I've used earlier versions of the 170mm Aerogel with great satisfaction- wonderfully clear mid-range.
I plan to use one of those speakers as midbass in a 2 way system, using 6dB/octave XO, and a transmission line
would they be any good?
would they be any good?
I'm not a big fan of 6dB filters in general, but the Aerogels I've used do have nice HF rolloff characteristics.

I've used the HM170G8 in two pair of speakers, both TLs. One pair is a two way, the other is a 2.5 way. Both used 1st order crossovers. It's a very good driver. In general, the Audax treated paper drivers have a bit more "body" to their sound when compared to the carbon fiber units which I've also used. Both the papaer and carbon fiber units are clear, quick dynamic and very well behaved.

thanks a lot! I was starting to forgive this topic 😉
Can you tell me more about the speakers you build with the G8s?
and what other speakers you used, to see with what competitors they were very good drivers 🙂
I'm using the G8 in a simple straight forward br-enclosure of 19 l. -3 db point is around 50 Hz. So far it isn't disappointing but I've to fine tune the x-over (6 db)
It's a good driver for the money, midrange is clear and detailed. And dynamic too. But I've to research a little more to make the most of it 🙂

I have the HP130Z2 using a 6dB. x-over, sound awesome; now I find that I have to fix the reflections in my room for, the harsheness I hear is caused by the room...outdoors they sounded great! In a nicely treated room, even better!
Bricolo,
The first TL I built using the HM170G8 was a two way. The Audax was mated with a Dayton Pt2 planar tweeter. The second pair I built is a 2.5 way with two of the HM170G8s and the Seas 27TFFC on each side. Both speakers used 1st order crossovers. The 27TFFC is a very nice tweeter. The Dayton planar is actually a bit clearer that the 27TFFC, but I think in the long run, I'd prefer the 27TFFC. I've not built a lot of speakers so I can't provide you much in the way of first hand experience comparisons. In terms of woofer, I've used Audax exclusively simply because I really like them. The HM210CO is another very nice woofer. It too can easily be used in a two way with just a coil on it. I have a TL with it too. It's mated with the TWO25A1.
Did I answer your question?

Bricolo,
Sorry...I just reread your post. While I've used Audax woofers exclusively in my DIY speakers, I've owned Apogee Stages and B&W 801s. When I built my first TL with the HM210CO, I preferred the Audax TLs over the 801s by a not small margin. They are just more lively to my ear. The HM170CO is similar to the HM210CO. Like I said in my first post, the Audax paper drivers have a tad more "body" than the carbon fiber units. I think you'd be hard pressed to find a better driver especially if you're looking to stay with 1st order crossovers.

thanks, yes you answeared my question 🙂
It's nice that you gave your advice here, since I was hesitating with some audaw midbass, including the 210CO 170C0 (and also the 170Z12)
So you prefered the G8 over the carbon ones, did I understand correctly? They gave a more detailed sound?
was the G8 better in everything, or did the other ones a better job in some cases?
what about the tweeter, how did the audax compare to the others?
thanks a lot
Alex
Bricolo,
I don't necessarily prefer the G8 to the carbon fiber units. As I mentioned, they have more "body" to their sound than the carbon fiber units so it comes down to what you like. I can listen to the G8s and really like them, but when I switch back to the carbon fiber units, I really like them too. I could easily live with either. If I had to pick one, I suppose I'd pick the carbon fiber units simply because my preference for sound runs on the lean side of things, but I know there are lots of people who like a tad more "weight" to the sound and that's what I mean when I say the paper units have a bit more "body."
As far as the Audax tweeter...they work very well with the Audax woofers. I've not regretted using the Audax tweeter with those HM210COs, but the model I used is no longer available. I've actually forgotten if the one I used was the A1 or A0, but I am sure that it's no longer listed. I have heard from a reliable pair of ears though that the unit that is available is also a very good tweeter.
I decided to try the 27TFFC simply because there was so much good written about it. It is a very good tweeter and you'd probably be happy with it too. It's probably has a bit more clarity than the Audax tweeter, but others might call it drier than the Audax tweeter. Again...it comes down to your preference.

I think I misunderstood what you called "body"
For me it did mean "more detail", but it seems that for you, it means "more coloured"

Bricolo,
I guess there are some who would say that what I'm describing is more "colored." I'm not so serious about this hobby that I understand all the technical reasons for the difference in sound nor do I much care. I know what I like and also know that every person doing what we do has different tastes. "Colored" seems too critical a term for what I'm trying to say because there's no question that the G8s are every bit as clear and detailed as the COs. What I'm tryin to say when I say more "body" is like the difference between listening to the same piece of music in some small nighclub versus a nicely designed concert hall. You'd probably "feel" the music more in the nightclub versus the concert hall which would tend to give you more "air." I'm not trying to say that the differences that I hear would be as drastic as that, but that's kind of the character of what I mean by "body."
I could live happily with either the G8 or the CO units. I've swtiched between the two pair of speakers and have never felt that I was missing something when listening to either. It just depends on the mood I'm in.
Hope this all helps.

A20 & A26
Hello,
I have early experience with the new Audax TW025A20 neodymium titanium and TW025A26 neodymium textile tweeters.
I think they rank a class above many references.
As for G8 and C0, the body factor is mainly due to the fact that the paper unit has more output in the midbass. HM130Z10 is their best midrange. Audax has the best paper in the industry. But paper sounds duller than carbon. Overal it is more balanced though. I would use a couple of G8's in TL, a couple of Z10's one above the other-open baffle or irregular box, not D'Appolito- and an A20. 6,6,12dB cross.
That way I would start. A series 6dB cross would be my alternative path.
Regards
Salas

Sorry, Bric, I've been on the road for several weeks (including a terrific weekend in your lovely country) so my checking in has been sporadic. Anyway, no, the 170Z0 didn't seem to have any severe breakup below the 3K crossover that I used. I should point out that in these designs, I tend to use rather steep slopes (4th order). I've used the HM110G0 for a center channel speaker I built for a friend and it's quite smooth, if not as detailed as the Aerogels.
Don't tell me that you went to Alsace; and that you haven't sent me a mailSY said:
BTW, what was so terrific in France? Have you seen thousands of peolpe in the streets? Quite normal since a couple of weeks 😀
So HDA is more detailled as paper
But have you ever tryed it with 6dB/oct XO? That's normal that you haven't any breakup with 4th order XO 😉
