Pics new DIY Yuichi and large 'Altec' Bass Horn

[atilsley]

Just finished the Yuichi, with new Radian (Berylium) two-inch exits.

The bass is my own design using Altec 515 woofer. Porting to the side of the cabinet can be 'tuned.'

I'll build a passive 2nd order xover for the Yuichi, while the bass will run off MiniDSP.

Lot's of CNC'ing here but still quite a few hours of hand wood working.

I quite like the look of the lighter Birch...and I've not yet added any stain/wax.

Initial sound is very good...plenty of scale and detail.

 

[SpeakerFrank]

Nice work! Like it very much!

 

[thunk303]

Well done mate! Fantastic workmanship... Hope it sounds great!

 

[POOH]

Nice! You have lots of work in these, it shows. They should bring many years of pleasure

 

[Cal Weldon]

In awe once again.

Cheers.

Would be interested in your opinino of the Yuichi vs the conical/LeCleach? horn youhave

 

[gafhenderson]

Any measurements for these? Particularly distortion sweeps with the yuichi horn.

 

[Fuling]

Excellent work!

Are there any plans or HornResp data available for the vented bass horns?

Beautiful work! One of thesedays I'll splurge on a nice CNC machine...

I wished you were here in this part of the commonwealth, so I could hear, maybe buy a pair of those bins.

 

[djn]

Those should sound very very nice. As I understand it, a front loaded horn's driver should be inclosed in a very specific sized chamber. Great work!!! I look forward to hearing your impressions.

 

[Altec Best]

Yes very nice ! Also looking forward to your impressions especially on those Altec bass cabinets.

The bass bins remind me of the Exemplar bass bins & also that article from Sound Practices. I assume they go to about 150hz after which the bass reflex portion takes over?
Nice stuff ...

Thanks for your kind comments, guys.

See attached sim, plus mic sweep.

I'm also building small wteeter horns...and I collected one yesterday. I have new Selenium D220 drivers for the tweeters.

My main system is Azura 340hz, with JBL 2445.

Listening to many horns from Altec 511, 811, 8005, Smith, Stereolabs, plus the Yuichi....I'm reasonably confident in saying the Azura is the smoothest/nicest sounding horn I've had. I'm now tempted to get the big 160hz Azura and build a Trio replicer/beater.

If I continue down the wood turning path, I'll replicate the 340Hz Azura with a ply horn, like Tune Audio.

Because a lot of my projects use CAD/CNC, I can supply advanced flat-pack kits.

Here's a pic of my all time fave horn...Eleven Horns, Jeff Jackson.

Here's a lovely Yuichi horn and matching cab....this guy has done very well.

These are beautiful!!! I'm sure they sound very good too. What lathe do you have Atilsley???

I bought this lathe last year to turn 30" horns but have not gotten around to turning them yet.
