Hullo and Altec 604 16 X Cabinet help please :-)

Hi all

Thought I'd stop in and say hi since I see there are good chats happening here about gear I love :-)

I'm based in New Zealand. Currently running Klipsch Jubilees, my GF wont let me move in to her place with them (!).. they are huge -to be fair to her. I also have a set of Altec 19s and some other gear laying about, but I have recently come across a pair of 604 16X drivers that I am experimenting with.

Because the Jubilees are fully active, I have a great Xilica DSP / XO system and nice amplification to work with. The 604's also came with Markwart XO's but I enjoy the flexibility of the Xilica and will use it with the 604's exclusively I think.

I am currently playing around with the 604's in old Altec 19 cabinets - simply because I had them laying about. Getting some excellent results with a Pass XA 25 driving the woofer and 2x Bryston 7bSST's doing the horns (400wpc tweeter amps... what could possibly go wrong????). Whilst they aren't quite the speakers the Jubilees are - I think they will work well in their new setting.

But I need some advice about cabinets for them. There is almost no literature around the 16x version of the 604 - but Altec's own documents suggest they will work fine in a 620a enclosure. Should I just build these and be happy, or is there a better, pre-existing design that I can build readily that you can recommend? Love to stay around 9-13 cu ft for room aesthetics, happy to look at MLTL etc.

Again, the Xilica gives me full DSP, time delay etc so I have plenty of tunability right there. But I'd love to start with a cabinet that is as close to optimal and/or a proven winner for the 16x.

Appreciate any stimuli here - thanks!

you will get a lot of advice here re 604 cabinets. the 620a cabs would be a lot smaller than your jubilees so that could be the ticket. i think some have tried stonehenge cabinets, which are tall and thin and might, therefore, have even more girlfriend approval.

Plus one on the 620 cab, I modeled my cabinet build on them. Although larger cabinets can give a little bit more on the low end, you are better off with subs or a 6v6 push pull amp to get the deeper bass.

Agree with the comments above. Since the 604's need the large cabinet that are not going to be approved, you might want to just jump to the idea of using a subwoofer or two with the 604's in smaller cabinets. Go with the strength of the 604 with he mid range and let the woofer do the heavy work which are easily hidden (maybe) in a room in terms of scale.

Since you have the nice DSP set-up, you could start with the more modest size cabinets with the 604's and see if you can equalize in enough low end first.

If you feel the need to stick with Altec you could also sell the 604's, find a pair of 414's and add a horn to those in an overall smaller speaker.

Otherwise it's simple, no, she wins. :cool:
 
I also am trying to mod some huge cabinets for my 604G's in Big red cabinets.
Markwart X-overs.
they are just about the same size as the 612 cabs only they have a huge full width
bottom port/Tunnel.
So hopefully the ruffly 11 cu semi Transmission line cabs will kick up the Bass response a bit
I will post pics when completed by my woodworking buddy.

I've got some 604E's in (temporary) ported 26x26x14" boxes in my basement, augmented by a HSU sub, and they do quite well. 9 cubic foot cabinets are being built for me by a friend, however. :)
 
I have my buddy taking pics of the cabinets, as he goes, that I will post when done.
Hopefully you can post yours as well:BananaGuit

Mine are $20/ea. carpet-covered roadie monitor boxes I screwed to some cheap IKEA metal side-tables to put the horns at ear-level. I'll see if I have any photos. :)
