So, on our list is a standalone graph(s) /w compare ability that has a sticky link so you can pass it around. shouldnt be too hard to add that now that we have all the core tooling built and data input into system, but im glad you brought that up.

I have  design going now that is 5 cubic feet. Uses a pro 18 and a long throw single PR. this is about the max you can do in that volume but can work well if you have a high BL , low Q 18 that can drive the PR. With a pro amp you can get some serious SPL out of that size box with that set up. Adding ports just becomes too big and if you go sealed you spend a lot more on power and driver(s)

Great price on this thing, really puts B&C in check there. My only gripe is, its more or less par for the field / meetoo product but at least they are undercutting the competition and driving price down.  The 18"  is really a bargain from PE right now, $340 :O

Post that data!

This is the platform for the new SVS ultra no? Is this a 15 or 16"? We need to get that new SVS sub. I'm dying to see how it does against the old one.

3 years, countless keyboard strokes, a lot of conversion work. But we got the new site up. We will add features to the new site over the coming months and bug fixes/ what not.

Most importantly the new site is much more readable, we'll have better photos ongoing and its got better tools for comparing systems to each other. Each system has a compare bar at the top of the page where you can query up another system and see them together.  I would really appropriate your feedback if you have any.

old site remains for a bit longer

Thanks!

We will replace old site some time in the next 2 week.

New one is here for reference (URL will change)

indeed, thanks for the link too @Alexlel

awe... maybe its a bassmaxx style where the driver is open on one side, other size is a horn. If thats the case, I can't see this 14Hz because of cancellation at long wavelength, but I don't really know

Looks like a ported box, not a horn?

Ok so it was an air leak that is causing the noise problem. It was coming from one of the un used t-nuts for the different drivers we will be testing. 

T-nuts don't really seal well, even with a screw in there, its not perfect

Ya, gonna be hard to guess at what that might be. Report back if they tell you anything.

Good news about your replacement.

Man - I'd buy one just to get rid of the orange halos on the iNuke knobs. They do look much nicer. The only gripe I have with the iNuke's DSP implementation is the 20 Hz limit. 

u love it, don't lie

But ya, if they created a 10Hz filter, its good game for everyone else.

Actually I don't think the new ones need a fan mod. So not only are they MUCH better looking, but in the short time I've played with one, I have yet to hear it ramp up. Granted there isn't any boost/eq of any kind down low yet but my friend is running 8 JBL CX1200's on one and we watched demo scenes and music at close to reference with known heavy and low bass and the fans never once spooled up.

Then again maybe they're broke...🤔😂

lol @ last line, 

either way, at least they are quiet

Could be a leaking surround, you would be surprised what they sound like. A ticking noise is not out of the question here. I can't say anything for sure but I do know if there is not enough glue on the pro cloth style surround, it can permeate air. It can be fixed with more glue applied right on top with a brush.

This might be the right stuff. I just did a quick google search so don't take my word for it! You need a little painters brush to apply on top.

Poor mans iTech 6000!  But the new fascia for these amps looks super high end, much better than the nukes.

On paper, that looks like incredible value. Did the inuke have DSP too?

Probably needs a silent fan mod like pretty much everyone else they make tho.

Is the magnet the top ring or the lower ring? Is one of those rings steel? I'm confused. Both look HAF (Huge As ***) Seems like it would be the top ring as I understand the B&C driver is an overhung gap so that ring can't be a gap plate... too tall!

Been almost 3 years in the making. Huge undertaking. Just finishing up the last few features but we're closing in!

Here they are!

 

Nice so are you switching the driver out to the iPal?

https://www.cnet.com/news/the-case-against-subwoofers-for-music/ (watch the video)

I think there are 2 problems

1.  people let subwoofers exaggerate low end and more or less ruin music. The same can be said about headphone bass boost (mostly just sounds like crap)
2. lots of music does not contain subsonic content or even low end audible bass.

I don't fully agree we can omit a sub for all types of music, especially modern style music which often has subsonics, but then again, this is the right place to really find that out.
We know movies need subs but which songs need it too?

^ Just bought 3 pairs.

meanwhile, I have a wife and 2 kids that turn down my single 12" sub if the receiver goes past -28dB.

**face palm**

i hate you guys.

So, joy of joys, I'm going to have to move house in the near future.

 

Currently in a first floor apartment, I got my (handle-less, veneered) 11 cubic feet, dual-18" subs in using sheer grunt, with me and a friend taking bottom corners and walking them up the stairs.  IIRC they weigh about 15-16' each, and they have nothing to actually grab hold of to move them (bad planning on my part!).

 

However, since then I've slacked off from the gym for ages and am now weeeeeak, and I fear we'll drop them down the stairs and/or do me an injury if we attempt to carry them out.

 

Has anyone got any recommended moving techniques / equipment?

 

The missus alerted me to these, which are apparently rated up to 650lbs(!):

http://www.uscargocontrol.com/Moving-Supplies/Moving-Straps-Mover-Bands/Teamstrap-NEW-IMPROVED-Furniture-Moving-Straps

but just one single strap underneath seems to invite whatever you're carring to slide out to one side, especially when it's 200lbs+, very dense and very smooth-surfaced...

 

The only other option appears to be one of those stair-climbing trolleys:

https://www.amazon.co.uk/Costway-Wheel-Truck-Trolley-Climber/dp/B07676YF5S/

https://www.amazon.co.uk/capacity-trolley-extendable-OT1001-REVIEWS/dp/B00Y3PAD1O/

but the main issue with those is that the subs are too wide to fit down the stairs sideways, meaning only about a third of the box is actually on the bottom tray when it's on it long-ways, making it very unstable and near-impossible to get it leveraged off the actual ground!  Perhaps they would be ok with the box tightly strapped to it??

 

Any recommendations very gratefully received!

I for one am firmly now under the philosophy of cutting up subwoofers into smaller ones and just using multiples.

2 single 18's vs 1 double, etc etc.

or 3 12's vs one single 18

sorry, that does not help you here

Yes. Unfortunately VC mag tested almost every other B&C woofer but the Ipal's. For some reason the 18sound Klippel tests always seem to have a bit more variation than the B&C's. Still it's a nice driver and came in at about 13mm xmax which is only 1mm under their 14mm spec.

Those liars!

Displacement can be leveraged from cone area so while the xmax is average, overall displacement is still pretty damn decent at 5 liters. Josh, what is the SPL@1 watt? 100dB? To put this into perspective, a 12" high excursion woofer needs an xmax of 50mm to match this, and it won't have anything close to 100dB @ 1 watt.
