will write email to Bendor as Scott sugested and see that option also...

Thanks once again, I will get back for some more advices once I buy drivers as am like newbie even as I have build one pair of loudspeakers (but newer fineshed them).
Because you are going active.. there is another potential solution.

I'm not sure if it will be better than the Bandor driver for your application either.. but it does sound pretty special (..having both high transparency and tone):

http://www.expolinear.de/images/stor...%20130%20g.pdf

They are only showing the "T" & "S" version here:

hifisound eShop*-*Goerlich

The "T" version is midrange-only. But the "S" version is largely comparable to the "G" (..in fact without looking real hard I'd be hard-pressed to say there is a difference):



Here you can hear one of these drivers ("G" or "S") on the Ensemble Primadonna:

Ensemble Primadonna 4 - YouTube

..not bad, eh?

Because of the smaller diameter it will be a better match for a higher crossover freq. for the RAAL. You will need to take care of that "peak" between 1-2 kHz though..


Unfortunately, not exactly in-expensive.

Do you have any subs? If not, how about a three way?

yes those Goerlich a little expensive...and they are out of budget...plus, as I'm newbie, I think it will be a too much for me to get rid of that peak around 1-2K...

The simpier the better

I don't have plans for sub, not for music...have one, low qualiti yamaha for HT, maybe would build one more but only for HT...
dimensions of room are 3,5mx6m...listening position would be like 2.5-3m from loudspeakers
loudspeakers would be on 3.5m side...
So I think that there's no nead for sub

seriously? you want to recommend Driver via a bloody YouTube Video Sound sample.
hell! you are brave.

and the next Thing. a 13cm Driver for the raal 140?

Minimum would be two 13cm Driver as a d`appolito

in my expirience a big 6 1/2" Driver or a 8" Driver works super nice. the 8" Driver even a bit better Dispersion wise.

best

Dynamically a larger driver would be a better match, but dispersion? MAYBE vertical, but certainly NOT horizontal. It's a trade off and I would personally go larger and more dynamic as well, but it certainly does not "match" dispersion.

i guess 8" do fit. :-)
raal 140-15dam with w22 seas excel 0-50 horizontally.
measurement is windowed, so 500/600hz and up.

Yup.. Having heard earlier ensemble designs using this (or a very similar) driver. Also looking over the spec.s.

A 6.5" driver usually starts having more significant pressure loss off-axis around 1.7 kHz, an 8" is closer to 1.4".. There are however some exceptions to this (based on cone profile). A 5" driver is usually closer to 2 kHz.

In contrast the RAAL is pretty much "omni" horizontally, getting the crossover right is just easier with a smaller diameter driver.

An MTM also has some problems - midrange combing, and the RAAL's 7" or so of spacing wouldn't be doing that design any favors.

Still, a 5" driver with modest xmax isn't going to produce low bass at higher volumes. What that particular driver can do is produce reasonably low bass from a smaller enclosure, just not loudly.

If you have a larger driver and crossover combo with the RAAL that works really well - Please share! EDIT: Thanks!

Very nicely done!

What was the crossover?

i build some speaker with raal 140 with for example hm170MN0 (6 1/2) in a 3-way. nice, but not perfect horizontally dispersion.

with 7" focal audiom midrange,

8" peerless, accuton and paper or magnesium Excels.

chose the 8" magnesium in a 16/17 litre sealed enclosure, with a 680uF cap in front. goes down to 44/45Hz -3db

BTW, here is an example of a 8" driver very well suited to the RAAL (at least with respect to dispersion):

http://www.zaphaudio.com/temp/PHL_25...5-30-45-60.gif

The only problems is (in this case): it's a midrange.
