Subs for horn systems

Myraj, The Duo's. Thanks

Hi,

I already used a Duo, and Trio after that. I understand why do you want to improve LF. At that time, I had used a REL Studio III to make up the low freq. I think REL sub can help you to change the sound. REL is powerful and the price is not much expensive. And about the result of REL-Duo/Trio weding, I sold all Avantgardes and build my own horn speakers by using two pairs of TAD 4100 and 2100, and the REL.

Mike aka "Magnetaraus" on Agon and "Magnetar" at AA has built some very large and highly efficient folded horn subs. These are based on JBL drivers and should play very loud and go quite deep. Mike's a great guy and always willing to discuss audio and his projects with anyone interested. Do a search for him over at AA and you can probably find a link to his personal website, which has pictures of many of his various horn based projects. Sean

Bachnguyen,
Why the switch from the Trios? I'm thinking about mating Trios to my pair or REL Studio IIIs.
Thanks,

Before you abandon your SUB225s, make sure that you've set the polarity correctly (highest output at xover point, swap the wires and measure SPL each way) and experiment with the level and crossover settings. MAJOR improvements may be made by patient and careful adjustment, and by having dedicated 20 amp lines and quality outlets & power cords (Shunyatas are worth a try). Be sure to use the speaker level inputs (line level inputs are primarily there for home theater use) to better blend with the horns...what amp(s) are you using?
