We enter a complicated region as the lower driver we go the drivers could be used for different purposes and it is very hard to generalize. A 10-incher might be MF driver and LF driver. In my past I experimented with few MF 10-inchers, including some...

Well, the game with a “better” 10" bass driver is over. After years of mind looking for the 10” light-coned, papered 20Hz drivers with higher sensitivity and after a month of quite active searching for such a driver I concluded that such a driver jut...

Haralanov,
Here some raw cements of my on it, without any particular order of importance….

[quote user="Chirag"]Outside of the already constructed bass towers, is there a reason you are looking exclusively for 10" drivers? I have heard a pair of stacked 15" Lambda's on each side supplementing/providing bass to lower midbass under som...

Hi Greg,linkSearch the site and you'll find that Ulf has created a upper bass horn using the aforementioned TAD 1201's.I also own a pair still in boxes waiting for the weather to warm up enough for me to start some enclosures and horns for.My origina...

Further looking at where I would like to take the new 6-chennal version of the Super Milq I am contemplating a new revision of my bass channel output transformer. Currently I have Jack Elliano’s made 450mA, large, single section LF transformer that b...

Hello again,I've found four Scan-Speak 25w/8565-01 and possibly two -00 for sale at a good price.I'm triamping as of today and hope it's a good idea to start with the four and perhaps add more when I can afford it.- Do you think the 01 version would ...

Hi Romy,So it is time to think about the bass output transformer in my DSET. My bass channel will be 8 x 25W/8565-00 each side set in a sealed box and will cover the frequency range below say 100Hz. These drivers can be wired anywhere between 1R an...

I too want a monitor speaker to play with, especially for amplifier experimentation.I put another 4" Fostex in a sealed "box" (globe actually) and crossed it over at 150hz to one SS 25w/8565 on the side. Wishful thinking? -Yes.About 88-90dB sensitive...

@N-set I was replying to pauls comment about giving up on blending passive radiators and trying to say I was surprised how effortless the 8565 integrates upwards into the tannoy but integrating down into another channel there is no hope. I think the ...

Forgive my complete ignorance in the speaker design, but if Edgar is right and the passive radiator has to be the last one, why not adding a sub with a passive? A sub with the same 8565 as a passive?
I hear you re the injection,...

Could keep it simple and fire straight down onto the floor. I think

Hi, Ronnie.
I do not know what happen with emails, you probably should not use the world Viagra in there… :-)

Hy Paul, I agree with your comment about the tone of the passive radiator if it runs to the mid range. This is the point of the SS8565. the combo of the crazy stiff cone and the special surround works phenomenally well to stay linear. It is even bett...

[quote user="Romy the Cat"]Make the full-range and then you will see where you are.
Still, I feel that for MF channels it is beneficial for do with a good DHT output
stage instead of 6C33C and perhaps it is a good idea to use DHT driver as well.

Well, I kind of begin to think what kind LF solution I might
have in the new room. The ULF might be fun to load on the ceiling in the way
