I've got Type R 5 1/4 comps in freshly made sealed door pods. I am not very impressed with the bass output. I'm running them off a Rockford 350s (approx 90W RMS per side) crossedover at 100Hz. I've got a KQ9 (graphic eq) and when I increase the 125Hz or 250Hz the speaker starts to distort almost right away. Should raise my crossover frequency a bit so I can boost the 125Hz a bit more in an attempt to get more kick out of them or do these speakers just suck for bass reprodution. I understand these are only 5 1/4 speakers but I had a pair of 5 1/4 Orion XTR comps in another vehicle in sealed kick pods and they seemed to punch harder than the Alpines, which supprises me because the alpines have a way beefier motor stucture. Any thoughts?

I had them installed in the stock location in the doors before. I built the pods specifically to get them into a sealed enclosure. Please don't tell me I spent three days for nothing. They sound better in the pods, I'm just supprised they don't have more kick.

you speakers are not ideally suited for ib, but will be better than a tiny little kick pod, you will get a ugly rise in frequency response between 150-300hz, right where you dont want it, and the little pod will take away all chances of getting any decent lower midbass, aka the bad sound you are getting, pods will give you better pathlegnth similarities but a little sealed pod creates a whole new bunch of problems, and i was wondering when you said they sounded better, how do they sound better,eg better tonality, stage, image etc, let me know

By sound better I meant fuller, deeper sound, a little bit clearer but i attribute that to a better speaker angle. I did notice an increase in the 200-300Hz range but I just dipped my 250HZ on my eq a bit. I want to get better bass drum impact out of them, what frequency rage would that be? Before they were solidly mounted in the stock location with a homemade spacer. The 100Hz 18db crossover is in my eq which unfortuantley I can't turn off. I'll turn on my amp crossover and slowly bring up the freq so I get a really steep slope and can boost the 125Hz on my EQ. That will probably help. I'm just comparing them in my mind to those orion's I had. I think I had them crossed over around 200Hz. They kicked pretty hard.

you will have along road ahead of you trying to get good sound out of a tiny pod, the kick you are looking for comes on the 125-300 hz range. what is very important is the lower harmonic of the frequncies you are lookig for, every freq. has a upper and lower harmonic, 200 hz upper harmonic is 400hz, lower harmonic 100hz, these harmonics are important as they give sound its fullness , this tiny pod you have is dramatically lowering the output of the lower freq harmonic therefor giving you sound that doesnt sound full, alot of experimenting is in your near future to get the sound you desire, the open ib application you had in your doors didnt lower the lower midbass harmonic as much as the pod so the sound would have seemed fuller, you just learned a valuble lesson in trade-offs in car audio, to gained something but you gave up something else
