I introduced the DEI 050331 Boom Mat 6.5" Round Slim Speaker perplex to secure an arrangement of 2 Alpine SPR-60 6-1/2" Coaxial 2-Way Type-R (back) and two SPR-60C 6-1/2" Component 2-Way midrange drivers (entryway) inside the lodge of my 2004 Saturn Ion 3.
The setup of the front entryway speaker hole is with the end goal that the establishment of post-retail speakers leaves a hole where turbulent air moves into the traveler compartment, through the speaker grille, when the windows are aired out. Where air can move, so can rain. I introduced one sets of the DEI 050331 Boom Mat 6.5" Round Slim Speaker astound to shield the speakers from dampness.
I have a 12" subwoofer introduced in the storage compartment, which makes significant acoustic weight. The over weight in the storage compartment was twisting the mid/low yield of my back deck-mounted Alpines. I introduced the DEI 050331 Boom Mat 6.5" Round Slim Speaker confuse to make a hindrance against the over weight.

Here is my criticism with respect to this establishment:
I enjoyed the alteration in sound in particular. The DEI 050331 Boom Mat 6.5" Round Slim Speaker astound enhanced my midrange determination an awesome arrangement, which gives me an enhanced fill in my high-pass band territory from 100 Hz to 1000 Hz. The change to my ear is an undeniable nearness of clearer, louder notes from piano, guitar, and horn. Since I don't depend on my inward satellite speakers to repeat bass range notes, I don't experience the ill effects of the bass misfortune that different analysts say. In any case, do consider that, since speakers are not all the same, nor are the natural states of every auto, the DEI 050331 Boom Mat 6.5" Round Slim Speaker puzzle won't be a one-measure fits-all application, in this manner requiring the installer to do some homework and, maybe, counts.
For instance, the directions for totally fixing the perplex walled in area with silicone isn't, really, the best exhortation. Since I run significant energy to my front sound stage, I need to permit some development for air from behind my speaker, else I am will utilize my volume of acoustical suspension vitality (which would be caught in the fixed fenced in area) to transform the perplex into a vibrating stomach, in this manner constricting my low-end flag. This isn't the ideal working condition for my front sound stage.
To illuminate, I figured a 20 mm port, which I cut into the base of the entryway mounted bewilder. I sanded the opening smooth, and utilized a different purpose of departure to go through the wiring. The port faces down to achieve my weatherproofing objective. The outcome was a prompt attractive impact.

In the back deck, I didn't port the bewilder walled in area. I needed aggregate separation of any trunk over weight because of subwoofer cone volume uprooting. In this application, I would concur that I lost a little low recurrence determination, however I picked up a significant change in midrange reaction. I would state, by tuning in, that the puzzle inclines off my range from 400 Hz to 100 Hz, with close constriction of the sound from 200 Hz to 100 Hz. Not a major ordeal, since I don't need my 6.5" speakers creating those frequencies.
By and large, for my application, the DEI 050331 Boom Mat 6.5" Round Slim Speaker confuse worked exceptionally well. While there might be a more reasonable answer for my listening condition, I am not planned for the time or cash to utilize my auto as a building test. This arrangement gave an extremely alluring change to my sound stage with the reward of having the capacity to build plenti fulness with less bending.
