Moving on my other set up I like are the full range drivers, these are Lowther PM4a drivers. Running in full range mode, with the right cabinet, they can go to 30hz but usually you'll get them down to about 50hz. They are an 8 inch paper cone and a 30 ln magnet. The downside to these are the cost, they run about $3k a pair. In our little auto comparison think of them as the Bentley of this group, a nice stodgy British technology that has been around and hasn't changed since the 50's
I am crossing these over at 250Hz, everything above 250 goes through the horn, everything below goes through the ElectroVoice Sentry IV bass bins. These bass bins are another bass reflex design using a pair of 12 inch EV drivers. One of the questions we had was to see how it compared to a single 15 inch driver on the Altec 828 bass bins.
One other big consideration that I haven't mentioned is the curve of the bell of the horn. Klipsch uses a Tractrix design, Altec uses an exponential design and these Azura horns use a Le Cleche design. You could have pages of discussion just on what horn technology is the best but for me, I really like the Le Cleche. It doesn't look like it should but it really focuses the imaging spot on. On well recorded albums the vocals are dead center in the middle.
I finally removed the extra amp and other pair of speakers and I like the less cluttered look of this wall now. If I could only find a way to hide the Lascalas now.
Here's a little fun from last night, as you can see I'm really not playing this loud but you can feel the music vibrating in the arms of the chair without using a sub to make the floor thump. I was really surprised how well this album is recorded. Usually rock stuff doesn't sound good on these.
Here's another direction you can go, I have some stuff listed on CL and one of the local audio dudes offered this for sale to me. It's the Azura horn with the TangBand W8-1772 drivers and Fostex T90A tweeters. He's using a Marchand XM-9 for the crossover and JBL 2242H drivers in JBL ported bass bins
The Azura horns go for $600 a pair
The TangBands go for $450 a pair
The Fostex go for $400 a pair
the Marchand $400 to $500 used
JBL bass bins a couple hundred bucks
JBL 18inch drivers about $1200 a pair
If you are in the DC area, this guy is selling the horns, Tangband and Fostex drivers for $1,000 which is a pretty good deal. You would just need to add a crossover and bass bins and you would have a killer horn set up for any of the EL 84, KT88 or KT120 based tube amps from Carver. If I wasn't down sizing I'd be all over these.
