soundsplinter rl-p ported or sealed

stats wise the RL-ps are ported box subs

I thought the 15 stats were more suited to sealed, from what I have read

It was an argument of the many pointless idiotic ones on this forum where someone said the high Qts or something of the 15 made it more suited to sealed boxes versus the 12, its not like I made it up, but who knows around here, more posts are opinion rtather than fact half of the time

EBP-----This measurement is calculated by dividing Fs by Qes. The EBP figure is used in many enclosure design formulas to determine if a speaker is more suitable for a closed or vented design. An EBP close to 100 usually indicates a speaker that is best suited for a vented enclosure. On the contrary, an EBP closer to 50 usually indicates a speaker best suited for a closed box design. This is merely a starting point. Many well-designed systems have violated this rule of thumb! Qts should also be considered.

 

Q Parameters---------Qms, Qes, and Qts are measurements related to the control of a transducer's suspension when it reaches the resonant frequency (Fs). The suspension must prevent any lateral motion that might allow the voice coil and pole to touch (this would destroy the loudspeaker). The suspension must also act like a shock absorber. Qms is a measurement of the control coming from the speaker's mechanical suspension system (the surround and spider). View these components like springs. Qes is a measurement of the control coming from the speaker's electrical suspension system (the voice coil and magnet). Opposing forces from the mechanical and electrical suspensions act to absorb shock. Qts is called the 'Total Q' of the driver and is derived from an equation where Qes is multiplied by Qms and the result is divided by the sum of the same.

As a general guideline, Qts of 0.4 or below indicates a transducer well suited to a vented enclosure. Qts between 0.4 and 0.7 indicates suitability for a sealed enclosure. Qts of 0.7 or above indicates suitability for free-air or infinite baffle applications. However, there are exceptions!

 

that is what I go by usually

I don't know as for your answer, but when my 12 was sealed it just didn't do it. Now that it's ported, I love it!!

oh yeah I understand that, many of the newer subs have the capability to sound very good in both sealed and ported, but for the most part subs have a tendency to preform better in one or the other, thats all

I know, and im sure mine would probably come to life in a ported enclosure, its just that I dont have the room

i have tried both sealed and ported... i like ported better. Sealed didnt hit the lowend as much for me. however it lost some accuracy goin ported, but its bearable

I like the lowend that I get off of mine sealed, but im in a larger seald box 1.5 net apiece, so Im sacrificing some accuracy for a little more low end and output, I especially like the way my glass flexes an inch or so

I have 2 subs //content.invisioncic.com/y282845/emoticons/naughty.gif.94359f346c0f1259df8038d60b41863e.gif so ive got a tad more output
