i've been working on a two18+amp700+amphion cables for a month now and i usually work at like 60-70db, occasionally 75db. probably been playing for 100+ hours by now.

the problem is, my pair is mad bright and it shows even in measurements, theres a +4db bump at 12k-14k and a narrow +6db peak at 20k.
before this, i had a 2018 demo pair in the same room that's been played for like thousands of hours and it sounded so nice and smooth compared to the new ones. we even tried hooking it up to my new amp and cables - still, sounded much rounder with ​no signs of harshness. they measured with a small +2db bump in the 11k-15k range and no 20k peak.

so, could this be a break-in thing? should i crank them to 90db and leave them play for a week and hope the high end smoothes out?

any chance something was changed in the design since 2018?
or did i just get unlucky and bought an overall bright pair of two18's

thanks!

Well, the most affordable option is to just supplement with some inexpensive subs. The typical cheap subs (the JBL LSR310s come to mind at something like $420 US each, depending on sales) go down to 27hz according to JBL specs, but the crossover is of unknown quality. Designed to work with powered monitors that often sell for $200 US each.

There are a range of home theater style subs that will let you take a speaker level feed at your monitors and run that into the subs. You have to dial in your crossover point and level. Sometimes just a little bit of extra extension is what you want. I was looking for more radical results, and I got them, but at a price!!!

For your purposes, how affordable do they need to be?

My price will be up to 1500 euros

I already own a pair of Genelec 8351
Do you think the 7360A Genelec subwoofer could also work for my Amphion ?

I am sure it must be possible to find a good subwoofer fiting well with the One 15....but Which one ???

I guess DigitalGrease uses those.

And all-in crossover would have been cool. Cut One15 at 120hz for example, with the sub auto aligned to take over.

I'd not mess too much with either the limited controls on the 9S, or the ad-da and dsp of the 18S (as DigitalGrease mentioned), but rather crossover with my interface's digital eq slots of the outputs,+ maybe phase, and sample delay.

Can you explain more ?

Pretty sure I was looking at this model which is about $1K for one.

The standard shipping method for kits to overseas is postal service. The standard power cord is the US version. We don't plan to supply region-specific types. We encourage overseas customers to buy their own power cords and factor in the cost in their budget. "

SUBWOOFER PROS:
No Euro dealer, Brad Lunde told me to check Helios in Holland, but no luck.

Looking to get a pair of One18's. Not settled on what amp to get. Missed out on a 2nd hand Amp100 for $600. I see a lot of guys use the Adcom GFA 545 with the Jim Williams mod. How do you go about connecting this up since it doesn't have XLR inputs?

Looks unappealing but it sounds insane!

I really hate subs in general and their integration, but Flexbase is a smooth extension. Plug and play: mess with the crossover, volume, done. It's mad the way it feels like a super calibrated system when I just opened the box, set stuff up where I can and hit play.

It seems to take my One15 more towards high-end headphones territory, meaning ultra clean extension down low and even more superb mids.
The funny thing is the voices seem lifted and more palpable, and the snares have better focus/transients.
Clearer phantom center.

I'm already super pleased how it performs in a "bedroom" set-up. I may be lucky with the room as well, the bass is deep but dry and "controlled".

I'm just starting with Flexbase and it already sounds superb. Cheers
