Hey Everyone,
I'm having a hard time making a choice between all the available options for amplification out there. I have a 4-way dipole design (kind of similar to LX521), with the following arrangement:
23-110Hz, Dipole sub:
This is using dual 15" drivers, each measuring 3.4 ohms at the lowest point in the sweep in my freq range. I'm using an XLS2500 with drivers in parallel, red LED periodically lights up on really big bass hits. measured amplifier output level to the drivers is regularly reaching 650W with my music collection.
110-550Hz, open baffle mid-bass:
requires about 200W peak, dual WO24TX-8's
550Hz-2.3kHz, Coaxial midrange:
no surprise this only requires about 10-15W max
>2.3kHz, tweeter:
less than 5 watts normally.
I'm using a DSP for the crossover and compensation equalizations.
With the amplifiers I currently use, I can hear hiss and other noise from all frequency ranges. I'd like to upgrade. I can certainly find adequate power in the Hypex lineup for the subwoofers and mid-bass ranges, but I'm not sure what is the best option for the mid/tweet coax.
I could pick up 2 stereo amplifiers from Buckeye for example, the NC502 (each channel feeding a single 15" driver @ 3.4 ohms), and the NC252 (one channel feeding parallel WO24TX-8's [2.9 ohm], the other feeding the coax with passive crossover at 2.3kHz [3.6 - 6.0 Ohms]), but in this arrangement so much headroom is available for the coax driver. It feels suboptimal, as I lose the DSP benefit for mid/tweeter crossover.... and I worry about my coaxial's death should something bad happen unexpectedly.
Also, I feel it's not normal to have 250W available for a midrange/tweeter.... seems like using a semi truck to pickup groceries.
What should I do? I look forward to any recommendations or suggestions you have to offer
