Hi, does anyone make a line array with the Seas 1597 driver, or something comparable? Thanks.

Seems like a bad idea. Ideally, you should use 4" or less drivers if you want a full range array.

A large full range driver does not yield an acceptable line array speaker.
Read my NFLAWP for why:

http://www.audioroundtable.com/misc/nflawp.pdf

(near field line array white paper) for background.

If you wish a line array made from full range drivers I suggest my Constant Beamwidth Transducer (Modified CBT24) project at:

https://www.diyaudio.com/community/threads/my-new-line-array-its-a-modified-cbt24.313352/

which uses a SB Acoustics SB65WBAC25-4 which is a 2.5 inches diameter driver. This project uses two 12 inches stereo subwoofers to cover the low end below 125 Hz.

 

And....that's why. What HE said. nt, posted on June 17, 2022 at 21:08:20

this link to parts-express.com has a couple line array offerings, this driver is 2&1/2 inches

They used to have some as kits that were concaved and huge, but I think the shipping costs put an end to that, but they were interesting.
Just put 'line array' in the search box

An 8" driver is good to only about 2k for consistent directivity. There are good reasons why you don't find full range line arrays using such a large driver. Successful designs all use much smaller ones.

Here's Roger Russell's IDM-25 using 3.5" drivers:



Scaena took a similar approach using 4" drivers up to 5k where ribbons take over:



The IDS required equalization for the bottom. Scaena used "depth charge" subwoofers.

It's not optimal, but there's no rule that says you can't use some FA22 drivers for a tower speaker.
Maybe you have access to some and need a neat project?
Go for it.

Dave.

Strong memories of Scaena. They were an effort to make a better version of the Pipe Dreams line source. But the designers(who didn't do the original design on their own never understood the original woofer design and 'corrected' it which wasn't needed. I once heard the original woofer design at Harry Pearson's with the original designer playing a cut fro the Lost World CD wit a real earthquake in the back ground playing at 16 Hz according to Harry and Harry's eyes looked like he was waiting for flying woofers there was so much clean low frequency energy.

Only time I've seen Odin with Speakon connectors!
