I have been smitten by your "homage to the Altec Model 19" for some time and was wondering if you had a page or build info/pics of that fine speaker.

Thanks

Let's see....the cabinets are at Speakermans, the 2226's are in the BatSpeaker bass boxes, the 902's and 811's went to a guy in Texas,IIRC.

Remaining pix:

All I could find.

The 4 cu ft box with 2226 and B&C DE-250 on top with woodhorn sounds better. Much better.

A lot of the success is due to the 4 cu ft box tuned to 42 Hz instead of the 8 cu ft tuned to 37 Hz of the 19s. Also using a motor run cap for the 22uF in the crossover and a Kimber in teh attenuation circuit. Biggest improvement, tho' is the B&C driver.

I don't know if I'll ever spend an entire summer veneering 12 sides with multiple leafs. The BatSpeakers look like shit and sound heavenly. There's a lesson there.

Of course, nothing I build will ever take the place of these:

Thanks for your kind words.

Hi Bill,
New to this forum so hope you don't mind me asking a question that may have been asked many times. What is the crossover point between the JBL 2226H and DE250? Is this a Pispeakers design as I don't see the DE250 option on the web site. I am quite keen on using the same drivers and after a long search I found your post in this forum.

TIA
