What “under” means here
A price band has to be drawn somewhere, so we draw it on manufacturer list price and say where. This page is everything below $500. List price is not street price. These models discount, some of them heavily, and a model at the top of one band is often bought for less than one at the bottom of the next. We do not publish retailer prices, because a price we cannot keep current is worse than no price at all. Use the band to narrow the field, then check what it actually costs today.
We hold 16 bookshelf speakers in the database. 11 of them have a list price published by the manufacturer; the other 5 do not, and are named at the foot of this page rather than guessed into a band.
The 3 in this band
Polk Audio Monitor XT15
- Published sensitivity
- 86 dB, 2.83V/1m
- Nominal impedance
- not published
- Minimum impedance
- 4.1 ohms
- Frequency response
- 48 Hz – 40 kHz, no tolerance stated
- Type
- passive — needs an amplifier
What the published figures favour
- Minimum impedance stays at 4.1 ohms, so it is an easier load than most of this set.
- Manufacturer states a recommended amplifier power of 30–150 W, which many of its competitors leave out.
- Cabinet dimensions published: 269 × 165 × 182 mm, so you can check it fits before ordering.
What to check before buying
- No nominal impedance published at all, only a minimum. That is the figure needed to convert the sensitivity, so we cannot place it in the ranking.
- Frequency response published as 48 Hz – 40 kHz, with no tolerance stated. Without a ±dB window the range does not tell you how flat it is inside it.
Polk Audio Monitor XT20
- Published sensitivity
- 87 dB, 2.83V/1m
- Nominal impedance
- not published
- Minimum impedance
- 4.3 ohms
- Frequency response
- 38 Hz – 40 kHz, no tolerance stated
- Type
- passive — needs an amplifier
What the published figures favour
- Minimum impedance stays at 4.3 ohms, so it is an easier load than most of this set.
- Manufacturer states a recommended amplifier power of 30–200 W, which many of its competitors leave out.
- Cabinet dimensions published: 330 × 191 × 279 mm, so you can check it fits before ordering.
What to check before buying
- No nominal impedance published at all, only a minimum. That is the figure needed to convert the sensitivity, so we cannot place it in the ranking.
- Frequency response published as 38 Hz – 40 kHz, with no tolerance stated. Without a ±dB window the range does not tell you how flat it is inside it.
ELAC Debut 2.0 B6.2
- Published sensitivity
- 87 dB, 2.83 V at 1 m, full space
- Nominal impedance
- 6 ohms
- Minimum impedance
- not published
- Frequency response
- 44 Hz – 35 kHz, no tolerance stated
- Type
- passive — needs an amplifier
What the published figures favour
- Nothing stands out in the published data.
What to check before buying
- Below the median of this set once corrected: 85.7 dB against a median of 86.5 dB, so it needs more power for the same level.
- Published at 2.83 V into 6 ohms, which is more than one watt. Corrected to 1 W the figure falls to 85.7 dB.
- Frequency response published as 44 Hz – 35 kHz, with no tolerance stated. Without a ±dB window the range does not tell you how flat it is inside it.

What this page could not include
These bookshelf speakers are in our database, but their manufacturers do not publish a US list price, so there is no honest way to say which band they belong in:
- Klipsch RP-600M II — no list price on the manufacturer’s US page
- Edifier P12 — no list price on the manufacturer’s US page
- Edifier R1280T — no list price on the manufacturer’s US page
- Edifier S1000MKII — no list price on the manufacturer’s US page
- Edifier S2000MKIII — no list price on the manufacturer’s US page
We will not take a price from a retailer listing to fill that gap. Retailer prices move, and a band built on one would be wrong within the month.
