Hello Alex, you are welcome to come and listen to mine, may be a little bit however as my daughter is pregnant (she still lives at home) and is due any where's within the next week or so but after things settle a bit no problem.

Wow congrats! Sounds like a very exciting time. I will absolutely take you up on that offer when things settle down. Love that drive up the coast!

Seriously. Look at this sh*t. The 215 is in light blue in all of these. From 20 hz and up (more like 17 hz actually) these are unreal. How many of you guys with 215 have been motivated to get a more powerful amp(s) for them since the measurements?

215 vs. Cap 1400

Here's a bassheads attempt to nudge a few 215RT owners into giving these speakers more wattage so they can really shine.


First off let me say that going into my amp testing of the NU4-6000 I wasn't expecting much but this amp pleasantly surprised me. It held really nice power all the way down to 5hz and took all the testing in stride. It never power cycled or muted, and also ran cool to the touch the whole time.


Second, the DB numbers lost going from a bridged K20 to an iNuke I'm showing below are conservative for several reasons, the most important being that the wattage numbers are only for a single channel driven. Once you're driving both channels into 4ohm loads on an inuke3k or two of four channels into 4ohm loads on an nu4-6000 the numbers only go down.









A doubling of wattage = 3db. A doubling of both the speaker and wattage = 6db. Going from (1) 215RT to (4) 215RT with 4 times the wattage = 12db.


That means from 50hz and up, if you're using a NU4-6000 not even (3) 215RT will match Ricci's K20 numbers for a single 215RT. At 100hz and 125hz, not even (4) 215RT will.


Food for thought

^^^^^^

BTW, that also means that if Josh used the NU4-6000 (in stereo mode) or iNuke 3k in stereo to test the 215RT, it would have lower SPL numbers at every single frequency vs. the Cap 1400 and its built in 1,400w amp.

Yeah, DD posted that about the Cap 1400 having more than a 215 using non nuclear power. Or, you could think of it as the old passive Cap with Ricci's amp would have more output than the 215 on Ricci's amp.

All of that information goes out the window in my brain when I see those little lines on the graph next to each other.


Luke, have you happened to test a Crown 4002 xti? I'm using that now and noticed that it didn't clip as soon on the same sections of songs and movies as the inuke 6000 dsp so a lot more power than the inuke 3000 dsp I was using. If you have, how many db's down would my setup be from Ricci's amp?

I haven't tested that one, but just by looking at the specs (and Crown's spec are pretty accurate), you can add at least 3-4db to the inuke 3k's numbers.


The 4002 looks to have more power in 4ohm stereo than the 3k has in 2ohm stereo. Looks like a stout amp.

How about with a bridged CC4000?

Those numbers on the K20 are max output. We don't know how many watts he was feeding the 215RT's do we?

Absolutely love my 4002 xti and my 215 RM's, Match made on heaven. I can only imagine how you 215 RT owners feel.

I can eq the bass to the moon and still play almost any bass heavy music I want +6db over reference.

A bridged CC4000 will be 6-7db higher than the inuke 3k. However, the K20 and even a bridged CC4000 can get the 215RT into trouble (excursion limits) below 30hz, so it's not recommended.


Since Ricci took an impedance sweep and also noted the voltages used for each max burst reading, we actually have a pretty good idea of the wattage used. Take a look at the columns highlighted in blue in my post from a few hours ago.


Now, impedance will typically rise slightly as power goes up, and the impedance curve will also slightly change, but it'll still be fairly close to what I posted.

What about a bridge PLX-2502? Or a D-sonic M3-600M?

Crown XTi4002 is a nice amp.
I used a pair on my passive Captivators for 3 years and they never ran out of steam.
Quiet fans as wel.

I had the Powersoft K3 on my subs very shortly.
Due to not excessive , but in my small room noticeable , fan noise I got a great deal on a pair of Powersofts M20D.

I already have one and these are very quiet under reasonable load.
The pair will be in bridge mode so 2400W for each Captivator.

Still want the S1's but now I can offer the passive Caps with great amps.....or keep them in case the Caps are sold..
