Am attempting to hold back for some of the more seasoned and experienced attendees to post their thoughts. The reviews are being filled out and there are several posted now with details. Since some of the reviews are done I'll give the Rythmik my thoughts here now though. (prolly copy and pasted to the GTG thread soon though)
I ran it one port, 14hz, low dampening, rumble off, limiter on, PEQ off, LFE in. As I said, I knew it wasn't going to SPL out subs that cost double+, especially when they are being shown as co-located duals + a triple, on top of that (hard to price compare the passive caps though). I tried to show the FV15HP's strengths. First the quick positive, in the order we went, (minus the HSU ULS as I only heard 1/3rd of it and was still getting my bearings, and loved what I did hear... but didn't have anything to gage it on and didn't hear enough to compare. I heard a tad and was very impressed)... In the order we went, this sub was the first IMO to have deep impact, to wow people, to move a lot of air, the folks peppered up quick and were excited. Very positive response.
The material was designed to identify limits and it did. Two points that can easily be interpreted as negatives occurred during the FV15HP demo. I personally do not consider them negatives of the sub, be aware of what ported subs do and do not do. I'm going to be harder on my sub than the others. Let's call them issues, as I said I do not personally consider them negatives.
Issue 1) 5hz to 100hz sine wave boosted way above the level of the other material long and slow engaged the limiter quiet a bit until port tune. 5 hz - 15 hz was not a tiny amount of time; that sweep was slow and CRANKED, which was good, see what the subs can do. For me the limiter protected the sub, ported subs do not play below tune with power, 14hz flatish (slight room bump around 30hz ish) measured at the GTG, down to 10hz in my room (according to RS meter so who knows what that means). It was awesome above the tune and the hardware protected the goods when trouble signals were passed to it.
Issue 2) I'm only sure I heard it on Pulse, but there may have been one other time (in addition to the long slow starting at 5hz sweep), we did achieve port noise. That pulse clip is way below tune. The material was straight brutal.
Both issues can be easily resolved, I think the sharper roll-off (med or high dampening) would have prevented any issue. I could have asked for the minidsp roll-off at or slightly below port tune. Then the two "identified limits" would not have been heard. Those that understood what the two events were, knew what the two events were. If I had run through the material prior, I could have optimized the results, but honestly I'm glad we showed what it does and does not do.
I do dabble at reference occasionally and play at -10 to -5 fairly regularly and have never engaged the limiter or caused port noise in my home. Also not sure if this has been said but the gain structure, recording level, levels in general, and how hot we ran the subs was not to reference. The subs were level matched to each other though, minus the SVS. We think either -8 or -10 db at the GTG was reference for the subs. Therefore "0" in this GTG speak is crazy and we saw some "+" numbers.
The FV15HP did awesome, so tight, so smooth, handled everything above tune happy as can be. I was cranking it on material without sub 10hz material and could not make the limiter engage again. It wanted more, sounded very smooth and tight, and impressed greatly. It had serious impact.
One LMS ultra 5400 woofer I believe is 900ish (no box, no amp, not delivered), dual ultras came up quick after that. Material from the ceiling fell on my head before knocking a bass trap off the wall almost wrecking a speaker (incredible save Austin popalock) during the dual captivators (they tripped a 20amp direct to box line and two breakers on the amp, I think there was 5000ish for real though watts being pushed there), The dual submersive + f2 demo had 6 sealed 18's. WOW. No the Rythmik did not out do SPL wise any of these, nor did I think it would. But, it did very very well IMO, I am still very pleased with my sub, and I'm very proud of how well it did.
On an off the wall point I did find important (suspect others may find irrelevant, maybe) Jeff from JTR was there as well as Mark Seaton. I was super impressed that while demo'ing their gear together, they were not only super classy about it, they appear to me to be friends with great respect for each others products. Their products are in the same market share IMO. In bringing up the Rythmik Mark said some really great things about Brian of Rythmik. Super high quality, super high performance, super high value. At this price point it is the best out IMO, but not only MO. For my situation and ultimate goal for duals, this was by far the best choice.
1 FV15HP compared to 2 JTR captivators for SPL and impact, nope obviously, but I knew that just reading the graphs before the purchase, was super fun to experience soooo many great subs this weekend.
The E15 owner (thanks for the help S) wasn't happy with how he set it up and had some PEQ going. I thought it sounded great and the folks at the GTG were singing praise as well. It has a tad more impact in the reserve then we got out there, but it did awesome. S, did you read what Gorilla's dad said about your piano black?
