TBT: SVS SB-2000 Active Subwoofer Review

At times I must come off as some sort of audio-curmudgeon, such as when I became upset when I noted some audiophiles calling a component a preamplifier rather than a line stage. There have been other times, too, that I've gotten upset over someone using what I consider the incorrect nomenclature for an audio component or part. Thankfully, I've gotten over that preamplifier versus line stage episode. But I'm still working on the fact that some sell speakers that they call "subwoofers" yet don't go below 20 Hz. "Sub" what?

TBT: Wells Audio Commander Level II Vacuum Tube Line Stage Review

A little while ago I reviewed the Wells Audio Cipher. I asked Jeff Wells, the owner of Wells Audio, to tell me more about the Cipher, and he more or less described it as his preamp circuit, with a single fixed input coming from the DAC. I was so impressed with the smooth analog nature of his DAC that I asked him if I could review his preamp. A few months later, a Commander Level II arrived at my door. The Commander Level II is Jeff Wells' mid-range preamp. The standard level I, sells for $3999, the level II (my unit) sells for $9000, and the Level III sells for $18,000. Each version has the same base design and circuit, and each upgrade introduces higher end and more expensive discrete parts into the build process. According to Wells Audio these improvements lower the noise floor, increase the dynamic range, and dramatically improve the experience.

Can subwoofer arrays be configured to provide more even bass distribution in outdoor venues?

Subwoofer arrays can be configured to provide more even bass distribution in outdoor venues by utilizing techniques such as ground stacking or flying the subwoofers. Ground stacking involves placing the subwoofers on the ground in a strategic pattern to maximize coverage and minimize interference from the surrounding environment. Flying the subwoofers allows for greater flexibility in positioning and can help to achieve a more uniform bass response across a wide outdoor area. By carefully planning the placement and configuration of the subwoofer array, sound engineers can ensure that the audience experiences consistent and powerful bass throughout the venue.

What is the optimal placement for subwoofer arrays in a concert hall to achieve maximum bass impact?

The optimal placement for subwoofer arrays in a concert hall to achieve maximum bass impact depends on various factors such as the size and shape of the venue, the acoustics of the space, and the desired sound coverage. In general, placing the subwoofers in a central location or in a distributed array configuration can help to ensure that the bass frequencies are evenly distributed throughout the venue. By experimenting with different placement options and adjusting the settings accordingly, sound engineers can fine-tune the subwoofer array to achieve the desired bass impact and coverage for the audience.

How do line array subwoofers compare to traditional subwoofer arrays in terms of frequency response and dispersion?

Line array subwoofers differ from traditional subwoofer arrays in terms of frequency response and dispersion.
