Yes I know, definitely the hardest choice, they sim exactly the same in the Othorn. Here in France the best price I can get on the 21DS115 (same price for both versions) is 383€/unit. The LaVoce SAN214.50 is at 353€/unit. Do I prefer to save 30€/speaker or do I prefer to trust B&C quality ? Can't find that much reviews about the LaVoce speakers, if I really want to play safe, 21DS115-8 is the way to go. But Josh testing seems positive about the LaVoce. Maybe if he see this he can share us his thought !

Alright, I think it's going that way ! I'll give a try to the LaVoce then. There are some advantages I can actually see : - If one day I get a better amp and build 2 more Othorns, I can put 2 of those in parallel per channel - A little bit cheaper - Less stress on my cheap amp with 8ohm operation, less power consumption as well - Better impedance for my cables, less signal loss (got 20meters of 4mm²/AWG11) The only disadvantage I can see is that the speaker will only have 1200W available (a little more on crest, 1500W measured) but it's way enough, Xmax is out at 1700W, it's a 1.5dB loss (2dB compared to a 21DS115-4 with 1700W). And as Josh said in his review : I'm not losing that much by not sending 3400W peak into it, avoiding distorsion, power compression and motor noise. If I want more output I'll go for more cabs ! Thanks for your time NiToNi, I'll make a post when everything will be tested !

I didn't made those tests myself but I read a lot of reviews about this amplifier, it can do 2.6ohms, some people even pushed it to 2 ohms (4 drivers per channel, PD154 in HD15 if I remember well). I did exactly what you said before posting here ahah, forgot to mention it, in Hornresp, 4 PD154 in HD15 in parallel gets to 2.4ohms. But I was thinking that maybe, driving 1 speaker at 2.2 ohms would be easier for an amp than driving 4 at 2.4 ohms. I know it can do it but how much time ? I can get the LaVoce SAN 214.50 30€ cheaper maybe I should give it a try ! Less output VS caution, difficult choice.

Hello ! A quick question about the 21DS115-4, I'm gonna build at the end of August, 2 Othorns loaded with 21DS115-4. But I'm a bit afraid with the impedance curve shown by Hornresp, it's around 2.5ohms on the whole Othorn bandwith, going as low as 2.2ohms, will the reality be the same ? I'm gonna use a Proline 3000 at the beginning which isn't really built for 2ohm operation but easily does 4ohm all night long and can survive to 2.6ohms (driving 3x 8ohm speakers per channel but not recommended). Should I try it or should I go for the B&C 21DS115-8 or the LaVoce SAN214.50 to be careful ? Already got the amp by the way ! They sim well, both close to the B&C 21SW152-4 but less motor force than the B&C 21DS115-4

Hello ! I just saw the Ricci's post on the Skram topic, it seems like the NX6000 could power a pair of Skram, would it be enough for a pair of Othorns (21DS115-4 loaded) ? Here, in Europe, we have the Proline 3000 sold by Thomann which is enhanced on the net thanks to its price (600€) and its performances on subs but its almost 2x the price of a NX6000 and 35 additionals kilograms. What would be your bet ? The Proline 3000 has been measured at 1800W/4ohm continuous instead of the 1500W announced. Could the NX6000 follow up on huge deep bass lines ? For an entire night ? Thanks !
