I built a Stryke HE 15 dual sub with 6 15" passive speakers 5-6 years ago. I think I bought the box and speakers from John Janowitz out of Green Bay. The box is massive and must weigh 250+ pounds. I feed it with a Crown K2 amp and I believe it's wired at 2 ohm's and delivers between 3-4,000 watts.

Once a year I make sure all the screws on all 8 speakers are tight.


How does this sub compare to the new ones out? It still rocks my house and I see no need to replace it unless there are newer drivers out that are a lot better and resonable in price. I use it just for H.T. I use a Paradigm Servo 15when I just listen to music.


Thanks a lot.

Do you have any REW charts to show its db output from 10hz+ that would be a good way to baseline it against a lot of the current DIY subs being made.

John is still pretty active on these forums. He may have the specs still. If you know their exact model numbers you could do a search on google and probably find the specs.

How does it compare??? two 15" drivers and a K2 amp is good no matter when you bought it

John makes incredible speakers, drivers now so Im sure its still great.

I still have one of the HE 15s your talkin about. I had 2 at one time in a dual opposing configuration with 4 passive radiators it definitely had some output!

My box is 36x24x22, has 6 15" passive radiators and two 15" HE 15 drivers. When I bought these drivers, I believe they were considered about as good as you can get. This thing still rocks the house with a Crown K2 amp and a Behringer Feedback Destroyer Pro for e.q.


I wonder if the 2 drivers and 6 passive radiators are still air tight. How would I measure that.


If I remember right, John J. said this dual HE 15 had the power of 6-7 Paradigm Servo 15's corner loaded. I wonder how it compares top the best subwoofers of today?

Your sub would still be in the top 1% (or so) of all the commercial HT offerings. I would be surprised if you have any headroom problems at all. To "better' your sub, you would have to spend a significant amount of money.

I have two of them myself. If you're really disappointed your house is still standing, I suppose you could find some way to upgrade.

Speaking of which, I am in the process of moving mine into some ported enclosures. Anyone wants any of the PRs, they are available for the cost of shipping alone.
