Hello i am here to ask your advice on what amplifier build to drive my self-built speakers with Seas Exotic F8 driver inside a Back-Loaded Horn cabinet , the driver have a minimum impedance of 6 - 7 ohm (this chart of the impedance image [url=https://postimg.org/image/empbr8zwh/][IMGDEAD]https://s24.postimg.org/bsm6dsxqd/f8_imped.jpg[/IMGDEAD][/url])
I had thought at first watts f4 or f5 but I accept any suggestions. Thanks

An F6 is fantastic, and is a simple build if you buy the semiconducters from the shop.
An F5 or F5 turbo can be scaled up if you want more power.
Buy at least a 400va transformer then you have options open to build other amps when you get the bug.
Also start off with a good big case with big heatsinks.

Thanks I have read this pdf but I am not so expert to understand every part so I try to send to the forum the graph of impedance (first post) of my loudspeaker to get some advices. I think that also first watt F1 is good amplifier but 10 W are sufficient for a 95db efficiency ?
The Seas Exotic 8 prefers a decent damping factor and a little power, so
something like F5, F6, F7, J2 are all good candidates. If you are building
your own, try the F5 or F6.
Personally I like them in a larger volume sealed enclosure.

Thanks for your advice, it is for me an honour, I think I will start with F5 or F6. I am interested also to try the F4 with a tube preamlifier.
