One of the best cone midrange drivers I've hear - kid you not - is the Eminence Beta 8.
For Hi-Fi it's superb. Doesn't look like much, but it's super clean. Usable up to 6K with just a small inductor to flatten it.

Thanks Pano!

Recommendations so far:

10inch Celestion TF1020
10inch Fane 10-300 http://www.faneinternational.com/dow...0300_Specs.pdf
8inch Eminence Beta 8 http://www.eminence.com/pdf/Beta_8A.pdf

Any more suggestions?

Is a 10inch really too big? Will the Beta 8 look daft paired with a 'big daddy' 18? And more to the point will it keep up output wise? Also will it survive coming in around 200hz?

What should I look for T/S & design wise for a driver with killer mids?

Pano,
You use the ALtec 416, correct. Was this intentional, as it allowed dropping the midrange and mating directly to horns?

And the 4344 does look nice!!
It's a nice sounding system. It's 15" based set-up using a 2235. The larger 4345 uses an 18" 2245 with identicle upper componenets and crossover. A 4434 is not all that big compared to the 4345 which is about 10 cubic ft. Here a comparison shot to a JBL Array clone for size comparisons.

The Seas Prestige A26RE4 10" woofer makes a great midrange driver. Easy to cross, too.

Also in the same price range see the Seas Prestige FA22RCZ 8" fullrange. Superb driver. Either will mate well with a 15" or 18" driver.

The 416 was typical in the A7/A5 speakers. And that's what I have. The 515 can also be used to good effect and is more efficient than the 416 with a reputation for better top end. Less bass, tho. Either can be crossed easily at 700Hz or higher. There are other choices, but this works, so I use it.

I have a pair of NIB AE TD18H+ woofers I'd sure like to incorporate into somebody else's big build.

Hi all

I forgot about these. They might just be what you're looking for and will probably work well with 8w as they're a modern design that is designed to work with low power :

inConcert Miles

They might just what you're looking for, and they're a completed design. High efficiency (over 100dB/w), and not too big. And the drivers should be easily available in the EU. They also have a smaller brother:

inConcert Duke

Enjoy,
Deon
