Hello from Geoff H

Hi all, yet another newcomer. My background is in electonics, however these days is limited to PCs (for income) and sound reproduction for fun.

Built my first crystal set in 1964, and owned a soldering iron ever since. Also interested in EFI, motor racing and photography.

My main sound system consists of a pair of Wharfedale 10" RSDD (modified) with an Altec Lansing sub, and (currently) a pair of 3" wide range Diamond MM speakers in a Hafner rear chanel setup.

Also in the collection are a pair of Altec Lansing Atlantics, (used as a yard stick) Altec Lansing 411-8As (that need foam surrounds and cabinets) and another pair of RSDD 10s (unmodified).

Yep, I like high efficiency, wide range and fast transient response.

I am currently experimenting with poly pipe and 3 and 4 inch drivers in transmission lines. Fascinating stuff. Over the years I have read and heard lots about TLs. Some of which is not true. I still cant believe the bass I was getting out of a 3" driver sitting on top of 28" of polypipe! Nothing floor shaking, but clean down to about 50Hz. The Fr is about 130Hz.

More about that later.

Hi Geoff and welcome to the forums. I split you off into your own thread so there's no confusion.

I also have a few old Altec things laying around. Love that sound.

Thanks Cal.

What do you mean you have a few Altec things laying arround? They should be in use. Even my 1980 vintage Atlantics get to radiate almost daily. Not as sweet as my Wharfedale top end, but not as big either.

I should finnish those cabinets one day, but it means pulling them down.

Cheers,
Geoff.

Hi Geoff,

I use A4 and A7 cabinets and 511 horns for my outdoor set up. No Altec drivers. Maybe one day.

Cheers

Cal, have you noticed the A7 has gone back into production - due to demand. About 5000US$ each. Not bad for a 40 + y/o design.

See, they do make things like they used to. Just depends what yo want.

Cheers

Geoff,

Yes it nice to see a classic reintroduced. Some still claim it's the nicest sounding bass box they know. Just goes to show that the meter sand graphs don't tell the whole story.
