4 x Peerless SLS-P830668 or 1 x SB34NRXL75-8 for musical sub?

Hello i want to build a music subwoofer ( bass reflex ) with tight articulate bass with good instrument separation and reasonable extension ( 35 hz ) and i can choose 1 x sb acoustics woofer or for the same price 4 x peerless ( sort of like Tekton 4-10 SUB , they will be 2 x 2 driver modules but stacked onto eachother ) . Will the sba be bested by 4 x cheaper drivers ? Are any downsides to using multiple bass drivers with slightly different parameters than one driver ? Looking at dibirama THD measurements the peerless sub starts to distort heavily below 60 hz compared to even SB34NRX75-6 which is worse driver than NRXL-08. Are there any alternative drivers for cheap multiple drivers sub ?
 
Hi, there are some things to consider. In case 2x subs are built, you have a luxury to place them at different positions in the room. This is almost always better compared to a single sub, since with two of them room resonances sort of equalize out to a degree. So, by placing at different locations sound output can be more even than what's ever possible with a single sub.
Second, with more area efficiency is incresed. Sort of free SPL.
Third, I have recently built a system with very similar peerless SLS 12" woofers in sealed boxes. Compared to other woofers I had tested distortion was low, and in general peerless SLS is a well built driver, especially for it's price IMO. It's better suited for sealed enclosures due to high Q.
Attached file with distortion measurement of whole system at 90 dB. Figure is excellent I think.

Regards

The SB will perform better overall, especially in LF extension and has lower THD. I've used both drivers you mentioned, so I can safely say the SB has the big advantage for use as a music sub, not just for home cinema purposes. Peerless also uses a small 38mm VC, as opposed to the 75mm VC on the SB.
 
I agree multiple subs will provide smoother low end response than a single sub. I'd however use different smaller drivers than the Peerless.

The SB34 driver is in a whole different league, especially in terms of musicality and distortion, but its not cheap. You get what you pay for.

At least consider using the SB23NRXS45 instead of the Peerless. The SBs are far more flexible for enclosure adaptation, much more efficient and just plain sound better by a large margine.

The main issue with the Peerless is the high Qts, limiting enclosure options. It sounds boring compared to even the SB23NRXS, which sounds much tighter and more accurate. The SB slso responds well to EQ if you want an assisted sealed design. The Peerless has limited power handling and less sensitivity, worsening driver performance when EQed to play lower. Its just not that great of a subwoofer IMO and not even that cheap. By far the best cheap 8" Chinese woofer I've used is the $45 Silver Flute W20RC38, which performs close to as well as the SB23NRXS45 and simply slaughters the Peerless 830668 in every way.
 
They're nice drivers with decent xmax and a fairly low Fs.....2 cuft tuned to 32 hz gets it done with a not so big box. Downfiring will reduce audible distortion at high output and also boost the low end......you might even get to 25hz in room with 4 of em.

If im not mistaken, these are 8 ohm drivers....so wire each pair in parallel box to box. A pro audio stereo amp with DSP from Crown or the like will get the job done.
 
Thanks for all the answers , so far i think i am going to have to splurge on sb34 .
I cannot have multiple subs around room due to size constraints . i can only make high tower out of them.

Hi,

The SB23NRXS45-8 has very bad distortion performance, not even close to SLS 10". Check this :

I would not even consider using such a driver.

lol my current woofers are SB23NRX , they are not that bad really , i can cross them up to 1 khz lr24 without much fidelity loss , but best they sound crossed at 500 hz.Between 100-500 hz distortion looks really nice on graphs.

looks interesting except for 4 ohm rating and it is not available where i live.

......

What do you guys think about Dayton Audio DSA315-8 12" ? Two of them are barely more expensive than one sb34 over here.
 
I want my sub to be able to follow fast drums and bass guitar without muddying them up , just like on my iems when bass guitar is lower in the mix i can still hear what is being played , but on my speakers the details are more blurred like i can hear that bass guitar is there and is playing something but detail is lacking... is this even possible for speaker system bo be more detailed and have better instrument separation than iems ?
 
Hi again,

I think with woofers like SB23NRX it can certainly be a problem with lacking detail if you feed them serious bass. So a good subwoofer or pair of them would certainly help. Of course, SB23NRX should be separated from low bass to reduce intermodulation distortion.
Now if we compare any loudspeaker system to heaphones, with speakers room reflections & resonances come into equation. It's huge factor. But IMO good 3-way speakers can come close to medium priced heaphones even with room acoustics, subjectively.
By the way, if you lack space, and want a really quality sub, there are professional options too. E.g 18 Sound 15LW2400 should blow the floor of any SB or similar hi-fi driver at similar price point IMO.

Regards

It's doable but difficult and costly.
The room/environment is at fault for most flaws you hear in your system. With IEMs, you have to account for inner ear resonances, however they are much more manageable. In return, the "being there" factor (soundstage) is almost nonexistent.

!0" JLAudio drivers do this very well. As does the 7" Wavecor driver. I enjoy programming drums and playing bass and love the detail and tone with these drivers. I have them in 40hz ported cabs. Soca and chutney have some wicked fast mix of drum machine and folk drums as well as a lot of Sly and Robbie material with very competent drums and bass
