Sonido 200 SFR BLH

[yoaudio]

Dave & I are working on a few designs for the Sonido units; we haven't got them drafted up yet though. Hopefully will be getting them refined & added to the site over the autumn.

Would that include the Sonido SWR 096/A?

 

[Scottmoose]

That's the first one I worked up as it happens.

I will not be that fast in building it The more options, the better!

I'm waiting for the Frugal XL "Joan" variation for A12P and seriously considering purchasing the SFR-200A to play around with as a drop-in replacement to the MarkAudio A12P/Joan horn. Sonido SFR-200A outer ø is 200mm and the inner ø 170mm compared to A12P 207mm ø outer and 168mm ø inner.

I said email not PM, and that was for MP9) althou Scott has added some Sonindo that should be suitable for Jane FH.

Sonido SFR-175A, SFR-175, SFR-200, SFR-200a should work well, SWR-200, SWR-200a should be acceptable.

mp9: I cannot say a bad word about mine. Very flat on axis. I may add the 6x9 and the 10" field coil to my collection once the 200As have found their box

In the interests of clarity, I have never said that drive unit is a 'drop-in replacement' for the Alpair 12P per se. What has been said however is that it can be used with reasonable results in the aforementioned enclosure. That is not meant to be a synonym for 'drop-in replacement'; it will have a similar, but not identical, alignment.

 

[GM]

Is series resistance sufficient to tonally balance it out?

[Scottmoose]

Tonal balance in a broad sense is OK, it just a little over-damped < 100Hz relative to the 12P given the similar Q, Fs, but higher Vas. Not badly so, it'll just benefit a bit more from boundary loading.

 

[GM]

Thanks! Guessing then it would be more to my 'taste'.

I used the term "drop-in replacement" in that it was said to work in "Joan" horn and because the driver cutout would be very close to that of the A12p. Simple retrofit without the need for switching between multiple supra-baffle's cut to each specific driver.
For me that in itself makes the Joan horn more desirable to build for my MarkAudio A12p than a Pencil/12p. Down the road some after enjoying the A12p/Joan horn, I'd then have a painless way to play around with the Sonodo SWR-200a without investing the time and resources on a specific box build. If I were to find the Sonodo 200a superior sounding to 12p I'd then have the option of doing a specific build or sticking with Joan. On paper, I like the higher sensitivity of the 200a for use with my single-digit SET amps.

Tonal balance in a broad sense is OK, it just a little over-damped < 100Hz relative to the 12P given the similar Q, Fs, but higher Vas. Not badly so, it'll just benefit a bit more from boundary loading.

...so either corner placement to utilize the corer walls as a last fold of the horn, or Ron Clark'esque triangle deflectors against a rear wall and directly behind the rear mouth of the Joan horn?

Just wondering if you still had plans to add these?
Thinking about ordering a pair of the Sonido SWR 096/A.

 

[Scottmoose]

Sort of. About 4 on the drawing board -what kind of enclosure were you looking for? We might be able to expidite it.

 

[yoaudio]

I was hoping for a rear-loaded corner horn, maybe something base[FONT=Verdana, Helvetica, Arial] on [/FONT]the Frugel-Horn XL.

 

[bobberner]

I have drawn up a pair of FH Joans and plan on cutting them out in the near future if anyone is interested. They will be all 18mm baltic birch ply and be well in excess of 70 lbs shipping weight. I'll add them to my website as soon as I can get a shipping weight for them.

 

[Scottmoose]

I've not actually received a single piece of feedback on this design as yet, so you may want to hang fire Bob until some comments come in.

 

[bobberner]

I have someone who is on the fence about them. I would like to help get a set out there for testing. I just have no place to put them or even listen to them at this point. Not to mention no drivers to install.

I envision the ML tapped pipe by GM made in stacked laminations. The prototype would be styrofoam, final version plywood and thick acrylic sides It seems that the ML TL would work better than a BLH - I could not come up with reasonably sized BLH in Hornresp.
