ADS L1230 Speakers: A Must Read Review

A set of ads l1230 speakers is extremely rare. If you’re familiar with a/d/s/, you’re aware of how uncommon these are. The L1230, L1530, and L2030 have been described as having a euphoric sound. The Kimball Piano Company made the cabinets for the L1230, L1530, and L2030 and their incredible sound quality.

I’ve never owned a speaker that has images as well as the L1230. It belongs in the same class as good electrostatic speakers, but without drawbacks.

You will not be disappointed because this set of L1230s is in excellent working order. The sound-stage amplitude and tone are both well-balanced, with a sweet, soft, and well-defined mid-high.

Features of ads l1230

The ads l1230 tweeter is an entirely new architecture, featuring a 1-inch parabolic-dome radiator bordered by a phase plate that is taped and molded, contributing to the tweeter’s extraordinary dispersion characteristics.

(Also, the tightening screws are slightly raised to prevent possible diffraction from affecting the tweeter’s polar pattern.) The tweeter-woofer crossover occurs at 1800 Hertz, with a three-pole high-pass filter section below that frequency attenuating the signal to the tweeter at an 18 decibel/octave rate.

At 900 Hertz, there is a reduction of the tweeter output by 21 decibels compared to the region of flat-response level as per ads. The crossover model allows each driver to function at maximum efficiency within its frequency range with the least amount of damage and risk

. Switch enclosed into the back of the box close to the input cables and a protecting-fuse bearer is a unique feature of the ads l1230. The response of the advent speaker is initially “flat” in the usual spot of the switch. The output in the 2-octave scope centered at 2000 Hertz is reduced when the switch is set to the background. The response characteristic will allow the traditional music to play at a small sonic mask of the dialogue.

It has a typical sensitivity of acoustic suspension, of which the rate of the sound pressure is 87-decibel units. The unit is measured at a distance of 1 m when it is driven by a 1 W. The size of the cabinet is a height of 26” and a depth of 11 inches. The cost is $200.

The ads l1230 Measurements

It has a crossover frequency of 1800 hertz. The switch’s original position at the back of the ads l1200 almost 2-decibel units amplified system; the affected frequency range was 1,000 hertz to 4,000 Hertz in any of the switch positions. 60 Hertz produced the most woofer output. From 35 hertz to 20,000 Hertz, the speaker’s reinforced response is a little over 4-decibel units.

Up to almost 16,000 Hertz, the distribution of the ads l1230 tweeter is virtual and great over the regular hearing region, without a noticeable effect in response measurements from the left speaker and the right speaker. From 16,000 hertz to 20,000 Hertz, there was only a minor deviation. We can’t recall ever measuring a front-radiating dome tweeter with the same distribution as the Advent design.

The distortion of the woofer is too low at the 1 W input level. The distortion, 0.32 percent to 0.58 percent at 40 hertz from 100 hertz to 50 hertz and 22% at 40 hertz. When the drive level increases to 10 W, it gives a distortion of 1.4% to 80 hertz, 2% at 50 hertz, and 6.3% at 40 hertz.

The impedance of the speaker reaches 24 ohms when the bass resonance is 46 hertz and 21 ohms at 1250 hertz. Its most negligible value is around 6ohms at a range of 100 hertz to 150 hertz, and around 7 ohms at many f that are above 2000 hertz.


If placed/appropriately positioned in the room, those l1230 speakers have a very solid/tight bass. Experiment with different distances to the sides and behind you. Use longer spikes and anchor them to the floor through the carpet if they are directly on the rug. If they’re on hardwood, use spikes, but make sure there’s something between the spike and the floor to keep them from slipping.

Many people here swear by Herbies’ products and have had good results with them. You won’t need a subwoofer if you want to use those speakers for home theater and movie sound effects.
