the italians think they drive fast enough not to worry about blindspots - on many italian cars in the 70s the door mirrors were optional extras (Alfa)

Love Gandini's work tho, especially the Miura - his trademark on most of his cars is that odd shaped rear wheel arch - seen here http://www.hkcarworld.com/sites/defa...lo_gandini.jpg

back to speakers, I hope that 3db is enough, I'm thinking most people find a full 6dB BSC too much?
I want to have a certain balance to the sound and not overpower the treble on the alpairs- I'll pad the 10P's at the back anyway, so the output will be reduced slightly, plus the 10% slant on the baffle will tame them a bit

The 10P's have a 50 ohm spike at Fs, which starts to rise south of 200hz.
With a first order at 300-350hz, I hope I can get away with it

That makes a big difference. Typically you want 3-6 dB and XO at or just below the baffle step.

I ended up shelling out on four Satori's to go with the Alpairs; I hope a 1st order x/o is possible.

I bagged the last 4 at falcon acoustics… really looking forward to this build, I think the satori's and alpairs will be a good combo

Should make for a rock solid combo. I'll be watching closely!

Default Update requested!

Hello,

How did the FAST style arrangement end up working with the Alpair drivers?

Cheers,
Tal

I finished up with an Alpair 10.3 M U-frame/shallow open backed box if u like, over an SBA 8 alloy woofer in approx 40 L box. U-frame/Box from epoxy, MDF, porcelain tile. Etc. Port tuned buy ear. Passive XO approx 400Hz, padding on the 10.3M. They weigh 70kgs ea. took me 3 years of spare time in the man cave. I finished 3 months ago. They sound gr8 but are a bit too big for my space: need to be (sound best) further away from the walls than is practical. But I drag them into centre of room for a listening session whenever I get the chance. They have sum large impedance correction on them and you have to put the boot into them a bit to get them singing. I used Troels Gravesen's 'Acapella' as a starting point but just omitted the tweeter. I've invested alot of time and money into them. I'ved finished with speakers for the time being, I still have a small SE valve amp kit to build. Thanks for asking
