How would you think they add up then? It's designed as a top cabinet only, and clearly states it's not fully hornloaded down to 80 Hz.

I mean it’s gutless in the band it’s designed to work in!

i think we (intended as most operators on this forum, but with due exceptions) are used to a different sound, with a more prominent bass than most people on psw and soundforums, who usually gather more to rock or other live genres with less bass buildup.
another example is danley sm80, it gets a lot of praises for live but i doubt anyone here would use a 140hz top without a dedicated kick for a heavy dancing night. so maybe gutless is just too flat, good for faithful reproduction, but doesn't kick like a mule. maybe i remember wrong, but wasn't element audio using pm60 on the sides on a carnival float this year, but with added kickbin guts, so with a highr cutoff? if so, anyone can comment on their sound in that enviroment? |

Good point but my main bag is rock/live and I still think the 12” section of them is entirely useless 😅

care to get into details "RoadRunnersDust"? Which Setup have you tried, what is it that you missed 100-600hz, do you know of a similar sized option to cover the passband better, more efficiently in the same size? curious what exactly you mean with "gutless"

Sure "bass*en*mass"
Sat on top of a pile of 721s they consistently sounded like they may as well not have been there. No punch or impact in the lower end of their response and for the little you could hear of them as they approached the crossover to the BMS they sounded very boxy and thin. Not made any better with a couple of 215s between them and the 21s. As far as a different option for covering 100-600, no. It's tricky to compare something that simply doesn't work to an effective solution. As far as a nominal "upper-bass through to central-mid" bandwidth goes, they'd get absolutely annihilated by a pair of 12" Flood Low-Mids. |

Sounds like poor alignment of a ported horn LF section with a bandpass horn to me, not very complimentary phase before you add filters for a start.
They’re not gonna kick you in the nads but they’ll have a snap and there’ll be some LF content for warmth. Again, better crossover and alignment helps make that shine. Edited by toastyghost - 31 October 2018 at 1:37am |

Fair point, Kyle.
Even on their own with the BMS they just sounded a bit "not-there". Obviously disparate levels but on a even-tonality contest even an Sx300 would run down to 100Hz more convincingly |

As I already had a big pile of 12NDL76 doing nothing, and already am using 4594HE in my boxes I've had a mate build me a PM90
So I can see for myself whether it's actually good or not

I tried a couple but i never got a ported midbass horn to work and sound nice, also as Kyle mentions there will be steep phase distortion at the lower end of there pass band which could make alignment quite tricky, i would try very steep 48dB/oct filters so there is as little overlap as possible as the phase response of the turbos and PM60s in that range will be quite different, so best to align them over a narrow band to minimise any destructive interference.

EAW KF850 has 15” horn section that will cover that range, Pete 'Nova' built his equivalent of the 850 with 2 x 12’ s facing each other, similar to the early Martin 215, Pete's approach would probs be worth exploring although he ported his to use as a one box solution but doesn't have to be ported. If you are OK with horn response then it shouldn't be too hard to build a box that will give a second order Butterworth type response HP roll off at 90Hz that you can tune to LR4 with a B2 at 90Hz

Yes roadrunner they were, and some other copys as well. Going to get some usb2's this weekend then will see what, if anything, I want between them and the sls920's. Only really tested the 920's at home so far, but found they get a bit honky up to 200 when the bass gets driven on the mixer. On the other hand I've read about people using them well with just usb2's so will test it out before getting MORE speakers :)
Might be after some more sls920's if all goes well, if anyone has any they want to part with? Thanks for any info as well guys, newbie trying to find my way.
