What are your favorite 5" to 7" Woofers right now?

Hi Everyone,

I'd like to hear what others like. Often in this thread or that I find myself discussing, perhaps too authoritatively, the merits of better 6.5" woofers in a ported cabinet. Of course, there's no substitute for size, but I also think these woofers are under-appreciated as credible alternatives for musical loudspeakers in homes and especially apartments.

So, we know some of you can only think of folded horns, and 20' tall line arrays of 18" woofers, but for those of you who feel a 2-2 1/2 way with these smaller woofers is a great and musical choice, I'd love to read about what you like.

I know there are some lurking fans of the SB/Satori lines. I'm personally waiting on some Peerless 5" I got on sale to finish my home theater gig, and I'll post about them when I'm done.

What else are you iconoclasts happy to recommend?

Best,


Erik

To help move the thread along, I'll share with you all the spec vs. measured for the Revelator 7", 4 Ohm 18W/4531-G00. calculated using added mass of 16.7 grams

Fs 33, 48.5 Hz
Qts 0.35, 0.61
Qes 0.38, 0.68
Le 0.3, 0.168 mH (10k)
Vas 1.48, 1.09 (ft3)
Vas 41.9, 30.9 (liters)
Re 3.4, 3.51
Min Z 4.3, 3.8
 
I'm currently using a SEAS L18 in a 24ltr ported enclosure. Bass is good down to 40hz though limited in 'impact'. I have a large sub so that isn't a problem.

It's impressed me so much I'm turning it into a three way with my favourite mid/treble combination of Morel EM1308 and SEAS 22TAF/G.

Here's the two way. The port is in the bottom of the cabinet. The speaker fits nicely into a small room.

It depends on how high you need them to go?........some have a more pronounced breakup and odd order HD distortion peaks that require quite a bit of taming in the crossover. If there's a midrange involved in between, it's really hard to beat the Dayton RS180 series for low distortion motor and extension.
 
Given the choice...hmm...

I don't have a tremendous amount of experience with 6.5" midbass drivers, well hands on at least. The last one I used was the 850467 from Peerless over a decade ago, just never had any use for one.

All that said it would depend on the system I was trying to build. Although having said that I pretty much know which direction I'd go anyway (if at least for myself), a waveguide loaded tweeter + 6.5".

In that case I'd want a nice directivity match and a crossover at 2-2.5kHz. This rules out metal cones and given the choices on offer - 18Sound 6ND430, Scan revelator, Satori 6", RS180P, Some peerless HDS driver...

I suppose that would depend entirely on the price point I was trying to hit and then if the speakers were meant to stand alone. The revelator has the edge in terms of bass performance, so that would make the most sense if sheer extension was required but requires a large cabinet. The 18Sound has the advantage of higher sensitivity, but poorer bass extension, so if a sub was to be used this would make sense. While the satori is kind of between the two in terms of its bass capability and sensitivity but works well in smaller cabinets. So if size is a concern, I'd go with that.

The other two are far less expensive and as a result fall into a different category. If budget was really strained though I'd go with the Dayton and then probably with one of the Peerless drivers if I could spend a bit more. There are so many variants of the HDS drivers, different specs and different impedances, that you could most likely find one to match you requirements more closely.

That's really nice looking! :) I particularly like the footer.
