Rated 5 out of 5 by from Great driverI have been using these for a few years now, compared to the EV & University that these have replaced they are tough. YOU MUST use a 300 Hz high pass filter ahead of your amp if you want to appreciate their full potential, or you will blow some out. I only wish they also had a 15 watt tap!

Rated 5 out of 5 by from A GREAT Leslie Replacement Driver...I'm so glad that the Leslie using, keyboard playing world has finally caught on to this little treasure. I was looking to replace my Leslie upper driver YEARS ago and what caught my eye was: 1) it's a phenolic driver like the original, 2) it's 16 ohms like the original and 3) it's frequency range tops out at 6,000 Hz. HELLO!! This IS the upper range of the HAMMOND!!! It captures every tone and nuance just like the original ...except it handles a lot more power at about a quarter of the price of the Altec replacement. What could be more perfect?

Rated 5 out of 5 by from dayton d1075tI purchased this driver to use in my Leslie speaker. My stock driver was distorting and presumed blown. I needed a replacement quickly and knew that PE delivers fast---so I bought the Dayton driver and installed it. The Dayton d1075t blew me away! It was clean and handled the volume much better than many expensive drivers I have previously used. If you need a 16 ohm upper Leslie driver don't hesitate----buy it!

Rated 5 out of 5 by from Leslie Speaker treb driver replacement @ low cost at last !first I converted the cabinet to the mounting plate and spindle bearing available elsewhere on websites - tried this driver with skepticism. Dialing out the transformer is just a screwdriver turn and its good to go at 16 ohms. I ordered 4 more and expect to use them as replacements after being disappointed with the factory supplied "ferro-fluid" drivers which have failed. Comparable Atlas brand would be about $175. I have several Jensen orig needing re-coned but that would cost more than this driver.

Rated 5 out of 5 by from Best value for your moneyI've been using a pair of these with the 16" horns from 2005, to this date they still continue to impress me. I use them to do mobile PA, they are durable, that's why i got four more.

Dayton Audio D1075T 75W PA Speaker Horn Driver with 70V Transformer

do i use only a 75watt amplifier with an 8ohm load or can i use any amplifier with the d1075t driver

Asked by: alphonso
Any amplifier can power this horn as long as it is set to the 16 ohm bypass, it does not have to be 75 watt.

Am seeing references to a "16 ohm bypass" on the transformer. As a replacement horn driver for a modified Leslie - the original amp is not being used - can this be set to 8 ohms? .

Asked by: Chronic Iguana
Unfortunately no, this driver is only available with a 16 ohm diaphragm, there is no 8 ohm setting.
Answered by: MattP

Is it possible to connect the output from a home stereo amplifier to this driver provided the transformer is set to the 16 ohm bypass?  

Asked by: g0tw
Yes. You will need to make sure a high pass filter is enabled or in place as to not damage the driver from low frequencies.

I have a 160-watt Amplifier. The exits (70-volt and 100-volt) also (4 ohms and 8 ohms) I want two Horne drive compatible with the device

Asked by: yassin
A pair of these drivers will work fine either with the 70v or 8 ohm output, as long as the drivers are wired in parallel. If you use the 8 ohm output you will have to set the transformer to the 16 ohm bypass on the drivers.

How would this be mounted in a vintage Leslie speaker? Do you have a bracket to mount it with?

Asked by: Chandler
It uses the standard 1 3/8" threads for horn drivers.
