Re: DIY Corner Horn Recommendation

Greets!

OK, I have specs for a number of RS drivers, but not the 40-1034, though if they are similar spec wise with the 12" 40-1035, they aren't suitable for corner loading except in an aperiodic cab and due to their high Qts won't be very 'fast/tight' in any other alignment. Regardless, AFAIK there's no proven design using this driver.

As for the 40-1219 piezo horn, they are fine for certain apps when properly implemented, but it's going to be tough blending it to a 12" with any kind of acceptable sound quality (SQ). Factor in that neither of these drivers have anywhere near enough efficiency..........

All things considered, I guess the easiest solution for you is to buy whichever vented Pi speaker kit suits your needs/wallet and build a triangular or trapezoidal cab based on the plans net volume (Vb) and load the corner same as GregB's speakers. Tuning may be different than the kit calls for, so some experimentation may be required to get the best in-room results. Another kit option is the Adire HE12.1.

Another possibility is to mount the HE12.1 or Pi kit components (or similar) into this style corner horn (see link) though actual dims may need to be different, but such details can be worked out later if you decide to go this route. At a more advanced level would be to adapt a Fostex or similar back loaded horn (BLH) for corner loading.
