Good front stage speakers can be under $200. But to get realism it cost more. Treatments, a DSP is a must, and hours of tuning with a RTA and playing track after track.
You will never have a good front stage without a DSP. It's more then T/A and a mono EQ. You have to match each side of the cars response. But a DSP doesn't have to cost much. A mini DSP will do the job. Then it's all on the tuner.
Those that show up in the lanes that think higher priced gear matters go home with a big L. Those that know how to run go home with a W.
