Aluminum midrange recommendation

[LING GOWA]

I'm trying to find a high quality aluminum 4'' mid for under $100.00 USD.
About 90 db (1w/1m)
Flat from 500 Hz to 3500 Hz
8 ohm

[Mazeroth]

Have you selected the other drivers to compliment the mid?

Can it be Ti? TB W4 1337 of course. :B I'm not aware of any aluminum driver that can outperform it as a 4" mid.

2 Seas L18RNXP + LCY130

RS52, though 500Hz is the bottom end of what it can do. And it's not 4".

Forgot the RS125. Very good driver- though I wouldn't take it much higher than 2.5k.

Vifa PL11. Not metal but is Twiggy-flat with a high efficiency for your desired range.

[thadman]

you're asking a lot of bandwidth from a rigid cone, what drivers will it be crossing to?

[cotdt]

the Jordan JX92 can do it... it has a properly dampened aluminum cone...

[Hdale85]

So can the W4-1337SA.

Very nice example, although its very expensive and it doesn't quite have the sensitivity he may be looking for.

You can get the Jordans for $120 each in the group buy, but good point about the price, I guess it still goes over $100. The LCY's are lower sensitivity than advertised, and the L18 woofers are not that sensitive either (if he's going to maintain his 8ohms) so the sensitivity is OK. If the OP really thinks he's going to get to the 90 dB mark there is either something wrong with his measurements or his crossover plan.

One more suggestion: RS52 dome mid.

OP: Why not just build Zaph's ZDT3.5? You can adjust the crossover to use the LCY's.

If he can extend his budget a little bit, the Jordans would also be my recommendation since they don't require a low crossover point. The L18s is more of a midbass than midrange with reference to the Jordan.

These look interesting- though not 90db.

Yes, Ive thought of the MarkAudio Alpairs but haven't seen anyone use them or seen any independen testing. the only info I can find is what's on their site.

I actually have a pair of the P11MH09-08 which I'll be using in another design.
Have you used this mid or know someone who has?

I have the PL11WH in my computer speakers with a Vifa D26NC05. I got the PL11 on sale from Madisound for $35/. They're typical Vifa paper. Not quite as "airy" as some metal cones, but very full midrange. They seem to have the speed of a good dome but with much better bottom end. I'm using mine up to 5500Hz without issue (figured for nearfield, the higher xo point would keep things cleaner.)

The Alpair Drivers are a new product by Markaudio (us) and we are in the process of getting independent reviews and specifications of our drivers. We do have some dealers now (especially in the USA) and so more independent information should be available soon.

All of the non-formal feedback we have received is that they perform to the specs published on our site.

[minkuni]

Are the mechanical drawings of the Alpair 6 correct? If they are, why the odd placement of the screw holes?

[Scooter]

My vote would go to the Visaton AL130M. It's 5", but fullfills all other criteria very well. It's close to 80€ at the moment, with the falling € it could get within the budget soon :W

C'mon Jed, live on the dangerous side! :B Cross it high! Cross it high!

What about the MarkAudio CHR70?

I think the Visaton AL130M is a good candidate.

From the Visation graph, it doesn't look very flat. More of a constant rise. $136.85 EACH CAD + TAX + SHIPPING.

I have 4 L18's that I would love to put to good use. I built Zaph's 'All Aluminum' and it is very nice at low volume. It seems to me that this driver is better suited for low end duty. However, a while ago I had the pleasure of listening to a design with the L18 & HDS tweeter crossed at 1.7 that sounded sweet and played LOUD. I couldn't squeze any info out of the designer though. Too bad since I have a couple of HDS tweets looking for a home.
I still like the idea of the L18's in a multi way better.

Anyway, thoughts and suggestions are surely welcome.

It also has the double peak breakup resonance typical of the older generation aluminium cones. Newer designs like Zaph's new driver and the Fountek 5" will give you a wider usable bandwidth. But I would not use either of these beyond 2.5kHz.

Vifa PL11. Not metal but is Twiggy-flat with a high efficiency for your desired range.

I wonder why you don't see that driver used more? I wonder if the (non-MTM) Sonus Faber Toy / Toy Tower use a straight up PL11, or some variation. I think the MTM uses a 16 ohm version.
