let me begin out by saying if you cant discover jl items for under msrp, in most situations you might be able to do better with other items. ive been in the car music area for 15 decades and have used many manufacturers of subwoffers, among my preferred are kicker, innovator, ma music, down, mb quart.
ive owned/have a few jl woffers as well. if your looking for spl, want individuals to here you 3 prevents away and want to strike out windows, jl is most likely not going to satisfy you.
i recentely ordered a 10w7 for well under msrp so this was a big + for me. to be reasonable in “real world” examining, i tried diffrent containers,sealed and ported and diffrent adjusting for the ported.
for the made box i used a 1.3cuft, 1cuft, and also the recomended 1.25 cuft. each of these offered achievement for me with the 1.25cuft providing the best over all sq. if i were to use this w7 in a seald box, i would use it in a 1.125cuft packed with poly load for my preference.
now here is where i spent a lot of cash, i designed 4 diffrent containers. when the examining was done, i discovered that 1.6 cuft was the best air place and adjusting around 34hz proved helpful best and offered better outcomes than the recomended box. also i discovered that the recomended slot sise (1.5″ wide) was not enough. there was too much air disturbance. re-tuning the box with a 1.75″ large slot set this issue and included a little more out put vs. the 1.5″wide slot.
i operated this sub with the jl 5001 that a buddy let me use and it was excelent. this however was not enough energy so i smashed out my 81000d which at 3 ohms is 750 rms at 12.5v and at 14.4v 995 h rms.(bench comfirmed by landis tech) and still this 10w7 will still take a little more energy. i do not contend in spl with this sub but it did produce over 138 db in a 93 cutlass with the back outdoor patio cut out of it. i have all mb quart q sequence mids and peaks in the car and using this sub now for over a season, i have won 4 first position, 2 second and 5 3rd position in regional sq fight one of which (first place) was an iasca occurrence at a regional soundadvice.
for you “bass heads” this sub with the energy iam delivering it visitors tougher than just about ANY individual 10″ i have ever used in 15 decades of car audio
for the sq folks that work at higher energy amounts, this is the BEST looking individual 10″ sub i have used currently.
if you can select one of these up for under 450$ they are value every bit
