DIY Dayton 15" HF Sealed - Page 2

I was under the impression that the HF's had much better sound quality.
Since I will be running 4 in a sealed 2600cu/ft room I think I will still stick with the HF's. I don't think they will ever hit their limits.

Box size, the persons room, power etc all play a big part. With a proper box size and proper wattage, theres no way the titanic will sound "boomy" I'm afraid, unless they made a crappy box or had some other problems with their systems.
But take info for what it is. I've had both in the same box, in the same room, with the same power AND know what I'm doing. These 2 subs were my 28 and 29'th sub I've built.

To be honest, I wish the shiva, tempest or SDX were still around. I'd take any of those offerings over anything available right now in a 15" (other than maybe a lms-r)

I recommend supporting, and clamping another piece of wood on the outside of the saw to prevent movement to consistently get 90 degree cuts.

Let me preface by saying I don't care for 15" in a sub for the average home living room/HT space, just totally unnecessary IMHO. The drivers I will speak of are the 12" versions of all the drivers discussed. Now, having said that:

Having heard BOTH the HF & Titanic, I agree w/deathinc. The HF/HO, while not the same amount of output, DO sound noticebly better for clarity & control when compared with the Titanic. This is the reason I bought my first HF instead of the Titanic. And still have it. The HO (which I also purchased), certainly is no slouch either and why I bought one also.

And as for "proof" , this is the internet, anyone can say anything and come off sounding knowledgeable. However, in my case, I literally live less than 30 minutes from Parts Express in Ohio and am a frequent 'visitor' there. So I have an idea of just how their drivers sound.

Now, for the horrible advice you gave for going with a 300 watt amp instead of a 500 watt amp because a 500 watt amp wouldn't be turned up past 1/2 way, is just ludicrous. I am running 500 watt plate amp with the HF (and HO as well) and it is absolutely perfect. Ample headroom for those times when we want the audio cranked up, and subtle, but noticeable at 'normal' and lower volumes. The HF just purrs thru it and we couldn't be happier.

The Titanic has a well deserved reputation, this is not arguable. For sheer output, I too would recommend the Titanic. But for actual SQ, regardless of the output, I'll stick to (and highly recommend) the HF or the HO.

one argument would go that transient response is based on le/re.

the triple shorting rings in the hf gives it a relatively low value of 0.30.

the single ring in the titanic gives it a relatively high value of 0.82.

lower le/re tends to correlate with a more linear le/re too.

at least that is how one argument would go.

Pretty much but also that someone thinking the HO/HF is going to have way better SQ, is silly as long as they are in their proper enclosures. I would really only compare the 2 if the titanic was on sale to begin with. Solen.ca has them for $216 CDN, which is a pretty good deal vs the $179 for the HO.

I've built 3 boxes for the HO, 2 for the HF's and 2 for the titanics and had the HO's and titanic's in the same room, with the same amp, in the same box, in the exact same position and had 5 people comparing as like I said, they are a gift and I wanted the best SQ and output possible between the 2. They difference is subtle at any volume not beging to take each driver to their limits. The HO's were starting to make mechanical noises with 1/2 on the 500 watt amp playing at well below reference in their 3CF boxes. Both drivers played within their limits were great, the titanic just offered more as far as HT is concerned.
Granted that is not an idea size for the Titanic either. They played best in the 5 CF box I had in my garage.
