ago in the big SEOS thread.

When the SEOS-12 was finally made with plastic I was told I had to use a small shipping container to get them here versus shipping 6 or 7 individual pallets. Well there was a lot of extra room, so I started looking around for things we could try out that could be shipped in the same container.

Samples were sent here, Bwaslo and I tested a bunch of horns/waveguides one weekend 5 years ago, and I ordered a decent number of the good smaller ones just in case they could be used for something. I saw these big 2 way horns and decided to order about 25 samples just for the heck of it. I showed them to Bwaslo and MTG90. We talked about them years ago, but back then didn't really think about making big speakers. Heck, the Fusion-12 was "huge".

Last year MTG90 stopped by when he was near Cincinnati and as we were looking through the shop I said "Maybe we should go ahead and use these for something." He agreed, and the Titan was born!

A lot of cases you either choose sensitivity or your choose low frequency, it's often give or take. For example raise the tune and give up a little on the bottom for increased efficiency in design phase, or try to maximize how low it will play and give up efficiency.

Personally I believe it's a huge mistake to give up efficiency or concern yourself with chasing very low bass in soeakers. It's generally a much better idea to let your subwoofer be a subwoofer and your speaker be a speaker. Bass management is a good thing not a bad thing and everyone should use it. The best place for bass is not always the same as the best place for your speakers, and it's very room dependent. There's a lot of ignorance and misinformation on forums like avs that make it seem like it's good to get a speaker with uber low end capability. That's dead wrong. There's at least 20 serious problems introduced trying to chase that fairy tale demon and it's unlikely that more than a special few people could actually pull it off in a manner where it was better and not worse.
