Alpine Type-R SWR-10D4

Great cheap bass!!

These things are loud! For what you pay you get more then expected. Best bang for your buck. Put two of these in my 2014 sierra in a under the seat ported fox box and it bangs! Just make sure ou break them in correctly. I had 2 12 alpine type r shallows and fried them hit me too hard too soon. Alpine recommends 4-6 weeks of breakin in. Otherwise great overall!

Wow this thing hits like Thor. I already had a swr10d43-x and was very impressed with it. It is 600 watts rms. This new swr 105 is a positive step above at 1000 watts rms and just as clear if not clearer than before. I can't think of one bad thing about this sub unless it is the fact that I don't have room for two. Thanks again Sonic you are by far the best when it comes to electronics. Keep up the good work.

Durable is an understatement!

I am currently running two SWR-D2 Alpine subs with a RF T1500-1bdCP at 1 ohm with less than 1/3 gain. The birth sheet for the amp reads 1867 Watts RMS. With a OFC 1/0 gauge power and ground complimented with a 137 amp aftermarket alternator than states a 160 amp draw at 2000 rpm's with a constant 13.5 volt draw at an idle. in a slot ported box tuned at 33 hz with a gross internal volume of 1.33 cubic feet each. the T1500 is easily over powering the subs with the PEQX3 sub knob you have to be careful not to boost the bass too much because the voice coil will start slapping the magnet structure (which i do on accident all the time). I've been running these things at least 3 hours a day sometimes up to 6 hours continually at max blast for the last 4 months!!! very dependable and always stays cool (which you can feel on the cone)as long as you amp doesn't peak out. i have ran 6 different amps with these subs trying to find the perfect 1. always abused and driven to the full excursion capable of these subs at 20 mm one way which equals 1.5 inches from all in to all out. i think its closer to 2 inches but its impossible to measure, its just a guess based on the travel of the alpine emblems. my only complaint is the wire jumper terminals that come with the subs are unreliable because it hits so hard and the SPL is so high it pushes them out, however if you just use your speaker wire instead, it holds firm and tight forever. always remember that the output of the sub is relative to the amp pushing them and more important is the box they are in. i originally had them in a seal box of .75 cubic feet each but i enjoy more bass output with the same clarity tuned at 33 hz in my new box.i have spent over $2200 on my system and know i would not be where i am at now without alpine quality and sonic electonix great prices and never failing customer support and warranties.

Spend the extra money to get something better sonic offers

Pros - Clear sound with somewhat decent volume for the price.

Cons - Durability isn't that great. Other subs offered by sonic are much "louder" with the same or better sound quality and last much longer.

Sub is very clear. Not as "loud" as everyone claims. Broke in the sub for the correct break in period and after that the sub completely fried out. With just a few more dollars a much better sub can be purchased.

apline swr- 10d4

I am pushing a single swr-10d4 in my f-150 after destroying two other subs. I currently have 500 watts rms pushing my alpine but this beast needs more. The response, sound quality and durability of this sub is amazing. This sub is badass and I recommend it to anyone looking for better sound in their ride.

Great buy!!

Would recommend to anyone that is looking for good clean low bass and sound quality.

Best bang for the buck

Well worth the price compared to the competition. I'm running one of these in a custom box made for a 350Z. Simply amazing what this single 10" subwoofer can do. My amp is a Rockford Fosgate P400-1 and they are set for 2 ohms. The actual RMS output for the amp is 534 watts @ 2 ohms. I thought I might end up needing more but I'm very satisfied with the results. I highly recommend this sub.

Type R 10s

Great subs hit every note clean great value wish I could get 2 more

good sub but some probs

Sub sounds great hits the low notes perfectly but it seems to get loose sounding over extended playing has happened twice to me now glad that sonic has A1 customer support or this would have been a horrible turn out

Bump for your Buck

This subwoofer surprised the hell out of me for it's size and how much I paid for it. I have it in a sealed box and powered at 2ohms. It's getting 800watts RMS! This sub is almost as loud as my 2 12s and those were in a ported box and it less than half the size so I'm saving room too! Planning on getting a ported box for it so I can really see how loud it is! I recommend this for anyone needing to save room, money, and be loud at the same time!!!
