The Ultimate Sealed Enclosure - 140db SPL Score - With Only 1,000 Watts - Part 2

[@meade916]

a PR setup should always have double the cone area of the actual sub being used. If you doubled those PR's it would actually perform a lot better than it does. Just one of those subs with both those PR's would be Ideal. Just a little tip for next time...looks cool though! Looks like it's slapping hard as well. edit: just noticed the AMM-1, hell ya! badass!

He did a single sub with two radiators in another video (140 dB with 1000 watts), but two subs with 4 radiators would be ideal. And of course your shop system was slapping hard!

[@jaz97]

I thought was double the displacement of the woofer not so much the cone area. So if I PR can move x2 the air of the sub it's fine.

I have 6 cheapo Kenwood Road Series 250 watt RMS subs in a sealed enclosure on a "500 watt" Rockford Fosgate amp and it does 145db. Each sub has its own chamber in the enclosure. Can't wait to run em at their rated power. 😆 NVX subs are pretty cool. I love the chassis on em. I've got two that are blown that I'm going to make into a couple of monsters when I rebuild em.

Recently I created sort of an experiment sub box. At the time, the slaps were super expensive (they've been going from $40-100). So I bought 2 cheap 12s and removed the magnets. Created my own mount (2"pvc) to the voice coils and weighted them properly with metal washers. Did some testing to get the frequency where I wanted it. This setup of an Alpine type R 12", the 2 12" radiators, and 400W really surprised me! And the low frequency response is crazy with the Epicenter! Out of curiosity, same setup but with a much cheaper Kenwood budget 12" sub. Still amazing results! Next experiment was the Alpine 12" type R in a larger vented box (1.5cuft) vs the kenwood 12"/radiator setup. The radiator box wins no contest! So the

@BudgetBassHead- Im so glad you took my suggestion, and used a pair of active subwoofers, with a pair of these Earthquake Slaps units! These Slaps passives are unlike any other passive radiators i have seen. 99% of most people think you need to have 2x the cone area, as a passive radiator= false, the passive needs to have @ least 2x the Total displacement. So 1 of these Earthquake Slaps passives will work, as long as the 1 active woofers Total X Max, is 50 Mms or Less. These babys perform Awesome, and in such a tiny space! Great video, and Awesome Db score 🎉, plus bandwidth seems great as well!

Glad to see you've doubled up your last enclosure, though would have thought 4 passive radiators would be better. You'll have to stick the weights on though or the tuning will go way up. Though with 100mm Xmax (is that peak to peak?) the single passive radiator might suffice.

A good alternative to the NVX is the Dayton max-x driver's. The Dayton max-x driver's have great cone area excellent x max. And fantastic motor force. Built a 2 10 box for them and they work amazingly well and they are taking easily double rated RMS. I am lucky to ride share with the guy that I built them for. He sends them to limit often and they sound great. And they are very affordable.$110for the 10. $150 for the the 12 and $180 for the 15. I had the 15. Very good driver. Needed space back.

Hey budgetbashead I'd love to know your thoughts on equal passive radiator cone area to activate versus double passive cone area to activate like in the other video. Thank you for your videos.

[@BudgetBassHead]

A plan to do a follow-up video and test that theory.

[@evilinside5984]

@georgepearsall1817- Most people think you need 2x the active cone area, for the passive radiators to work right. Its not 2x cone area, its @ least 2x the Total displacement. These Earthquake Slaps are unique, because they have over 100 mm of Total X Max! So as long as the same diameter active speaker, has a Total X Max of 50 mm, or less, 1 per active, will work great. Other companies ive seen that make passive radiators, have such little Total X Max, that they require 2 passives per 1 active driver. This is where the Earthquake Slaps units are leaps and bounds ahead of other passives! As far as sound/preference goes, Passives perform= higher Db scores, but sound like sealed enclosures, you pick the tuning freq. with the combo., of air space provided, and the amount of Mass put on the Slaps units. Smaller airspace= more boom, less low freq. extension, bigger airspace= Less boom, but more Low freq. Extension.

[@twinkyunouwantmycreamfilli8297]

Ive always heard that the passive radiator works well being one size larger . Like, 10 inch sub with 12” radiator, or 12" sub with a 15" radiator.

@17:00 ...2 options: obviously use 2 separate terminal cups on the back of the box (1 for each chamber) OR, use(non-galvanized) bolts through the divider wall inside the chamber to run the signals internally. You could probably still do the 2nd option pretty easily if you still have the box.

Can we see how a shallow mount, with a PR would perform? I am still searching for more DB’s in my single cab F250.

[@ZoeyR86]

With passive rads, the rule is an 8-second minimum your losing efficency if you press a rad it should take a minimum of seconds for the woofer to drop back down this is maximum leakage recommended to prevent the rads from over extended during long bass runs. You seal up the box properly and your going to see .1-.3db gain and a slight drop in fb3. I had 3 of those eq rads on a 3.2³ft box with an avatar stu 1546 d2 and did 147.3 at 39hz. With the rads invert mounted for tuning weights. You really want to tune the box so you can use as little weight as possible as the more you add, the less power handling they have at lower frequencies. Also I compound 6th order with a small sub and large rads and be insanely efficency. I used 2 6.5in subs in a 6th order with 2 of the eq 10in raids 1 on each chamber with a 2/3 ratio and tuned to a 58-28hz bandwidth and is was stupid 142db on 980w rise to 1.74ohm

[@TimpBizkit]

I was thinking about 6th order with passive radiators, but using a slot port for the high tuning and a radiator for the low tuning, so from the outside it looks like a ported box.

[@ChrisAudette]

What if you shared the airspace without the dividing wall with the resonance be bigger and deeper
