HiVi suggests a crossover freq of greater than 1800hz. Usually, rule of thumb is to have the crossover frequency one half to one full octave above/below the "cut off" frequency point. So around 3khz-4khz would be better...not too good for that woofer combination.

Those woofers look VERY much like the 7" woofers offered by Styrke. I wonder if they are related at all...

Anyway, unless you are dead set on designing the whole speaker for yourself and are ready for a lot of trial and error, $200 for the drivers and NO crossover parts and not even a crossover design you'd be a lot better off getting a kit from any of the number of reputable DIY dealers. But kudos to you if you want to go it all alone, and good luck. :emoji_thumbsup:

I've seen it posted that you really can't trust the HiVi FR graphs. Almost all the speakers I've seen that use that tweeter have used it in a 3-way. Sorry I can't remember examples, but it has been a few years since I've looked at HiVi drivers.

As Dan says, you'll want to cross at least one octave higher than Fs, which means 3.2KHz at a minimum. Some of the Morel tweeters can cross low, though.

The North Creek and Acoustic Elegance (formerly Stryke) drivers are not the same. The SA-071 is unshielded, and has a bigger magnet, a stamped frame, and a woven-glass-fiber dustcap as well as the cone. The woven glass fiber dustcap helps control resonance issues that some drivers have with their dustcaps.

Thanks Rory,

I knew they weren't the same driver as one is 7.5" and the other is 7". Back when I bought my Stryke MTM kits John was supposed to be getting shielding cups soon. That was a year ago...I guess I was just hoping I could get shielded drivers soon...


That's ok, I decided my solution will just be to get a projector instead. :D

Mike,

At one time I was going to build my own speakers too...I'll see if I can't recall some of the driver combinations I was going to use and let you see what you think. I'm no expert so I have zero crossover designs done for any of them...but it could get you off to a good start.

Do yourself a favour and get a kit.

Reading your starting post, you clearly have no idea of the amount of work needed to get a good sounding pair of 2-ways out of those drivers.

I´m sure the drivers are as good or better than the pricetag would suggest and supposedly better than any drivers fitted in a sub400$ pair, but it still ís not worth it. To much knowlegde/effort needed.

Sorry :frowning:
