dudeogo Posted May 13, 2017 Report Share Posted May 13, 2017 I have decided on 2 FU Audio 750v2 18s on a CAB 1600.1 @1 ohm. They will be in a 12 net cubic feet box I designed tuned to 34 hz. Any suggestions on changes in equipment or box before I commit and order parts?

ShadeTreeMechanic Posted May 13, 2017 Report Share Posted May 13, 2017 To do it the right way from the start, honestly I would choose a different amp. While a few people have had success with it, it seems to have a bad track record for reliability. bdr electronics is a well known amp repair house that does warranty work for Sundown. They have great deals on refurbished Sundown amps that carry a full warranty. http://www.db-r.com/sell/store3/index.php?main_page=product_info&cPath=1_45_97&products_id=171 91 C350 Centurion conversion ( Four Door One Ton Bronco) 250A Alternator (Second Alternator Coming Soon) G65 AGM Up Front / Two G31 AGM in Back Pioneer 80PRS CT Sounds AT125.2 / CT Sounds 6.5 Strato Pro component Front Stage CT Sounds AT125.2 / Lanzar Pro 8" coax w/compression horn tweeter Rear Fill FSD 5000D 1/2 ohm (SoundQubed 7k Coming Soon) Two HDS315 Four Qubes Each 34hz (Two HDC3.118 and New Box Coming Soon) Link to comment Share on other sites More sharing options...
dudeogo Posted May 14, 2017 Author Report Share Posted May 14, 2017 For that price, I'll buy that amp!

They're all on paper sketches, I'm not very good with Google SketchUp. It is 12 cubes net with a 26 inch long slot port with a port area of 192 square inches. So 16 square inches per cube.

Triticum Agricolam Posted May 14, 2017 Report Share Posted May 14, 2017 Sounds good. Those subs are going to roll off on the low end a bit higher that other subs would, I'd be tempted to tune a little lower, like 28 - 30 Hz. You would lose a little output in the 40-50 Hz range, but you would gain some between 30-40 and would have smoother frequency response. Just a suggestion.

1gggman1 Posted May 16, 2017 Report Share Posted May 16, 2017 Those CAb amps will certainly do the job... Yes, I've had some issues " possibly caused by me"... but warrantied with no issues and I'm running them at 2 ohm each into EVL 12's in a small box tuned to 28 hz or so... it doesn't make water ripple in China like some systems do, but I'm happy for now... I'm sure I'll tear it all apart again eventually... LOL ! I'd recommend this amp to anyone who is tryin' to save a buck!... this was when I ran 3 12's @ 2.66 strapped... still have same amp rack... This is the current setup... tuned to 28 or so... each amp loaded at 2 ohm...sounds good to me! Link to comment Share on other sites More sharing options...
DLHgn Posted May 16, 2017 Report Share Posted May 16, 2017 That bracing is pretty low and won't do what you're wanting it to do. Link to comment Share on other sites More sharing options...
