4 x PTT8.0X04-NAB-02 coupled 2 || 2 will give the same 4 ohm impedance seen from the amplifier. In 150L and simulated in open baffle eac

Then with the DSP, we make a Linkwitz Transform to give it more boost in the bass. Here I have boosted it down to 12Hz Q0.71 and shown the results with 2V peak on the speaker

At 7Hz, the system's response is reduced by 10dB compared to its response at higher frequencies. The maximum linear excursion at 2V and 5Hz is approximately 9.1mm. For simplification, we consider a response of 80dB at 7Hz in our calculations.

This analysis assumes an infinite baffle configuration. However, room acoustics, particularly the proximity of the speakers to walls, ceiling, and floor, can enhance bass response due to boundary reinforcement effects. Typically, placement near a single wall contributes an additional 3dB. Corner placement could provide up to 6dB, but conservatively, we estimate a 3dB gain, which is likely to be higher at low frequencies. This adjustment suggests each speaker could achieve 83dB at 7Hz.

Adding more subwoofers increases output. Each additional 4 x 8-inch subwoofer contributes a 6dB increase, assuming ideal conditions for coherent coupling. Therefore, incorporating seven additional subwoofers to the front array (totaling eight) would yield an output of 83 + (7 * 6) dB = 125dB.

Regarding power consumption, each 4 x 8-inch subwoofer requires less than 100W. Hence, a single 1ET400 amplifier per subwoofer is adequate. The default amplifier comes with DC protection at around 20Hz, typically implemented to prevent low-frequency damage to the speakers. This protection can be disabled if necessary, and a specialized version with this feature disabled could be arranged to meet specific requirements.

“ As pronounced and extended as the upper range was—no one would accuse this speaker of sounding dull—it was perfectly clear.

What struck me most, though, was the level of detail, particularly through the midrange. Vocals popped onto the soundstage with such presence and definition, they had a tangible 3D quality. The soundstage was so deep that during one of the Cowboy Junkies’ songs, Risbo, who’d never heard these songs before, remarked at the incredible sense of spaciousness he felt. I told him I had never heard such clean delineation between Margo Timmins’s vocals and the recording space when listening to this album through any other pair of speakers—at any price.

That intoxicating clarity graced every track. Performers were depicted sharply, distinctly, within the surrounding acoustic space. In clarity, the SPK16s were up there with the best speakers I’ve heard, which made me ponder high resolution. This term usually means a bit depth or sampling frequency (or both) greater than those of a CD (16 bits sampled at 44.1kHz). It is commonly believed that high-resolution files can store and reveal more musical information than CDs can. The recordings played during this demo were all in CD quality, yet the level of detail I heard left absolutely nothing to be desired. [Peter’s comment: perfect for Atmos music which is 48khz]

What else is in store for us with Purifi’s new 1ET9040 amp module aside from the promise of increased power and lower distortion over its predecessor? How far has the company come with their amplifier design? But it is the SPK16 loudspeaker that I found most intriguing. Purifi drivers are always of much interest, but this spectacular-sounding Purified standmount may well be the reference against which to judge other standmount designs.”
