    Hello colleagues - the bus rides nice, but it's worse to play. The radio is a factory Cabasse Auditorium with a changer, no navi. I have now added the parrot mki9200 set and I would like to listen to good music, but if I can't complain about the cleanliness, the very weak bass is a downside for me. Mounting the box or tube is pointless for me because of the unwillingness to waste space.
    I checked and 13cm speakers are originally installed in the door. I would like to exchange them for something that will give me bass and not just a substitute. Of course, it's not that the kennel shake because the roof will fall into poppy seeds :-)
    I thought I could damp the door and put on better speakers. Adding an amplifier also falls - well, unless it used to be. I thought to replace the speakers in the front door and leave the back as it is. Maybe some other idea. Now the speaker issue - I have no idea what to buy. Go further in 13cm or can it give distance and give 16cm? The loudspeaker company does not matter to me because I do not know it - I do not know how cheap boschmans play, or peyings or something else. On the other hand, if they can be decent they should be called as they want. I don't want to pay for the name of the company. Oh - for a moment I set up my Sony xplod - something probably about 30W and there was no frenzy and certainly not bass. Budget? As little as possible - max 400-500 PLN

    Invest this money better in door preparation, i.e. improving the fastening of the speakers (MDF distance firmly bolted to the metal sheet), damping with mats and closing of technological holes. Without the above you won't get bass even if you spend 2x as much as you have to invest to buy speakers.

    OK - of course I will. In order not to delay questions in the future:
    - what mats \ tapes or plates to use for damping? I remember that there used to be some bitumen mats, but I think they can crack from the cold - yes? Once done well and I would like to choose the right material. The next question I would like to ask are the speakers in which to invest later, but I think in this situation the question may be a false start because I assume that the dynamics of the sound will improve after the door is ready. Nevertheless, when I sow a seed asking for speakers ...

    Look at the butyl mats STP, CtK, GMS, Dynamat, Vibrofiltr, or Hollywood.

    Thanks, I will cover the door and we will probably return to the speakers - unless the improvement is so great that you will not need :-)

    I have already ordered mats and I will cover this topic during the weekend. I wonder if in the budget I proposed I will choose some interesting speakers. Can you recommend something? I prefer to prepare substantive in case I have to look for speakers on Monday. What to look for And the question is 130 or 160?

    The mission accomplished - the door silenced - there is indeed improvement, but still no shawl. I am still thinking about the speakers.

    I do not know if I can see correctly, but you have sealed the mounting holes with a mat without blinding them with sheet metal or other rigid material, which doesn't give much - a passive membrane is created.
    As for speakers, of course, it's much better to go in 16cm when it comes to bass. I bought mac audio 16.2 for citroen xsara from cheap father that year. Admittedly two-way, which is obviously a disadvantage, but such speakers were cheap and in the nearest store that's why they were chosen. Amazingly they played ("played" at this price) ;) ) and on the radio itself (after turning the sopranos to eq on the radio), the bass really was not lacking.
    From others, you can look at Pioneer, Blaupunkt, which also have cheap speakers. All in all, Boschman have heard a few models and honestly some of them will gently play, others will sound like a whole.
    Generally, what I recommend to you with a small amount of money go to the nearest store, take some cheap 16cm and test them in your car. You can always give back within a week.
    And the most important improvement is attenuation.

    This large hole is concave because this is the design of the sides of the door after putting it on it presses the mate and I think that there are no movements. Still an idea that I could instead peel off the original door fill. In my car, this is not a foil, but a profiled, hard upholstery. Maybe if I put on a good mat and put it on, it would be better. As for the speakers - somewhere I read something about helix speakers or something similar. During the week, I will order a distance for this car at 16 cm and improve damping. What to look for near the speakers? Low and medium tone? One way?

    I thought about these HELIX B 62C

    You know the best 2 or 3-way set, but don't lie to yourself, you won't find anything at this price.
    Helixes, although a good company is the cheapest loudspeakers for me. Unless you listen to them in the dark, don't take them.

    I understand. I would like someone to recommend specific models that you have heard and with a hand on your heart can be recommended. I can go to the mediamarkt today and see what they have. Buying from them is probably + 40% dreaming like in another store, but at least you can touch the goods.

    There is muffled, assumed distances from mdf to 16cm + Morel maximo 6.2 speakers - The game sounds better than I expected and I think it will be even better. After some time, muffling the back door and changing the speakers + adding the amplifier.

    No morel gives advice, only by buying them you probably didn't make it together with damping in the assumed amount of PLN 400-500 ;)
    At this time, I strongly advise against putting anything on, I would even recommend cutting off the distortion. Put a good class amplifier on the front and it should be ok. Additionally, you can invest in some interesting radio.

    As it happens in life - it comes out differently - more expensive than at the beginning. Muting the door + speakers + spacers + screws + cable = less than PLN 800

    First I would search the internet - enter the parameters dimensions and you have a ready list of equipment that matches the requirements. Look at centrumaudio.pl/103-glosniki-i-subwoofery and look at indicative prices and producers. Read the reviews and only then go shopping. And even if you find something media, then look at centrumaudio, you will definitely find cheaper and with free delivery.

    Tell me how many damping mats did you get and did you glue the doors and upholstery? Well done damping is nicely documented at basser.pl, but I have too few points to provide a link :)

    I will look for bills and photos later. I have taken a photo of how I got it and how it is at the end. It seems to me that soundproofing came out about 3.5 - 4m2 on a couple of doors in the front.

Topic summary

✨ The discussion revolves around upgrading the factory-installed Cabasse Auditorium 13cm door speakers in a Renault Espace IV to enhance bass and overall sound quality. The user expresses dissatisfaction with the weak bass and seeks advice on improving the audio experience without sacrificing space. Recommendations include preparing the doors with damping materials to improve speaker performance, with suggestions for butyl mats from brands like STP, Dynamat, and others. The user considers replacing the speakers with larger 16cm models for better bass response, with specific mentions of brands like Pioneer, Blaupunkt, and Morel. The conversation also touches on the importance of proper installation and the potential need for an amplifier to further enhance sound quality.

FAQ

TL;DR: For Renault Espace IV, door work + 16 cm fronts wins: "soundproofing came out about 3.5–4 m²" and bass improved. [Elektroda, tomrom1985, post #17260238] Why it matters: This FAQ shows how to get fuller bass from the factory Cabasse setup without adding a trunk sub, saving space and money; it’s for DIY car‑audio upgraders seeking practical, proven steps.

Quick Facts

How do I get better bass from the Cabasse Auditorium without adding a sub?

Start with door preparation. Use rigid MDF spacers, bolt them to the metal, add butyl mats, and close service holes. This stiffens the baffle and seals the cavity, boosting mid‑bass. As one expert put it, “Without the above you won’t get bass.” [Elektroda, powalla, post #16700332]

13 cm vs 16 cm speakers—what fits and sounds better in Espace IV?

The car ships with 13 cm fronts, but moving to 16 cm on MDF spacers improves bass reach and punch. One owner installed 16 cm Morel Maximo 6.2 with spacers and reported the upgrade played better than expected. This path keeps the factory look while adding authority. [Elektroda, tomrom1985, post #16719836]

What damping material should I use—bitumen or butyl?

Use quality butyl mats. They adhere well, don’t crack in cold, and add controlled mass. Community‑trusted brands include STP, CtK, GMS, Dynamat, Vibrofiltr, and Hollywood. Avoid old bitumen sheets that can harden and detach. Proper damping underpins every other improvement. [Elektroda, powalla, post #16700355]

How much damping do I need for the front doors?

Plan approximately 3.5–4.0 m² of butyl mats for both front doors. That coverage lets you treat the outer skin, reinforce the inner skin, and tame panel resonances. A user who measured their job reported this exact range after finishing. [Elektroda, tomrom1985, post #17260238]

Do I need an external amplifier with the factory head unit?

It helps. After upgrading to quality 16 cm components, adding a good front‑stage amplifier cleans dynamics and reduces distortion. The advice in‑thread: prioritize a proper amp on the fronts and consider a better head unit later if desired. [Elektroda, Twu, post #16722348]

What did this upgrade actually cost someone?

Reported spend: under PLN 800 for door damping, MDF spacers, speakers, screws, and cable. That exceeded the initial PLN 400–500 target but delivered a clear audible improvement in bass and clarity. Budget a cushion for incidentals. [Elektroda, tomrom1985, post #16722353]

Any pitfalls when sealing door holes during damping?

Yes. Don’t just skin over large service holes with flexible mat. That can create a passive‑membrane effect, reducing bass and causing panel movement. Back large openings with rigid sheet or rings, then apply mats. This stabilizes the panel and improves output. [Elektroda, Twu, post #16703682]

Are Helix B 62C or budget brands (Pioneer, Blaupunkt, Boschmann) good here?

Experiences vary. One poster felt entry Helix units underperformed for the price and suggested test‑fitting affordable 16 cm sets locally. Quote: “the most important improvement is attenuation.” Prioritize damping first, then choose based on in‑car tests and return policy. [Elektroda, Twu, post #16703682]

How do I mount 16 cm speakers where 13 cm units were?

Use CNC‑cut MDF spacers sized for 16 cm. Bolt the rings firmly to the metal door, decouple as needed, and ensure clear window travel. This strengthens the baffle and positions the driver correctly behind the grille. Seal edges after mounting. [Elektroda, powalla, post #16700332]

What’s a passive membrane in car doors?

A passive membrane occurs when a flexible panel vibrates like an unintended speaker. In doors, thin mat over a large hole can act this way. It steals energy, blurs bass, and raises distortion. Add rigid backing before matting to prevent it. [Elektroda, Twu, post #16703682]

Does the Parrot MKi9200 improve bass on the Cabasse system?

The MKi9200 adds Bluetooth hands‑free and media convenience, but it doesn’t fix bass by itself. The thread starter had the kit installed yet still found the low‑end weak until door work and speaker upgrades were done. [Elektroda, tomrom1985, post #16700288]

Any EQ tips if I’m staying on the factory radio for now?

After upgrading speakers, reduce harsh treble on the radio EQ to balance the response. One user noted stronger perceived bass after lowering “sopranos.” Avoid boosting bass heavily; fix the doors first, then fine‑tune EQ subtly. [Elektroda, Twu, post #16703682]

Can you share a simple 3‑step how‑to for door prep?

  1. Bolt MDF spacers to the metal door for rigidity.
  2. Apply butyl mats to outer and inner skins; close service holes.
  3. Refit trim, ensuring no panel buzz and full window clearance. “Without the above you won’t get bass.” [Elektroda, powalla, post #16700332]

Should I also upgrade the rear doors on an Espace IV?

Yes, once fronts are done. The owner planned to damp and upgrade the rears later, after hearing a big front‑stage improvement. Prioritize fronts and power first, then match rears for tonal consistency. [Elektroda, tomrom1985, post #16719836]
