Hi fascinated by the possibilities offered by the Dayton Epique 7" Wide Range E180HE-44 subwoofer.
Anybody got any builds that uses this in a 2 way?
Partial to a horn tweeter or waveguided tweeter.
A minimalist crossover would also be ideal.
Or is this purely for subwoofer use?
Any leads or help would be appreciated.
Thanks!

You have a high excursion driver with a smaller diameter. This pushes the crossover frequency up relative to the 'average' DIY waveguide/CD 2-way. Dome should be possible, preferably not a smaller dome.
Greets!
Well, to me 'minimalist' means 1st order, so backing up from a ~5040 Hz? peak = 5040/2^4 = ~315 Hz XO, so one of those small 'FR' drivers or large 3/4" throat DIY conical horns.

Don’t be fooled by the tone sweep response curve……get that driver pumping with that high walled surround and the cone to surround profile will be VERY DIFFERENT at 1-2khz as will the actual response. The Q of that driver is also pretty high so take that into account as a negative in a ported alignment.
You don’t mention if this is for a near field listening system either…..listening to a CD in a horn in the near isn’t a good time IMO and you don’t need the directivity.

Not much difference in a 7" or a 5" wide woofer IMHO in terms of matching for a 2-way system. The dual magnet Peerless and SS ring radiators and domes should accommodate it reasonably well, with a crossover between 2kHz and 3 kHz if perhaps with some limited dynamic range. Unfortunately I think some of these are going out of manufacture.
This type of compromise is rather common in commercial and DIY designs AFAIK.

Times change I guess, but conical, and especially parabolic (300 Hz in my case) always sounded good up close with Altec drivers.........
I would build a WAW. The efficiency of a horn would be wasted on that woofer. A WAW would let the woofer do what it does best which is reproducing low frequencies, you might even be able to do a first order XO around 4-800Hz with a 3" wideband as the tweeter. That would be an interesting project.
If you like the sound of horns then go with at least a 10" pro driver and build something like an econowave.
