## Questions & Answers

**Q: do they have to be in an enclosure or can they play free-to-air?**
A: I have not heard of many cases where speakers like these play free-to-air. Most speakers are designed to use an enclosure to get the best sound quality. I have seen videos of unique "open space" panel speakers but they are rather unique.  If you go to https://www.diyaudioandvideo.com/   you can use their utilities to determine the best way to create the enclosure based on the measured parameters  of the speaker (e.g. sealed vs. ported).

**Q: What are the mounting hole dimensions, i.e. Distance between holes on one side?  I need to match a speaker with 3 13/16" inches between holes.**
A: The measurement between holes is 3 1/8".  The measurement from one hole across to the opposite hole is 4 1/4".

**Q: What's the lowest frequencies they can produce?**
A: According to the specification sheet (which you can download from the manufacturer's website) this speaker can go down to 55 Hz. This can be manipulated somewhat by using a ported tube and adjusting the length.

**Q: Could this work as a sub replacement for a Logitech z509?**
A: Yes. This sub makes a good replacement for most PC 4" PC audio subs. Please make sure that your old speaker was 8 Ohm

## Customer Reviews

### ⭐⭐⭐⭐⭐ Awesome sound
*by J***N on March 26, 2026*

The sound great was replacement for Altec Lansing speakers that had dry rotted.

### ⭐⭐⭐⭐⭐ You can’t go wrong with Dayton
*by U***" on November 27, 2025*

Great little speaker. Delivers great sound without the price tag of TangBand

### ⭐⭐⭐⭐ Great Midbass for desktop DiY speakers.
*by M***F on June 18, 2026*

I choose these for the price point for a 2.1 DIY PC system. I did test them with a 3 way pre built crossover, not very booming. They don't distort or sound muddy at full volume with the Romicta preamp in picture. Also using Dayton's 1" dome tweeter which is very clear. Enough sound for your seat, and it doesn't disrupt the whole household.
