Visaton FRS5-8 2" Full-Range Speaker 8 Ohm
Wiring in Parallel
I am considering purchasing two of these speakers with the intention of wiring them in parallel to the Tang Band W3-881SI 3" Speakers. I am building a computer speaker type project with two separate enclosures. In each enclosure, I would have one of the Visaton FRS5-8 speakers wired in parallel to one of the Tang Band W3-881SI speakers so the load will drop to 4ohms for each channel. Both channels will be powered by the DTA-2 amp.1. Will this work correctly?2. Do I need a crossover?3. What can I expect in terms of sound quality?Thanks!
I would not run both of these speaker full range together. The sound quality could suffer. If you were to use a crossover (assuming you want the Visaton as a 'tweeter' and Tang Band as the Mid), you will have an 8 ohm speaker. The crossover over will separate the frequencies from the amp to the speakers. If you look the other way around, it also separates the impedance load (ohms) the amp sees. For example if you choose 5kHz as your crossover point. The amp would see the 8ohms of the Tang Band up to 5kHz and none of the impedance from the Visaton. As you crossover to the higher frequencies the situation would be reversed. So in total the speaker would be 8ohms.I have no direct experience with the Visaton, but have done a couple builds with the Tang Band. Might I suggest that you look at the speaker building projects Enda. All the heavy lifting is done for you for the design. If you still wanted a 4 ohm load, double the volume of the enclosure and mount two Tang Bands in parallel. Half the value of the inductor and resistor in the BSC circuit.Best of luck.
